• Java - Set Color by switch case function

  - by user369150

  I want to set the color of the TextView by the function getcolorss. I tried a lot of different ways but i cant get in it. Please help me i think the solution is easy. import java.awt.*; import android.graphics.Color; public class test extends Activity { TextView text1 = (TextView) findViewById(R.id.text1); text1.setTextColor(getcolorss(1)); public Color getcolorss(int x) { switch(x) { case 1: return Color.BLUE; case 2: return Color.RED; } } }

• code setOnClickListener for multiple TextViews

  - by user2870583

  I have 40+ TextViews and I want to add click events on them, but I try to do it "shortly" : final GridLayout myGL; myGL = (GridLayout) v0725.findViewById( R.id.tab1 ); for( int i = 0; i < myGL.getChildCount(); i++ ) if ( getResources().getResourceEntryName(((TextView) myGL.getChildAt(i)).getId()).indexOf("v")==0 ) { ((TextView) myGL.getChildAt(i)).setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.v("edf", getResources().getResourceEntryName(((TextView) myGL.getChildAt(i)).getId())); } }); }; But Eclipse stops me on the Log.v line, because i should be final (but I can't) any tips?

• Example: Communication between Activity and Service using Messaging

  - by Lance Lefebure

  I couldn't find any examples of how to send messages between an activity and a service, and spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the service is running, it increments a number at 10Hz. If the activity is bound to the service, it will display the current value. Data is transferred as an Integer and as a String so you can see how to do that two different ways. There are also buttons in the activity to send messages to the service (changes the increment-by value).

  This is my code: package com.example.userpage; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class UserPage extends Activity { String tv,tv1; EditText name,pass; TextView x,y; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.widget44); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { name.setText(" "); pass.setText(" "); } }); x = (TextView) findViewById(R.id.widget46); y = (TextView) findViewById(R.id.widget47); name = (EditText)findViewById(R.id.widget41); pass = (EditText)findViewById(R.id.widget42); Button button1 = (Button) findViewById(R.id.widget45); button1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { tv= name.getText().toString(); tv1 = pass.getText().toString(); x.setText(tv); y.setText(tv1); } }); } } And this is my log cat: 02-16 12:24:30.488: DEBUG/AndroidRuntime(973): >>>>>>>>>>>>>> AndroidRuntime START <<<<<<<<<<<<<< 02-16 12:24:30.488: DEBUG/AndroidRuntime(973): CheckJNI is ON 02-16 12:24:31.208: DEBUG/AndroidRuntime(973): --- registering native functions --- 02-16 12:24:33.498: DEBUG/AndroidRuntime(973): Shutting down VM 02-16 12:24:33.537: DEBUG/dalvikvm(973): Debugger has detached; object registry had 1 entries 02-16 12:24:33.537: INFO/AndroidRuntime(973): NOTE: attach of thread 'Binder Thread #3' failed 02-16 12:24:34.917: DEBUG/AndroidRuntime(981): >>>>>>>>>>>>>> AndroidRuntime START <<<<<<<<<<<<<< 02-16 12:24:34.927: DEBUG/AndroidRuntime(981): CheckJNI is ON 02-16 12:24:35.617: DEBUG/AndroidRuntime(981): --- registering native functions --- 02-16 12:24:38.029: INFO/ActivityManager(67): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.example.userpage/.UserPage } 02-16 12:24:38.129: DEBUG/AndroidRuntime(981): Shutting down VM 02-16 12:24:38.160: DEBUG/dalvikvm(981): Debugger has detached; object registry had 1 entries 02-16 12:24:38.168: INFO/AndroidRuntime(981): NOTE: attach of thread 'Binder Thread #3' failed 02-16 12:25:12.028: DEBUG/AndroidRuntime(990): >>>>>>>>>>>>>> AndroidRuntime START <<<<<<<<<<<<<< 02-16 12:25:12.038: DEBUG/AndroidRuntime(990): CheckJNI is ON 02-16 12:25:12.708: DEBUG/AndroidRuntime(990): --- registering native functions --- 02-16 12:25:15.178: DEBUG/dalvikvm(176): GC_EXPLICIT freed 114 objects / 5880 bytes in 115ms 02-16 12:25:15.318: DEBUG/PackageParser(67): Scanning package: /data/app/vmdl25170.tmp 02-16 12:25:15.588: INFO/PackageManager(67): Removing non-system package:com.example.userpage 02-16 12:25:15.597: INFO/ActivityManager(67): Force stopping package com.example.userpage uid=10036 02-16 12:25:15.648: INFO/Process(67): Sending signal.

• Displaying and updating score in Android (OpenGL ES 2)

  - by user16547

  I'm using a FrameLayout where I have a GLSurfaceView at the bottom and a few Views on top of it. One of those Views is a TextView that displays the current score. Here's how I'm updating the score TextView based on what happens in my game loop: whenever an event happens that increases the score, I call activity.runOnUiThread(updater), where activity is the activity that has the above FrameLayout (my main game activity) and updater is just a Runnable that increments the score. From my understanding, using runOnUiThread() from the OpenGL thread is standard practice - otherwise you'll get an exception, I can't remember its name. The problem is that there's a very noticeable lag between the event and the score update. For example the character gets a coin, but the coin count is not updated quickly. I tried summing all the score events from my game loop and calling runOnUiThread() only once per loop, but it doesn't seem to make much of a difference - the lag is still noticeable. How can I improve my design to avoid this lag?

• Android - Custom Adapter Problem

  - by Ryan

  Hello, I seem to be having a problem with my Custom Adapter view. When I display the list, it only displays a white screen. Here is how it works: 1.) I send a JSON request 2.) populate the ArrayList with the returned results 3.) create a custom adapter 4.) then bind the adapter. Here is steps 2-4 private void updateUI() { ListView myList = (ListView) findViewById(android.R.id.list); itemList = new ArrayList(); Iterator it = data.entrySet().iterator(); while (it.hasNext()) { //Get the key name and value for it Map.Entry pair = (Map.Entry)it.next(); String keyName = (String) pair.getKey(); String value = pair.getValue().toString(); if (value != null) { ListItem li = new ListItem(keyName, value, false); itemList.add(li); } } CustomAdapter mAdapter = new CustomAdapter( mContext, itemList); myList.setAdapter(mAdapter); //Bind the adapter to the list //Tell the dialog it's cool now. dismissDialog(0); //Show next screen flipper.setInAnimation(inFromRightAnimation()); flipper.setOutAnimation(outToRightAnimation()); flipper.showNext(); } And here is my CustomAdapter class: import java.util.List; import android.R.color; import android.content.Context; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.RelativeLayout; import android.widget.TextView; class MyAdapterView extends RelativeLayout { public MyAdapterView(Context c, ListItem li) { super( c ); RelativeLayout rL = new RelativeLayout(c); RelativeLayout.LayoutParams containerParams = new RelativeLayout.LayoutParams( ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT); rL.setLayoutParams(containerParams); rL.setBackgroundColor(color.white); ImageView img = new ImageView (c); img.setImageResource(li.getImage()); img.setPadding(5, 5, 10, 5); rL.addView(img, 48, 48); TextView top = new TextView(c); top.setText(li.getTopText()); top.setTextColor(color.black); top.setTextSize(20); top.setPadding(0, 20, 0, 0); rL.addView(top,ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); TextView bot = new TextView( c ); bot.setText(li.getBottomText()); bot.setTextColor(color.black); bot.setTextSize(12); bot.setPadding(0, 0, 0, 10); bot.setAutoLinkMask(1); rL.addView(bot,ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); } } public class CustomAdapter extends BaseAdapter { private Context context; private List itemList; public CustomAdapter(Context c, List itemL ) { this.context = c; this.itemList = itemL; } public int getCount() { return itemList.size(); } public Object getItem(int position) { return itemList.get(position); } public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ListItem li = itemList.get(position); return new MyAdapterView(this.context, li); } } Does anyone have any idea why this displays a white screen upon completion?? Thanks in advance!

• Changing the background color of a view in real-time.

  - by Tarmon

  Hey Everyone, I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that. I want to be able to change the background color of the first View based on it's position in the ListView. Below is what I have at this point but it doesn't seem to due anything. public class Routes extends ListActivity { String[] ROUTES; TextView selection; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ROUTES = getResources().getStringArray(R.array.routes); setContentView(R.layout.routes); setListAdapter(new IconicAdapter()); selection=(TextView)findViewById(R.id.selection); } public void onListItemClick(ListView parent, View v, int position, long id) { selection.setText(ROUTES[position]); } class IconicAdapter extends ArrayAdapter<String> { IconicAdapter() { super(Routes.this, R.layout.row, R.id.label, ROUTES); } } public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); View row = inflater.inflate(R.layout.row, parent, false); TextView label = (TextView) row.findViewById(R.id.label); label.setText(ROUTES[position]); View icon = (View) row.findViewById(R.id.icon); switch(position){ case 0: icon.setBackgroundColor(R.color.Red); break; case 1: icon.setBackgroundColor(R.color.Red); break; case 2: icon.setBackgroundColor(R.color.Green); break; case 3: icon.setBackgroundColor(R.color.Green); break; case 4: icon.setBackgroundColor(R.color.Blue); break; case 5: icon.setBackgroundColor(R.color.Blue); break; case 6: icon.setBackgroundColor(R.color.Gray); break; case 7: icon.setBackgroundColor(R.color.Yellow); break; case 8: icon.setBackgroundColor(R.color.Brown); break; case 9: icon.setBackgroundColor(R.color.Brown); break; case 10: icon.setBackgroundColor(R.color.Brown); break; case 11: icon.setBackgroundColor(R.color.Purple); break; case 12: icon.setBackgroundColor(R.color.Red); break; case 13: icon.setBackgroundColor(R.color.Gold); break; case 14: icon.setBackgroundColor(R.color.Orange); break; } return(row); } } Any input is appreciated and if you have any questions don't hesitate to ask!

• Android onClickListener options and help on creating a non-static array adapter

  - by CoderInTraining

  I am trying to make an application that gets data dynamically and displays it in a listView. Here is my code that I have with static data. There are a couple of things I want to try and do and can't figure out how. MainActivity.java package text.example.project; import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends ListActivity { //declarations private boolean isItem; private ArrayAdapter<String> item1Adapter; private ArrayAdapter<String> item2Adapter; private ArrayAdapter<String> item3Adapter; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Collections.sort(ITEM1); Collections.sort(ITEM2); Collections.sort(ITEM3); item1Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM1); item2Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM2); item3Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM3); setListAdapter(item1Adapter); isItem = true; ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // When clicked, show a toast with the TextView text if (isItem) { //ITEM1.add("another\n\t" + Calendar.getInstance().getTime()); Collections.sort(ITEM1); item2Adapter.notifyDataSetChanged(); setListAdapter(item2Adapter); isItem = false; } else { item1Adapter.notifyDataSetChanged(); setListAdapter(item1Adapter); isItem = true; } Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); } }); } // need to turn dynamic static ArrayList<String> ITEM1 = new ArrayList<String> (Arrays.asList( "ITEM1-1", "ITEM1-2" )); static ArrayList<String> ITEM2 = new ArrayList<String> (Arrays.asList( "ITEM2-1", "ITEM2-2" )); static ArrayList<String> ITEM3 = new ArrayList<String> (Arrays.asList("ITEM3-1", "ITEM3-2")); } list_item.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" > </TextView> What I want to do is first pull from a dynamic source. I need to do what is almost exactly like this tutorial... http://androiddevelopement.blogspot.in/2011/06/android-xml-parsing-tutorial-using.html ... however, I can't get the tutorial to work... I also would like to know how I can make the list item clicks so that if I click on "ITEM1-1" it goes to the menu "ITEM2-1" and "ITEM2-2". and if "ITEM1-2" is clicked, then it goes to the menu with "ITEM3-1" and "ITEM3-2"... I am totally a noob at this whole android development thing. So any suggestions would be great!

• Using AsyncTask, but experiencing unexpected behaviour

  - by capcom

  Please refer to the following code which continuously calls a new AsyncTask. The purpose of the AsyncTask is to make an HTTP request, and update the string result. package room.temperature; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.concurrent.ExecutionException; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import android.app.Activity; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class RoomTemperatureActivity extends Activity { String result = null; StringBuilder sb=null; TextView TemperatureText, DateText; ArrayList<NameValuePair> nameValuePairs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TemperatureText = (TextView) findViewById(R.id.temperature); DateText = (TextView) findViewById(R.id.date); nameValuePairs = new ArrayList<NameValuePair>(); for (int i = 0; i < 10; i++) { RefreshValuesTask task = new RefreshValuesTask(); task.execute(""); } } // The definition of our task class private class RefreshValuesTask extends AsyncTask<String, Integer, String> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected String doInBackground(String... params) { InputStream is = null; try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://mywebsite.com/roomtemp/tempscript.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection" + e.toString()); } try { BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); sb = new StringBuilder(); sb.append(reader.readLine()); is.close(); result=sb.toString(); } catch(Exception e) { Log.e("log_tag", "Error converting result " + e.toString()); } return result; } @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); } @Override protected void onPostExecute(String result) { super.onPostExecute(result); //System.out.println(result); setValues(result); } } public void setValues(String resultValue) { System.out.println(resultValue); String[] values = resultValue.split("&"); TemperatureText.setText(values[0]); DateText.setText(values[1]); } } The problem I am experiencing relates to the AsyncTask in some way or the function setValues(), but I am not sure how. Essentially, I want each call to the AsyncTask to run, eventually in an infinite while loop, and update the TextView fields as I have attempted in setValues. I have tried since yesterday after asking a question which led to this code, for reference. Oh yes, I did try using the AsyncTask get() method, but that didn't work either as I found out that it is actually a synchronous call, and renders the whole point of AsyncTask useless.

• getView only shows Flagged Backgrounds for drawn Views, It does not show Flagged Background when scroll to view more items on list

  - by Leoa

  I am trying to create a listview that receives a flagged list of items to indicate a status to the user. I have been able to create the flag display by using a yellow background (see image at bottom). In Theory, the flagged list can have many flagged items in it. However in my app, only the first three flagged backgrounds are shown. I believe this is because they are initially drawn to the screen. The Flagged background that are not drawn initially to the screen do not show. I'd like to know how to get the remaining flags to show in the list. ListView Recycling: The backgrounds in the listView are being recycled in getView(). This recycling goes from position 0 to position 9. I have flags that need to match at positions 13, 14 and so on. Those positions are not being displayed. listView.getCheckedItemPositions() for multiple selections: This method will not work in my case because the user will not selected the flags. The flags are coming from the server. setNotifyOnChange() and/or public virtual void SetNotifyOnChange (bool notifyOnChange): I'm not adding new data to the list, so I don't see how this method would work for my program. Does this method communicate to getview when it is recycling data? I was unable to find an answer to this in my research. public void registerDataSetObserver: This may be overkill for my problem, but is it possible to have an observer object that keeps track of the all the positions in my items list and in my flag list no matter if the view is recycled and match them on the screen?

• Custom fonts, ellipsis on MultiLine TextViews, Glyphs and glitches.

  - by Samuh

  I am required to use custom fonts in my application. Problem: For ListViews that contain rows with Multi-Line TextViews having ellipsize property set to true, I can see some illegible characters after the ellipsis. Apparently Android pads the String(in TextView) with some characters unknown to my custom font. Single line TextView seem to work just fine. What is the best way to hide these characters or remove the padding? Thanks.

• custom listview adapter getView method being called multiple times, and in no coherent order

  - by edzillion

  I have a custom list adapter: class ResultsListAdapter extends ArrayAdapter<RecordItem> { in the overridden 'getView' method I do a print to check what position is and whether it is a convertView or not: @Override public View getView(int position, View convertView, ViewGroup parent) { System.out.println("getView " + position + " " + convertView); The output of this (when the list is first displayed, no user input as yet) 04-11 16:24:05.860: INFO/System.out(681): getView 0 null 04-11 16:24:29.020: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43d415d8 04-11 16:25:48.070: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.110: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.710: INFO/System.out(681): getView 0 android.widget.RelativeLayout@43d415d8 04-11 16:25:50.251: INFO/System.out(681): getView 1 null 04-11 16:26:01.300: INFO/System.out(681): getView 2 null 04-11 16:26:02.020: INFO/System.out(681): getView 3 null 04-11 16:28:28.091: INFO/System.out(681): getView 0 null 04-11 16:37:46.180: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.091: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.730: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43cff8f0 AFAIK, though I couldn't find it stated explicitly, getView() is only called for visible rows. Since my app starts with four visible rows at least the position numbers cycling from 0-3 makes sense. But the rest is a mess: Why is getview called for each row four times? Where are these convertViews coming from when I haven't scrolled yet? I did a bit of reseach, and without getting a good answer, I did notice that people were associating this issue with layout issues. So in case, here's the layout that contains the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/pageDetails" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:drawSelectorOnTop="false" /> </LinearLayout> and the layout of each individual row: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="108dp" android:padding="4dp"> <ImageView android:id="@+id/thumb" android:layout_width="120dp" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_marginRight="8dp" android:src="@drawable/loading" /> <TextView android:id="@+id/price" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentBottom="true" android:singleLine="true" /> <TextView android:id="@+id/date" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:paddingRight="4dp" android:singleLine="true" /> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="17dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:paddingRight="4dp" android:layout_alignWithParentIfMissing="true" android:gravity="center" /> Thank you for your time

• UITextView Scrolling - Artificial Limit

  - by Matt Winters

  I have a UITextView with a height of let's say 300. What I would like is when the typed text gets to the half way point, for the scrolling to start as if it were at the bottom of the textView. Basically I would like to programmatically set the point within the textView for scrolling to begin. Any ideas? Thanks.

• Scale background image to wrap content of layout

  - by bjg222

  I have a layout that contains some text fields and has a background image that's displayed at the top of my activity. I'd like the background image to scale to wrap the content (don't care about aspect ratio). However, the image is larger than content, so the layout instead wraps the background image. Here's my original code: <RelativeLayout android:layout_width="fill_parent" android:id="@+id/HeaderList" android:layout_gravity="top" android:layout_height="wrap_content" android:background="@drawable/header"> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/NameText" android:text="Jhn Doe" android:textColor="#FFFFFF" android:textSize="30sp" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:paddingLeft="4dp" android:paddingTop="4dp" /> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:textColor="#FFFFFF" android:layout_alignParentLeft="true" android:id="@+id/HoursText" android:text="170 hours" android:textSize="23sp" android:layout_below="@+id/NameText" android:paddingLeft="4dp" /> </RelativeLayout> After searching through some other questions, I found these two: How to wrap content views rather than background drawable? Scale a Drawable or background image? Based on this, I created a FrameLayout w/ an ImageView showing the background. Unfortunately, I still can't get it to work. I want the height of the background image to shrink/expand w/ the size of the text views, but with the FrameLayout, the ImageView fits to the size of it's parent, and I can't find a way to make the parent fit to the size the text view layout. Here's my updated code: <FrameLayout android:layout_width="fill_parent" android:layout_height="wrap_content" > <ImageView android:src="@drawable/header" android:layout_width="fill_parent" android:scaleType="fitXY" android:layout_height="fill_parent" /> <RelativeLayout android:layout_width="fill_parent" android:id="@+id/HeaderList" android:layout_gravity="top" android:layout_height="wrap_content" > <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/NameText" android:text="John Doe" android:textColor="#FFFFFF" android:textSize="30sp" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:paddingLeft="4dp" android:paddingTop="4dp" /> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:textColor="#FFFFFF" android:layout_alignParentLeft="true" android:id="@+id/HoursText" android:text="170 hours" android:textSize="23sp" android:layout_below="@+id/NameText" android:paddingLeft="4dp" /> </RelativeLayout> </FrameLayout> Does anybody have any suggestions for how best to make an image scale to the size of the contents of some layout? I'm not concerned with the aspect ratio of the image, as it won't matter, I just want it to fill the background. Thanks!

• How can I make these images download on a seperate thread?

  - by Andy Barlow

  Hello!! I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really apreciated. Thank-you kindly. Andy Barlow private class CatalogAdapter extends ArrayAdapter { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter.
