  • "No XML content. Please add a root view or layout to your document."

    - by ez4nick
    I am trying to follow this tutorial : http://developer.android.com/training/basics/firstapp/building-ui.html as I am new to android developing and this is what my "activity_main.xml" file looks like : <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal"> <EditText android:id="@+id/edit_message" android:layout_weight="1" android:layout_width="0dp" android:layout_height="wrap_content" android:hint="@string/edit_message" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send" /> When I click run I get an error that says "No XML content.

  • How can I specify a dynamic height for an ImageView?

    - by kefs
    I have an ImageView at the top of my display that looks like the following: +----------------------------------------------+ ¦ ImageView +--------------+ ¦ ¦ ¦ ¦ ¦ ¦ ¦ Actual image ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ +--------------+ ¦ +----------------------------------------------+ Below this, I have a series of Buttons and TextViews.. I would like the ImageView's height to dynamically increase depending on the max height of the screen. I'm aligning the layout containing the buttons along the bottom of edge of the screen, and I would like the rest of the screen taken up by the above ImageView. Also, since the ImageView contains a centered image, I would also like to set min height, and a scrollbar if the screen is too small to display the imageview and the buttons below. Thanks! Is this possible?

  • When I debug my application I get frequently Launch error: Failed to connect to remote VM

    - by Pentium10
    When I debug my application I get frequently Launch error: Failed to connect to remote VM even If I try again it doesn't help, I need to restart Eclipse. Edit Not sure yet fully if the symptoms have to do with the fact that I get this error only when I launch Debug without a code modification. Whenever I do a modification to the source code and hit Debug it goes through, but if I don't it doesn't.

  • EGL initialized failed

    - by aquatear
    Hello Everybody, I used a SurfaceView and EGL to render my 3D contents. When I press BACK and return my activity, the activity's 3D objects become to white. The reason is when the original activity(3D activity) resume, EGL would initialize again. So EGL would initialize and destroy everytime when different activities switch. I am not sure if the problem is EGL initialize twice... but I did initialize and destroy EGL correctly. Anybody have this problem ? Have any solutions about this ?? Thank you so much

  • Is it possible to start an activity from a regular java class?

    - by Yotam
    In my ActionBarSherlock I have the same menu items for all activities, so it seems unwise to define onClick handlers in each activity - they all do the same. Instead I created a class called MyClickListener that implements com.actionbarsherlock.view.MenuItem.OnMenuItemClickListener, and in there I have a simple switch block that starts the appropriate activity. Problem is that Intent constructor's first argument is of type Context, and even when I pass this to MyClickListener's constructor, I can't start any activity. The same goes for every method that has a Context object as a parameter. Is there a way to work around it? What is a context object? Thanks

  • Emulating Preference look/feel with LinearLayout

    - by colinodell
    I really like the look and feel of the Preference UI items and want to replicate that in my application. Basically I've got an Activity with a couple LinearLayouts set to be focusable. When they are focused, I want them to turn green (like Preferences do). Any idea how to apply that style to my LinearLayouts? Note: The LinearLayouts are essentially going to be clickable 'buttons' to launch a separate activity. They are NOT actual preferences or buttons, although they need to look/act similar to them.)

  • ListSelector applies to the entire list

    - by jax
    I have a simple list with a listselector like so. <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@+id/round" android:listSelector="#99000000" android:clickable="true" android:cacheColorHint="#00000000" android:background="#00000000"> </ListView> As you can see android:listSelector="#99000000" but the "black alpha" color is applied to the entire list, not the selected item. So this is what I have now but the entire list still turns black ::listview_background.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:state_focused="true" android:drawable="@drawable/list_normal" /> <item android:state_pressed="true" android:drawable="@drawable/list_pressed" /> <item android:state_focused="true" android:drawable="@drawable/list_active" /> </selector> ::colors.xml <resources> <drawable name="list_normal">#96FFFFFF</drawable> <drawable name="list_active">#66000000</drawable> <drawable name="list_pressed">#CA000000</drawable> </resources> ::the xml tag in my list android:listSelector="@drawable/listview_background"

  • 3d cube using canvas. Need a little improvement

    - by TimeManx
    I made this 3d cube using the following code Matrix mMatrix = canvas.getMatrix(); canvas.save(); camera.save(); camera.rotateY(-angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp1, 0, 0, null); camera.restore(); canvas.restore(); camera.rotateY(90 - angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width2, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp2, width, 0, null); This is what it gives But what I need is It's because when Camera rotates the images, some part of the image gets hidden. Like this But I think this can be done.

  • ListView getting deleted onbackpress

    - by adohertyd
    I have a listview in my mainactivity that makes a call to a database to populate it. When an item on the listview is clicked it starts a new activity showing the details of the item that was clicked. When the back button is pressed the listview is not displayed again. What could be the problem? This is the entirety of my mainactivity: public class MainActivity extends ListActivity { Button bAddMod; private ModuleDB db; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); db = new ModuleDB(this); db.open(); fillList(); db.close(); bAddMod = (Button) findViewById(R.id.btnAddMod); bAddMod.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent i = new Intent(MainActivity.this, AddModule.class); startActivity(i); } }); } private void fillList() { ListView lv = getListView(); Cursor curs = db.getData(); startManagingCursor(curs); MyCursorAdapter adapter = new MyCursorAdapter(getApplicationContext(), curs); lv.setAdapter(adapter); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id){ Intent k = new Intent(MainActivity.this, ModuleDetails.class); k.putExtra("mod_id", id); startActivity(k); } }); } }

  • finditem() doesn't find menu, stuck with NullPointerException

    - by fdansv
    I'm stuck while changing some properties on my options menu at onCreateOptionsMenu(). It seems like findItem() returns null, even though I'm pretty sure that the reference to the menu item is correct. My code looks as follows: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_profile, menu); MenuItem leftie = menu.findItem(R.id.menu_profile); leftie.setIcon(R.drawable.ic_menu_mapmode); leftie.setTitle(R.string.back_map); leftie.setIntent(authIntent); return true; } I really don't know what can be wrong there. Thanks in advance :) EDIT: I forgot to include the actual problem.

  • TextAppearance_Holo_Large - No resource found

    - by npmaster
    When compiling my app I get the following error: android-apt-compiler: ... \res\values-v14\styles.xml:12: error: Error retrieving parent for item: No resource found that matches the given name '@android:style/TextAppearance_Holo_Large. The code it is complaining about is: <style name="Title" parent="@android:style/TextAppearance_Holo_Large"> <item name="android:layout_height">wrap_content</item> <item name="android:layout_width">wrap_content</item> </style> I checked my manifest file and I have set the SDK to: <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="17" /> Which i believe allows for using the Holo Themes. I am using Android Studio though I doubt that is the cause of the error. Any ideas what I am doing wrong?

  • Can't referr to my get method

    - by chility
    I have this amazing and good looking class: public class SayingsHolder extends Application{ ArrayList<String> SayingsList = new ArrayList<String>(){{ SayingsList.add("1"); SayingsList.add("2"); }}; public ArrayList<String> getSayingsList() { return SayingsList; } } Now I'm trying to call the getSayingsList method inside of my activity's FragmentStatePagerAdapter by: private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { final SayingsHolder holder = (SayingsHolder).getApplication(); } Everything fine for now, but when I make my code like this: private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { final SayingsHolder holder = (SayingsHolder).getApplication(); holder.getSayingsList(); } it says: Syntax error on token "getSayingsList", Identifier expected after this token The problem is that holder is not functional at all. What I mean is that when i type the this holder. the getSayingsList is not showing at all. What am I missing here? I know that it is an extremely small issue, but it seems that I can't spot it. My activity extends FragmentActivity if it's important It seems that I'm missing something here. I can't call my method anywhere in my activity. I'm starting a bounty, because I need an example.

  • Including different code for other home screen replacement screens

    - by radicam2
    I have put together a Skin for OpenHome but have since ran across AHome code for their IPhone theme and was wondering that if I included for AHome their Dock_Bg or widget_drawer among other things which is not on OpenHome that the Launcher for the respective screen replacement would just call the items it uses.I want to keep the mb as low as I can but reach more handsets.I can just make seperate ones but see many that include even Freshface as well as OpenHome and AHome.

  • wifi provider onLocationChanged is never called

    - by Kelsie
    I got a weird problem. I uses wifi to retrieve user location. I have tested on several phones; on some of them, I could never get a location update. it seemed that the method onLocationChanged is never called. My code is attached below.. Any suggestions appreciated!!! @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager locationManager; locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); String provider = locationManager.NETWORK_PROVIDER; Location l = locationManager.getLastKnownLocation(provider); updateWithNewLocation(l); locationManager.requestLocationUpdates(provider, 0, 0, locationListener); } private void updateWithNewLocation(Location location) { TextView myLocationText; myLocationText = (TextView)findViewById(R.id.myLocationText); String latLongString = "No location found"; if (location != null) { double lat = location.getLatitude(); double lng = location.getLongitude(); latLongString = "Lat:" + lat + "\nLong:" + lng; } myLocationText.setText("Your Current Position is:\n" + latLongString); } private final LocationListener locationListener = new LocationListener() { public void onLocationChanged(Location location) { updateWithNewLocation(location); Log.i("onLocationChanged", "onLocationChanged"); Toast.makeText(getApplicationContext(), "location changed", Toast.LENGTH_SHORT).show(); } public void onProviderDisabled(String provider) {} public void onProviderEnabled(String provider) {} public void onStatusChanged(String provider, int status, Bundle extras) {} }; Manifest <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.INTERNET"/>

  • How do I handle the browser's "share page" intent in android?

    - by gfxmonk
    I read here ( http://androidlittle.blogspot.com/2009/08/intent-filter-for-share-link.html ) what intent-filter is required to handle the "share link" intent that the android web browser sends. I have placed this inside an block in my AndroidManifest.xml like so: <activity android:name=".ShareLink"> <intent-filter> <action android:name="android.intent.action.SEND" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="text/plain" /> </intent-filter> <meta-data/> </activity> I cannot for the life of me get this to be triggered though. When I share a link in the android browser, the emulator log shows it's creating a chooser intent, but doesn't give the details of the intent the chooser is acting on. No chooser window pops up, and the intent gets handled by the SMS application. I have also tried kicking off the intent manually: adb shell am start -D -a android.intent.action.SEND -c android.intent.category.DEFAULT -t text/plain -d http://google.com/ but the response I get is: Starting: Intent { act=android.intent.action.SEND cat=[android.intent.category.DEFAULT] dat=http://google.com/ typ=text/plain } Error: Activity not started, unable to resolve Intent { act=android.intent.action.SEND cat=[android.intent.category.DEFAULT] dat=http://google.com/ typ=text/plain flg=0x10000000 } Can anyone tell me what I'm doing wrong? My main (launcher) activity works fine, so I assume there is no issue with installation on the emulator.

  • The application has stopped unexpectedly: How to Debug?

    - by Android Eve
    Please note, unlike many other questions having the subject title "application has stopped unexpectedly", I am not asking for troubleshooting a particular problem. Rather, I am asking for an outline of the best strategy for an Android/Eclipse/Java rookie to tackle this formidable task of digesting huge amounts of information in order to develop (and debug!) a simple Android application. In my case, I took the sample skeleton app from the SDK, modified it slightly and what did I get the moment I try to run it? The application (process.com.example.android.skeletonapp) has stopped unexpectedly. Please try again. OK, so I know that I have to look LogCat. It's full of timestamped lines staring at me... What do I do now? What do I need to look for? Is there a way to single-step the program, to find the statement that makes the app crash? (I thought Java programs never crash, but apparently I was mistaken) How do I place a breakpoint? Can you recommend an Android debug tutorial online, other than this one?

  • Netflix Updates Android Tablet App; iPad Update On The Way

    - by Jason Fitzpatrick
    Android: If you’re rocking an Android tablet, such as a Kindle Fire or Nook, you’ll want to update your Netflix app today. The new version sports a host of improvements including a massively overhauled interface. The old Netflix tablet application was functional but lackluster; it felt almost as if they didn’t realize they were designing it for a tablet. The new Netflix app is focused on beautiful cover-flow style navigation, displaying twice as many titles per screen, and an emphasis on natural navigation with finger swipes and taps. According to the Netflix press release, an iPad update will be rolling out in the next few weeks.

  • How to set up an environment for android app development?

    - by The Dark Knight
    I have been researching for sometime now regarding the process to install android sdk and associated tools . After visiting Android Developers page, i first installed the android sdk and then installed eclipse plugins for my indigo version from the install softwares options.However, it is mentioned in the developers page : Download the Android SDK. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE). Download the latest SDK tools and platforms using the SDK Manager. I have downloaded the sdk and installed the adt plugins for eclipse.I just need to point the eclipse towards the location of the sdk. However, i am stuck at the last step which is asking me to download the latest tools using the sdk manager. The manager interface pops up and i see a lot of options there. I don't know which ones i must select and install. If some one can help me out here and tell me which options to choose and install(if possible, with a screen shot), it will be very beneficial for me.
