• Android RadioButton like Behaviour

  - by monxalo

  Greetings, I'm trying to create a single-choice android control, in a horizontal layout, by making use of the RadioGroup behaviour. I can assign the drawable just fine, but i would like to position the label of each RadioButton inside the drawable, is this possible using the standard APIs? <RadioGroup android:id="@+id/switchcontainer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:checkedButton="@+id/RadioButton02" android:padding="3dip"> <RadioButton android:text="id RadioButton02" android:id="@+id/RadioButton02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/radio_button" android:paddingRight="2dip" /> <RadioButton android:text="@+id/RadioButton03" android:id="@+id/RadioButton03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/radio_button" android:paddingRight="2dip" />> </RadioGroup>

• 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).

I can press the menu button on the phone and see the menu items I created, but when I click on the "Settings" (r.id.settings) it FC. Do I have to do anything to the manifest/other thing to get this to work??

• Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

  - by AndyRoid

  I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener. The problem is that when I start the application I get this message: I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder. I also installed Google Play Services APKs through CMD onto my emulator. Furthermore the LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); in my GPSTrack class always returns null. Why is this and how can I fix these issues? Would appreciate an explanation along with solution too, I want to understand what's going on here. ============== Code: gMapFragment.java public class gMapFragment extends SupportMapFragment { private final String TAG = "gMapFragment";

• Sharing a file from Android to Gmail or to Dropbox

  - by Calaf

  To share a simple text file, I started by copying verbatim from FileProvider's manual page: <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.mycorp.helloworldtxtfileprovider.MainActivity" android:exported="false" android:grantUriPermissions="true" > <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/my_paths" /> </provider> <activity android:name="com.mycorp.helloworldtxtfileprovider.MainActivity" ... Then I saved a text file and used, again nearly verbatim, the code under Sending binary content. (Notice that this applies more accurately in this case than "Sending text content" since we are sending a file, which happens to be a text file, rather than just a string of text.) For the convenience of duplication on your side, and since the code is in any case so brief, I'm including it here in full. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String filename = "hellow.txt"; String fileContents = "Hello, World!\n"; byte[] bytes = fileContents.getBytes(); FileOutputStream fos = null; try { fos = this.openFileOutput(filename, MODE_PRIVATE); fos.write(bytes); } catch (IOException e) { e.printStackTrace(); } finally { try { fos.close(); } catch (IOException e) { e.printStackTrace(); } } File file = new File(filename); Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); shareIntent.setType("application/txt"); startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to))); file.delete(); } } Aside from adding a value for send_to in res/values/strings.xml, the only other change I did to the generic Hello, World that Eclipse creates is to add the following in res/xml/my_paths.xml (as described on the page previously referenced. <paths xmlns:android="http://schemas.android.com/apk/res/android"> <Files-path name="files" path="." /> </paths> This code runs fine. It shows a list of intent recipients. But sending the text file to either Dropbox or to Gmail fails. Dropbox sends the notification "Uploading to Dropbox" followed by "Upload failed: my_file.txt". After "sending message.." Gmail sends "Couldn't send attachment". What is wrong?

• Android, FragmentActivity and prevent Swipe

  - by FIG-GHD742

  I use android.support.v4.app.FragmentActivity for create a app with multi fragment/panels that can be access by drag/swipe between different part of the app. In one of my fragment I has a zoomable view and my problem is in case I is on the zoomable view I will prevent the use for drag/swipe to a other fragment. I has try to hack into android.support.v4.view.ViewPager for get the action from on Touch event but not work. I has try all of this case but not work: (All code is a a part of subclass to android.support.v4.view.ViewPager) Case 1: // Not working @Override protected void onPageScrolled(int position, float offset, int offsetPixels) { if (isPreventDrag()) { super.onPageScrolled(position, 1, 0); } else { super.onPageScrolled(position, offset, offsetPixels); } } Case 2: // Work but stop all event include the event to the target image view. @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: lastX = ev.getX(); // float lockScroll = false; return super.onInterceptTouchEvent(ev); case MotionEvent.ACTION_MOVE: this.lockScroll = this.isPreventDrag(); break; } if (lockScroll) { ev.setLocation(lastX, ev.getY()); return super.onInterceptTouchEvent(ev); } else { return super.onInterceptTouchEvent(ev); } } Case 3: // Work good, but by some unknown error I can drag the screen // some pixels before this stop the event. @Override public boolean onTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return true; } else { return super.onTouchEvent(ev); } } I want a easy way to deactivate stop or deactivate if the use is allow to switch to a other Fragment. Here is a working code for me, I don't know what error I do before. // This work for me, @Override public boolean onInterceptTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return false; } else { return super.onInterceptTouchEvent(ev); } }

• Newbie question: How do you layout an icon, 2 text lines and a button?

  - by Keith Barrows

  I am trying to extend a sample I found at http://developer.android.com/resources/articles/layout-tricks-efficiency.html. I am a brand new MonoDroid developer, just installed it yesterday, and trying to jump right into UI design and so far it is not clicking for me completely. I have this main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="200dip" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Second line which is a long line of text and needs to scroll" /> <TextView android:id="@+id/firstLine" android:layout_width="200dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" android:text="First line" /> <Button android:id="@+id/logonButton" android:layout_width="50dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/secondLine" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:gravity="center_vertical" android:text="Login" /> /> </RelativeLayout> What I am trying to do is have an icon on the left, 2 lines of text stacked in the middle and a button on the right. When I run this in my emulator I am seeing: The second line is not scrolling. The button does not show up. Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine. Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)

• Wrapping Arbitrary XML within XML

  - by Marc C

  I need to embed arbitrary (syntactically valid) XML documents within a wrapper XML document. The embedded documents are to be regarded as mere text, they do not need to be parseable when parsing the wrapper document. I know about the "CDATA trick", but I can't use that if the inner XML document itself contains a CDATA segment, and I need to be able to embed any valid XML document. Any advice on accomplishing this--or working around the CDATA limitation--would be appreciated.

• Unable to Start Activity ComponentInfo when Starting a New Activity

  - by Timtim17

  {I know there's already a whole bunch of questions like this, but I can't see any problems that related to my program.} I have an Android App that is supposed to take a name from a EditText and put it in a TextView in another activity. It previously worked, but then I wanted it to start another activity if the EditText's value was equal to "ANDROID". However, now the app crashes whenever I try to start either activity. First Activity: package net.timtim17.dev.android.fun.nametag; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.view.View; import android.view.View.OnClickListener;

setContentView(R.layout.activity_main); final EditText et = (EditText) findViewById(R.id.editText1); Button submit = (Button) findViewById(R.id.button1); submit.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { String text = et.getText().toString(); if(text.equals("ANDROID")){ Intent android = new Intent(MainActivity.this, AndroidNameTag.class); startActivity(android); }else{ Intent intent = new Intent(MainActivity.this, NameTag.class); intent.putExtra("name", text); startActivity(intent); } } }); } } NameTag Activity: package net.timtim17.dev.android.fun.nametag; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class NameTag extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

• Nested Linear layout only shows first view after being set from gone to visible in Android

  - by Adam

  Hi guys, I am developing an Android app but I'm still pretty new. I want to have a button, and when you push that button, a few TextViews and Buttons will appear. So I have a main linear layout, and then another linear layout nested inside containing the things I want hidden. I have the nested linear layout set to android:visibility="gone". The problem I am having is that it only shows the first item inside the hidden linear layout instead of all of them. The way I try to make it appear is vgAddView = (ViewGroup)findViewById(R.id.add_details); btnAche.setOnClickListener(new OnClickListener(){ public void onClick(View v){ vgAddView.setVisibility(0); } }); My XML file is this <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:text="@string/but_stomach_ache" android:id="@+id/but_stomach_ache" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <Button android:text="@string/but_food" android:id="@+id/but_food" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/add_details" android:visibility="gone"> <TextView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/when_happen"> </TextView> <Button android:text="@string/happen_now" android:id="@+id/happen_now" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> </LinearLayout> </LinearLayout>

• How do you set Android ViewPager to encompass only one View or Layout?

  - by Kyle

  I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

• XML Parsing from Non-XML Document

  - by Neel Basu

  in a xml/non-xml File there may exist some XML Block that I need to parse and replace with some other string.. The Scenario is something like this.. Some Text <cnt:use name="abc" call="xyz"> <cnt:param name="x" value="2" /> </cnt:use> Some Text There is no guarantee that the document is a proper XML document. (there may exist some unclosed Tags. or some other common mistakes that a Stupid people can make while typing HTML). so I can't use SAX or DOM. I can't even pass it to XSLT (am I right ?). So Whats the best way to extract the <cnt:*> part from the non-xml Document. and read it then replace with something else.

• How to transport an XML fragment in an XML Document

  - by mrwayne

  Hi, I'm using an AJAX system on a web application, and for one of the objects i return, it needs to contain an xml fragment. Unfortunately, being AJAX, i'm sending the values back via XML already. So, at the moment, i have something that looks like this (ignoring the fact the tags arent perfect. <Transport> <Message> <Content><[CDATA...] XML Content in here </Cdata></Content> </Message> </Transport> This has worked pretty well for the last few years, however, now the XML content itself needs to contain its own CDATA tags and its causing me grief because you cannot nest CDATA sections. Is there another way to encode the 'XML Content' internally?

I could not figure out how to do this using the standard validation approach in Java: SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); Schema schema = schemaFactory.newSchema(... /* the .xsd source */); Validator validator = schema.newValidator(); DocumentBuilderFactory ... DocumentBuilder ... Document document = DocumentBuilder.parse(... /* the .xml source */); try { validator.validate(new DOMSource(document)); ... } catch (SAXParseException e) { ... } I have toyed with the idea of getting at least the line and column number from SAXParseException, but they're always set to -1, -1 on validation error.
