Android中屏蔽电源键长按、Home键、Home长按

本文主要是介绍Android中屏蔽电源键长按、Home键、Home长按，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

“电源键长按”（globalscreen）

“Home键”（homekey）

“Home长按”（recentapps）

我们可以使用广播来实现，如：

[java] view plain copy print ?

package com.jumpinus.test;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
public class MainActivity extends Activity {
private MyBroadCastReceiver myBroadCastReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
myBroadCastReceiver = new MyBroadCastReceiver();
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
System.out.println(“I’m coming, myBroadCastReceiver注册了!”);
registerReceiver(myBroadCastReceiver, intentFilter);
}
private class MyBroadCastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
//你自己先把 reasons == homekey 和长按homekey 排除，剩下的做下面的处理
String reason = intent.getStringExtra(“reason”);
if (intent.getAction().equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)){
System.out.println("Intent.ACTION_CLOSE_SYSTEM_DIALOGS : " + intent.getStringExtra(“reason”));
if (intent.getExtras()!=null && intent.getExtras().getBoolean(“myReason”)){
myBroadCastReceiver.abortBroadcast();
}else if (reason != null){
if (reason.equalsIgnoreCase(“globalactions”)){
//屏蔽电源长按键的方法：
Intent myIntent = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
myIntent.putExtra(“myReason”, true);
