How to make the width of the image is full of the viewport.

[iboying]

1、This is my code:

detail_image = getViewById(R.id.detail_image);
detail_image.setMinimumScaleType(SCALE_TYPE_CUSTOM);
detail_image.setScaleX(1.0f);
...
Glide
    .with(context).load(imageUrl)
    .downloadOnly(new SimpleTarget<File>() {
          @Override
          public void onResourceReady(File resource, GlideAnimation<? super File> glideAnimation) {
                    detail_image.setImage(ImageSource.uri(Uri.fromFile(resource)), new ImageViewState(1.0f, new PointF(0, 0), 0));
});

2、This is my screenshot:

Hi, Dave:
This is a really great repository. And it is used for my project.
Yesterday, I have try setMinimumScaleType(SCALE_TYPE_CENTER_CROP) and fix my issue.

There is a new issue:
A short image can not fill the device width.

And this is the issue screenshot:

Use the Android Imageview and set android:scaleType="fitStart", it is like this:

Can the repository have some configurations like android:scaleType="fitStart"?

tks, @iboying ,setMinimumScaleType(SCALE_TYPE_CENTER_CROP) is a great method,but it is not fit my requirement,as you say, no attribude like fitStart

@iboying 你好，我遇到跟你一样的问题，请问你是如何解决的？能分享下吗？

I ended up doing it like this:

public void instantiateItem() {
    ....
    detail_image.setMinimumScaleType(SubsamplingScaleImageView.SCALE_TYPE_CUSTOM);
    detail_image.setMinScale(getFitWidthScale());
    ....
}
private float getFitWidthScale(){
    float viewWidth = App.getWindowWidth();
    return = viewWidth/getImageWidth();
}

private float getImageWidth(){
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(_file.getAbsolutePath(), options);
    return options.outWidth;
}

You could use setImage(ImageSource imageSource, ImageViewState state) method.

The next release will support setMinimumScaleType(SubsamplingScaleImageView.SCALE_TYPE_START), which will set the minimum scale so no black bars are visible and show the top of a tall image and the left of a wide image. Hopefully this meets everyone's needs.
