Example code for Android shielding and capturing the home key _android

In Level5 above (included), the method in the Activity class: Publicvoid Onattachedtowindow () captures the home key.

The specific code is as follows:

Mainactivity.java

 package com.lingdududu.test; 
Import android.app.Activity; 
Import Android.os.Bundle; 
Import android.view.KeyEvent; 
Import Android.view.WindowManager; 
 
Import Android.widget.Toast; The public class Mainactivity extends activity {/** called the ' when ' is the ' The activity ' is the ' the '. * Private Boolean created 
 Mekey = false; 
  public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); 
 Setcontentview (R.layout.main); @Override public void Onattachedtowindow () {//TODO auto-generated Method stub if (!catchhomekey) {th 
  Is.getwindow (). SetType (WindowManager.LayoutParams.TYPE_KEYGUARD); 
 } Super.onattachedtowindow (); @Override public boolean onKeyDown (int keycode, keyevent event) {//TODO auto-generated method stub if (key 
  Code = = keyevent.keycode_home) {toast.maketext (Mainactivity.this, "You clicked the Home button", Toast.length_long). Show (); 
 Return Super.onkeydown (KeyCode, event); } 
} 

When we click on the Home button, the program does not return to the main interface, but stays on the current page, and can capture the toast display information.
