This is an android study note about the home key.

Proposal of proposal

The android HOME key system is responsible for monitoring and automatically processes the captured data. Sometimes, the processing of the system often does not mean anything. What should we do if we want to handle the event after clicking home on our own?

 

Solution to the Failover Problem

Disable the Home key first, and then process the key value in onkeydown. When you click the Home Key, close the program or follow your 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 method stub

This. getwindow (). settype (windowmanager. layoutparams. type_keyguard );

Super. onattachedtowindow ();

}

 

 

Add the permission to prohibit the Home Key

<Uses-Permission Android: Name = "android. Permission. disable_keyguard"> </uses-Permission>
