Question

这是我使用的main.xml，myImage_Main和myImage_Main2中的两个图像混乱了。
有没有办法将android：layout_width设置为位图的大小？或者我只是将它设置为500px，大约是屏幕的大小？

我想要的例子：

Scroll view -------------------------------
|
|               Image 1 Full Sized on Screen
|
|
|               Bottom of screen
___________________________________________
|              Not yet on screen, but  
|           Scroll down to see Image 2    |
|
|

Answer 1

只需使用wrap_content即可。当布局在setContentView(R.layout.your_layout)中膨胀时，它将确定显示其所有子视图所需的确切宽度。但是，您需要设置scaleType="none"。我不完全确定你想要完成什么，所以如果我误解了这个问题，请澄清。
