Cropping Image in Android (Crop Intent)

问题

I used this code to use android's built in image crop tools. My code is the following

 public void takePicture(){
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null){
        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
        takePictureIntent.putExtra("crop", "true");
        takePictureIntent.putExtra("aspectX", 0);
        takePictureIntent.putExtra("aspectY", 0);
        takePictureIntent.putExtra("outputX", 200);
        takePictureIntent.putExtra("outputY", 150);
        takePictureIntent.putExtra("return-data", true);

        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    }

}

protected void onActivityResult(int requestCode, int resultCode, Intent data){
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Bitmap imageBitmap = (Bitmap) extras.get("data");
        imageViewImage.setImageBitmap(imageBitmap);

    }
}

takePicture is called inside a click listener for a Button. What is done is I can open android camera take the picture and when hitting save the image is saved on my imageView. But no cropping activity appears, plus the image on imageView looks awfull. The quality is like it's pixelated. Am I doing something wrong? I used a Samsung galaxy tab 3 to test my app

EDIT using the answer bellow...Stil not working

 protected void onActivityResult(int requestCode, int resultCode, Intent data){
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Log.d("onActivityResult", "Inside on activity for result");
        Bitmap imageBitmap = (Bitmap) extras.get("data");
        imageViewImage.setImageBitmap(imageBitmap);
        fileUri = getImageUri(this, imageBitmap);χ
        cropImage();
    }else if (requestCode == REQUEST_IMAGE_CROP && resultCode == RESULT_OK){
        Bundle extras = data.getExtras();
        Bitmap imageBitmap = (Bitmap)extras.get("data");
        imageViewImage.setImageBitmap(imageBitmap);


    }
}

 public void takePicture(){
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null){

        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    }

}

 public void cropImage() {
    try {

        Intent cropIntent = new Intent("com.android.camera.action.CROP");

        cropIntent.setDataAndType(fileUri, "image/*");
        cropIntent.putExtra("crop", "true");
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        cropIntent.putExtra("return-data", true);
        startActivityForResult(cropIntent, REQUEST_IMAGE_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();
    }
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

You can try this.

private void doCrop(Uri picUri) {
    try {

        Intent cropIntent = new Intent("com.android.camera.action.CROP");

        cropIntent.setDataAndType(picUri, "image/*");           
        cropIntent.putExtra("crop", "true");           
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);           
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);           
        cropIntent.putExtra("return-data", true);
        startActivityForResult(cropIntent, CROP_PIC_REQUEST_CODE);
    }
    // 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();
    }
}

Get Uri from bitmap

public Uri getImageUri(Context inContext, Bitmap inImage) {
  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
  String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
  return Uri.parse(path);
}

Declare

final int CROP_PIC_REQUEST_CODE = 1;

Than simply

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == CROP_PIC_REQUEST_CODE) {
        if (data != null) {
            Bundle extras = data.getExtras();
            Bitmap bitmap= extras.getParcelable("data");
            yourImageView.setImageBitmap(bitmap);
        }
    }

}
