Question

I have an Activity that consists of a large scrollview (that contains EditText fields) along with a button that is anchored to the bottom of the screen (not part of the scrollView). This is a simple example to display the issue I am seeing. The manifest for my app specifies android:windowSoftInputMode = adjustPan for all Activities.

If I run this Activity directly, everything is displayed correctly and the scrollview scrolls between the edit fields as it should.

I don’t have enough points to post images or >2 hyperlinks…..

No TabHost – edit first field

If I run this Activity as the content of a TabHost, the scrolling seems to be borked. Whenever an EditText gains focus, the activity properly pans to the Edit field. However, it also forces the button onto the screen.

Inside TabHost – edit first field – Where did that button come from

I have tried creating the layout for this Activity using a LinearLayout (with negative margin for the button) as well as a RelativeLayout, and both exhibit the same issue with the button always being visible when scrolling through the 3 EditText fields.

Has anyone seen anything like this before or have any idea how to get the scrolling to work properly inside the TabHost ?????

Answer 1

In case this helps someone else…..

All the Activities that were hosted inside the TabHost had android:windowSoftInputMode = adjustPan.

However, the Activity that hosted the TabHost was missing android:windowSoftInputMode = adjustPan.
Once I added that, the panning worked the smae inside a TabHost or outside the TabHost.
