GridView row height

问题:

I have a GridView that displays images, which are, unfortunately, of different sizes. They are shown in between two lines of text:

text1.1                text1.2
ImageView(IMAGE1)      ImageView(IMAGE2)
text2.1                text2.2

text3.1
ImageView(IMAGE3)
text4.1

etc....

If IMAGE1 is the same height as IMAGE2, everything is fine, but if IMAGE1 is longer than IMAGE2, text2.1 will run into text3.1 (padding doesn't seem to help much, as there's too much of it when images are of the same height).

I know there's a way to stretch the images in the ImageView so they are the same height, but is it possible to keep images as is and set the row height somehow?

回答1:

You are in control over your row heights, by virtue of what you put in them. Since your cells appear to have more than one widget, they are presumably wrapped in a LinearLayout or something. Set your LinearLayouts to be some specific height, and the rows will all be that height.

Personally, I think you should be resizing your images if you are going to have text above and below each image on a per-cell basis.

回答2:

Use drawable as background on Layout that is your grid cell and define that drawable with:

<size android:height="<some height>" />

For example:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
<solid android:color="#ffffff"/>
<size android:height="60dip" />
</shape>

Here is an alternative solution that pre-measures items and sets the height of each cell to the max height in that row.
