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:

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!

Answer 1

尝试这个 ：

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

Answer 2

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.
