Android How to adjust layout in Full Screen Mode when softkeyboard is visible

Solution

Based on yghm's workaround, I coded up a convenience class that allows me to solve the problem with a one-liner (after adding the new class to my source code of course). The one-liner is:

     AndroidBug5497Workaround.assistActivity(this);

And the implementation class is:

public class AndroidBug5497Workaround {
    
    // For more information, see https://issuetracker.google.com/issues/36911528
    // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.

    public static void assistActivity (Activity activity) {
        new AndroidBug5497Workaround(activity);
    }
    
    private View mChildOfContent;
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;

    private AndroidBug5497Workaround(Activity activity) {
        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                possiblyResizeChildOfContent();
            }
        });
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }

    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard/4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
            } else {
                // keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();
            usableHeightPrevious = usableHeightNow;
        }
    }

    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }
}

Problem

I have researched a lot to adjust the layout when softkeyboard is active and I have successfully implemented it but the problem comes when I use `android:theme="@android:style/Theme.NoTitleBar.Fullscreen"` this in my activity tag in manifest file. For this I have used `android:windowSoftInputMode="adjustPan|adjustResize|stateHidden"` with different options but no luck. After that I implemented `FullScreen` programmatically and tried various layout to work with `FullScreen` but all in vain. I referred these links and have looked many posts here related to this issue: http://android-developers.blogspot.com/2009/04/updating-applications-for-on-screen.html http://davidwparker.com/2011/08/30/android-how-to-float-a-row-above-keyboard/ Here is xml code: ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/masterContainerView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android" android:background="#ffffff"> <ScrollView android:id="@+id/parentScrollView" android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <TextView android:id="@+id/setup_txt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Setup - Step 1 of 3" android:textColor="@color/top_header_txt_color" android:textSize="20dp" android:padding="8dp" android:gravity="center_horizontal" /> <TextView android:id="@+id/txt_header" android:layout_width="fill_parent" android:layout_height="40dp" android:text="AutoReply:" android:textColor="@color/top_header_txt_color" android:textSize="14dp" android:textStyle="bold" android:padding="10dp" android:layout_below="@+id/setup_txt" /> <EditText android:id="@+id/edit_message" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Some text here." android:textSize="16dp" android:textColor="@color/setting_editmsg_color" android:padding="10dp" android:minLines="5" android:maxLines="6" android:layout_below="@+id/txt_header" android:gravity="top" android:scrollbars="vertical" android:maxLength="132" /> <ImageView android:id="@+id/image_bottom" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/edit_message" /> </LinearLayout> </ScrollView> <RelativeLayout android:id="@+id/scoringContainerView" android:layout_width="fill_parent" android:layout_height="50px" android:orientation="vertical" android:layout_alignParentBottom="true" android:background="#535254"> <Button android:id="@+id/btn_save" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginTop="7dp" android:layout_marginRight="15dp" android:layout_below="@+id/edit_message" android:text = "Save" /> <Button android:id="@+id/btn_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="7dp" android:layout_marginRight="10dp" android:layout_below="@+id/edit_message" android:layout_toLeftOf="@+id/btn_save" android:text = "Cancel" /> </RelativeLayout> </RelativeLayout> ``` I want the bottom 2 buttons should go upward when the softkeyboard comes in picture.
