我正在开发Android小部件,我在Web服务上显示了该小部件上的一些数据,并且工作正常.Hear是代码。
代码
public class WatchWidget extends AppWidgetProvider{
private static final String TAG = "WatchWidget";
@Override
public void onUpdate( Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds ){
Log.i(TAG, "* onUpdate");
EBWeaterData ebwd=new EBWeaterData();
EBWeatreUtils.getWeatherFeeds(context, ebwd, "my url to get data");
RemoteViews views = new RemoteViews(context.getPackageName(),R.layout.main);
RemoteViews newView = new RemoteViews(context.getPackageName(), R.layout.test);
//get data
String day=ebwd.getDay_1()+ebwd.getDay_suffix_1()+" "+ebwd.getDay_name_1();
String minmaxtemp="Max Temp "+ebwd.getDay_max_temp_1()+"°C "+"Min Temp "+ebwd.getDay_min_temp_1()+"°C";
//set dat to views
newView.setTextViewText(R.id.textView_day_name, day);
newView.setTextViewText(R.id.textView_minmaxtemp, minmaxtemp);
newView.setImageViewResource(R.id.ImageView_icon, R.drawable.sunny);
views.addView(R.id.view_container, newView);
ComponentName thisWidget = new ComponentName(context,WatchWidget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(context);
manager.updateAppWidget(thisWidget, views);
}
}
我在该窗口小部件上有一个按钮现在我想在用户点击按钮时用不同的值更新窗口小部件视图。我知道我必须处理pendingIntent,如下所示。
Intent intent = new Intent(context, activitytogetNewdata.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.imageView1, pendingIntent);
但它会启动另一个我不想去另一个活动的活动。我只需要点击按钮后用新值更新相同的小部件视图。任何想法?

我发现了我的代码问题。当我要使用pendingintent更新我的视图时,它将动态添加每个按钮点击的视图因为我使用了2个布局听到所以我解决了如下问题。(我使用一个布局而不是两个)

}
