This is an Android learning note about the home key

The question of the proposed

The Android Home Key System is responsible for monitoring and capturing the system to automatically process it. Sometimes, the processing of the system often does not follow our intention, want to deal with the event after clicking Home, then how to do?

Solution to the problem

First prohibit the home button, and then in the onkeydown process key value, click the Home button when the program shut down, or as you xxoo.

@Override Public
      
 boolean onKeyDown (int keycode, keyevent event)  
      
{//TODO auto-generated method stub  
      
  if ( Keyevent.keycode_home==keycode)  
      
    android.os.Process.killProcess (Android.os.Process.myPid ());  
      
     Return Super.onkeydown (KeyCode, event);  
      
  }  
      
       
      
@Override public
      
 void Onattachedtowindow ()  
      
 {//TODO auto-generated the method stub  
      
    This.getwindow (). SetType (WindowManager.LayoutParams.TYPE_KEYGUARD);  
      
    Super.onattachedtowindow ();  
      
 }

Add permission to prohibit home key

<uses-permission android:name= "Android.permission.DISABLE_KEYGUARD" ></uses-permission>
