请问setWidth（INT像素）使用设备无关像素或物理像素为单位？ 例如，是否setWidth（100）设置视图的宽度为100骤降或100 PXS？

Does setWidth(int pixels) use device independent pixel or physical pixel as unit? For example, does setWidth(100) set the a view's width to 100 dips or 100 pxs?

感谢。

推荐答案

它使用像素，但我敢肯定你想知道如何使用骤降代替。答案是在TypedValue.applyDimension().下面是如何转换逢低code到PX的例子：

It uses pixels, but I'm sure you're wondering how to use dips instead. The answer is in TypedValue.applyDimension(). Here's an example of how to convert dips to px in code:

// Converts 14 dip into its equivalent px
Resources r = getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 14, r.getDisplayMetrics());
