如果在另一个TextView中更改了文本，则重新启动TextView文本动画

标签： java android xml

在TextView1中，文本动画从右向左运行，在TextView2中不断更改文本。问题是，当我在文本动画TextView1重新启动时执行TextView2.setText（＆＃34; ...＆＃34;）。是否可以阻止重新启动动画？

XML代码TextView1：

<TextView
android:id="@+id/artistAlbum"
android:layout_width="wrap_content"
android:layout_height="24dp"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever"
android:paddingTop="2dp"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="text text text text text text text"
android:textSize="14sp" />

Java代码初始化TextView1：

final TextView textView1 = (TextView) rootView.findViewById(R.id.textView1);
textView1.setSelected(true);

XML代码TextView2：

    <TextView
    android:id="@+id/seekSongDuration"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentStart="true"
    android:clickable="true"
    android:paddingBottom="12dp"
    android:paddingEnd="2dp"
    android:paddingStart="10dp"
    android:paddingTop="12dp"
    android:text="0%"
    android:textSize="20sp" />

XML代码：     

    <TextView
        android:id="@+id/fullSongDuration"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
