In project development, it may be necessary to block the Android virtual keys, where the return key is relatively easy to disable, the following two ways to solve:

@Override Public    boolean onKeyDown (int keycode, keyevent event) {  if (keycode = = keyevent.keycode_back) {      return  true;}  Return  Super.onkeydown (KeyCode, event);     

Or

@Overridepublic void onbackpressed () {}

Next explain how to block the home key:

1, download the above resources, unzip the file;

2. Copy the Homekeylocker.java file to your project;

3.

<style name= "Overlaydialog" parent= "@android: Style/theme.dialog" >        <item name= "Android: Windowbackground "> @android:color/transparent</item>        <item name=" Android:windowframe "> @null </item>        <item name= "Android:windownotitle" >true</item>        <item name= "Android: Windowisfloating ">true</item>        <item name=" Android:windowistranslucent ">false</item>        <item name= "android:backgrounddimenabled" >false</item>    </style>

Copy to your styles.xml file;

4, will

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

Copied to the Androidmanifest.xml file;

5. Add code to the activity file that you want to block:

Private Homekeylocker Mhomekeylocker;

public void OnCreate (Bundle parambundle) {<span style= "white-space:pre" ></span>mhomekeylocker = new Homekeylocker (); <span style= "White-space:pre" ></span>mhomekeylocker.lock (LoginActivity.this);}

protected void OnDestroy () {<span style= "White-space:pre" ></span>mhomekeylocker.unlock (); Mhomekeylocker = Null;super.ondestroy ();}

。

The 5 steps above can be implemented to disable the home key.
