我试图让一个可调整大小的小部件工作，但它不会。我有一个与 greenDAO 一起使用的数据库。所以我的应用程序应该可以在 Android 2.3+ 上运行。这就是为什么我想拥有以下小部件：
- 4x2 有 2 件物品
- 4x3 有 3 个项目
- 4x4 有 4 个项目
- 4x5 有 5 件物品
在 preHoneycomb 中，这些Widgets应该只显示第一个项目并在点击时打开应用程序。
在 Android 3+ 中，这些widgets应该是可实现和可滚动的。我的问题是我的 Widget Service 类从未被调用过。所以小部件内的任何内容都不会被填充：-
这是我的代码：
public class WidgetProvider extends AppWidgetProvider {
private static final String TAG = "WidgetProvider";
@TargetApi(14)
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
Log.i(TAG, "Update!!");
for (int i = 0; i < appWidgetIds.length; ++i) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, TimetableActivity_.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
Intent svcIntent = new Intent(context, WidgetService.class);
svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
appWidgetIds[i]);
svcIntent.setData(Uri.parse(svcIntent
.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget);
views.setOnClickPendingIntent(R.id.img_widget_home, pendingIntent);
views.setRemoteAdapter(R.id.btn_widget_refresh, svcIntent);
Intent update = new Intent(context, WidgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
PendingIntent pend = PendingIntent.getBroadcast(context, 0, update,
PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.btn_widget_refresh, pend);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
@TargetApi(11)
public class WidgetService extends RemoteViewsService {
private static final String TAG = "WidgetService";
@Override
public RemoteViewsFactory onGetViewFactory(Intent intent) {
Log.i(TAG, "WidgetService called");
return new ListRemoteViewsFactory(this.getApplicationContext(),
(TimetableApplication_) this.getApplication(), intent);
}
}
class ListRemoteViewsFactory implements RemoteViewsService.RemoteViewsFactory {
private static final String TAG = "ListRemoteViewsFactory";
private Context mContext;
private TimetableApplication_ application;
private List<Events> events = new ArrayList<Events>();
public ListRemoteViewsFactory(Context context,
TimetableApplication_ application, Intent intent) {
this.mContext = context;
this.application = application;
}
public int getCount() {
return events.size();
}
public RemoteViews getViewAt(int position) {
Log.i(TAG, ""+getCount());
String title = "";
String description = "";
Events e;
if ((e = events.get(position)) != null) {
title = e.getSubjects().getTitle();
description = e.getStart().toGMTString();
}
RemoteViews rv = new RemoteViews(mContext.getPackageName(),
R.layout.widget_item);
rv.setTextViewText(R.id.txt_widget_item_title, title);
rv.setTextViewText(R.id.txt_widget_item_description, description);
return rv;
}
public RemoteViews getLoadingView() {
return null;
}
public int getViewTypeCount() {
return 1;
}
public long getItemId(int position) {
return position;
}
public boolean hasStableIds() {
return true;
}
public void onDataSetChanged() {
if (events != null) {
events.clear();
}
events = application.getEvents();
}
@Override
public void onCreate() {
}
@Override
public void onDestroy() {
}
}
