Android WebView Hardware Accelerated Keyboard Glit

Question

When WebView is hardware accelerated, clicking on input field causes keyboard to appear and html is redrawed shifted and duplicated for a moment:

1) When soft keyboard is appearing WebView pans its content to bottom-left, then againt to normal position. Causes short view-able duplication.

2) When changing keyboards (ex. abc->numbers) contents are panned down by keyboard height and then back to normal position. Causes short view-able duplication.

Tested on two Android 4.0 tablets, if hardware accelerations is turned off no such glitches appear.

I failed to found any information on this, has anyone experienced same problem?

Answer 1

So I finally found some solutions:

1. The entire WebView content moves by layout margin width, so setting it to 0px fixes this problem.

2. android:windowSoftInputMode="adjustPan" for WebView activity.
