安卓與滾動視圖和圖像調整大小的問題

Question

這是我使用的main.xml，myImage_Main和myImage_Main2中的兩個圖像混亂了。
有沒有辦法將android：layout_width設置爲位圖的大小？或者我只是將它設置爲500px，這大約是屏幕的大小？

實例我想要什麼：

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

只需使用wrap_content所有這些的。當佈局在setContentView(R.layout.your_layout)中膨脹時，它將確定顯示其所有子視圖所需的寬度的確切數量。但是，您需要設置scaleType="none"。我不完全確定你想要完成什麼，所以如果我誤解了這個問題，請澄清一下。
