Glide加载Gif时候设置Gif的大小

        Glide.with(context)
                .asBitmap()
                .load(uri)
                .into(new SimpleTarget<Bitmap>(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL) {
                    @Override
                    public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                        int width = resource.getWidth();
                        int height = resource.getHeight();
                        // 设置想要的大小
                        int newWidth = ScreenUtils.getScreenWidth(context);
                        int newHeight = newWidth * height / width;
                        // 计算缩放比例
                        float scaleWidth = ((float) newWidth) / width;
                        float scaleHeight = ((float) newHeight) / height;
                        // 取得想要缩放的matrix参数
                        Matrix matrix = new Matrix();
                        matrix.postScale(scaleWidth, scaleHeight);
                        // 得到新的图片
                        resource = Bitmap.createBitmap(resource, 0, 0, width, height, matrix, true);
                        gifImageView.setImageBitmap(resource);
                    }
                });



    Glide.with(getApplicationContext())
            .load(R.mipmap.app_center_add)
            .diskCacheStrategy(DiskCacheStrategy.NONE)

        public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
            Toast.makeText(WelcomActivity.this, getString(R.string.nettip), Toast.LENGTH_SHORT).show();

// 本地sdk
return false;
}

        @Override

            new Handler().postDelayed(new Runnable() {

                }
            },2000);
            return false;
