【问题描述】:
当用户在列表视图中选择一个元素时如何设置动画?
我正在制作我自己的列表视图适配器,以将偶数行设置为粉红色背景,将奇数行设置为紫色背景。唯一的问题是我不确定如何为用户单击(“触摸”)元素设置动画。
我想过实现 OnTouchListener 并在选择时将背景更改为绿色,但是由于实现了 OnTouchListener,我在行内的按钮可能不再起作用。这是真的吗?
代码:
public class MyAdapter extends BaseAdapter {
public View getView(int position, View convertView, ViewGroup parent) {
// position is the element's id to use
// convertView is either null -> create a new view for this element!
// or not null -> re-use this given view for element!
// parent is the listview all the elements are in
if (convertView == null) {
convertView = mInflater.inflate(R.layout.your_layout, null);
// here you must do whatever is needed to populate the elements of your
// list element layout
...
} else {
// re-use the given convert view
// here you must set all the elements to the required values
}
// your drawable here for this element
convertView.setBackground(...);
// maybe here's more to do with the view
return convertView;
}
}
