set WheelView items and init selected position
设置WheelView的数据和初始位置
set listener on WheelView that can get info when WheelView changed selected item.
对WheelView设置监听器,当WheelView 选中项改变时返回选中项的索引和值。
WheelView wva = (WheelView) findViewById(R.id.wheel_view);
wva.setItems(Arrays.asList(PLANETS),1);//init selected position is 1 初始选中位置为1
wva.setOnItemSelectedListener(new WheelView.OnItemSelectedListener() {
@Override
public void onItemSelected(int selectedIndex, String item) {
Log.d(TAG, "selectedIndex: " + selectedIndex + ", item: " + item);
}
});

final WheelView wv = (WheelView) outerView.findViewById(R.id.wheel_view_wv);

//点击取消
tv_cancel.setOnClickListener(new View.OnClickListener() {

//防止弹出两个窗口
