  • How to use ColorDrawable with ImageView?

    - by user246114
    Hi, I have a layout with an ImageView defined like: <ImageView android:layout_width="45dip" android:layout_height="45dip" android:scaleType="fitXY" /> now I just want to set the imageview to be a static color, like red or green. I'm trying: ColorDrawable cd = new ColorDrawable("FF0000"); cd.setAlpha(255); ImageView iv = ...; iv.setImageDrawable(cd); the imageview is just empty though, no color. The 45dip space is being used up though. What do I need to do to get the color to be rendered? Thanks

  • Magento layout override!

    - by Farid
    Hi, I'm kind of new to the Magento, so forgive me for my stupid question! As I understand the whole concept of Magento is base on overriding the basic components that's are available with in the Magento. So based on my understanding I've decided to update the layout of onepage checkout in Magento. I've created my own layout and in the config file set that my layout updates the checkout module layout. But the problem is it's actually does not update the base layout, it replaces it self with base layout! Should it be act like this or am I wrong?!

  • Issue with button text shifting

    - by Fizz
    I'm having this odd issue. I have these buttons where the button's text is shifted downward upon certain actions. For example, I have a spinner with choices and one of the choices makes some buttons invisible while others are made visible. When I choose these, the buttons made visible all have their text shifted downward. Nothing else is shifted, just the text on the buttons. I've tried this on 1.5 and it works fine, no text is shifted, but I have issues with 2.1 and I really cannot figure it out. Any ideas or help would be great. Thanks.

    When I try to use layout_above to position a view above another view, it can't find the ID if it's not in the same XML file. I'm adding my XML files at run time but I still want to be able to position them relative to eachother. Any suggestions?

  • Actionbar scherlock is not refreshed when the orientation is changed

    - by SavasCinar
    I use Sherlock action bar in my application. I used "ifRoom|withText" feature in my menu. If I test my code in portrait mode, I can see only icon and if I rotate orientation to landscape, still I see only icon. On the other hand, if I run with landscape, I can see text and icon on portrait and landscape. This means that When the screen is rotated, action bar is not refreshed. How can I fix? In menu, I have android:showAsAction="ifRoom|withText" Also I used this line in my manifest file to fixed android:configChanges="keyboardHidden|orientation|screenSize" but it didn't work. And I run my code android 2.3 Also I used fragment in my activity, FragmentManager fm = getSupportFragmentManager(); ft = fm.beginTransaction(); mFragment1 = fm.findFragmentByTag("f1"); if (mFragment1 == null) { mFragment1 = new MenuFragment(); ft.add(mFragment1, "f1"); } ft.commit();

  • Expandable listview with selectall checkbox : group itemclick and scrolling bug

    - by Samet
    I have an ExpandableListView with a checkbox next to group name and when expanded, child items with checkbox as well. Let's suppose I have 4 groups with 50 childs. When a group is expanded, and I click on select all checkbox, everything works fine, all checkbox are selected and keep their state if I scroll. But if I scroll untill the last child of the list, scrolling gets buggy after that ( scrolling to the top and then touching the screen to stop the scrolling doesn't work anymore), clicking on group doesn't work anymore too, untill I click on selectall checkbox again. Clicking on a child checkbox does nothing, I must click on selectall checkbox for everything to work. I changed Focusable state of the child checkbox, group checkbox and tried many ways, but I can not find a solution to this. Do you have an idea of where it is coming from?

  • Using too much memory in C/NDK?

    - by rebeccamaher
    I've recently found out there is no hard limit to how much memory you can allocate in C/NDK on Android. This is in contrast to Java where the limit is ~24Mb. I'm working on a few apps that could greatly benefit from using about ~50Mb total. Is this far too much memory to use? Does anyone have any experience with developing apps that go above the Java limit and what impact this has across devices? Obviously, I don't want to kill all background apps by consuming too much memory and I know the Android devs suggest not using too much memory but limiting all apps to ~24Mb is very limiting to certain kinds of apps. I've seen a few Android games recently that say they use ~256Mb. I'm planning to use about 50Mb total for my app. Does this sound reasonable in terms of stability across devices that have a limit of 24Mb?

  • How to show own view in Spinner Widget instead of Text View?

    - by Janusz
    I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item. It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row. I simply want to show an individual icon left from the spinner text for each item in the list.

  • Show transparent color filter on a View after clicking it

    - by Maarten
    So. You know how when you click a post in the Google+ app, the entire View becomes blue. I want to do that as well, but with an ImageView. I have the following code snippet, setting the actual image as the background and the selector as the main resource. This looks good, but doesn't respect scaleType for the background image: <ImageView android:id="@+id/painting_image" android:layout_width="match_parent" android:layout_height="200dp" android:background="@drawable/img" android:src="@drawable/selector" android:scaleType="centerCrop" /> By the way, @drawable/selector is just a selector that shows a tranparent color for state_pressed: <item android:state_pressed="true"> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#44521400" /> </shape></item> How can I make this work while respecting the scaleType?

  • table row long press

    - by adoo42
    I have a table which is built dynamically based on how much data is present, if at all. I want to be able to long press anywhere on a the table row to be able to get some options to delete or edit etc. Is this possible? Remember I need to do all this without setting any XML as its dynamically built. Is this relevant to what I want to achieve? ` @override public boolean onKeyLongPress(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { // do your stuff here return true; } return super.onKeyLongPress(keyCode, event); } ` any advice is appreciated.

  • PowerPoint API, how to change slide layout programmatically

    - by 112811688864492097861
    Hello, I'm working on PowerPoint Add-In and I was faced with trouble I couldn't solve myself. The point is I need to change the slide Layout programmaticaly with C# (the Add-In Express 2009 for Office and .NET is used). If the new layout is a predefined one everything is fine but I need to set a custom layout as a new one (without slide recreating). Unfortunately, I didn't find any information on how to do it, PowerPoint object model reference documentation didn't answer me as well. There is just the ability to create a new slide that uses custom layout. I've done an experiment seria and have ensured that the Slide object stayed being the same while I have been changing layout both predefined and custom ones. I don't want to create a new slide when I need just switch the layout. Is it possible at all? Please help me to find a way of doing it. Thanks in advance.

  • How to add padding for background image

    - by michael
    Hi, I have a linear layout which has a background image (a 9 patched png file). How can I add padding to left and right so that the background image does not take up the whole width? I have tried 'android:paddingLeft' and 'android:paddingRight', but that does not change anything. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="25dip" android:paddingRight="25dip" android:background="@drawable/background"> The whole background still stretches the whole screen width. Thank you for any help.

    - by kitokid
    I am getting the java.lang.NullPointerException on createTabContent for the following code. There are two tabspecs. When I called and set the tab , changed the tabs for the first time it is ok. But when i called again while I am on the second tab, its hit the null pointer exception for line : NoStudentText.setVisibility(View.VISIBLE); I will show No Student Text if there is no data for the student list. It shows the text for the first time call. But If I do second time call to that tab, got the error. tspecStudent.setContent(new TabContentFactory() { public View createTabContent(String arg0) { if(listStudent != null && listStudent .size() > 0) { //show the student list } else { TextView noStudentText = (TextView)findViewById(R.id.NoStudentText); noStudentText.setVisibility(View.VISIBLE); return noStudentText; } } });

  • Android ListView with SQLite

    - by soclose
    Hi I'd like to refresh the Listview items. These items are populated from SQLite database. My code is below public class Weeve extends Activity { private String[] lv_arr; protected ListView CView; private DBAdapter mDbHelper; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mDbHelper = new DBAdapter(this); mDbHelper.open(); Cursor c = mDbHelper.getAll(); if (c.getCount() > 0) {if (c.moveToFirst()) { ArrayList strings = new ArrayList(); do { String mC = c.getString(0); strings.add(mC); } while (c.moveToNext()); lv_arr = (String[]) strings.toArray(new String[strings.size()]); } } else Toast.makeText(this, "No more Records", Toast.LENGTH_SHORT).show(); c.close(); ListView CView = new ListView(this); CView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, lv_arr)); setContentView(CView);}} I'd like to make refreshing this list view after adding, updating or deleting SQLite table. These operations are called by content or option menu. I tried to create these code into a separated function and call it after every operation. But can't. I think setContentView(CView) statement. I also tried to use SimpleCursorAdapter like notepad sample from Android.com. I got Thread error. Help me.

  • Random pauses with "Key dispatching timed out sending to <null>" when closing Android SurfaceView

    - by kenyee
    When I close an Android SurfaceView Activity, the app sometimes pauses and almost gets an ANR (Application Not Responding) message. Looking at LogCat, it appears to be timing out trying to send keys to it. I tried modifying the code to setFocusable(false) when in the onKeyDown handler for the SurfaceView, but that doesn't seem to affect this. Any other ideas on what might be causing this? Or what these messages in Logcat even mean? ============================= 05-31 19:35:35.285: INFO/WindowManager(586): focus null mToken is null at event dispatch! 05-31 19:35:35.295: WARN/WindowManager(586): Current state: {{KeyEvent{action=1 code=4 repeat=0 meta=0 scancode=158 mFlags=8} to null @ 1275334535292 lw=null lb=null fin=true gfw=true ed=true tts=0 wf=false fp=false mcf=null}} 05-31 19:35:35.305: WARN/WindowManager(586): Continuing to wait for key to be dispatched 05-31 19:35:40.306: WARN/WindowManager(586): Key dispatching timed out sending to 05-31 19:35:40.316: WARN/WindowManager(586): Dispatch state: {{KeyEvent{action=0 code=4 repeat=0 meta=0 scancode=158 mFlags=8} to Window{43763540 com.myapp/com.myapp.DiagramEdit paused=false} @ 1275334499512 lw=Window{43763540 com.myapp/com.myapp.DiagramEdit paused=false} lb=android.os.BinderProxy@43702190 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=null}} 05-31 19:35:40.326: INFO/WindowManager(586): focus null mToken is null at event dispatch! 05-31 19:35:40.326: WARN/WindowManager(586): Current state: {{KeyEvent{action=1 code=4 repeat=0 meta=0 scancode=158 mFlags=8} to null @ 1275334540327 lw=null lb=null fin=true gfw=true ed=true tts=0 wf=false fp=false mcf=null}} 05-31 19:35:40.326: WARN/WindowManager(586): Continuing to wait for key to be dispatched

  • Android: Create spinner programmatically from array

    - by Select0r
    Hi, I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle. Here's what I got: This ArrayList holds the elements that should be in the spinner (gets filled from a file later on): ArrayList<String> spinnerArray = new ArrayList<String>(); This is code I found on a site which should create the spinner: Spinner spinner = new Spinner(this); ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray); spinner.setAdapter(spinnerArrayAdapter); Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ). It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it. Any hint is appreciated. Greetings, Select0r
