如何在Android中增加ScrollView的高度? [英] How to increase ScrollView height in Android?

问题描述

你好朋友，

我正在 ScrollView 中使用 GridView 来显示图像.在GridView中，我动态地添加了16张图像，但是 ScrollView 不能显示全部16张图像(请参见屏幕截图).

I am using GridView inside a ScrollView for displaying images. In the GridView I have 16 images which were dynamically added, but the ScrollView does not display all 16 images (see screenshot).

我希望 ScrollView 显示整个 GridView ，有人知道我该如何解决?

I want the ScrollView to display the whole GridView, does anybody know how I can fix this?

谢谢.

推荐答案

在XML布局中使用属性 android:fillViewport ="true" 或使用方法 setFillViewport(true)用Java代码编写.

Use attribute android:fillViewport="true" in XML layout or use method setFillViewport(true) in Java code.
