Question

我在appwidget中对单个textview实现了marque效果。但每当我再添加一个textview。它仅适用于最后的textview。任何人都可以为我提供解决方案。我想并行两个textview。

  <TextView
        android:id="@+id/textMarqueName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:background="@android:color/black"
        android:duplicateParentState="true"
        android:ellipsize="marquee"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingBottom="0dp"
        android:paddingTop="0dp"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="@string/textMarque"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="#FFFFFF" >

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

    <TextView
        android:id="@+id/textMarqueDiff"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/textMarqueName"
        android:background="@android:color/black"
        android:duplicateParentState="true"
        android:ellipsize="marquee"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingBottom="0dp"
        android:paddingTop="0dp"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="@string/textMarque"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="#FFFFFF" >

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