    <p>I'm beginner in Android. I have two screens. I am switching between the screens, but <code>onActivityResult()</code> is not called in my application. I'm getting my main screen back. I want result of my second screen.</p> <p>This is my code:</p> <p>mainActivity.java</p> <pre><code>loadPicture.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { Intent i = new Intent(context, ImageThumbnailsActivity.class); startActivityForResult(i, 0); return true; } }); </code></pre> <p>ImageThumbnailActivity.java</p> <pre><code>public class ImageThumbnailsActivity extends Activity { private Cursor imagecursor, actualimagecursor; private int image_column_index, actual_image_column_index; GridView imagegrid; private int count; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.image_gallery); init_phone_image_grid(); } private void init_phone_image_grid() { String[] img = { MediaStore.Images.Thumbnails._ID }; imagecursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null, null, MediaStore.Images.Thumbnails.IMAGE_ID + ""); image_column_index = imagecursor .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID); count = imagecursor.getCount(); imagegrid = (GridView) findViewById(R.id.PhoneImageGrid); imagegrid.setAdapter(new ImageAdapterClass(getApplicationContext())); imagegrid.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { //System.gc(); String[] proj = { MediaStore.Images.Media.DATA }; actualimagecursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, null, null, null); actual_image_column_index = actualimagecursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); actualimagecursor.moveToPosition(position); String i = actualimagecursor.getString(actual_image_column_index); //System.gc(); Intent intent = new Intent(); intent.putExtra("filename", i); //startActivity(intent); setResult(RESULT_OK,intent); finish(); } }); } public class ImageAdapterClass extends BaseAdapter { private Context mContext; public ImageAdapterClass(Context c) { mContext = c; } public int getCount() { return count; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { //System.gc(); ImageView i = new ImageView(mContext.getApplicationContext()); if (convertView == null) { imagecursor.moveToPosition(position); int id = imagecursor.getInt(image_column_index); i.setImageURI(Uri.withAppendedPath( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id)); i.setScaleType(ImageView.ScaleType.CENTER_CROP); i.setLayoutParams(new GridView.LayoutParams(92, 92)); } else { i = (ImageView) convertView; } return i; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
