如何更改片段文本？

Question

這是我的Fragment類，我在xmlfile中有一個textView

如何通過setText更改TextView ？

public class Frist extends Fragment   {

    TextView text;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.activity_frist, container, false);
        TextView t = (TextView) this.getView().findViewById(R.id.textView1);
        t.setText("SOME TEXT");

        return rootView;

    }
}

Answer 1

代替

TextView t = (TextView) this.getView().findViewById(R.id.textView1);

您應該在膨脹的視圖上調用findViewById ：

TextView t = (TextView) rootView.findViewById(R.id.textView1);
