android widget textview,Android Appwidget textview不更新

你需要在onRecieve方法的末尾添加几行….它应该像这样..

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

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);

}

}

}

此外,虽然我相信你编码的内容应该可以工作,但如果没有,你可以尝试在清单文件中设置按钮的intent操作.它应该是这样的

我想现在应该可以了.我自己偶然发现了这个问题,并在此找到了解决方案：Clickable widgets in android
