Android listview edittext过滤空间按钮? [英] Android listview edittext filter space button?

问题描述

我创建了一个过滤器列表视图，用户将通过edittext输入输入，结果在列表视图中进行过滤.

I have created a filter listview where user will enter input via edittext and results are filtered in the listview.

代码运行良好，但是当我按下空格按钮时，列表视图的结果会消失.如何在不关闭列表视图内容的情况下在搜索输入中添加空格??

The code is running good but when ever i press Space button, results in the list view disappears. how can i add space in search input without dismissing the listview contents ??

这是我当前的代码:

myListview.setTextFilterEnabled(true);

    edNearBy.addTextChangedListener(new TextWatcher() {

        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub

        }

        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub  

            NearByActivity.this.aa.getFilter().filter(s);

        }
    });

推荐答案

这样做:

public void afterTextChanged(Editable s) {
    String st = s.toString().trim();            
    NearByActivity.this.aa.getFilter().filter(st);
}

但不要这样过滤，这是正确的.
