Using the same view on both tabs in Android
I'm working on an Android
application with an activity that uses a tab layout. There are two tabs which switch between the content being shown in a ListView
below.
This means that the two tab specifications point to the same ListView
for content, R.id.main_list
:
<TabWidget
android:id="@andr开发者_如何学编程oid:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="@+id/main_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
This somewhat works - if I switch to tab #2 and back to #1, I can see the ListView
and my database code gets the right data based on the selected tab. However, when the activity launches, the ListView
can't be seen before tabs are changed. This is obviously a problem.
What's the least hacky way to get around this?
Use two ListView
widgets.
