解决方案

 显示mDisplay = activity.getWindowManager()getDefaultDisplay()。
最终诠释宽度= mDisplay.getWidth();
最终诠释身高= mDisplay.getHeight();
 

这样,您就可以得到屏幕的大小。

由于这个API是depricated在新的SDK版本,你可以用这个。

  DisplayMetrics displayMetrics = context.getResources()getDisplayMetrics()。
INT宽度= displayMetrics.widthPixels;
INT高= displayMetrics.heightPixels;
 

I am developing an app in which I have to make our app to fit for every device - for both tablet and android mobiles. Now I want to get the device height and width at runtime and implement it in my code so that my app works for both landscape and portrait.

解决方案
Display mDisplay = activity.getWindowManager().getDefaultDisplay();
final int width  = mDisplay.getWidth();
final int height = mDisplay.getHeight();

This way you can get the screen size.

Since this API is depricated in the new SDK versions you can use this.

DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
int width = displayMetrics.widthPixels;
int height = displayMetrics.heightPixels;

这篇关于如何获取设备的高度和宽度,在运行时?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
