屏幕适配之px转dip

 1 import android.content.Context;
 2 
 3 public class DensityUtils {
 4     
 5     /**
 6      * 把PX转化为dip
 7      * @param context
 8      * @param px
 9      * @return
10      */
11     public static int px2dip(Context context,float px){
12         
13         float density = context.getResources().getDisplayMetrics().density;
14         int dip = (int) (px * density);
15         
16         return dip;
17     }
18 }

mPopupWindow = new PopupWindow(contentView, ViewGroup.LayoutParams.WRAP_CONTENT,DensityUtils.px2dip(getApplicationContext(), 70));将70的像素转换为dip

(上面公式参考google官方文档)
