Android学习笔记-获取屏幕大小

方法
做屏幕适配时,有时需要知道屏幕的宽高,我们一般采用Android提供的“DisplayMetrics”类来获取相应信息。
先看下DisplayMetrics的简单使用方法示例:
package com.example.isweixin.window;

import android.util.DisplayMetrics;

import android.widget.PopupWindow;

import android.app.Activity;

import android.util.Log;



public class MenuWindowAdd extends PopupWindow {

	public MenuWindowAdd(final Activity context) {

		DisplayMetrics dm = new DisplayMetrics();

		context.getWindowManager().getDefaultDisplay().getMetrics(dm);



		int iWidth  = dm.widthPixels;

		int iHeight = dm.heightPixels;

		Log.e("motadou", iWidth + "," + iHeight);

	}

}

通过DisplayMetrics类我们可以获得显示设备的这些信息:
另外一种获取屏幕宽高的大小:
今天使用Display获取屏幕的宽和高时出现下面的提示: Display dp=getWindowManager().getDefaultDisplay(); int Height=dp.getHeight(); ---->The method getHeight() from the type Display is deprecated int Width=dp.getWidth(); ---->The method getWidth() from the type Display is deprecated 复制代码 官方解释: int getHeight() This method was deprecated in API level 13. Use getSize(Point) instead. int getWidth() This method was deprecated in API level 13. Use getSize(Point) instead. http://developer.android.com/reference/android/view/Display.html 复制代码 复制代码 替代的方法: DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); SCREEN_WIDTH = dm.widthPixels; SCREEN_HEIGHT = dm.heightPixels; 解析heightPixels和widthPixels: public int heightPixels The absolute height of the display in pixels. public int widthPixels The absolute width of the display in pixels.
