如何在Android Image Crop Screen中添加旋转按钮？

Question

I am using the below intent to crop the images selected from gallery or taken by camera:

Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");

However I need to add rotate buttons to that screen as well. Is there a way to do that?

Thanks in advance.

Answer 1

You can't do this. Because the Activity that you are talking about is not your Activity.

If you really need this, you will have to implement your own cropping functionality. Find the class corresponding to the AOSP cropping class and reuse it as you need it.

Answer 2

Try this: Set an onCLickListener on a normal button and perform your rotate function inside it. I don't really know how to rotate but the following could help:

Button rotateButton = (Button)findViewById(R.id.rotate_button);
rotateButton.setOnClickListener(new View.OnClickListener() 
        {
            public void onClick(View v) 
            {
                rotate();
            }
        });

protected void rotate()
    { 
       // see below links for rotating stuff.
    }

Try this , and this for rotating. Hope this helps.
