How to resize AlertDialog on the Keyboard display

Question

I have a AlertDialog box with approximately 10 controls (text and TextView) on it. These controls are in a ScrollView with AlertDialog, plus I got 2 buttons positive and negative. The issue I have is when the soft keyboard pops up the two buttons are hidden behind the keyboard.

I was looking for something like redraw function on my inner View or the dialog box. Below is the screen shot of what I am talking about.

Answer 1

If your dialog was an activity using one of the Dialog themes you could effect this behavior by setting the adjustResize flag for the windowSoftInputMode parameter of the activity.

I'm using:

android:windowSoftInputMode="adjustResize|stateHidden"

I think you can still use this flag with regular dialogs, but I'm not sure how to apply it. You may have to create your AlertDialog with a custom theme that inherits the right parent theme and also sets that flag, or you might have to use ContextThemeWrappers and stuff.

Or maybe you can just use Window#setSoftInputMode.

alertDialog.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Answer 2

I've found a best way to handle this. Because this is a dialog, So the code

alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

doesn't work very well.

Besides this code, you must set a dialog style for this dialog. The style should like below:

<style name="DialogStyle" parent="@android:style/Theme.Black.NoTitleBar.Fullscreen">
    <item name="android:windowFullscreen">false</item>
    ......
    ......
</style>

NOTICE that the attribute parent is Theme.Black.NoTitleBar.Fullscreen like an activity's style. and the attribute android:windowFullScreen should be false.

Now, the dialog will be resized when the soft keyboard toggles.
