Question

我正在为主屏幕构建一个小部件，现在我增加了时间，我想增加电池百分比，我该怎么做？

公共类HelloWidget扩展AppWidgetProvider {

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager), 1, 1000);
}

private class MyTime extends TimerTask {
    RemoteViews remoteViews;
    AppWidgetManager appWidgetManager;
    ComponentName thisWidget;
    DateFormat format = SimpleDateFormat.getTimeInstance(SimpleDateFormat.MEDIUM, Locale.getDefault());

public MyTime(Context context, AppWidgetManager appWidgetManager) {
    this.appWidgetManager = appWidgetManager;
    remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
    thisWidget = new ComponentName(context, HelloWidget.class);
}

@Override
public void run() {
    remoteViews.setTextViewText(R.id.widget_textview, format.format(new Date()));
    appWidgetManager.updateAppWidget(thisWidget, remoteViews);
}

}

}

这是我的主要java文件，任何添加百分比的方法？

我试过这个

  private TextView batteryTxt;
  private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
    @Override
    public void onReceive(Context ctxt, Intent intent) {
      int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
      batteryTxt.setText(String.valueOf(level) + "%");
    }
  };

  @Override
  public void onCreate(Bundle b) {
    super.onCreate(b);
    setContentView(R.layout.main);
    contentTxt = (TextView) this.findViewById(R.id.batteryTxt);
    this.registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
  }
}

但我不能但是没错，请帮忙
