Android小工具：添加一个新项目（“作者”）textview

Question

每个人，我正在开发一个简单的Android小部件（“行情”）。该项目工作正常，但我想添加一个新的文本视图，显示特定“思想”的作者。我在widget.xml（布局）中创建了一个新的textview ....我是一个新手！

下面的代码是：

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 java.io.InputStream; 
    import java.io.InputStreamReader; 
    import java.util.ArrayList; 
    import java.util.List; 
    import java.util.Random; 



    import android.app.Service; 
    import android.appwidget.AppWidgetManager; 
    import android.content.Intent; 
    import android.content.res.AssetManager; 
    import android.os.IBinder; 
    import android.util.Log; 
    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; 

} 

    }

我想你Ç不会在小部件中创建文本视图。只有点击和触摸才有可能在小工具
