Android在自定义控件时,经常需要获得屏幕的宽高,每次都要写,不妨直接把他封装成工具类,直接拿来用,废话不说,直接上代码

    /** 
     *  
     */  
    package com.example.customview;  
      
    import android.content.Context;  
    import android.util.DisplayMetrics;  
    import android.view.WindowManager;  
      
    /** 
     * 获取手机屏幕大小 
     * @author  
     * 
     */  
    public class MeasureUtil {  
          
        /** 
         * 宽 
         * @return 
         */  
        public static int getWidth(Context context){  
            WindowManager wm=(WindowManager) context.getSystemService(Context.WINDOW_SERVICE);  
            DisplayMetrics outMetrics = new DisplayMetrics();  
            wm.getDefaultDisplay().getMetrics(outMetrics);  
            return outMetrics.widthPixels;  
        }  
          
        /** 
         * 高 
         * @return 
         */  
        public static int getHeight(Context context){  
            WindowManager wm=(WindowManager) context.getSystemService(Context.WINDOW_SERVICE);  
            DisplayMetrics outMetrics = new DisplayMetrics();  
            wm.getDefaultDisplay().getMetrics(outMetrics);  
            return outMetrics.heightPixels;  
        }  
      
    }
