Android(安卓)获取drawable中图片的高度宽度

1.定义一个ImageData类如下：

package com.example.vidarecyclerviewstagger;public class ImageData {    private int resourceId;    private int height;    private int width;    public ImageData(int resourceId,int height,int width){        this.resourceId = resourceId;        this.height = height;        this.width = width;    }    public int getResourceId() {        return resourceId;    }    public void setResourceId(int resourceId) {        this.resourceId = resourceId;    }    public int getHeight() {        return height;    }    public void setHeight(int height) {        this.height = height;    }    public int getWidth() {        return width;    }    public void setWidth(int width) {        this.width = width;    }}

2.在drawable中放置一些图片：

private static int[] imgRes = new int[]{R.drawable.img1,R.drawable.img2,R.drawable.img3,R.drawable.img4,        R.drawable.img5,R.drawable.img6,R.drawable.img7,R.drawable.img8,        R.drawable.img9,R.drawable.img10,R.drawable.img11,R.drawable.img12,        R.drawable.img13,R.drawable.img14,R.drawable.img15,R.drawable.img16};

3.获取每个图片的高度宽度并保存数据到mData中：

private ArrayList<ImageData> mData = new ArrayList<>();public void InitData(){    for(int i = 0;i < imgRes.length;i++){        BitmapFactory.Options options = new BitmapFactory.Options();        BitmapFactory.decodeResource(getResources(),imgRes[i],options);        //获取图片的宽高        int height = options.outHeight;        int width = options.outWidth;        Log.i("YYYY","图片的宽度:"+width+"图片的高度:"+height);        ImageData imgData = new ImageData(imgRes[i],height,width);        mData.add(imgData);    }}

关键代码就这么几句：

BitmapFactory.Options options = new BitmapFactory.Options();BitmapFactory.decodeResource(getResources(),imgRes[i],options);//获取图片的宽高int height = options.outHeight;int width = options.outWidth;
