从RemoteViews获取TextView以使其文本可滚动 [英] Get TextView from RemoteViews to make its text scrollable

问题描述

我有一个通过服务的RemoteView构建的通知.

I have a notification built with a RemoteView from a service.

RemoteView布局包含一个我要滚动的TextView.

The RemoteView layout contains a TextView that I want to have it scrolling.

我已经将它设置为xml中的选取框，一切都很好.但是现在我需要设置textView.setSelected(true)，因此我需要以某种方式引用textView.

I've set it up as marquee in the xml, all good. But now I need to set textView.setSelected(true) therefore I need to somehow reference the textView.

那么我该如何从RemoteView获取textView来进行setSelected()?还是有另一种方法可以使其在通知中滚动?

So how do I get the textView from the RemoteView to do setSelected()? Or is there another way to make it scrolling in the notification?

我尝试过

        LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.notification, null);
        TextView text = (TextView) layout.findViewById(R.id.text);
        text.setSelected(true);

或

         View v = views.apply(getApplicationContext(), null);
         TextView text = (TextView) v.findViewById(R.id.text);
         text.setSelected(true);

但是文本没有滚动.

这是我的xml:

<TextView
    android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:duplicateParentState="true"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:gravity="center"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="false"
    android:singleLine="true" >

    <requestFocus
        android:duplicateParentState="true"
        android:focusable="true"
        android:focusableInTouchMode="true" />
</TextView>

推荐答案

这就足够了:

<TextView 
android:id="@+id/text" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:duplicateParentState="true" 
android:ellipsize="marquee" 
android:fadingEdge="horizontal" 
android:focusable="true" 
android:focusableInTouchMode="true" 
android:gravity="center" 
android:marqueeRepeatLimit="marquee_forever" 
android:scrollHorizontally="false" 
android:singleLine="true" > 
    <requestFocus android:duplicateParentState="true" 
        android:focusable="true" 
        android:focusableInTouchMode="true" /> 
</TextView>
