如何在加载到ImageView之前调整图像大小以避免OOM问题 [英] How to resize image before loading to ImageView to avoid OOM issues

问题描述

从图库/照片中选择后，如何在加载到imageview之前调整图像大小?否则，大图像会导致OOM问题.

How can i resize image before loading to imageview after selecting from gallery/photos?. Otherwise large images are causing OOM issues.

SelectImageGallery.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Image From Gallery"), 1);
    }
}

Uri uri = I.getData();
    try {
        bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
        imageView.setImageBitmap(bitmap);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

推荐答案

对于那些将来可能需要使用它的人，我终于使用滑行解决了它，如下所示. 选择意图

I finally made it to resolve it using glide as follows for those who might need it in future. Selecting Intent

SelectImageGallery1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Image1 From Gallery"), 1);
    }
}

使用Glide将图像设置为Imageview

Setting Image to Imageview Using Glide

    @Override
    protected void onActivityResult(int RC, int RQC, Intent I) {
        super.onActivityResult(RC, RQC, I);
        if (RC == 1 && RQC == RESULT_OK && I != null && I.getData() != null) {
            Uri uri = I.getData();
            RequestOptions options = new RequestOptions()
                    .format(DecodeFormat.PREFER_RGB_565)
                    .placeholder(R.drawable.ic_launcher_background)
                    .error(R.drawable.ic_launcher_background);

            Glide.with(this)
                    .setDefaultRequestOptions(options)
                    .asBitmap()
                    .load(uri)
                    .centerInside()
                    .into(new CustomTarget<Bitmap>(512, 512) {
                        @Override
                        public void onResourceReady(@NonNull Bitmap bitmap1, @Nullable Transition<? super Bitmap> transition) {
                            imageView1.setImageBitmap(bitmap1);
                            MainActivity.this.bitmap1 = bitmap1;
                        }

                        @Override
                        public void onLoadCleared(@Nullable Drawable placeholder) {
                        }
                    });
        }
