When customizing controls in Android, you often need to get the width and height of the screen. You have to write it every time. You might as well encapsulate it into a tool class and use it directly. Don’t talk nonsense and just write the code
/** * */ 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; } }
