从画廊中选择的裁剪图像

Question

我希望用户从图库中选择图像，裁剪并在图像视图中进行设置。

图像被选中，Android内置的裁剪功能打开了。一切都很好，在这里。但是当我点击保存（裁剪所需的部分后）时，我没有返回到活动，但应用程序刚刚关闭而没有任何错误。

以下是我的代码：

public void changeAvatar(View view) {
    Intent pickFromGallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(pickFromGallery, OpenGallery);
}

这是onActivityResult：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == OpenGallery && resultCode == RESULT_OK) {
        pickedImage = data.getData();
        String[] filePath = {MediaStore.Images.Media.DATA};
        Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
        cursor.moveToFirst();
        cursor.close();
        String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));
        thumbnial = BitmapFactory.decodeFile(imagePath);
        performCrop();
       // Picasso.with(this).load(imagePath).centerCrop().resize(280,240).into(pro_pic);
       // pro_pic.setImageBitmap(BitmapFactory.decodeFile(imagePath));

    }
    if (requestCode == PIC_CROP && resultCode == RESULT_OK){
        Bundle extras = data.getExtras();
        thumbnial = extras.getParcelable("data");
        pro_pic.setImageBitmap(thumbnial);
    }
}

这是performCrop方法：

private void performCrop() {
    Intent cropIntent = new Intent("com.android.camera.action.CROP");
    cropIntent.setDataAndType(pickedImage, "image/*");
    //set crop properties
    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", 280);
    cropIntent.putExtra("outputY", 240);
    //retrieve data on return
    cropIntent.putExtra("return-data", true);
    //start the activity - we handle returning in onActivityResult
    startActivityForResult(cropIntent, PIC_CROP);
}
