我的基本适配器中的过滤器未显示正确的结果 [英] filter in my base adapter is not displaying the right results
本文介绍了我的基本适配器中的过滤器未显示正确的结果的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大家好，我在这里的代码中需要一些帮助。
您看到我创建了一个自定义基本适配器并创建了一个过滤方法
请参阅下面的代码：
Hello everyone i need some help in my code here.
You see I create a custom base adapter and create a filter method
see my code below:
private static ArrayList<music> musicList;
private static ArrayList<music> _musicList;
public Filter getFilter() {
return new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
//
final FilterResults searchResults = new FilterResults();
final ArrayList<music> resulta = new ArrayList<music>();
//
if (_musicList == null)
_musicList = musicList;
//
if (constraint != null) {
if (_musicList != null && _musicList.size() > 0) {
for (final music _music : _musicList) {
//
Log.d("constraint", constraint.toString() + " " + _music.getTitle().toString());
if (_music.getTitle().toLowerCase().startsWith(constraint.toString())){
Log.d("add items", _music.getTitle());
resulta.add(_music);
}
}
//
for (music music : resulta) {
Log.d("result item", music.getTitle());
}
searchResults.values = resulta;
}
}
else{
searchResults.values = musicList;
}
return searchResults;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
//
Log.d("final result", results.values.toString());
//
if (results.count == 0)
notifyDataSetInvalidated();
//
musicList = (ArrayList<music>) results.values;
//
notifyDataSetChanged();
}
};
}
以上是我在baseadapter中的过滤方法
这里是我的代码搜索textView。
Above is my filter method in my baseadapter
and here is my code in the search textView.
@Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
musicListAdapter.getFilter().filter(s.toString());
}
另外我查看logCat并知道结果，它确实获取了正确的数据
问题是它显示错误的数据（对不起英文）
我现在需要一些指南请帮助
Also I look at the logCat and to know the result, it did fetch the right data
the problem is it display the wrong data (sorry for the english)
Please I really need some guide right now please help
推荐答案
上面的代码是正确的，问题是我的getView方法我现在只是修改它现在完全正常....这是我的整个代码
The above code is right, the problem is my getView method i just modify it now and it works perfectly fine now.... here is my entire code
public static final int SEARCH_TITLE = 12;
public static final int SEARCH_ARTIST = 23;
public static final int SEARCH_KARAOKENUMBER = 34;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
songListWidgetHolder viewHolder = null;
String title;
String artist;
if (convertView == null) {
//
if (musicList != null && musicList.size() > 0) {
// Log.d("size", String.valueOf(musicList.size()));

.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
//
convertView = mInflater.inflate(R.layout.list_row, null);
final String _title = musicList.get(position).getTitle();
