如何固定裁剪突出显示视图的高度，而不是使用上载的图像进行更改？

Question

I am using the following sample code, https://github.com/mklimek/android-crop/tree/newfeature_fied_size_crop . It is giving the fixed size cropping view(ie, HighlightView). But the problem is this highlightView is fixed depends on Uploaded image. Below are the screen shots with two different size uploaded images.

I used below lines of code to fix the size of the HighlightView:

 private void beginCrop(Uri source) {
    Uri outputUri = Uri.fromFile(new File(getCacheDir(), "cropped"));
    new Crop(source).output(outputUri).asRectangle().withFixedSize(100, 210).start(this);
 }

withFixedSize() method is used to fix the size of the cropped area , we cannot resize that view if we use this method, that is fine. But That cropped area should be fixed with width=100, height=210,It should not change depends the uploaded image.

Big size uploaded image has a small size of crop view (ie, HighlightView):

Small size uploaded image has a large size of crop view (ie, HighlightView):

My requirement is I have to fix the size of cropped area, I should not resize that. I searched in google world. But I didn't found solution.

Please help me on this.

Crop

Crop.of(inputUri, outputUri).asSquare().start(activity)

Listen for the result of the crop (see example project if you want to do some error handling):

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent result) {
    if (requestCode == Crop.REQUEST_CROP && resultCode == RESULT_OK) {
        doSomethingWithCroppedImage(outputUri);
    }
}

Some attributes are provided to customise the crop screen. See the example project theme.

Pick

The library provides a utility method to start an image picker:

Crop.pickImage(activity)

Dependency

The AAR is published on Maven Central:

compile 'com.soundcloud.android:android-crop:1.0.1@aar'

Java code :

public class MainActivity extends Activity {

    private ImageView resultView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        resultView = (ImageView) findViewById(R.id.result_image);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.action_select) {
            resultView.setImageDrawable(null);
            Crop.pickImage(this);
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent result) {
        if (requestCode == Crop.REQUEST_PICK && resultCode == RESULT_OK) {
            beginCrop(result.getData());
        } else if (requestCode == Crop.REQUEST_CROP) {
            handleCrop(resultCode, result);
        }
    }

    private void beginCrop(Uri source) {
        Uri destination = Uri.fromFile(new File(getCacheDir(), "cropped"));
        Crop.of(source, destination).asSquare().start(this);
    }

    private void handleCrop(int resultCode, Intent result) {
        if (resultCode == RESULT_OK) {
            resultView.setImageURI(Crop.getOutput(result));
        } else if (resultCode == Crop.RESULT_ERROR) {
            Toast.makeText(this, Crop.getError(result).getMessage(), Toast.LENGTH_SHORT).show();
        }
    }

}

Output :
