android - Android ウィジェット: 新しい項目 (「作成者」) のテキストビューを追加する

Question

皆さん、私はシンプルな Android ウィジェット ("Quotes") を開発しています。プロジェクトは正常に動作していますが、特定の「考え」の作成者を示す新しいテキストビューを追加したいと思います。widget.xml (レイアウト) に新しいテキストビューを作成しました。初心者です!!!

コードは次のとおりです。

WidgetQuotes.Java

  import android.app.PendingIntent;
  import android.appwidget.AppWidgetManager;
  import android.appwidget.AppWidgetProvider;
  import android.content.Context;
  import android.content.Intent;
  import android.widget.RemoteViews;

   public class WidgetQuotes extends AppWidgetProvider {

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

    // Build the intent to call the service
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
    Intent intent = new Intent(context.getApplicationContext(), UpdateWidgetService.class);
    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);

    RemoteViews remoteViews2 = new RemoteViews(context.getPackageName(), R.layout.widget);
    Intent intent2 = new Intent(context.getApplicationContext(), UpdateWidgetService.class);
    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);

    // To react to a click we have to use a pending intent as the
    // onClickListener is
    // excecuted by the homescreen application
    PendingIntent pendingIntent = PendingIntent.getService(
            context.getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    remoteViews.setOnClickPendingIntent(R.id.widget_textview, pendingIntent);


    PendingIntent pendingIntent2 = PendingIntent.getService(
            context.getApplicationContext(), 0, intent2, PendingIntent.FLAG_UPDATE_CURRENT);

    remoteViews2.setOnClickPendingIntent(R.id.widget_textview2, pendingIntent2);


    // Finally update all widgets with the information about the click
    // listener
    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);

    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews2);

    // Update the widgets via the service
    context.startService(intent);
    context.startService(intent2);
}

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);

}
public void onReceive1(Context context, Intent intent2) {   
    super.onReceive(context, intent2);
}



}

UpdateWidgetService.Java

    import java.io.BufferedReader;
    import java.io.IOException;

   import android.widget.RemoteViews;

   public class UpdateWidgetService extends Service {
private static final String TAG = UpdateWidgetService.class.getSimpleName();

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

@Override
public void onStart(Intent intent, int startId) {
    super.onStart(intent, startId);

    Log.d(TAG, "onStart started");

    // Create some random data
    Random random = new Random();

    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this.getApplicationContext());

    int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);

    if (appWidgetIds.length > 0) {

        for (int widgetId : appWidgetIds) {
            List<String> qList = getListFromTxtFile("quotes.txt");
            int nextInt = random.nextInt(qList.size());

            RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.widget);
            remoteViews.setTextViewText(R.id.widget_textview, qList.get(nextInt));
            appWidgetManager.updateAppWidget(widgetId, remoteViews);
        }
        stopSelf();
    }
    super.onStart(intent, startId);
}

public List<String> getListFromTxtFile(String txtFileName){

//  File sdcard = Environment.getExternalStorageDirectory();
// Get the text file
// File file = new File(sdcard,txtFileName);

AssetManager am = this.getAssets();

List<String> qList = new ArrayList<String>();

//Read text from file

try {
    InputStream is = am.open("quotes.txt");
          //BufferedReader br = new BufferedReader(new FileReader(file));
    BufferedReader br = new BufferedReader(new InputStreamReader(is));
    String line;

     // get data in text file line by line
    while ((line = br.readLine()) != null) {

        Log.d("line",line);

       qList.add(line);
    }
}
catch (IOException e) {
    //You'll need to add proper error handling here

    {Log.d("Error","There are an error");}
}
return qList;

}

   }
