前言

通过url来获取bitmap 然后通过glide工具来加载bitmap 来实现图片点击放大
废话不多说，直接上代码

代码

String netPhoto = "xxx";//从网络加载缓存try {Glide.with(TakePhotoSurveyActivity.this).asBitmap().load(photoDesign).into(new CustomTarget<Bitmap>() {@SuppressLint("ClickableViewAccessibility")@Overridepublic void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {runOnUiThread(() -> bigImageLoaderLocal(resource));}@Overridepublic void onLoadCleared(@Nullable Drawable placeholder) {}});} catch (Exception e) {e.printStackTrace();
}

点击放大图片

    /*** 点击放大本地图片** @param bitmap bitmap*/private void bigImageLoaderLocal(Bitmap bitmap) {Dialog dialog = new Dialog(this);ImageView image = new ImageView(this);image.setImageBitmap(bitmap);dialog.setContentView(image);//将dialog周围的白块设置为透明if (dialog.getWindow() != null) {dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);//显示dialog.show();//点击图片取消image.setOnClickListener(v -> dialog.cancel());}}
