AlertDialog with custom view doesn't "resize"

Question

I'm facing a problem with the AlertDialog and custom content / view. Simply said the AlertDialog doesn't resize itself when the softkeyboard is opened. The following screenshots show best what my problem is and what I want to achieve:

Current behavior (left) & wanted behavior (right)

I know there a some other threads with a similar issue on SO. Unfortunately none of the provided solutions worked for me. Following my sample code:

XML

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <EditText
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" >
        </EditText>
    </LinearLayout>

</ScrollView>

Java - CustomAlertDialog.class

public class CustomAlertDialog extends AlertDialog{

    private Context context;

    public CustomAlertDialog(Context context) {
        super(context);
        this.context = context;
    }

    public void buildDialog(){
        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.dialog_content, null);
        builder = new AlertDialog.Builder(context);
        builder.setTitle("EditText");
        builder.setView(layout);
        builder.setPositiveButton("Ok", new OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                dismiss();
            }
        });
        builder.create();
    }

    public void showDialog(){
        builder.show();
    }
}

The class / function above is called on a button press in my Main.java class

btnAlertDialog.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            CustomAlertDialog dialog = new CustomAlertDialog(Main.this);
            dialog.buildDialog();
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
            dialog.showDialog();
        }
    });

I've tried the following things:

Adding scrollbars to the LinearLayout like this

android:scrollbars="vertical" 
android:scrollbarAlwaysDrawVerticalTrack="true"

Result: nothing changed

Setting a flag for the dialog:

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

Result: nothing changed

Applying a custom-style to the AlertDialog:

<style name="AlertDialog" parent="@android:style/Theme.Holo.Light">
        <item name="android:windowFullscreen">false</item>
</style>

Java

builder = new AlertDialog.Builder(context, R.style.AlertDialog);

This worked. Unfortunately it produced some problems which you can see the in the following screenshot

I appreciate any help since I've been struggling with this issue for days. Thanks!

Solution

I'm now using the following method to create the Dialog in my CustomAlertDialog.class. See my comment below the answer of nandeesh for further details why it didn't worked before.

public void startDialog(){
        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.dialog_content, null);
        builder = new AlertDialog.Builder(context);
        builder.setTitle("EditText");
        builder.setView(layout);
        builder.setPositiveButton("Ok", new OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                dismiss();
            }
        });
        AlertDialog aDialog = builder.create();
        aDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        aDialog.show();
    }

Answer 1

I am not sure where you did the setSoftInputmode but instead of

builder.show();

use

AlertDialog mDialog = builder.create();
mDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
mDialog.show();

If this does not work, then do post the CustomAlertDialog class
