How to stop displaying message from Toast when Application is closed?

Question

This is my sample code:

    Button buttonClick;
    @Override
    protected void onCreate(Bundle savedInstanceS         


        

Answer 1

Try this,

You can cancel Toast showing using this code.

  final Toast toast = Toast.makeText(getApplicationContext(), "This message will    disappear     in half second", Toast.LENGTH_SHORT);
toast.show();

Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
       @Override
       public void run() {
           toast.cancel(); 
       }
}, 500);

Answer 2

Try to use finish() in your OnCreate() function on some condition. Hope this will help you.

You probably want to cancel the Toast whenever your app is not visible, so I would cancel it on the method 'onStop()'.

Here it goes:

public class MainActivity extends Activity {
    private Toast toast = null;
    Button buttonClick;

    @SuppressLint("ShowToast")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toast = Toast.makeText(getApplicationContext(), "", Toast.LENGTH_LONG);
        buttonClick = (Button) findViewById(R.id.buttonClick);
        buttonClick.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                toast.setText("My toast!");
                toast.show();
            }
        });
    }

    @Override
    protected void onStop () {
        super.onStop();
        toast.cancel();
    }

}

Edit: Updated, it should work as OP intended now.

Answer 4

I want if the application is closed then Toast should also stop displaying the message.

In your case call cancel() to Toast object to cancel it within onDestroy() method.

Here is a similar example.

Updated!

I tested OP solution but no result.

.hide() and .cancel() method is available for Toast but seem they are not working. The solution is, you have to create your own custom view which acts like a Toast and then you can cancel all Toasts when the Activity finishes.

Answer 5

Store a reference to your toast object. In your onDestroy, if the toast is not null then call cancel() on it.
