WheelView设置焦点监听无效

[CronZhu]

移除WheelView的根布局和父布局的焦之后，再给WheelView设置setFocusable(true)、setFocusableInTouchMode(true)、setOnFocusChangeListener，但是onFocusChange中依旧监听不到焦点事件。 代码如下： // 年 wv_year = (WheelView) view.findViewById(R.id.year); wv_year.setAdapter(new ArrayWheelAdapter(ChinaDate.getYears(startYear, endYear)));// 设置"年"的显示数据 wv_year.setLabel("");// 添加文字 wv_year.setCurrentItem(year - startYear);// 初始化时显示的数据 wv_year.setGravity(gravity); wv_year.setClickable(true); wv_year.setFocusable(true); wv_year.setFocusableInTouchMode(true); wv_year.setOnFocusChangeListener(new View.OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { Log.i(TAG," onFocusChange "+hasFocus); } });
