键盘关闭后Android操作栏消失

Question

Here's how the situation looks like.

And my layout file is like:

<RelativeLayout>  # Parent
  <RelativeLayout> # Camera preview
  </RelativeLayout>
  <LinearLayout>   # Bottom bar
  </LinearLayout>
</RealtiveLayout>

I understand Android adds/removes views by evaluating whether they are within the view area but I haven't been able to fix this by any means so far.

Using android:windowSoftInputMode="adjustResize" to ensure Actionbar is always visible isn't doable as that spoils the aspect ratio of camera preview above.

Answer 1

See ActionBarSherlock actionbar disappears when focus changes from EditText to Button

For those of you who can't switch to adjustResize . I noticed that actionbar is reappearing after the screen is turned off and on again, so I solved it with this hack:

dialog.setOnDismissListener(dialog1 -> {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        handler.postDelayed(() -> {
            activity.findViewById(android.R.id.content).requestLayout();
        }, 600);
    }
})

This code requests redraw of the whole hierarchy approximately after the keyboard has settled. The checked SDK version and the delay value may be lower, but I decided to play safe.
