Question

是否有办法从案文中获取价值植被内的观点? 我在我的植被布局和我的植被更新方面有两点文字,我想给其中一人带来新的价值,我不想改变第二点的价值。现在,我把这种价值确定为这样的价值。

   remoteViews.setTextViewText(R.id.text1, newValue");
   widgetManager.updateAppWidget(thisWidget, remoteViews);

this is setting value of the second textView to default value defined in layout. How to get it to not change the value of the second textView, or how to get value to the second textView to be able to adjust to the same ?

我的理解是,每当打电话到onUpdate时,它就更新了所有植被,因此我使用的是共享优惠,因此,当我设定了<条码>TextView时,首先,我只读了文本,供大家分享。我在<条码>范围内这样做。

我的<代码>上:

@Override
public void onUpdate(Context context, AppWidgetManager awm, int[] appWidgetIds){
    SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(context);
    int appWidgetId;
    for (int i=0;i<appWidgetIds.length;i++){
            appWidgetId = appWidgetIds[i];

            String widgetLabel = pref.getString("label"+appWidgetId, "");
            // I previously saved "widgetLabel" when I created the widget in my 
            // ConfigurationActivity
            M.updateWidget(context, appWidgetId, widgetLabel);
                // I put this in another class so it s more manageable.
        }



}

在我的M级:

public static void updateWidget(Context context, int appWidgetId, String widgetLabel){

        SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(context).edit();

        RemoteViews updateViews;
        int layoutId = R.layout.layout;
        int viewId = R.id.layout;

        updateViews = new RemoteViews(context.getPackageName(),
                layoutId);
        updateViews.setTextViewText(R.id.widgetlabel, widgetLabel);
        editor.putString("label"+appWidgetId, widgetLabel);
        editor.commit();

        Intent intent = new Intent(context, ClickAction.class); 
        PendingIntent pendingIntent = PendingIntent.getActivity(context, appWidgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        updateViews.setOnClickPendingIntent(viewId, pendingIntent);

        AppWidgetManager.getInstance(context).updateAppWidget(appWidgetId, updateViews);
    }

我希望这一点是有意义的。让我知道,我是否需要详细阐述任何问题。
