我有一个片段中的这段代码

public class TestOne extends Fragment {

    View view = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);

      LayoutInflater inflater2 = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater2.inflate(R.layout.testone, null);

        Toast.makeText(getActivity(), "Rotate fragment", Toast.LENGTH_SHORT).show();
    }

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

        Toast.makeText(getActivity(), "onCreate Fragment", Toast.LENGTH_SHORT).show();

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.testone, null);

        Toast.makeText(getActivity(), "onCreateView fragment", Toast.LENGTH_SHORT).show();

        return view;
    }

}

我想做的是,当我旋转手机时,我不想再次执行这些方法。但是我想再次调用xml布局,以加载layout-land文件夹的xml。

这段代码没有给出任何错误,只是不起作用并且不了解原因..

我真的对使用onConfiguratonChanged做到这一点很感兴趣

感谢您的帮助。

感谢致敬

最佳答案

onCreateView中创建FrameLayout-这是您fragmenView的容器。然后创建您的R.layout.testone并将其添加到frameLayout

onConfigurationChanged中清除FrameLayout,再次创建R.layout.testone并将其添加到frameLayout中。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
    frameLayout = new FrameLayout(getActivity());
    LayoutInflater inflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.testone, null);
    frameLayout .addView(view);
    return frameLayout;
}

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    frameLayout. removeAllViews();
    LayoutInflater inflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.testone, null);
    frameLayout .addView(view);
}

现在一切都将按您的意愿工作!
