    <p>I'm trying to add "fling" gesture detection in simple gesture recognition source code that developer has(<a href="http://android-developers.blogspot.com/2009/10/gestures-on-android-16.html" rel="nofollow">on this site</a>). and this is the code:</p> <pre><code>public class GestureMix extends Activity implements OnGesturePerformedListener{ /** Called when the activity is first created. */ private GestureLibrary mLibrary; private static final int LARGE_MOVE= 60; private static final String TAG= "Debug"; private GestureDetector gestureDetector; TextView tv; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); tv= (TextView)findViewById(R.id.textView1); gestureDetector= new GestureDetector(this, new SimpleOnGestureListener(){ @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY){ if(e1.getY()- e2.getY() &gt; LARGE_MOVE){ tv.setText("\nFling Ke Atas dengan kecepatan" +velocityY); //tv.append("\nFling Ke Atas dengan kecepatan" +velocityY); Log.d(TAG, "\nFling Ke Atas dengan kecepatan" +velocityY); return true; } else if(e2.getY()-e1.getY() &gt; LARGE_MOVE){ tv.setText("\nFling Ke Bawah dengan kecepatan" +velocityY); //tv.append("\nFling Ke Bawah dengan kecepatan" +velocityY); Log.d(TAG,"\nFling Ke Bawah dengan kecepatan" +velocityY ); return true; } else if(e1.getX()-e2.getX() &gt; LARGE_MOVE){ tv.setText("\nFling Ke Kiri dengan kecepatan" +velocityX); //tv.append("\nFling Ke Kiri dengan kecepatan" +velocityX); Log.d(TAG, "\nFling Ke Kiri dengan kecepatan" +velocityX); return true; } else if(e2.getX()-e1.getX() &gt; LARGE_MOVE){ tv.setText("\nFling Ke Kanan dengan kecepatan" +velocityX); //tv.append("\nFling Ke Kanan dengan kecepatan" +velocityX); Log.d(TAG,"\nFling Ke Kanan dengan kecepatan" +velocityX ); return true; } return false; } }); Log.d(TAG, "d on create"); mLibrary= GestureLibraries.fromRawResource(this, R.raw.gestures); if(!mLibrary.load()){ finish(); } GestureOverlayView gst= (GestureOverlayView) findViewById(R.id.gesture); gst.addOnGesturePerformedListener(this); } @Override public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { // TODO Auto-generated method stub Log.d(TAG, "d gesture perform"); ArrayList&lt;Prediction&gt; predictions= mLibrary.recognize(gesture); if(predictions.size()&gt;0){ Prediction prediction= predictions.get(0); if(prediction.score &gt;1.0){ Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show(); Log.d(TAG, prediction.name); } } } @Override public boolean onTouchEvent(MotionEvent event){ Log.d(TAG, "d on touch"); return gestureDetector.onTouchEvent(event); } </code></pre> <p>}</p> <p>The gesture recognition went well (it toast the right result), but the gesture detection (onfling) won't show the result (it won't appear whether in the textview or in the logCat. It seems the gesture detector won't work on <strong>gestureoverlayview</strong>.</p> <p>How could I fix this code, so I could see the gesture recognition and the velocity of the fling as the result?</p> <p>Any advice would be greatly appreciated. Please ask for clarification and I'll happily tell you the specifics of what I've tried.</p> <p>I'm sorry for my bad in English and less knowledge in programming. Thanks.</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.
