カスタムビューを備えたListViewのSearchView
私はいくつかの助けを必要としています私は自分のプロジェクトにSearchViewを実装しようとしていますが、私のプロジェクトにはカスタムアダプタが接続されたリストビューが含まれています。従業員クラスがあり、名前と年齢のフィールドが含まれているとしましょう。名前のみを使用して従業員をフィルタリングする方法.
public class MainActivity extends Activity implements SearchView.OnQueryTextListener
{
SearchView mSearchView;
ListView mListView;
//String mStrings[]= {"abc","def","efg","ghi","ijk","Apple","agxhsdgc","abbbcc"};
ArrayList<Employee> emp_list=null;
EmployeeAdapter emp_adapter=null;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSearchView=(SearchView) findViewById(R.id.searchView1);
mListView=(ListView) findViewById(R.id.listView1);
emp_list=new ArrayList<Employee>();
emp_list.add(new Employee("ABC", 24));
emp_list.add(new Employee("ACB", 24));
emp_list.add(new Employee("BVF", 28));
emp_list.add(new Employee("BRT", 28));
emp_list.add(new Employee("ANM", 23));
emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list);
mListView.setAdapter(emp_adapter);
// mListView.setAdapter(new ArrayAdapter<String>(this,
// Android.R.layout.simple_list_item_1,
// mStrings));
mListView.setTextFilterEnabled(true);
setupSearchView();
}
private void setupSearchView()
{
mSearchView.setIconifiedByDefault(false);
mSearchView.setOnQueryTextListener(this);
mSearchView.setSubmitButtonEnabled(true);
mSearchView.setQueryHint("Search Here");
}
@Override
public boolean onQueryTextChange(String newText)
{
if (TextUtils.isEmpty(newText.toString())) {
mListView.clearTextFilter();
} else {
mListView.setFilterText(newText.toString());
}
return true;
}
@Override
public boolean onQueryTextSubmit(String query)
{
return false;
}
}
これは、BaseAdapterを拡張するアダプタークラスです。
public class EmployeeAdapter extends BaseAdapter {
Context ctx;
ArrayList<Employee> emp_list;
LayoutInflater linf=null;
EmployeeHolder holder=null;
public EmployeeAdapter(Context ctx, ArrayList<Employee> emp_list) {
super();
this.ctx = ctx;
this.emp_list = emp_list;
linf=(LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public class EmployeeHolder
{
TextView name;
TextView age;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return emp_list.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return emp_list.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if(convertView==null)
{
convertView=linf.inflate(R.layout.row, parent, false);
holder=new EmployeeHolder();
holder.name=(TextView) convertView.findViewById(R.id.name);
holder.age=(TextView) convertView.findViewById(R.id.age);
convertView.setTag(holder);
}
else
{
holder=(EmployeeHolder) convertView.getTag();
}
Employee e=(Employee) getItem(position);
holder.name.setText(e.getName());
holder.age.setText(String.valueOf(e.getAge()));
return convertView;
}
}
前もって感謝します..
この方法を試して、これがあなたを助けることを願っています...

良い答えはありますが、コメントセクションで述べたように、いくつかの問題（onclickのときの間違った位置、serchviewテキストオーバーレイ）がありますので、次の方法でもこれを行うことができます
詳細情報のリファレンス： searchview listview Android
私はそれをテストしましたが、これまでのところ何の問題も発見していません。もしあれば、コメントセクションで言及してください。
