Textview: using the dialog title style: @android:style/TextAppearance.DialogWindowTitle

Question

I am currently trying tu build my own DialogFragment theme.

One of my requirement is to use an icon at the right of the title.

First idea

Simply using:

this.getDialog().getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.dialog_title);

But unfortunately, this line of code has no result.

Second idea

Provinding my own layout -this.setContentView()- with this textview:

<TextView
    android:id="@+id/tvTitle"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="From XML"
    android:textAppearance="@android:style/TextAppearance.DialogWindowTitle" />

This works, because I can read the text, but it still written in default black font.

I was expecting TextAppearance.DialogWindowTitle to give my text a title appareance (blue in Holo with big font size)

Any idea or suggestion?

EDIT

This nearly did the trick:

<style name="Dialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowTitleStyle">@style/MyOwnDialogTitle</item>
</style>

<style name="MyOwnDialogTitle">
    <item name="android:drawableRight">@drawable/MyRightImage</item>
</style>

but android:drawableRight just broke the title layout:

SECOND EDIT

This is a little bit better:

<style name="Dialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowTitleStyle">@style/MyOwnDialogTitle</item>
</style>

<style name="MyOwnDialogTitle">
    <item name="android:textAppearance">@android:style/TextAppearance.DialogWindowTitle</item>
    <item name="android:drawableRight">@drawable/icon</item>
</style>

Answer 1

Maybe you can extend the default style in this manner:

res/values/dialogstyles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="Dialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowTitleStyle">@style/MyOwnDialogTitle</item>
    </style>
    <style name="MyOwnDialogTitle">
        <item name="android:drawableRight">@drawable/MyRightImage</item>
    </style>
</resources>

res/values-v11/dialogstyles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
     <style name="Dialog" parent="@android:style/Theme.Holo.Dialog">
          <item name="android:windowTitleStyle">@style/MyOwnDialogTitle</item>
     </style>
</resources>

And override your DialogFragment's onCreate:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NORMAL, R.style.Dialog);
}

Working Example

Answer 2

I am searching for your first requirement. but for second requirement, why dont you try with changing the color to style of the TextAppearance.DialogWindowTitle with your custom style ?

I have just check the android resources where there is style like below:

  <style name="DialogWindowTitle">
    <item name="android:maxLines">1</item>
    <item name="android:scrollHorizontally">true</item>
    <item name="android:textAppearance">@style/TextAppearance.DialogWindowTitle</item>
</style>

and for TextAppearance.DialogWindowTitle style:

 <style name="TextAppearance.DialogWindowTitle">
    <item name="android:textSize">18sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">?textColorPrimary</item>
</style>

Now, you can change the color of your TextAppearance.DialogWindowTitle style and do as you want.

Hope you got the point.
