Question

我使用滚轮菜单栏设计了一个页面。轮式菜单栏圈出非常好。但是我希望当图标出现在页面顶部的线条布局上时，应该知道哪个图像正在悬停。它应该是可点击的。我写算法

1）我想在页面顶部放置衬垫布局

2）当图标（这是图像）出现在这个班轮布局上时，它应该是可点击的

3）此布局应该知道悬停在哪个按钮

Answer 1

您可以在布局中的每个按钮或视图上设置onclicklistener。

wheel.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(final View v) {
});

Answer 2

在init函数中使用此代码

wheel.setItemClickEventAtSelectionPosition(false);

wheel.setOnItemClickListener(new WheelAdapter.OnItemClickListener() {

        @Override
        public void onItemClick(WheelAdapter<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub

}
});
