Andorid ListView：onClickListener和過濾器問題

Question

我在我的片段中實現了自定義列表視圖（使用其自定義適配器）。有兩個問題：

1）當我單擊列表中的項目時，即使setOnItemClickListener已實施，也不會發生任何事情。

2）我想過濾我的列表，所以我在列表頂部添加了一個可編輯的TextView實現addTextChangedListener。它工作的很好，但是當我在列表中的TextView唯一的第一個元素中刪除所有字符的出現了，不是所有如我所料

這裏有一種myfragment

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:clickable="true" 
    android:focusable="true" 
    android:background="#ffffff"> 

    <EditText 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:inputType="textPersonName" 
     android:ems="10" 
     android:id="@+id/editableText" 
     android:layout_gravity="center_horizontal" 
     android:editable="true" 
     android:hint="Search Here" 
     android:padding="20dp" 
     android:layout_marginTop="10dp" 
     android:layout_marginBottom="10dp" /> 

    <ListView 

     android:id="@+id/listSearch" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:footerDividersEnabled="false" 
     android:headerDividersEnabled="false" 
     android:paddingStart="15dp" 
     android:paddingEnd="15dp" /> 

</LinearLayout> 

這裏有是XML我的片段的一部分代碼。

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedBundle) { 

    View firstAccessView; 
    if(savedBundle==null) { 
     firstAccessView = inflater.inflate(R.layout.search_fragment_layout, null); 

     ((ActionBarActivity)getActivity()).getSupportActionBar().setTitle("Search Friend"); 

     for(int i=0; i<8; i++){ 
      Contact c = new Contact(idContact[i], nameSurname[i], facebookId[i], timeStamp[i]); 
      this.rows.add(c); 

     } 


     adapter = new SearchListAdapter(getActivity(), this.rows); 
     list = (ListView) firstAccessView.findViewById(R.id.listSearch); 
     list.setAdapter(adapter); 

     list.setOnScrollListener(this); 
     list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
            int position, long id) { 
       //TODO Auto-generated method stub 

       Toast.makeText(getActivity().getApplicationContext(), "item selected", Toast.LENGTH_SHORT).show(); 

      } 
     }); 

     this.editableText = (TextView) firstAccessView.findViewById(R.id.editableText); 
     this.editableText.addTextChangedListener(new TextWatcher() { 
      @Override 
      public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

      } 

      @Override 
      public void onTextChanged(CharSequence s, int start, int before, int count) { 
       List<Contact> temp = new ArrayList<Contact>(); 
       int length = editableText.getText().length(); 
       temp.clear(); 
       for(int i = 0; i<rows.size(); i++){ 
        if(editableText.getText().toString().equalsIgnoreCase("")){ 
         list.setAdapter(new SearchListAdapter(getActivity(), rows)); 
        } 
        if(length < rows.get(i).getName().length()){ 
         if(editableText.getText().toString().equalsIgnoreCase((String)rows.get(i).getName().subSequence(0,length))){ 
          temp.add(rows.get(i)); 

         } 
        } 

       } 
       if(temp.size()>0){ 
        list.setAdapter(new SearchListAdapter(getActivity(), temp)); 
       } 

      } 

      @Override 
      public void afterTextChanged(Editable s) { 

      } 
     }); 

    }else{ 
     firstAccessView = getView(); 
    } 
    return firstAccessView; 
} 

Answer 1

進口 進口android.widget.AdapterView.OnItemClickListener;

，並使用此代碼

list.setOnItemClickListener(new OnItemClickListener() { 
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
    //code here 
}); 

}
