create style in Android for marquee effect on all TextViews

Question

I want the Marquee effect on EVERY textview in my app...so I thought I put it in a style:

<style name="MyTextViewStyle" parent="@android:style/Widget.TextView">
    <item name="android:focusable">true</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:fontFamily">sans-serif-thin</item>
    <item name="android:textSize">25sp</item>
    <item name="android:ellipsize">marquee</item>
    <item name="android:singleLine">true</item>
    <item name="android:maxLines">1</item>
</style>

and set it in the app theme:

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:textViewStyle">@style/MyTextViewStyle</item>
</style>

this doe not work :(

Tried it directly on the TextView:

<TextView
    android:ellipsize="marquee"
    android:singleLine="true"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:maxLines="1"
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="-5dp"
    android:fontFamily="sans-serif"
    android:textAllCaps="true" />

This does work...

With the following condition: the style may NOT have the 'focusable' and 'focusableInTouchMode' options. But without these uptions in the TextView example above, it will not scroll...

so I need these attributes, but am unable to get them to work via styles...anyone have an answer?

Answer 1

If focusable and focusableInTouchMode not working in Style then remove from Style.xml and add in every TextView

<style name="MyTextViewStyle" parent="@android:style/Widget.TextView">
    <item name="android:fontFamily">sans-serif-thin</item>
    <item name="android:textSize">25sp</item>
    <item name="android:ellipsize">marquee</item>
    <item name="android:singleLine">true</item>
    <item name="android:maxLines">1</item>
</style>



<style name="AppTheme" parent="AppBaseTheme">
<item name="android:textViewStyle">@style/MyTextViewStyle</item>
</style>

In Your layout.xml file.

<TextView
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="-5dp"
    android:textAllCaps="true" />

Note : this will work if there is only one TextView in layout..

If you have many TextView as marquee in single layout then look at this example, Android-MarqueeView.

Answer 2

I'm guessing that android:ellipsize is not a text style element, so it is not inherited with android:textViewStyle.

Just add your MyTextViewStyle as a style to a TextView to check my guess. If this is the problem, you have to add the android:ellipsize attribute individually or in a style.

try this :

<TextView
android:focusable="true"
android:focusableInTouchMode="true"
android:id="@+id/text_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="-5dp"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textAllCaps="true" />

and marquee effect will work only if text length is bigger than scree width.
