Custom notification marquee text doesnt work android

问题

Hi im trying to make part of my text in the notification manager marquee but doesnt work i tried this:

  <TextView
    android:id="@+id/title_text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:gravity="bottom"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="true"                                     
    android:focusable="true"
    android:focusableInTouchMode="true"              
    android:singleLine="true"
    android:textSize="15sp"
    android:textStyle="bold" >
  </TextView>

and in my .java i use remoteview:

Notification notification = new Notification(icon, tickerText, when);
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);

contentView.setTextViewText(R.id.title_text, "This is a very long text which is not fitting in the screen so it needs to be marqueed");

i would like to have marquee for that title_text This is a very long text which is not fitting in the screen so it needs to be marqueed

but the marquee doesnt work just stays static what i can do?

thank you.

i changed my xml:

  <TextView
    android:id="@+id/title_text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:gravity="bottom"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="false"                                     
    android:focusable="true"
    android:focusableInTouchMode="true"              
    android:singleLine="true"
    android:textSize="15sp"
    android:textStyle="bold" 
    android:textColor="#fff">
    <requestFocus/> 
  </TextView>

i added <requestFocus/> and now my marquee works perfect.

According to the docs, setting the scrollHorizontally attribute to true will NOT wrap the text at the edge. Try setting it to false so the ellipsize attribute is used.

I lost a day to realize thats the marquee effect is done by this method from NotificationCompat.Builder: setTicker which support RemoteView

I really hope that answer save many lives :) (almost lost my hair)
