Custom title and summary only on preference

[nambv]

When using custom preference, if you want to change only title and summary textview attributes, you can override layout preference xml and keep widget layout as the same as original.

Here is the custom xml layout:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="8dp"
    android:paddingRight="8dp"
    android:paddingTop="@dimen/activity_vertical_margin">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical">

        <TextView
            android:id="@+android:id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/colorBlack"/>

        <TextView
            android:id="@+android:id/summary"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceSmall"/>

    </LinearLayout>

    <!-- Preference should place its actual preference widget here. -->
    <LinearLayout
        android:id="@+android:id/widget_frame"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:gravity="center_vertical"
        android:orientation="vertical"/>

</LinearLayout>
