Question

我正在尝试在图像前面放一个可能有4行文字的列表。图像不能正确地位于彼此之下，如果文本太长，它就会超出它的布局视图。并链接问题的图片; http://i.stack.imgur.com/zJwQg.png

如何解决图像对齐问题？我该怎么办？文本？

尝试使用具有以下属性的textview来保持屏幕内的线条。

  <TextView
        android:id="@+id/txt"
        android:paddingRight="50dp"
        android:layout_marginTop="24dp"
        android:textSize="20dp"
        android:layout_width="wrap_content"
        android:layout_height="50dp" 
        android:layout_weight="1"
        android:ellipsize="none"
        android:maxLines="100"
        android:scrollHorizontally="false"/>

然后，要在ImageView上叠加TextView，我建议用RelativeLayout替换TableLayout，如果没有指定其他属性，则将所有视图添加到左上角（允许视图堆叠在每个上面）其他）。 TableLayout不允许堆叠，只需将下一个视图添加到下一个可用空间即可。

listView的文字太多了？
