安卓。 SetCompoundDrawables 不工作

Question

我尝试将 right-drawable 设置为 TextView(在 ListView 的标题中)。我正在设置界限，但这没有帮助。 setDrawablesWithInstrinctBounds() 工作正常。

代码如下:

private View getHeaderView() {
    final LayoutInflater inflater = getActivity().getLayoutInflater();
    final View view = inflater.inflate(R.layout.legislation_article_list_header, null, false);
    final TextView textView = (TextView) view.findViewById(R.id.sEdition);
    headerSpinner = textView;

    final Drawable d = getActivity().getResources().getDrawable(R.drawable.spinner_arrow_down);
    d.setBounds(new Rect(0, 0, headerSpinner.getHeight(), headerSpinner.getHeight()));
    headerSpinner.setCompoundDrawables(null, null, d, null);

    textView.setOnClickListener(new View.OnClickListener() {

       .............

        }
    });
    return view;
}

问题是什么？

Answer 1

试试这个:

Drawable d = getActivity().getResources().getDrawable(R.drawable.spinner_arrow_down);
d.setBounds(new Rect(0, 0, headerSpinner.getHeight(), headerSpinner.getHeight()));
textView.setCompoundDrawablesWithIntrinsicBounds( d , null, null, null);

或

textView.setCompoundDrawablesWithIntrinsicBounds( R.drawable.smiley, 0, 0, 0);
