前言
最近项目有如下需求：

想了想，正好没有这样的弹窗，就用PopupWindow自己做一个吧
先上效果：

分析
有个title，一个底部按钮，中间是一个列表，这里使用ListView来做，内部的item使用CheckedTextView
可以通过外部设置列表为单选还是多选
mPopup.setTagTxt(getString(R.string.choose_drawback_reason_of_refuse))//设置顶部title的内容
.setButtomTxt(getString(R.string.cancel))//设置底部按钮内容
.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);//单选
/**
* 设置ListView的选择模式
* 多选：AbsListView.CHOICE_MODE_MULTIPLE
* 单选：AbsListView.CHOICE_MODE_SINGLE
*
* @param choiceMode
* @return
*/
public PopupWindowCheckChoose setChoiceMode(int choiceMode) {
if (mListView != null) {
mListView.setChoiceMode(choiceMode);
}
return this;
}
选中了某个/些item后，获取选中的item的position列表
mListView.setOnItemClickListener((parent, view, position, id) -> {
if (mLisenter != null) {
ArrayList<Integer> positionList=new ArrayList<>();
//获取选中的item的position列表
SparseBooleanArray checkedItemPositions = mListView.getCheckedItemPositions();
for (int i=0;i<mList.size();i++){
if (checkedItemPositions.get(i)){
positionList.add(i);
}
}
mLisenter.onItemClick(positionList);
}
});
