在选项卡上显示库选择使用库的android

Question

我目前有两个显示相机和图库的标签，例如Instagram app.tabs是片段。换句话说，我有一个viewpager和两个标签，并在标签片段，我想显示相机和画廊。我正在使用Mattise库来显示图库。
我的问题是在点击图库标签时显示图库。我当前的代码只是在我点击选择图片按钮时显示图库，当我点击图库标签时不显示。

此片段代码：

public class GalleryFragment extends Fragment {

private static final int REQUEST_CODE_CHOOSE = 1001;
private static final int RESULT_OK = 1002;
private View view;
private static final int reqCode = 1000;

public static GalleryFragment newInstance() {
    GalleryFragment galleryFragment = new GalleryFragment();
    return galleryFragment;
}


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.fragment_gallery, container, false);
    Matisse.from(GalleryFragment.this)
            .choose(MimeType.allOf())
            .countable(true)
            .capture(false)
            .captureStrategy(
                    new CaptureStrategy(true, "com.zhihu.matisse.sample.fileprovider"))
            .maxSelectable(9)
            .gridExpectedSize(
                    getResources().getDimensionPixelSize(R.dimen.grid_expected_size))
            .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
            .thumbnailScale(0.85f)
            .imageEngine(new PicassoEngine())
            .forResult(REQUEST_CODE_CHOOSE);

    return view;
}

List<Uri> mSelected;

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_CHOOSE && resultCode == RESULT_OK) {
        mSelected = Matisse.obtainResult(data);
        Log.d("Matisse", "mSelected: " + mSelected);
    }
}

}

此代码在我开始活动时显示图库，在点击图库标签时不显示...
