从AppWidget开始MainActivity不起作用 [英] Start MainActivity from AppWidget doesn't work
本文介绍了从AppWidget开始MainActivity不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想从我的AppWidget启动我MainActivity与挂起的意图，但我想不出为什么它不火的意图。该插件具有最多3个项目，这是结合于RemoteViewsService一个ListView。我要的是点击任何行的时候开始我MainActivity。谁能告诉我我可能做错了？
我已经查了一些相关的帖子这样启动活动从AppWidget ，甚至试图从这里 https://github.com/运行示例commonsguy / CW-advandroid /树/主/ AppWidget ，虽然样本的作品，仍然无法向我做了什么不同的。
下面是我的一些code的是相关的，请让我知道我是否应该提前发布更多，并且道歉，如果我的帖子不看的权利，因为这是我的第一个问题：

解决方案
我想我找到了答案，或在相关岗位至少一个可行的解决方案：
<一个href=\"http://stackoverflow.com/questions/12958186/adapterviewflipper-in-app-widget-setpendingintenttemplate-and-setonclickfilli\">AdapterViewFlipper在应用小工具：setPendingIntentTemplate（）和setOnClickFillInIntent（）不工作
原来我没有被正确设定FillInIntent。我应该调用setOnClickFillInIntent上列表项，而不是列表本身的顶层视图。这里的code修改，使得它在RemoteViewsFactory工作：
公共RemoteViews getViewAt（INT位置）{
如果（调试）Log.d（LOGTAG，StockRemoteViewsFactory getViewAt位置=+位置）; RemoteViews RV =新的RemoteViews（mContext.getPackageName（），R.layout.widget_item）;
rv.setTextViewText（R.id.text_symbol，mStockItems.get（位置）.getSymbol（））;
rv.setTextViewText（R.id.text_price，的String.format（$％2f上。，mStockItems.get（位置）.getPrice（）））; 意图fillInIntent =新意图（Intent.ACTION_MAIN）;
fillInIntent.putExtra（StockAppWidgetProvider.ITEM_NUM，位置）; //设置列表项的顶层视图，而不是列表视图本身
//rv.setOnClickFillInIntent(R.id.stocks，fillInIntent）;
rv.setOnClickFillInIntent（R.id.general_layout，fillInIntent）; 返回rv;
}
I'm trying to launch my MainActivity from my AppWidget with pending intent but I can't figure out why it doesn't fire the intent. The widget has a ListView with up to 3 items, which is bind to a RemoteViewsService. I want to start my MainActivity when any of the rows is clicked. Can anyone tell me what I might done wrong?
I already checked some related posts like this Launching an activity from an AppWidget, and even tried to run the sample from here https://github.com/commonsguy/cw-advandroid/tree/master/AppWidget, and while the sample works, still can't tell what I did differently.
Here are some of my code that are relevant, please let me know if I should post more, and apologize in advance if my post doesn't look right as this is my first question:
Widget layout:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/stocks"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
AppWidgetProvider class:
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
Log.d(LOGTAG, "onUpdate");
Log.d(LOGTAG, "appWidgetIds.length="+appWidgetIds.length);
for (int i = 0; i < appWidgetIds.length; ++i) {
Log.d(LOGTAG, "appWidgetIds[i]="+appWidgetIds[i]);
}
// update each of the app widgets with the remote adapter
for (int i = 0; i < appWidgetIds.length; ++i) {
updateWidget(context, appWidgetManager, appWidgetIds[i]);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
public void updateWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
Log.d(LOGTAG, "updateWidget id="+appWidgetId);
// Sets up the intent that points to the StackViewService that will
// provide the views for this collection.
Intent intent = new Intent(context, StockAppWidgetService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
// When intents are compared, the extras are ignored, so we need to embed the extras
// into the data so that the extras will not be ignored.
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.stock_appwidget);
rv.setRemoteAdapter(R.id.stocks, intent);
Intent contentIntent = new Intent(context, MainActivity.class);
//contentIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent startAppPendingIntent =
PendingIntent.getActivity(context, 0, contentIntent, 0);
rv.setPendingIntentTemplate(R.id.stocks, startAppPendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, rv);
}

解决方案
I think I found the answer, or at least a workable solution in a related post:
It turns out I wasn't setting the FillInIntent properly. I should call setOnClickFillInIntent on the top level view of the list item instead of the list itself. Here's the code change that made it work in RemoteViewsFactory:
public RemoteViews getViewAt(int position) {
if (DEBUG) Log.d(LOGTAG, "StockRemoteViewsFactory getViewAt position="+position);
RemoteViews rv = new RemoteViews(mContext.getPackageName(), R.layout.widget_item);
rv.setTextViewText(R.id.text_symbol, mStockItems.get(position).getSymbol());
rv.setTextViewText(R.id.text_price, String.format("$%.2f", mStockItems.get(position).getPrice()));
Intent fillInIntent = new Intent(Intent.ACTION_MAIN);
fillInIntent.putExtra(StockAppWidgetProvider.ITEM_NUM, position);
// set on the top level view of the list item, instead of the list view itself
//rv.setOnClickFillInIntent(R.id.stocks, fillInIntent);
rv.setOnClickFillInIntent(R.id.general_layout, fillInIntent);
return rv;
}
