<application>
<receiver android:name=".MyBroadcastReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.ACTION_SCREEN_ON"></action>
<action android:name="android.intent.action.ACTION_SCREEN_OFF"></action>
</intent-filter>
</receiver>... </application>MyBroadcastReceiver設置只是為了向日志吐出foo。什么也沒做。有什么建議嗎？我是否需要分配任何權(quán)限來捕獲意圖？

或者，您可以使用電源管理器來檢測屏幕鎖定。
@Override
protected void onPause()
{
super.onPause();
// If the screen is off then the device has been locked
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
boolean isScreenOn;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
isScreenOn = powerManager.isInteractive();
} else {
isScreenOn = powerManager.isScreenOn();
}
if (!isScreenOn) {
// The screen has been locked
// do stuff...
}
}
