问题描述
我试图让@ + ID / TRACKNAME和@ + ID / artist_and_album使用在以下布局字幕设置，但他们不会滚动。我在实际使用活动的setSelected（真）和setFocusable（真）也试过，但没有奏效。这里是布局的一个图：
I'm trying to get @+id/trackname and @+id/artist_and_album to use the marquee setting in the following layout but they won't scroll. I also tried using setSelected(true) and setFocusable(true) in the actual Activity but that didn't work. Here is a picture of the layout:

推荐答案
我修改了布局：
<LinearLayout

android:layout_width="fill_parent"
android:layout_height="48dip"
android:gravity="center_vertical"
android:orientation="horizontal" >

</RelativeLayout>
</LinearLayout>
我也包括在我的活动下面几行：
I also included the following lines in my activity:
mTrackName = (TextView) findViewById(R.id.trackname);
mTrackName.setSelected(true);
mArtistAndAlbumName = (TextView) findViewById(R.id.artist_and_album);
mArtistAndAlbumName.setSelected(true);
看来原来的布局与嵌套RelativeLayout的是$ P $从滚动pventing文本。
It appears the original layout with the nested RelativeLayout was preventing the text from scrolling.
