Is there any difference between Button with image, ImageButton and clickable ImageView?

推荐答案

这大概只能覆盖的不同部分，这将有助于真正看的Andr​​oid源代码树，看看到底发生了什么事情。

This probably only covers part of the differences, it would be helpful to actually look at the Android Source tree to see exactly what's going on.

ImageButtons有推的状态，其中一个可点击的图片没有。 你也不能说的setText为ImageButton的，你可以用一个常规的按钮。

ImageButtons has push states, where as a clickable image does not. You also can't call setText for ImageButton, you can with a regular button.

他们都从视野中获得，但看着下面的延伸链可能会有点帮助。

They all derive from view, but looking at the following extends chain may help a little.

java.lang.Object
↳ android.view.View
   ↳ android.widget.ImageView
       ↳ android.widget.ImageButton

与

java.lang.Object
↳ android.view.View
   ↳ android.widget.TextView
       ↳ android.widget.Button
