是否可以将可滚动的TextView添加到ListView？

Question

我有一个ListView,其中每一行都有一个固定的高度.
每行包含一些TextView旁边的行.
有时,我想要显示的文本太大,因此我想使其可滚动.
所以我添加了(基于在Android上可滚动的TextView)以下行到我的TextView

text.setMaxLines(5);
text.setVerticalScrollBarEnabled(true);
text.setMovementMethod(ScrollingMovementMethod.getInstance());

如果我单独使用TextView但是当我将TextView放在ListView中时,这种方法很好:
只要我进行垂直滚动,事件似乎被ListView使用.

关于如何使这项工作的任何建议？

下面添加了完整的(测试)活动(没有layout.xml)

public class TestScrollableTextView extends Activity
{ 
  protected void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);

    LinearLayout layout = new LinearLayout(this);
    //add a ListView
    ListView list = new ListView(this);
    layout.addView(list);
    list.setAdapter(new BaseAdapter()
    {

        @Override
        public View getView(int position, View convertView, ViewGroup parent)
        {
            TextView text = new TextView(TestScrollableTextView.this);
            String s = "";
            //add 10 lines of text, all but first are indented
            for (int i = 0; i < 10; i++)
            {
                if(i>0) s+="\t";
                s += "position "+position+"; line="+i+"\n";
            }
            text.setText(s);                
            text.setMaxLines(5);
            text.setVerticalScrollBarEnabled(true);
            text.setMovementMethod(ScrollingMovementMethod.getInstance());
            return text;
        }

        @Override
        public long getItemId(int position)
        {
            return 0;
        }

        @Override
        public Object getItem(int position)
        {

            return null;
        }

        @Override
        public int getCount()
        {
            return 20;
        }
    });

      setContentView(layout);

  }
}

getLineCount和getLineHieght并检查Text是否大于TextView.

如果你使用这个代码,可以通过触摸TextView以外的任何地方滚动listView,使用(boolean)isLarger = true.

text.setText(s);                
text.setMaxLines(100);
text.setVerticalScrollBarEnabled(true);
text.setMovementMethod(new ScrollingMovementMethod());
OnTouchListener listener = new OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
                boolean isLarger;

                isLarger = ((TextView) v).getLineCount()
                        * ((TextView) v).getLineHeight() > v.getHeight();
                if (event.getAction() == MotionEvent.ACTION_MOVE
                        && isLarger) {
                    v.getParent().requestDisallowInterceptTouchEvent(true);

                } else {
                    v.getParent().requestDisallowInterceptTouchEvent(false);

                }
                return false;
            }
        };

text.setOnTouchListener(listener);
