View 1 Replies View RelatedAndroid :: View Image In Action View Intent?
Nov 16, 2009I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.
Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);
I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?

I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.

View 2 Replies View RelatedAndroid :: List View On Item Click Listener Not Working
Sep 6, 2010What I´m trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. I´ve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the item´s view but it still doesn´t work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

View 2 Replies View RelatedAndroid :: Apply Animation To View In Application After Created Activity?
Sep 23, 2010I am trying to apply an animation to a view in my Android app after my activity is created. To do this, I need to determine the current size of the view, and then set up an animation to scale from the current size to the new size. This part must be done at runtime, since the view scales to different sizes depending on input from the user. My layout is defined in XML. This seems like an easy task, and there are lots of SO questions regarding this though none which solved my problem, obviously. So perhaps I am missing something obvious. I get a handle to my view by: ImageView myView = (ImageView)getWindow().findViewById(R.id.MyViewID);
This works fine, but when calling getWidth(), getHeight(), getMeasuredWidth(), getLayoutParams().width, etc., they all return 0. I have also tried manually calling measure() on the view followed by a call to getMeasuredWidth(), but that has no effect. I have tried calling these methods and inspecting the object in the debugger in my activity's onCreate() and in onPostCreate(). How can I figure out the exact dimensions of this view at runtime?
Android :: List View Context Menu And OnItem Click Listener Not Working
Sep 9, 2010I have a tab activity with three tabs and I want to display a listview in each tab. The list populates correctly, but for some reason I can not get the context menu or itemclicklistener to recognize gestures on the listviews. Anyone have any ideas why this might be? Below is my onCreate method: @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstanceState);setContentView (R.layout.armory_header); TabHost mTabHost = getTabHost(); mTabHost.addTab (mTabHost. newTabSpec ("1"). setIndicator ("Weapons"). setContent (R.id.page1)); mTabHost.addTab (mTabHost.newTabSpec("2").setIndicator( "Armor" ).setContent(R.id.page2))TabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories"). setContent (R.id.page3)) ; weapons = (ListView) findViewById(R.id.weaponlist); registerFor ContextMenu(weapons) ;weapons.setOn ItemClickListener (new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {// TODO Auto-generated method stub listId = weapons.getId(); position = arg2; showDialog (DIALOG);armor = (ListView) findViewById (R.id.armorlist) ;register ForContext Menu(armor); armor.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItem Click(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub listId = armor.getId();position = arg2; showDialog(DIALOG);
View 2 Replies View RelatedAndroid : Close Current Activity When An Action Happens In Custom View
Oct 13, 2010I have a toolbar view set for most of my activities.
The toolbar has several buttons which all trigger certain intents. Now, the problem is: how can I close current activity before starting another one ?
Problem 1) Activity cones For instance one of the buttons ('A') starts activity A. Activity A also has toolbar. If you press on the 'A' button, a new A activity will be started. I suppose I can look at Activity.getInstanceCount(), right ?
Problem 2) Unnecessary activities The activity X is not needed any more if the opts for A. I just want A then. How can I remove X from toolbar which only has access to context ?
I, of course could find toolbar view inside activity X and override the onClicks, but in general this would mean doing so for all my activities !? Am I on the right track ?
Android : Wire A Button Action Without Activity Implementing View.OnClickListener
May 11, 2010I'm starting with Scala + Android (and using the sbt android plugin). I'm trying to wire a button action to a button without the activity implementing View.OnClickListener.
