java - onTextChanged，无法正常工作

Question

嘿伙计们，我需要我的搜索功能来充当联系人。我正在从服务器检索我的参与者列表，并在用户搜索以获取结果时重建它。胡佛我只有在他们输入全名时才能让它工作。让我给你看我的代码。我尝试了很多组合。任何想法？这是儿童饥饿联盟的捐赠应用程序。=]

这只是在一个 for 循环中添加每个名称 fyi

if (searchQ.contains(child.first_name.toLowerCase()) 
|| searchQ.matches(child.last_name.toLowerCase()) {

 id = child.id;
 addChildToList(child); 

 }

 if (searchQ.matches("")){
    addChildToList(child);


 }

这是我的文本观察器

public void searchChild(){
    final EditText ET = (EditText) findViewById(R.id.search);


    // create the TextWatcher
    TextWatcher textWatcher = new TextWatcher() {

        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {



            // Rebuilds the list
            String searchQ = ET.getText().toString();
             getChildrenListSearch(searchQ);


        }

        @Override
        public void afterTextChanged(Editable editable) {
            // Remove rows that do no match
            TableLayout tl = (TableLayout)findViewById(R.id.childList); 
            tl.removeAllViews();


        }
    };

    //we must add the textWatcher to our EditText
    ET.addTextChangedListener(textWatcher);

    }

反过来...

if (searchQ.contains(child.first_name.toLowerCase()) 
    || searchQ.matches(child.last_name.toLowerCase()) {

     id = child.id;
     addChildToList(child); 

     }

对这个...

if (child.first_name.toLowerCase().contains(searchQ) 
        || searchQ.matches(child.last_name.toLowerCase()) {

         id = child.id;
         addChildToList(child); 

         }
