    <p>I need to apply some text on the X,Y coordinates of the image where a touch event is occurred. Its just like the Image Tagging on facebook. So every time a touch is occurred, user can put some text in txtview at the touch point.</p> <p>What I've done so far is that I am loading image from gallery and showing it on image viewer.</p> <pre><code>public class LoadImg extends Activity { private static int RESULT_LOAD_IMAGE = 1; int x,y; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); x=0;y=0; String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", ""); if(!picturePath.equals("")) { ImageView imageView = (ImageView) findViewById(R.id.imageView1); imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); } Button buttonLoadImage = (Button) findViewById(R.id.button1); buttonLoadImage.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { Intent i = new Intent( Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i, RESULT_LOAD_IMAGE); } }); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == RESULT_LOAD_IMAGE &amp;&amp; resultCode == RESULT_OK &amp;&amp; null != data) { Uri selectedImage = data.getData(); String[] filePathColumn = { MediaStore.Images.Media.DATA }; Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String picturePath = cursor.getString(columnIndex); PreferenceManager.getDefaultSharedPreferences(this).edit().putString("picturePath", picturePath).commit(); cursor.close(); ImageView imageView = (ImageView) findViewById(R.id.imageView1); imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); } } </code></pre> <p>Also implementing OnTouchListener, I am trying this code but not working. Any help .</p> <pre><code>public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub x=(int) event.getX(); y=(int) event.getY(); imageshow(); return true; } private void imageshow() { // TODO Auto-generated method stub if(x!=0 &amp;&amp; y!=0) { TextView tv=new TextView(this); LinearLayout.LayoutParams trparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); tv.setLayoutParams(trparams); tv.layout(x, y, 0, 0); } } </code></pre> <p>Something like <a href="http://www.thinglink.com/scene/465473253519917057" rel="nofollow">this</a></p>

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.

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