有我的Andr​​oid小工具一个很奇怪的问题嗨即时消息，香港专业教育学院extensivly看了很多地方，但我似乎无法弄清楚什么是错。基本上即时调用我的窗口小部件，并在成功地抓住这一意图在onrecivie方法的PendingIntent播出。

然而，在onRecive方法，当我尝试设置使用RemoteViews我的组件中的文本，该文本不更新，也不是所谓的任何错误。我重视我的低于code，任何帮助将是巨大的。

谢谢，中号

解决方案

您需要几行代码添加到onRecieve方法的末尾....它应该是这样..

另外，虽然我相信你有什么codeD应该工作，但如果没有，你可以尝试把意图行动的按钮在清单文件中。它应该是这样的。

我想现在应该工作。我只是碰巧跌入这个问题我自己，发现这里的解决方案：在Android 可点击小工具

Hi im having a very weird problem with my android widget, ive looked extensivly in many places but I cant seem to figure out whats wrong. basically im calling a pendingintent broadcast in my widget and in sucessfully catching that intent in the onrecivie method.

However in the onRecive method, when I try to set the text using RemoteViews for my component, the text does not update nor is any error called. I have attached my code below, any help would be great.

Thanks, M

 package com.android.FirstWidget;import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ImageButton;
import android.widget.RemoteViews;

public class ExampleAppWidgetProvider extends AppWidgetProvider {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Log.e("ds",intent.getAction());
        Log.e("f","f");
        if(intent.getAction().contains("1")){

            RemoteViews views =  new RemoteViews(context.getPackageName(), R.layout.wid);
            views.setTextViewText(R.id.textView1,"heyheyhey");
            Log.e("fssss","sssf");

            intent.setAction("1");
            PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
            // Get the layout for the App Widget and attach an on-click listener
            // to the button
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.wid);
            views.setOnClickPendingIntent(R.id.arrowLeft, pendingIntent);
           views.setOnClickPendingIntent(R.id.arrowRight, pendingIntent);
//views.set
            // Tell the AppWidgetManager to perform an update on the current app widget
            appWidgetManager.updateAppWidget(appWidgetId, views);

        } 

    }
}

You need to add couple of lines to the end of onRecieve method.... it should go like this..

 package com.android.FirstWidget;import android.app.PendingIntent;
 import android.appwidget.AppWidgetManager;
 import android.appwidget.AppWidgetProvider;
 import android.content.Context;
 import android.content.Intent;
 import android.os.Bundle;
 import android.util.Log;
 import android.view.View;
 import android.widget.ImageButton;
 import android.widget.RemoteViews;

 public class ExampleAppWidgetProvider extends AppWidgetProvider {


     @Override
     public void onReceive(Context context, Intent intent) {
         // TODO Auto-generated method stub
         Log.e("ds",intent.getAction());
         Log.e("f","f");

         RemoteViews views =  new RemoteViews(context.getPackageName(), R.layout.wid);
         if(intent.getAction().contains("arrow_left")){
             views.setTextViewText(R.id.textView1,"left");
             Log.e("fssss","sssf");
         }
         else if(intent.getAction().contains("arrow_right")){
             views.setTextViewText(R.id.textView1,"right");
             Log.e("fssss","sssf");
         }

         else {
             super.onReceive(context, intent);
         }
         ComponentName componentName = new ComponentName(context, ExampleAppWidgetProvider.class);
         AppWidgetManager.getInstance(context).updateAppWidget(componentName, views);
     }

    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        // Perform this loop procedure for each App Widget that belongs to this provider
        for (int i=0; i<N; i++) {
            int appWidgetId = appWidgetIds[i];

            // Create an Intent to launch ExampleActivity
            Intent intent = new Intent(context, ExampleAppWidgetProvider.class);
            intent.setAction("arrow_left");
            PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
            // Get the layout for the App Widget and attach an on-click listener
            // to the button
            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.wid);
            views.setOnClickPendingIntent(R.id.arrowLeft, pendingIntent);

            intent = new Intent(context, ExampleAppWidgetProvider.class);
            intent.setAction("arrow_right");
            pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 
            views.setOnClickPendingIntent(R.id.arrowRight, pendingIntent);
//views.set
            // Tell the AppWidgetManager to perform an update on the current app widget
            appWidgetManager.updateAppWidget(appWidgetId, views);

        } 

    }
}

Also though I believe what you have coded should work, but if not you can try putting the intent action for the buttons in the manifest file. It should go like this

<intent-filter >
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
        <action android:name="com.android.FirstWidget.arrow_left"/>
        <action android:name="com.android.FirstWidget.arrow_right"/>
</intent-filter>

I guess this should work now. I just happen to stumble into this problem myself, and found solution here : Clickable widgets in android
