监听Home键和锁屏键

看代码：

import com.ucoupon.uplus.MyApplication;
import com.ucoupon.uplus.utils.LogUtils;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
/*** Home键和锁屏监听* Title: HomeWatcherReceiver.java* @author wang* 2016年4月25日* @version 1.0*/
public class HomeWatcherReceiver extends BroadcastReceiver {
//  private static final String LOG_TAG = "HomeReceiver";private static final String SYSTEM_DIALOG_REASON_KEY = "reason";private static final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";private static final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";private static final String SYSTEM_DIALOG_REASON_ASSIST = "assist";@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();LogUtils.log_e("action......", action);if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);LogUtils.log_e("reason......", reason);if (SYSTEM_DIALOG_REASON_HOME_KEY.equals(reason)) {// 短按Home键MyApplication.setUpMap = true;LogUtils.log_e("home", "短按Home键");} else if (SYSTEM_DIALOG_REASON_RECENT_APPS.equals(reason)) {// 长按Home键 或者 activity切换键LogUtils.log_e("home", "长按Home键");} else if (SYSTEM_DIALOG_REASON_ASSIST.equals(reason)) {// samsung 长按Home键LogUtils.log_e("home", "samsung长按Home键");}}if(action.equals(Intent.ACTION_SCREEN_ON)){LogUtils.log_e("lock", "Screen is on");}else if(action.equals(Intent.ACTION_SCREEN_OFF)){LogUtils.log_e("lock", "Screen is off");MyApplication.setUpMap = true;}}}

在MainActivity中添加代码：

 private HomeWatcherReceiver receiver;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);registerHomeKeyReceiver();}

// 注册锁屏监听private void registerHomeKeyReceiver() {receiver = new HomeWatcherReceiver();final IntentFilter filter = new IntentFilter();filter.addAction(Intent.ACTION_SCREEN_ON);filter.addAction(Intent.ACTION_SCREEN_OFF);filter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);registerReceiver(receiver, filter);LogUtils.log_e("注册监听", "注册监听");}// 取消锁屏监听private void unregisterHomeKeyReceiver() {if (null != receiver) {unregisterReceiver(receiver);}LogUtils.log_e("取消注册监听", "取消注册监听");}

销毁

 @Overrideprotected void onDestroy() {super.onDestroy();unregisterHomeKeyReceiver();}
