我有这个customListView，显示手机上的所有联系人，每行有一个复选框，供多个选择。问题是我无法显示电话号码。只出现联系人姓名。代码是
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
public class AddContacts extends Activity implements OnClickListener {
static final String[] FROM = { ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME };
static final int[] TO = { R.id.contact_name, R.id.phone_number };
ListView list;
Cursor cursor;
SimpleCursorAdapter adapter;
Button AddNumber;
static final String TAG = "In AddContacts";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
AddNumber = (Button) findViewById(R.id.AddNumbers);
number1 = (EditText) findViewById(R.id.NumberField1);
number2 = (EditText) findViewById(R.id.NumberField2);
number3 = (EditText) findViewById(R.id.NumberField3);
AddNumber.setOnClickListener(this);
list = (ListView)findViewById(R.id.lists);
Log.d(TAG, "onCreate");
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME };
String selection = ContactsContract.CommonDataKinds.Phone.IN_VISIBLE_GROUP
+ " = '1'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
cursor = managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
adapter = new SimpleCursorAdapter(this, R.layout.row, cursor, FROM, TO);
list.setAdapter(adapter);
}
@Override
public void onClick(View v) {
Log.d(TAG, "onClicked method");
}
}
现在程序在运行时因IllegalArgument异常而崩溃。当我使用final String[] FROM = { ContactsContract.CommonDataKinds.Phone.NUMBER时，它引起了问题。
logcat是

请告诉我我做错了什么
感谢。

USE CURSOR FOR THIS..FOR E.G Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,null,null, null); pno=new String[phones.getCount()]; Log.d("rows",Integer.toString(phones.getCount())); Log.d("phone","here"); while (phones.moveToNext()) { String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); String name=phones.getString(phones.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); Log.i("Number + Name", phoneNumber + name); } if(phones.getCount()>0) { int i=0; if(phones.moveToFirst()) { do { String phoneNumber1 = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); String name1=phones.getString(phones.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); pno[i]=name1 + " , " + phoneNumber1; i++; }while(phones.moveToNext()); } phones.close(); } ArrayAdapter<String> adapter=new ArrayAdapter<String> (ContactFetch.this,android.R.layout.simple_list_item_1,pno); mContactList.setAdapter(adapter); }
