过滤后未在列表视图上显示正确的结果

Question

我有通过在适配器类中使用过滤器方法完成的搜索视图，所以问题是，每当我输入全名或数字进行搜索时，它不显示结果仅显示 ListView 的第一项但如果我输入第一个字符或编号它的显示结果，所以我希望每当我输入全名或数字时都应该有结果，我进行了调试，我发现我的代码中的所有内容都是正确的，请帮助。

public class AdmitPatientAdapter extends BaseAdapter {

    private Activity activity;
    ArrayList<HashMap<String, String>> data;
    ArrayList<HashMap<String, String>> TempArrList = new ArrayList<>();
    private static LayoutInflater inflater = null;

    public AdmitPatientAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
        activity = a;
        data = d;
        TempArrList.addAll(d);
        inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }


    public int getCount() {
        return TempArrList.size();
    }

使用此代码::

适配器类：

p

ublic class ListViewAdapter extends BaseAdapter { 

// Declare Variables 
Context mContext; 



LayoutInflater inflater; 
private List<WorldPopulation> worldpopulationlist = null; 
private ArrayList<WorldPopulation> arraylist; 

public ListViewAdapter(Context context, List<WorldPopulation> worldpopulationlist) { 
mContext = context; 
this.worldpopulationlist = worldpopulationlist; 
inflater = LayoutInflater.from(mContext); 
this.arraylist = new ArrayList<WorldPopulation>(); 
this.arraylist.addAll(worldpopulationlist); 

} 

public class ViewHolder { 
TextView beamword; 

} 

@Override 
public int getCount() { 
return worldpopulationlist.size(); 
} 

@Override 
public WorldPopulation getItem(int position) { 
return worldpopulationlist.get(position); 
} 

@Override 
public long getItemId(int position) { 
return position; 
} 

public View getView(final int position, View view, ViewGroup parent) { 
final ViewHolder holder; 
if (view == null) { 
holder = new ViewHolder(); 
view = inflater.inflate(R.layout.list_single, null); 
// Locate the TextViews in listview_item.xml 
holder.beamword = (TextView) view.findViewById(R.id.textviewitem); 

view.setTag(holder); 
} else { 
holder = (ViewHolder) view.getTag(); 
} 
// Set the results into TextViews 
holder.beamword.setText(worldpopulationlist.get(position).getBeamword()); 


return view; 
} 

// Filter Class 
public void filter(String charText) { 
charText = charText.toLowerCase(Locale.getDefault()); 
worldpopulationlist.clear(); 
if (charText.length() == 0) { 
worldpopulationlist.addAll(arraylist); 
}  
else  
{ 
for (WorldPopulation wp : arraylist)  
{ 
if (wp.getBeamword().toLowerCase(Locale.getDefault()).contains(charText))  
{ 
worldpopulationlist.add(wp); 
} 
} 
} 
notifyDataSetChanged(); 
} 

} 

在你的课堂上

editsearch.addTextChangedListener(new TextWatcher() { 

@Override 
public void afterTextChanged(Editable arg0) { 
// TODO Auto-generated method stub 
String text = editsearch.getText().toString().toLowerCase(Locale.getDefault()); 
adapter.filter(text); 
} 

@Override 
public void beforeTextChanged(CharSequence arg0, int arg1, 
int arg2, int arg3) { 
// TODO Auto-generated method stub 
} 

@Override 
public void onTextChanged(CharSequence arg0, int arg1, int arg2, 
int arg3) { 
// TODO Auto-generated method stub 
} 
});
