Android program to achieve home key shielding, capture and modify the method _android

This article describes the Android program to achieve the home key shielding, capture and modify the method. Share to everyone for your reference, specific as follows:

Personal supplement: This method needs to add the permission, and after the modification intercepts the home key, therefore recommends cautiously uses ~

The development process I believe that we have encountered because can not capture the home key and worry, now finally have a way, in Level5 above (included), the activity class has the following methods:

public void Onattachedtowindow ()

SINCE:API Level 5

Called the main window associated with the has been attached to the window manager. View.onattachedtowindow () for the more information.

Also
* Onattachedtowindow ()

Private Boolean catchhomekey = false;
@Override public
void Onattachedtowindow () {
    //TODO auto-generated method Stub
  if (Catchhomekey) {
      This.getwindow (). SetType (WindowManager.LayoutParams.TYPE_KEYGUARD);
    Super.onattachedtowindow ();
}
@Override Public
boolean onKeyDown (int keycode, keyevent event) {
    //TODO auto-generated method stub
    if ( KeyCode = = keyevent.keycode_home) {
        log.e (TAG, "Home key Down");
    }
    Return Super.onkeydown (KeyCode, event);
}

Rewrite the Onattachedtowindow method in the activity and set the type to capture the home key.

When you do not need to capture, delete Settype this line is OK.
