Question

我有一个包含CardView的布局。我添加了Scrollview，我在Textview中添加了android:scrollable=vertical，我添加了mytxtview.setMovementMethod(new ScrollingMovementMethod());

没有工作！我在textview中有一个非常大的文本，它不适合屏幕，我看不到整个文本，请帮助我。这是我的布局，请帮帮我。

编辑：Java代码

public class Fragment5 extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        ViewGroup rootView = (ViewGroup) inflater.inflate(
                R.layout.fragmentdescrip5, container, false);


        TextView mytxtview = (TextView) rootView.findViewById(R.id.textViewNamefrag5);
        mytxtview.setMovementMethod(new ScrollingMovementMethod());



        return rootView;
    }

}

删除maxLines="25";这会将文本的长度限制为25行。

在Cardview中显示文本，不适合屏幕
