How to resize AlertDialog on the Keyboard display

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);

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.

Nothing worked for me except adjustPan

as per the documentation

The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

So just simply use it in your onCreate() or onCreateView() method like:

getDialog().getWindow().setSoftInputMode(            WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

Or simply put android:windowSoftInputMode="adjustPan" in manifest for the Activiry in which we are playing with dialogs

and use android:windowSoftInputMode="adjustResize|stateHidden" in each edittext which will help the user to navigate to next textbox easily.

Point to remember

Never use MATCH_PARENT to make the dialog full screen as adjustPan will not work here. If anyone wants to make the dialog to fit the screen, just use points till 0.96 (not more than this) for the height, so the keyboard will properly reach to the edittext. I did like below :

@Overridepublic void onStart(){    super.onStart();    Dialog dialog = getDialog();    if (dialog != null)    {        //int height = ViewGroup.LayoutParams.MATCH_PARENT;        int width = ViewGroup.LayoutParams.MATCH_PARENT;        Display display = getActivity().getWindowManager().getDefaultDisplay();        Point size = new Point();        display.getSize(size);        //int width = (int)(size.x * 0.96);        int h = (int)(size.y * 0.96);        dialog.getWindow().setLayout(width, h);    }}

Look, If I will use the total height (MATCH_PARENT) then soft_keyboard will squize the dialog. But if I will use points for the height (here 0.96 which is almost near to match_parent), then it will properly work.

Hope it will help someone :)
