Android 如何屏蔽Home键

Android 如何屏蔽Home键（长按短按都不起作用）。

package com.test.qiao;

import android.app.Activity;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.WindowManager;

public class ZZZActivity extends Activity {

private boolean flag = true;//true位屏蔽，false位不屏蔽

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}

@Override

public void onAttachedToWindow() {

if(flag) {

this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);

}

super.onAttachedToWindow();

}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if(keyCode == KeyEvent.KEYCODE_HOME){

return true;

}

return super.onKeyDown(keyCode, event);

}

}

$(document).ready(function(){dp.SyntaxHighlighter.HighlightAll('code');});
