我想根据用户输入搜索自定义列表视图（使用的arrayadaptor）。我已经在自定义列表视图中实现了可过滤的类，但是为了优化高速缓存，我使用了持有者来携带当前行。现在，根据用户输入获取项目变得非常复杂。
任何人都可以帮我解决问题吗？
我的主要课程是，
public class ambulanceActivity extends Activity{
dbhelper db4;
ListView lstview_Items;
int images = R.drawable.call;
final ArrayList<String> mArrayList = new ArrayList<String>();
final ArrayList<String> mArrayList1 = new ArrayList<String>();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ambulance_list);
EditText inputSearch=(EditText) findViewById(R.id.inputSearch);
lstview_Items=(ListView) findViewById(R.id.listView1);
db4 = new dbhelper(getApplicationContext());
db4.creteDB();
Cursor checkerA = db4.getDetails();
checkerA.moveToFirst();
while (!checkerA.isAfterLast()) {
mArrayList.add(checkerA.getString(checkerA
.getColumnIndex("ambname")));
mArrayList1.add(checkerA.getString(checkerA
.getColumnIndex("ambnum")));
checkerA.moveToNext();
}
checkerA.close();
final CustomAdapter adapter=new CustomAdapter(this,mArrayList,images,mArrayList1);
lstview_Items.setAdapter(adapter);
lstview_Items.setTextFilterEnabled(true);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2,
int arg3) {
adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
});
}
}
我的自定义列表视图是，我刚刚在这里实现了可过滤的类
class CustomAdapter extends ArrayAdapter <String> implements Filterable{
Context con;
int images;
ArrayList<String> names;
ArrayList<String> number;
public CustomAdapter(Con c, ArrayList<String> mArrayList,int imgs, ArrayList<String> num) {
super(c, R.layout.list_entry,R.id.contact,mArrayList);
this.con=c;
this.images=imgs;
this.names=mArrayList;
this.number=num;
}
class MyViewHolder extends Activity
{
ImageView myImage;
TextView myContactName;
TextView myContactNumber;
MyViewHolder(View v)
{
myImage=(ImageView) v.findViewById(R.id.police);
myContactName=(TextView) v.findViewById(R.id.name);
myContactNumber=(TextView) v.findViewById(R.id.contact);
}
}
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
MyViewHolder holder=null;
if (row == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.list_entry, parent, false);
holder=new MyViewHolder(row);
row.setTag(holder);
}
else
{
holder=(MyViewHolder) row.getTag();
}
ImageView call=(ImageView) row.findViewById(R.id.police);
call.setTag(position);
call.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent=new Intent("android.intent.action.CALL");
Uri data = Uri.parse("tel:"+number.get(position).toString());
intent.setData(data);
context.startActivity(intent);
}
});
TextView contact=(TextView) row.findViewById(R.id.contact);
holder.myImage.setImageResource(images);
holder.myContactName.setText(names.get(position));
holder.myContactNumber.setText(number.get(position));
return row;
}
}
