Style attributes of custom styled AlertDialog

Question

I am trying to style my AlertDialog and I have been able to change most of it through styles and xml declarations... but there are still a few issues:

1. How do I change the area around the title bar from black to my custom color?
2. How do I change the outer background to transparent (the outside part that is blue the the shadow drops upon)
3. How do I change the buttons so they do not overlap the black border around the alert message?

here is the function I have in my RootActivity (my activities extend this one)

public static void showNoConnectionDialog(Context ctx1) {
    final Context ctx = ctx1;
    LayoutInflater factory = LayoutInflater.from(ctx);
    AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(ctx, R.style.SetdartDialog));
    builder.setView(factory.inflate(R.layout.alert_dialog, null))
    .setIcon(R.drawable.icon)
    .setCancelable(true)
    .setMessage(R.string.check_wireless_settings)
    .setTitle(R.string.no_connection)
    .setPositiveButton(R.string.myes, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            ctx.startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
        }
    })
    .setNegativeButton(R.string.mno, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            return;
        }
    })
    .setOnCancelListener(new DialogInterface.OnCancelListener() {
        public void onCancel(DialogInterface dialog) {
            return;
        }
    })
    .show();
}

here a snippet from styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.WhiteBackground" parent="android:Theme">
        <item name="android:windowBackground">@null</item>
        <item name="android:background">@android:color/white</item>
        <!-- Dialog attributes
        <item name="alertDialogStyle">@style/AlertDialog</item>  -->
    </style>
    <style name="SetdartDialog">
            <item name="android:background">@color/sd_blue</item> <!-- MUST HAVE with white bg-->
            <!--<item name="android:windowBackground">@color/sd_blue</item> -->
            <!--<item name="android:windowBackground">@color/transparent</item> needed with white bg ? -->
            <item name="android:windowFrame">@color/transparent</item><!-- not sure what this changes-->
            <item name="android:textColor">@android:color/black</item>
            <item name="android:windowNoTitle">true</item>
            <item name="android:textSize">10sp</item>
            <item name="android:windowIsFloating">true</item>
            <item name="android:windowContentOverlay">@color/transparent</item>
            <item name="android:windowTitleStyle">@style/setwindowTitleStyle</item>
            <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
            <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
            <item name="android:backgroundDimEnabled">true</item>
            <item name="android:gravity">center_vertical|center_horizontal</item>
        <!--<item name="android:colorBackgroundCacheHint">@android:color/white</item>-->
        </style>
        <style name="setwindowTitleStyle">
            <item name="android:textColor">@android:color/white</item>
            <item name="android:background">@color/sd_blue</item>
        </style>
</resources>

Also R.layout.alert_dialog

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/screen"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:orientation="vertical"
    >
    <LinearLayout
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:orientation="vertical">
    </LinearLayout>
</ScrollView>

Answer 1

To make custom AlertDialog you should extend DialogFragment

Answer 2

Create your custom layout with all these attributes you've mentioned. Use Dialog instead of AlertDialog, inflate the layout you have created, use the Dialog object to set the inflated layout. If you haven't been introduced to inflating service, do some research. After you are clear with inflating, remember that all the components of the dialog you access with the View object, that you have created with the inflating. The rest (like click listeners) remains to be done on usual way. Cheers. I hope it helps.
