Modify onFling() of MyGestureListener of MainActivity.java in last post, to call overridePendingTransition() after startActivity().
@Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
/*
Toast.makeText(getBaseContext(),
event1.toString() + "\n\n" +event2.toString(),
Toast.LENGTH_SHORT).show();
*/
if(event2.getX() < event1.getX()){
Toast.makeText(getBaseContext(),
"Swipe left - startActivity()",
Toast.LENGTH_SHORT).show();
//switch another activity
Intent intent = new Intent(
MainActivity.this, SecondActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.slide_left_in, R.anim.slide_left_out);
}
return true;
}
Modify onFling() of My2ndGestureListener of SecondActivity.java in last post, to call overridePendingTransition() after finish().
@Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
/*
Toast.makeText(getBaseContext(),
event1.toString() + "\n\n" +event2.toString(),
Toast.LENGTH_SHORT).show();
*/
if(event2.getX() > event1.getX()){
Toast.makeText(getBaseContext(),
"Swipe right - finish()",
Toast.LENGTH_SHORT).show();
finish();
overridePendingTransition(R.anim.slide_right_in, R.anim.slide_right_out);
}
return true;
}
For /res/layout/activity_main.xml and AndroidManifest.xml refer to last post.
Download the files.

I found this excellent tutorial and have started to put it to use.
I have a question about the slide transition.
When swiping to the left, the 2nd activity enters smoothly and everything is great.
When swiping right, the 2nd activity enters the screen and then flashes to the main activity.
How can I set it so that it previews the mainactivity content
I had the same problem
Help please ;(
I exchanged 'slide_right_in' for 'slide_right_out' and vice versa on SecondActivity and it now works correctly :)
