将近2个月没写了，今天有了一点空闲时间，所以写一写最近写的一些好玩的东西。先看效果图
效果图.png
一开始需求是直接把200多人的名单，用dialog弹出来，但最后说交互不是太好，选一个人要花费很多时间，要求改为侧滑，但是因为点击每个人员都是可以出现侧滑，而且点击其他位置，要将侧滑隐藏，我实在是不知道如何让侧滑的数据显示到对应的点击位置，所有使用了伪Dialog实现侧滑，BaseExpandableList的adapter是一个比较麻烦的事情，如果你有时间，可以看一看。
现在代码还有一个问题，是当点击最右部分的时候，弹出的Dialog会将布局挡住一部分，所有在弹出Dialog的时候加一个点击位置判断，让他尽可能的不要挡住召唤弹窗的位置。
源代码
显示Dialog的代码
private void showDialogList( ) {
final Dialog dialog = new Dialog(this, R.style.dialog);
View view = getLayoutInflater().inflate(R.layout.dialog_expandable_user, null);
dialog.setContentView(view);
Window window = dialog.getWindow();
window.setGravity(Gravity.RIGHT | Gravity.TOP);
window.setWindowAnimations(R.style.dialogWindowAnim); // 进入，退出动画
WindowManager.LayoutParams lp = window.getAttributes();
lp.width = (TgApplication.getScreenWidth() * 25) / 100; // 屏幕宽度*25/100
lp.height = TgApplication.getScreenHeight() - TgBarUtil.getStatusBarHeight(this); // 屏幕高度-状态栏高度
window.setAttributes(lp);
dialog.show();
ExpandableListView expandableListView = view.findViewById(R.id.expandable);
expandableListView.setGroupIndicator(getDrawable(R.drawable.group_icon_selector));
UserExpandableListViewAdapter adapter = new UserExpandableListViewAdapter(this, serviceUser);
expandableListView.setAdapter(adapter);
/**
* 单击事件 返回 false表示不触发单击事件
*/
expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
return false;
}
});
/**
* Child 单击事件
*/
expandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View view, int groupPosition, int childPosition, long id)
throws RuntimeException {
// 得到被点击的选项
User clickUser = (User) parent.getExpandableListAdapter().getChild(groupPosition, childPosition);
// 其他代码
dialog.dismiss();
return true;
}
});
