我的alertdialog不会显示我的listview中的textview。当我点击列表视图时,它只显示列表视图字符串的第一个列表。有人可以帮助我!
package com.example.taxime;
import android.app.AlertDialog;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class FindTaxi extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final String[] number = getResources().getStringArray(R.array.number);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,number));
final String[] taxi = getResources().getStringArray(R.array.taxi);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, taxi));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
AlertDialog.Builder adb=new AlertDialog.Builder(FindTaxi.this);
int selectedPosition = 0;
adb.setTitle(""+taxi[selectedPosition]);
adb.setMessage("Phone Number: "+number[selectedPosition]);
adb.setPositiveButton(TELEPHONY_SERVICE, null);
adb.setNegativeButton("Cancel", null);
adb.show();
}
});
}
}
答案 0 :(得分:0)
(迟到总比没有好,对吗?)
而不是:
int selectedPosition = 0;
adb.setTitle(""+taxi[selectedPosition]);
adb.setMessage("Phone Number: "+number[selectedPosition]);
使用int position
方法收到的onItemClick
参数。因此,上面的三行代码可能会变为: int selectedPosition = position;
adb.setTitle(""+taxi[selectedPosition]);
adb.setMessage("Phone Number: "+number[selectedPosition]);
