图片加载控件glide

 

 

基本用法
        //（1）加载网络图片
        tvGlide1.setText("（1）加载网络图片");
        Glide.with(this).load("http://img1.imgtn.bdimg.com/it/u=2615772929,948758168&fm=21&gp=0.jpg").into(ivGlide1);

        //（2）加载资源图片
        tvGlide2.setText("（2）加载资源图片");
        Glide.with(this).load(R.drawable.atguigu_logo).into(ivGlide2);

        //（3）加载本地图片
        tvGlide3.setText("（3）加载本地图片");
        String path = Environment.getExternalStorageDirectory() + "/meinv1.jpg";
        File file = new File(path);
        Uri uri = Uri.fromFile(file);
        Glide.with(this).load(uri).into(ivGlide3);

        // （4）加载网络gif
        tvGlide4.setText("（4）加载网络gif");
        String gifUrl = "http://b.hiphotos.baidu.com/zhidao/pic/item/faedab64034f78f066abccc57b310a55b3191c67.jpg";
        Glide.with(this).load(gifUrl).placeholder(R.mipmap.ic_launcher).into(ivGlide4);

        // （5）加载资源gif
        tvGlide5.setText("（5）加载资源gif");
        Glide.with(this).load(R.drawable.loading).asGif().placeholder(R.mipmap.ic_launcher).into(ivGlide5);

        //（6）加载本地gif
        tvGlide6.setText("（6）加载本地gif");
        String gifPath = Environment.getExternalStorageDirectory() + "/meinv2.jpg";
        File gifFile = new File(gifPath);
        Glide.with(this).load(gifFile).placeholder(R.mipmap.ic_launcher).into(ivGlide6);

        //（7）加载本地小视频和快照
        tvGlide7.setText("（7）加载本地小视频和快照");
        String videoPath = Environment.getExternalStorageDirectory() + "/video.mp4";
        File videoFile = new File(videoPath);
        Glide.with(this).load(Uri.fromFile(videoFile)).placeholder(R.mipmap.ic_launcher).into(ivGlide7);

        //（8）设置缩略图比例,然后，先加载缩略图，再加载原图
        tvGlide8.setText("（8）设置缩略图比例,然后，先加载缩略图，再加载原图");
        String urlPath = Environment.getExternalStorageDirectory() + "/meinv1.jpg";
        Glide.with(this).load(new File(urlPath)).thumbnail(0.1f).centerCrop().placeholder(R.mipmap.ic_launcher).into(ivGlide8);

        //（9）先建立一个缩略图对象，然后，先加载缩略图，再加载原图
        tvGlide9.setText("（9）先建立一个缩略图对象，然后，先加载缩略图，再加载原图");
        DrawableRequestBuilder thumbnailRequest = Glide.with(this).load(new File(urlPath));
        Glide.with(this).load(Uri.fromFile(videoFile)).thumbnail(thumbnailRequest).centerCrop().placeholder(R.mipmap.ic_launcher).into(ivGlide9);
