输入框的下拉联想list
# 输入框的下拉联想列表pop实现
基于ListPopupWindow. 实现popupWindow不被挤开,悬浮于软键盘之上的效果
editText.addTextChangedListener(new TextWatcher(){
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
super.onTextChanged(s, start, before, count);
String str = s.toString();
if(pop != null){
pop.dismiss();
pop = null;
}
if(str.endsWith("@")){
showPopEmail(str);
}
}
});
