[導(dǎo)讀] 01 private final BroadcastReceiver homePressReceiver = new BroadcastReceiver() { 02

`01`	`private` `final` `BroadcastReceiver homePressReceiver =` `new` `BroadcastReceiver() {`

`02`	`final` `String SYSTEM_DIALOG_REASON_KEY =` `"reason";`

`03`	`final` `String SYSTEM_DIALOG_REASON_HOME_KEY =` `"homekey";`

`04`	`@Override`

`05`	`public` `void` `onReceive(Context context, Intent intent) {`

`06`	`String action = intent.getAction();`

`07`	`if` `(action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {`

`08`	`String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);`

`09`	`if` `(reason !=` `null` `&& reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {`

`10`	`//自己隨意控制程序，關(guān)閉...`

11 }

12 }

13 }

14 };

然后在onreate()方法中，注冊(cè)

`1`	`final` `IntentFilter homeFilter =` `new` `IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);`

`2`	`registerReceiver(homePressReceiver, homeFilter);`

當(dāng)然最后為了程序的嚴(yán)謹(jǐn)性也是為了防止出錯(cuò)，我們?cè)趏nDestory()方法中，也要解除注冊(cè)

`1`	`if(homePressReceiver !=` `null){`

2 try {

`3`	`unregisterReceiver(homePressReceiver);`

`4`	`}` `catch` `(Exception e) {`

`5`	`Log.e(TAG,` `"unregisterReceiver homePressReceiver failure :"+e.getCause());`

6 }

7 }

2，電源監(jiān)聽(tīng)，先要有權(quán)限

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

然后監(jiān)聽(tīng)兩個(gè)action

`01`	`Intent.ACTION_SCREEN_OFF`

`02`	`Intent.ACTION_SCREEN_ON`

`03`	`private` `final` `BroadcastReceiver mBatInfoReceiver =` `new` `BroadcastReceiver() {`

`04`	`@Override`

`05`	`public` `void` `onReceive(final` `Context context,` `final` `Intent intent) {`

`06`	`final` `String action = intent.getAction();`

`07`	`if` `(Intent.ACTION_SCREEN_OFF.equals(action)) {`

`08`	`//退出程序...`

09 }

10 }

11 };

`12`	`onCreate()方法中注冊(cè)`

`13`	`IntentFilter filter =` `new` `IntentFilter(Intent.ACTION_SCREEN_OFF);`

`14`	`registerReceiver(mBatInfoReceiver, filter);`

`15`	`onDestory()方法中解除注冊(cè)`

`16`	`if(mBatInfoReceiver !=` `null){`

17 try {

`18`	`unregisterReceiver(mBatInfoReceiver);`

`19`	`}` `catch` `(Exception e) {`

`20`	`Log.e(TAG,` `"unregisterReceiver mBatInfoReceiver failure :"+e.getCause());`

21 }

22 }
