[英]how can i get my alertdialog to display listview info?
my alertdialog wont display the textview from my listview. 我的alertdialog将不会从列表视图显示textview。 when i click on the listview it only displays the first list of the list view string. 当我单击列表视图时,它仅显示列表视图字符串的第一个列表。 could someone please help me! 有人可以帮我!
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();
}
});
}
}
(Better late than never, right?) (迟到总比不到好,对吧?)
Instead of this: 代替这个:
int selectedPosition = 0;
adb.setTitle(""+taxi[selectedPosition]);
adb.setMessage("Phone Number: "+number[selectedPosition]);
Make use of the int position
parameter the onItemClick
method receives.
利用onItemClick
方法接收的int position
参数。
So, the three lines of code above might then become:
因此,上面的三行代码可能会变成:
int selectedPosition = position; adb.setTitle(""+taxi[selectedPosition]); adb.setMessage("Phone Number: "+number[selectedPosition]);
