Crop Image tutorial 2

I want it to be something like this.

I want it be something like this

editButton.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent goEdit;
            goEdit = new Intent(PreviewActivity.this, CropImage.class);
            goEdit.putExtra("image-path", path);
            goEdit.putExtra("scale", true);
            goEdit.putExtra("fileName", nameFromPath);
            //finish();
            checkEdit = true;
            startActivityForResult(goEdit,0);

        }
});

EDIT I use this button listener to call into the cropImage file by calling to the class CropImage activity. This is a custom intent not the crop feature inside android but I think is the copy of it so that make it support for all versions but when I call into it the selected area isnt brighten and I donno where is the problem can anyone guide me? Thanks This is the library I'm using drioid4you crop image


Solution

  • Can you use default android Crop functionality?

    Here is my code

    private void performCrop(Uri picUri) {
        try {
            Intent cropIntent = new Intent("com.android.camera.action.CROP");
            // indicate image type and Uri
            cropIntent.setDataAndType(picUri, "image/*");
            // set crop properties here
            cropIntent.putExtra("crop", true);
            // indicate aspect of desired crop
            cropIntent.putExtra("aspectX", 1);
            cropIntent.putExtra("aspectY", 1);
            // indicate output X and Y
            cropIntent.putExtra("outputX", 128);
            cropIntent.putExtra("outputY", 128);
            // retrieve data on return
            cropIntent.putExtra("return-data", true);
            // start the activity - we handle returning in onActivityResult
            startActivityForResult(cropIntent, PIC_CROP);
        }
        // respond to users whose devices do not support the crop action
        catch (ActivityNotFoundException anfe) {
            // display an error message
            String errorMessage = "Whoops - your device doesn't support the crop action!";
            Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
            toast.show();
        }
    }
    

    declare:

    final int PIC_CROP = 1;
    

    at top.

    In onActivity result method, writ following code:

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
    
        if (requestCode == PIC_CROP) {
            if (data != null) {
                // get the returned data
                Bundle extras = data.getExtras();
                // get the cropped bitmap
                Bitmap selectedBitmap = extras.getParcelable("data");
    
                imgView.setImageBitmap(selectedBitmap);
            }
        }
    }
    

    It is pretty easy for me to implement and also shows darken areas.
