01 privatefinalBroadcastReceiverhomePressReceiver=newBroadcastReceiver(){ 02 finalStringSYSTEM_DIALOG_REASON_KEY="reason"; 03 finalStringSYSTEM_DIALOG_REASON_HOME_KEY="homekey"; 04 @Override 05 publicvoidonReceive(Contextcontext,Intentintent){ 06 Stringaction=intent.getAction(); 07 if(action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)){ 08 Stringreason=intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY); 09 if(reason!=null&&reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)){ 10 //自己随意控制程序，关闭... 11 } 12 } 13 } 14 };

然后在onreate()方法中，注册

1 finalIntentFilterhomeFilter=newIntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS); 2 registerReceiver(homePressReceiver,homeFilter);

当然最后为了程序的严谨性也是为了防止出错，我们在onDestory()方法中，也要解除注册

1 if(homePressReceiver!=null){ 2 try{ 3 unregisterReceiver(homePressReceiver); 4 }catch(Exceptione){ 5 Log.e(TAG,"unregisterReceiverhomePressReceiverfailure:"+e.getCause()); 6 } 7 }

2，电源监听，先要有权限

1 <uses-permissionandroid:name="android.permission.WAKE_LOCK"/>

然后监听两个action

01 Intent.ACTION_SCREEN_OFF 02 Intent.ACTION_SCREEN_ON 03 privatefinalBroadcastReceivermBatInfoReceiver=newBroadcastReceiver(){ 04 @Override 05 publicvoidonReceive(finalContextcontext,finalIntentintent){ 06 finalStringaction=intent.getAction(); 07 if(Intent.ACTION_SCREEN_OFF.equals(action)){ 08 //退出程序... 09 } 10 } 11 }; 12 onCreate()方法中注册 13 IntentFilterfilter=newIntentFilter(Intent.ACTION_SCREEN_OFF); 14 registerReceiver(mBatInfoReceiver,filter); 15 onDestory()方法中解除注册 16 if(mBatInfoReceiver!=null){ 17 try{ 18 unregisterReceiver(mBatInfoReceiver); 19 }catch(Exceptione){ 20 Log.e(TAG,"unregisterReceivermBatInfoReceiverfailure:"+e.getCause()); 21 } 22 }
