Glide使用

来源：互联网发布：project tango 淘宝编辑：程序博客网时间：2024/04/29 17:01

compile 'com.github.bumptech.glide:glide:3.7.0'//图形处理框架，可以不加compile 'jp.wasabeef:glide-transformations:2.0.1'    // If you want to use the GPU Filters    compile 'jp.co.cyberagent.android.gpuimage:gpuimage-library:1.3.0'

2.使用

final ImageView imageview= (ImageView) findViewById(R.id.my_image_view);        Glide.with(this).load("http://attach.bbs.miui.com/forum/201502/08/021410qwvwbpdkiasdhwha.jpg")//                .asGif()        .diskCacheStrategy(DiskCacheStrategy.SOURCE)//                .placeholder(R.mipmap.ic_launcher)//                .transform(new GlideCircleTransform(MainActivity.this))        .bitmapTransform(new CropCircleTransformation(MainActivity.this))//                .transform(new RoundedCornersTransformation(this,30,0, RoundedCornersTransformation.CornerType.ALL))                .into(imageview);

asgif（）和不asgif（）区别：
asgif（）就不可以调用.bitmapTransform 方法。但是有一个transfrom方法。也就是说你加上asgif你就不可以使用上面我提到的那个图形处理框架。而且不加gif也可以显示gif，而且可以用上面的框架圆角显示

3.当然你可以自己写处理图片的逻辑如下：

//这会让图片圆角显示package cn.xinyu.com.myapplication;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapShader;import android.graphics.Canvas;import android.graphics.Paint;import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;/** * Created by Administrator on 2016/6/2. */public class GlideCircleTransform extends BitmapTransformation {    public GlideCircleTransform(Context context) {        super(context);    }    @Override    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {        return circleCrop(pool, toTransform);    }    private Bitmap circleCrop(BitmapPool pool, Bitmap toTransform) {        if (toTransform == null) return null;        int size = Math.min(toTransform.getWidth(), toTransform.getHeight());        int x = (toTransform.getWidth() - size) / 2;        int y = (toTransform.getHeight() - size) / 2;        // TODO this could be acquired from the pool too        Bitmap squared = Bitmap.createBitmap(toTransform, x, y, size, size);        Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);        if (result == null) {            result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);        }        Canvas canvas = new Canvas(result);        Paint paint = new Paint();        paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));        paint.setAntiAlias(true);        float r = size / 2f;        canvas.drawCircle(r, r, r, paint);        return result;    }    @Override    public String getId() {        return getClass().getName();    }}

然后使用的时候：

 Glide.with(this).load("http://attach.bbs.miui.com/forum/201502/08/021410qwvwbpdkiasdhwha.jpg") .transform(new GlideCircleTransform(MainActivity.this))

4.gif加载慢解决方法

.asGif()        .diskCacheStrategy(DiskCacheStrategy.SOURCE)
