Custom Android Image Crop

Question

i just want to share this piece of code that i wrote. I tried searching for a custom crop activity, but most of them leads to the default \"com.android.camera.action.CROP\"

Answer 1

thanks thehippo... but i've solved finding the view by the layout

Uri imageUri = getIntent().getExtras().getParcelable("path");
    b = (BitmapDrawable) BitmapDrawable.createFromPath(getRealPathFromURI(imageUri));
    myCropView = (CropView) findViewById(R.id.image_preview);
    myCropView.setBackground(b);

but now i can't handle the touch event. The rectangle stay still even if i touch the screen...

EDIT: ok, i've made it works. But now, the rectangle move only inside a smaller area, not in the entire image. I suppose that there's something wrong here

private boolean isInImageRange(PointF point) {
    // Get image matrix values and place them in an array
    float[] f = new float[9];
    getImageMatrix().getValues(f);

    // Calculate the scaled dimensions
    imageScaledWidth = Math.round(getBackground().getIntrinsicWidth() * f[Matrix.MSCALE_X]);
    imageScaledHeight = Math.round(getBackground().getIntrinsicHeight() * f[Matrix.MSCALE_Y]);

    return (point.x>=(center.x-(imageScaledWidth/2))&&point.x<=(center.x+(imageScaledWidth/2))&&point.y>=(center.y-(imageScaledHeight/2))&&point.y<=(center.y+(imageScaledHeight/2)))?true:false;
}

i've done a little change to make work the code: getBackground() instead of getDrawable

EDIT 2: OK ive got it, i was doing this in the wrong way. You're code is good. To set the image i was using the view.seBackground()...instead of view.setImageDrawable(). Now everything works. Maybe i will only check if it's possible to create a larger area that fires the scaling of the rectangle
