我正在使用以下类在国家/地区的列表视图中进行搜索
package com.androidhive.androidlistviewwithsearch;

import android.widget.SimpleCursorAdapter;
public class MainActivity extends Activity {
private ListView lv;
SimpleCursorAdapter cursorAdapter;
ArrayAdapter<String> adapter;
EditText inputSearch;
private SQLiteAdapter mySQLiteAdapter;
ArrayList<HashMap<String, String>> productList;
public static final String COUNTRY_NAME = "COUNTRY_NAME";
String[] countryName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToWrite();
int isEmpty = mySQLiteAdapter.isEmpty();
if (isEmpty == 0) {
mySQLiteAdapter.insert("Afghanistan", "102", "119", "119");
mySQLiteAdapter.insert("Albania", "127", "128", "129");
mySQLiteAdapter.insert("Algeria", "14", "14", "17");
mySQLiteAdapter.insert("American Samoa", "911", "911", "911");
mySQLiteAdapter.insert("Andorra", "118", "118", "110");
mySQLiteAdapter.insert("Angola", "118", "118", "110");
mySQLiteAdapter.insert("Panama", "911", "911", "911");
mySQLiteAdapter.insert("Papua New Guinea /Port Moresby", "", "110", "000");
mySQLiteAdapter.insert("Yemen", "191", "191", "194");
mySQLiteAdapter.insert("Zambia", "991/112", "993/112", "999/112");
mySQLiteAdapter.insert("Zimbabwe", "994/999", "993/999", "995/999");
}
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToRead();
Cursor cursor = mySQLiteAdapter.queueAll();
startManagingCursor(cursor);
List<String> list = new ArrayList<String>();
if (cursor.moveToFirst()) {
while (cursor.isAfterLast() == false) {
String countries = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.COUNTRIES_CONTENT)).toString().trim();
System.out.println("countries: " + countries);
list.add(countries);
cursor.moveToNext();
}
}
countryName = new String[list.size()];
countryName = list.toArray(countryName);
mySQLiteAdapter.close();
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name, countryName);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parentView, View childView, int position, long id) {
Intent intent ;
Bundle b = new Bundle();
b.putString(COUNTRY_NAME, countryName[position]);
intent = new Intent(getApplicationContext(), CountryNumbers.class);
intent.putExtras(b);
startActivity(intent);
finish();
}
});
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
}
}
此代码运行良好并进行搜索，它还执行 setOnItemClickListener 打开包含有关所选国家/地区信息的活动。但是，当我进行搜索并且例如写了“E”时，我发现列表已更改并获取以“E”开头的国家，但是当我按下例如从搜索中获取的第二个国家时，它会打开具有第二个索引的国家“国家名称”数组。如何解决此问题并从搜索中获取所选国家/地区的信息？
希望有人明白我的意思。提前致谢。
