android listview view listadapter greendroid
I’m trying to create a bitmap out of ListView items. I am using the Greendroid library (if that makes any difference). I initially had this working for lists where # of items is < 7 (since you can only see 6 items on the screen). I am now trying to build each view item individually, before getting the drawing cache. In the code bellow, I get a null pointer exception at childView.buildDrawingCache(). Am I calling getView() correctly? Are there any other simple solutions to this problem?try {B

My app has a static DB which I need to update with new content. The schema won’t change. I’ve put the DB into assets/ and when the app launches it, it copies the DB (in the SQLiteOpenHelper constructor) into the application’s databases/ directory. The copy code is as follows:private void importAssets(boolean overWrite) throws IOException {AssetManager am = mCtx.getAssets();InputStream in = am.open(DB_NAME);FileOutputStream out;byte[] buffer = new byte[1024];int len;File dir, db;dir = new File(DB

But all I get in return is a ClassCastException telling me nothing about its specific cause.First about the Application I want to develop:I want to create an Hex View (and later an Hex-Editor) for Android enabled devices. The ListAdapter was business as usual and works flawlessly. The SectionIndexer part however does not. I want to enable the user to scroll through large f

I have created a main.xml layout with both a mapview and listview in FrameLayout, extended the MapView class,

Apologies if this has been asked/answered before – please link it to me. I have searched up and down but find other unrelated (to me at least) problems.The real puzzler for me is that my app is crashing on my emulator but when installed on my phone (via upload of apk to phone and then using an AppInstaller app from market) it works.The crash comes from a NullPointer

An OnItemClickListener for a ListView has the following method:@Override public void onItemClick(AdapterView<?> parent, View v, int position, long id)I’d like to have the adapter behind the ListView refresh, and I believe this is done through the use of:BaseAdapter.notifyDataSetChanged()How do I use the parent parameter in the onItemClick method to do this? So far I’ve tried:parent.getAdapter().notifyDataSetChanged();This throws an error because the object returned is of class HeaderViewLi
