Android的Appwidget TextView中没有更新(Android Appwidget textview not updating)
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"); } super.onReceive(context, intent); } 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 解决方案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; iAlso 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
I guess this should work now. I just happen to stumble into this problem myself, and found solution here : Clickable widgets in android

有我的Android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,

您需要几行代码添加到onRecieve方法的末尾....它应该是这样..

如果(intent.getAction()。包含(“arrow_left”)){
views.setTextViewText(R.id.textView1,“左”);
Log.e(“fssss”,“单一小规模设施”);
}
否则如果(intent.getAction()。包含(“ARROW_RIGHT”)){
views.setTextViewText(R.id.textView1,“右”);
Log.e(“fssss”,“单一小规模设施”);
} 其他{
super.onReceive(背景下,意图);
}
组件名组件名=新的组件名(背景下,ExampleAppWidgetProvider.class);
AppWidgetManager.getInstance(上下文).updateAppWidget(组件名,意见);
} 公共无效的onUpdate(上下文的背景下,AppWidgetManager appWidgetManager,INT [] appWidgetIds){

INT appWidgetId = appWidgetIds [I] //创建一个Intent推出为ExampleActivity

intent.setAction(“arrow_left”);

views.setOnClickPendingIntent(R.id.arrowLeft,的PendingIntent); 意图=新意图(背景下,ExampleAppWidgetProvider.class);
intent.setAction(“ARROW_RIGHT”);
的PendingIntent = PendingIntent.getBroadcast(背景下,0,意向,
views.setOnClickPendingIntent(R.id.arrowRight,的PendingIntent);
//views.set
//告诉AppWidgetManager对当前应用程序窗口小部件进行更新
appWidgetManager.updateAppWidget(appWidgetId,意见); } }
}
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。
<意向滤光器>
<作用机器人:名字=“android.appwidget.action.APPWIDGET_UPDATE”/>
<作用机器人:名字=“com.android.FirstWidget.arrow_left”/>
<作用机器人:名字=“com.android.FirstWidget.arrow_right”/>
&所述; /意图滤光器>
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
