Android's solution for repeated display of Toast is androidtoast.

Solution:You do not need to calculate the Toast time or the like, that is, to define a global member variable Toast. make is used only when Toast is not null; otherwise, setText is used directly. to immediately disable Toast display after you press the return key, rewrite the onBackPressed () method of the parent Activity to cancel your Toast.

 

Code:

Private Toast mToast; public void showToast (String text) {if (mToast = null) {mToast = Toast. makeText (TestActivity. this, text, Toast. LENGTH_SHORT);} else {mToast. setText (text); mToast. setDuration (Toast. LENGTH_SHORT);} mToast. show ();} public void cancelToast () {if (mToast! = Null) {mToast. cancel () ;}} public void onBackPressed () {cancelToast (); super. onBackPressed ();}
