Animation not working

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 have a transition from current page to another page that is A. i have added code 'intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NEW_TASK);' since this code is applied animation that is applied for A is nor working.

Answer 1

the two flags

Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NEW_TASK

have opposite intention. One brings the old activity on top and the other creates a new task which could have results that cannot be predicted.

Intent.FLAG_ACTIVITY_SINGLE_TOP

which could bring the animation you need.
