GridView 自动调整图像 [英] GridView auto fit images

问题描述

我试图在 GridView 中显示图像并自动设置列，到目前为止我不得不手动设置列数，这不是我想要做的，因为这会影响图像的大小不同尺寸的屏幕.我试过将它设置为 auto_fit 但它只在屏幕中间显示 2 列.这就是我想要实现的:(每个红色方块代表一个图像)

im trying to get images displayed in a GridView and get the columns automatically set, so far I've had to manually set the number of columns which is not what i want to do as this will affect how big the images are on different sized screens. I ahve tried setting it to auto_fit but it only displays 2 columns in the middle of the screen. This is what im trying to achieve: (Each red square represents an image)

然后当转向横向模式时，我希望列自动适应，以便它全部均匀.任何帮助将不胜感激，谢谢:)

then when turned to landscape mode i want the columns to auto fit so that its all even. Any help would be much appreciated, thank you :)

推荐答案

使用 GridView 属性进行实验，特别是 android:numColumns="auto_fit" 和 android:stretchMode.以下对我有用:

Experiment with the GridView attributes, specifically android:numColumns="auto_fit" and android:stretchMode. The following works for me:

<GridView 
    android:id="@+id/myGrid"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:numColumns="auto_fit"
    android:columnWidth="60dp"
    android:stretchMode="columnWidth"    
    android:gravity="center"
/>
