WebView doesn't scroll when keyboard opened

Question

I have a WebView that contains an input form. When the user selects the first input the keyboard appears and will scroll the WebView so that the input is uncovered. My problem is in < API 19 when tapping on the next partially obscured input the WebView doesn't scroll. If I were to close the keyboard and then select the input it would scroll correctly.

I've read a lot about if the Activity is FullScreen then it won't work but my app isn't.

Manifest:

Answer 1

You need to add:

android:fitsSystemWindows="true"

to you root of the layout file for the fragment/activity as well as:

android:windowSoftInputMode="adjustResize"

to you activity in the manifest.
