我陷入了通知的创建状态。只想在状态栏中显示电池电量(通知栏)通知是永久性的。这是代码的一部分:
private BroadcastReceiver batteryInfoReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
int level= intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
String[] status = {
"Level: "+level
. . .
};
NotificationManager notifi = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,"Level",System.currentTimeMillis());
notification.flags = Notification.FLAG_ONGOING_EVENT;
Intent i = new Intent(context, MainActivity.class);
PendingIntent penInt = PendingIntent.getActivity(getApplicationContext(), 0 , i , 0);
notification.setLatestEventInfo(getApplicationContext(), +level+"%", penInt);
notifi.notify(215,notification);
}
};
这是对的吗?在清单中还有其他东西需要添加吗?我没有指定的通知类,所以我用这种方式编写了这一行:Intent i = new Intent(context, MainActivity.class);
但我不知道它是否正确。
答案 0 :(得分:0)
是的,您需要添加:
<uses-permission android:name="android.permission.BATTERY_STATS" />
