Thank you very much for your help, with your approach to indeed achieve a shield home button, but brings along a problem that the screen (my lock screen activity) can not respond to touch events, and I want the user by clicking on the screen block all keys except the off button on the outside of the button to unlock, so I based on your tips to your methods were slightly modified to achieve the full screen and can respond to the keyboard. Share my method:
================================================== ===============
Statement permissions:



Declare the function and activity class members:

Runnable mDisableHomeKeyRunnable = new Runnable () {

@ Override
public void run () {
disableHomeKey ();

}
};

Handler mHandler = new Handler ();

public void disableHomeKey ()
{
this.getWindow () setType (WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);.
}

In onCreate call:
mHandler.postDelayed (mDisableHomeKeyRunnable, 200);
================================================== ============
