Question

首先，我是Android的编程新手。我想从图库中选择一个图像并将其上传。所有这一切都来自片段。问题是，当我从片段中选择图像时，返回到First Fragment，而不是调用它的片段。我搜索了这个，但选择图片后没有返回 onActivityResult 这https://inthecheesefactory.com/blog/how-to-fix-nested-fragment-onactivityresult-issue/en对我不起作用感谢

这是我的代码

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.e("fragment","fragment");
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            // Get the url from data
            selectedImageUri = data.getData();
            if (null != selectedImageUri) {
                // Get the path from the Uri
                String path = getPathFromURI(selectedImageUri);
                //Log.i(TAG, "Image Path : " + path);
                // Set the image in ImageView

            }
        }
    }
}

    void openImageChooser() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    getActivity().startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);

}

更新：已解决

除了调用startActivityForResult

之外，我都说过帖子

    void openImageChooser() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
}

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 122) {
        // Do your job

        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                // Get the url from data
                selectedImageUri = data.getData();
                if (null != selectedImageUri) {
                    // Get the path from the Uri
                    String path = getPathFromURI(selectedImageUri);
                    //Log.i(TAG, "Image Path : " + path);
                    // Set the image in ImageView
                    guardar();
                }
            }
        }
    }

}

阅读该帖子......

收到的所有结果都将在一个地方处理：片段放置的活动的onActivityResult。

因此，将onActivityResult移动到Activity。

有道理，因为Activity启动了intent，而不是Fragment本身。

getActivity().startActivityForResult

如何从Fragment中选择图像
