[英]BroadcastReceiver isn't receiving ACTION_SCREEN_OFF intent
[英]Why isn't my Screen On/Off BroadcastReceiver working?
這是我的接收器文件。 我覺得沒有任何問題。 我只是打印傳遞的意圖類型。 據我說 onReceive 從來沒有被調用過。 我猜我的清單本身有問題? 還是有其他想法? 接收器未鏈接到應用程序中的任何其他代碼。
package sharukh.locky;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class BroadCastReceiver extends BroadcastReceiver
{
public BroadCastReceiver()
{
}
@Override
public void onReceive(Context context, Intent intent)
{
Log.i("rece", intent.getAction());
}
}
我的清單看起來也不錯,但我不知道為什么它不起作用。

我沒有動態添加/注冊/取消注冊任何接收器。 我需要一些幫助。
您可以通過嘗試動態調用廣播來做到這一點,如下所示
public class YourActivity extends Activity {
//Create broadcast object
BroadcastReceiver mBroadcast = new BroadcastReceiver() {
//When Event is published, onReceive method is called
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i("[BroadcastReceiver]", "MyReceiver");
if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
Log.d("[BroadcastReceiver]", "Screen ON");
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
Log.d("[BroadcastReceiver]", "Screen OFF");
}
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
registerReceiver(mBroadcast, new IntentFilter(Intent.ACTION_SCREEN_ON));
registerReceiver(mBroadcast, new IntentFilter(Intent.ACTION_SCREEN_OFF));
}
}
