Question

I have make application in which swipe Gesture detection is used for left to right & right to left.
I got success with 2.2 AVD emulator, but when I try to use same code in tablet 3.0 it not working

Please tell me whats wrong.

private static final int SWIPE_MIN_DISTANCE = 120;
    private static final int SWIPE_THRESHOLD_VELOCITY = 200;
   private class GestureListener extends SimpleOnGestureListener {
        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
                float velocityY) {
            if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                    && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {

                Toast.makeText(RssActivity.this, "Right to left",
                        Toast.LENGTH_LONG).show();
                SetNewRightclickActivity();
                Log.i(TAG, "Right to left");
                return true; // Right to left

            } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                    && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {

                Toast.makeText(RssActivity.this, "Left to right",
                        Toast.LENGTH_LONG).show();
                Log.i(TAG, "Left to right");
                SetNewLeftclickActivity();
                return true; // Left to right

            }
            if (e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE
                    && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {

                return true; // Bottom to top
            } else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE
                    && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {

                return true; // Top to bottom
            }
            return false;
        }
    }

Main::

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.rssheader);

        gestureDetector = new GestureDetector(new GestureListener());
        gestureListener = new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                return gestureDetector.onTouchEvent(event);
            }
        };

You need to set gestureListener (in onCreate method) to a view on which you want to detect swipes.

Set id to a view/viewgroup in your layout in rssheader.xml, for example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:id="@+id/myLayout"
    android:clickable="true">

</LinearLayout>

now fetch that id in Activity class and set listener to it

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.rssheader);

    LinearLayout ll = (LinearLayout) findViewById(R.id.myLayout);

    GestureDetector gestureDetector = new GestureDetector(new GestureListener());
    OnTouchListener gestureListener = new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            return gestureDetector.onTouchEvent(event);
        }
    };

    ll.setOnTouchListener(gestureListener);

}
