Question

我在滚动视图中使用了两个可扩展的高度网格视图。我面临这个问题。当在文本视图中设置动态文本时，网格视图显示如下图像。如何解决此问题？。在textview中设置静态文本时查看perfect.but使用动态我有一个问题。我可以解决它吗？

使用这个：

<LinearLayout
    android:id="@+id/dashrowlin"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/dashImg"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_gravity="center"
        android:layout_marginTop="15dp"
        />

    <TextView
        android:id="@+id/dashName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="5dp"
        android:gravity="center"
        android:padding="7dp"
        android:maxLines="2"
        android:lines="2"
        android:ellipsize="end"
