onActivityResult 应该是这样的

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
    ImageCropFunction();

} else if (requestCode == 2) {

    if (data != null) {

        uri = data.getData();

        ImageCropFunction();
    }
} else if (requestCode == 1) {

    if (data != null) {
ImageCropFunction(); 
try {

            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
            Bundle bundle = data.getExtras();

            bitmap =bundle.getParcelable("data");
            Imageview.setImageBitmap(bitmap);
            Imageview.setVisibility(View.VISIBLE);
            Name.setVisibility(View.VISIBLE);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

我刚删除了一个额外的位图

Bitmap bitmap =bundle.getParcelable("data");

应该只是这样，

bitmap =bundle.getParcelable("data");

裁剪图像并将其保存到mysqldatabse中
