       new OnTouchListener() { 
        public boolean onTouch(View v, MotionEvent event) { 
         dialog.dismiss(); 
         aboutview(); 
         return true; 
        } 
       }); 
     dialog.show(); 
    } 

我嘗試這一個，不行

@Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     menuplay(); 
     return true; 
    } 

Answer 1

將此用於Menu Button

public boolean onKeyDown(int keyCode, KeyEvent event) { 

if (keyCode == KeyEvent.KEYCODE_MENU && event.getAction() == 0) 
{ 
    menuplay(); 
    return true; 

} 

Answer 2

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 

    getSupportMenuInflater().inflate(R.menu.menu_main, menu); 
    menuplay(); 
    return super.onCreateOptionsMenu(menu); 
}
