[問題] 關閉螢幕後怎麼維持Sensor開啟狀態
為了解決關螢幕之後無法偵測的問題
我參考網路用Broadcast的方式在偵測到關螢幕時重新註冊Sensor
但至今仍然無解...
public BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// Check action just to be on the safe side.
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
// Unregisters the listener and registers it again.
mSensorManager.unregisterListener(AccelerometerService.this);
mSensorManager.registerListener(AccelerometerService.this,
mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL);
}
}
};
後來用eclipse紀錄狀態：Log.v(“Accelerometer Working”, “Accelerometer
Working”, );
發現只要一關掉螢幕Sensor就停掉不再回傳data了
PS.不是Broadcast的問題，因為我試過加入一段倒數10秒的trigger，螢幕確實會自己開
起來
Anyone can help me about this?
