Android: Dialog not full screen OR AlertDialog without weird background in Android 2.3

Question

I'm developing an Android application where I have Dialogs with custom layout. At first I decided to use AlertDialog without title and without buttons, since I have my own Buttons in my custom layout. This works fine in Android 4.4, but not in Android 2.3.

This is how it's seen in Android 4.4:

This is how it's seen in Android 2.3:

Please notice the weird gray background behind my Dialog.

In SO I saw that some people solved it using Dialog instead of AlertDialog. I tried it and it really fixed it, but now my Dialog fills the whole screen:

enter image description here

And I don't want that, I want the Dialog to have some margin like the AlertDialog has.

This is my layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/dialog_background"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/adTitleTextView"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_marginLeft="1dp"
        android:layout_marginRight="1dp"
        android:layout_marginTop="1dp"
        android:background="@drawable/background_green"
        android:gravity="center"
        android:textColor="#FFFFFFFF"
        android:textSize="20sp" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="2dp"
        android:background="#FFFFFFFF" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:paddingBottom="15dp"
        android:paddingTop="10dp" 
        android:textColor="#FFFFFFFF" />

    <LinearLayout
        android:id="@+id/adButtonBar"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/adNegativeButton"
            android:layout_width="0dip"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/selector_button_alert_dialog"
            android:textColor="#FFFFFFFF"
            android:textSize="14sp" />

        <Button
            android:id="@+id/adNeutralButton"
            android:layout_width="0dip"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/selector_button_alert_dialog"
            android:textColor="#FFFFFFFF"
            android:textSize="14sp" />

        <Button
            android:id="@+id/adPositiveButton"
            android:layout_width="0dip"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/selector_button_alert_dialog"
            android:textColor="#FFFFFFFF"
            android:textSize="14sp" />

    </LinearLayout>

</LinearLayout>

This is how I create my Dialog:

    Dialog mDialog = new Dialog( this, android.R.style.Theme_Dialog );
    mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    View content = getLayoutInflater().inflate( R.layout.alert_dialog_layout, null);
    ((TextView)content.findViewById(R.id.adTitleTextView)).setText( title );
    ((TextView) content.findViewById( R.id.adBodyTextView )).setText( message );    

    mDialog.setContentView( content );

    Button b = (Button) content.findViewById(R.id.adPositiveButton);
    b.setText( posText );
    b.setOnClickListener( this );

    b = (Button) content.findViewById(R.id.adNegaveButton);
    b.setText( negText );
    b.setOnClickListener( this );

    mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    mDialog.show();

And this is how I create the AlertDialog:

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder( ctx );

    alertDialogBuilder.setView( content );

    final AlertDialog mDialog = alertDialogBuilder.create();
    mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    ...

Anybody knows how can I remove that weird background from AlertDialog in Android 2.3 OR how to make Dialog not to fill the whole screen?

Thank you!

it's seems like your both images are same then where is the issue? — M D, Feb 28 '14 at 10:17
Like I explain in my post, if I use AlertDialog (images 1 and 2) I see a weird gray background behind the Dialog in Android 2.3 (please look at image 2). If I use Dialog (image 3), the Dialog fills the screen horizontally (please look at image 3), and I want it to be like Image 1, with some margin. — PX Developer, Feb 28 '14 at 10:23
tell me first you added `Theme_Dialog` for all the `Android Version` separately into values `styles.xml`. — M D, Feb 28 '14 at 10:27
I'm using `Android`'s default `Theme_Dialog` style, not a custom one, so I guess `Android` already has it for all versions, right? I added it because in the following post they say it fixes the full screen `Dialog` issue, but it doesn't work for me: http://stackoverflow.com/questions/17484863/custom-dialog-opens-full-screen — PX Developer, Feb 28 '14 at 10:33
No no you go wrong over here.ok fine post your `Theme_Dialog` over here — M D, Feb 28 '14 at 10:33
I don't have a Theme_Dialog, I'm using android.R.style.Theme_Dialog: http://developer.android.com/reference/android/R.style.html#Theme_Dialog — PX Developer, Feb 28 '14 at 10:37
The backgrounds are set in the custom layout, like you can see in my post: android:background="@drawable/dialog_background". — PX Developer, Feb 28 '14 at 10:38

I finally found a solution for this, although I don't like it much. I'm solving the Dialog not full screen issue.

Basically, I set the width programmatically and, if the height exceeds a certain value, I set it too:

    content.getLayoutParams().width = (int) (screenWidth * 0.95);

    content.post(new Runnable() {

        @Override
        public void run() {             

            int newMaxHeight = content.findViewById(R.id.adTitleTextView).getHeight() + 
                    content.findViewById(R.id.adBodyContainer).getHeight() + 
                    content.findViewById(R.id.adButtonBar).getHeight();             


            if( newMaxHeight > screenHeight * 0.92 ){

                content.getLayoutParams().height = (int) (screenHeight * 0.92);

                content.findViewById(R.id.adBodyContainer).getLayoutParams().height = 
                        (int) (screenHeight * 0.92) - content.findViewById(R.id.adTitleTextView).getHeight()
                        - content.findViewById(R.id.adButtonBar).getHeight();

            }

        }
    });

With this code I can limit the maximum width and height of the Dialog. If anybody finds a better solution, please post it here.

Try this :

dialog.getWindow().setLayout(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

It's still filling the screen. I tried using it before and after using dialog.show(), but it's still the same. – PX Developer Feb 28 '14 at 10:49
Did you try using that with AlertDialog or Dialog? – TMH Feb 28 '14 at 11:39
