android长按home键设置的,Android中屏蔽电源键长按、Home键、Home键长按

Android中屏蔽电源键长按、Home键、Home键长按 这几个“按钮”的触发，都会产生一个Action ==Intent.ACTION_CLOSE_SYSTEM_DIALOGS的通知 区分他们三个的不同事件

Android中屏蔽"电源键长按"、"Home键"、"Home键长按"

这几个“按钮”的触发，都会产生一个Action == Intent.ACTION_CLOSE_SYSTEM_DIALOGS的通知

区分他们三个的不同事件的参数，就是随着Intent带过来的reason字符串，分别对应

"电源键长按"(globalscreen)、"Home键"(homekey)、"Home键长按"(recentapps)

说破了就这么简单，直接上代码了。

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);

context.sendOrderedBroadcast(myIntent, null);

System.out.println("电源 键被长按");

}else if (reason.equalsIgnoreCase("homekey")){

//屏蔽Home键的方法

//在这里做一些你自己想要的操作,比如重新打开自己的锁屏程序界面，这样子就不会消失了

System.out.println("Home 键被触发");

}else if (reason.equalsIgnoreCase("recentapps")){

//屏蔽Home键长按的方法

System.out.println("Home 键被长按");

}

}

}

}

}

@Override

protected void onPause() {

// TODO Auto-generated method stub

super.onPause();

System.out.println("I get out, myBroadCastReceiver注销了!");

unregisterReceiver(myBroadCastReceiver);

}

}
