Animation Doesn't Work

Question

Intent intent = null; intent = new Intent(this, A.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NEW_TASK); overridePendingTransition(R.anim.no_animation, R.anim.slide_down_out); ClassSelector.this.finish(); startActivity(intent); 

I need to go from the current page to another page, that is A. I added the code 'intent.addFlags (Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);' since this code applies, the animation that applies to A does not work.

Answer 1

two flags

 Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NEW_TASK 

have the opposite intention. One brings the old activity from above, and the other creates a new task that may have results that cannot be predicted.

 Intent.FLAG_ACTIVITY_SINGLE_TOP 

which can bring you the necessary animation.

Answer 2

You can call finish() in your activity right after calling startActivity() (and get rid of your flags), and then in this new action in the onBackPressed() method call this code:

 @Override public void onBackPressed() { Intent intent = new Intent(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_HOME); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); } 

Answer 3

You just need to place an overridePendingTransition call after startActivity.

Example:

  Intent intent = null; intent = new Intent(this, A.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NEW_TASK); ClassSelector.this.finish(); startActivity(intent); overridePendingTransition(R.anim.no_animation, R.anim.slide_down_out);
