How to display transparent activity on the another activity without removing previous activity ?

I am able to create transparent activity but when i trying to push i

Answer 1

declare your activity in manifest like this

and add a transperent background to your layout like this

Edit:

i think you are using this to open your transparent activity it finish your previous activity

Intent intent =new Intent(mContext,yourNewActivity.class);
startActivity(intent);
finish();

remove finish from here then your new activity in on top of previous activity like this

 Intent intent =new Intent(mContext,yourNewActivity.class);
 startActivity(intent);
