Android(安卓)RecycerView 中根据图片大小自适应控件大小的实现

问题

recyclerView中 item有ImageView，ImageView大小根据图片大小而改变大小

解决方案

GlideApp.with(mContext)                        .asBitmap()                        .load(item.getContent())                        .error(R.drawable.default_bg)                        .diskCacheStrategy(DiskCacheStrategy.ALL)                        .into(new SimpleTarget() {                            @Override                            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {                                int widht = resource.getWidth();                                int height = resource.getHeight();                                if(widht>pic_max_width){                                    float multiple = ((float) widht)/pic_max_width+0.5f;                                    widht = (int) (widht/multiple);                                    height = (int) (height/multiple);                                }                                LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) img.getLayoutParams();                                params.width = widht;                                params.height = height;                                img.setLayoutParams(params);                                img.setImageBitmap(resource);                            }                        });

pic_max_width:

pic_max_width = DisplayUtils.getScreenWidth(this)-DisplayUtils.dip2px(this,50);

问题解决 50是ImageView的左右margin
