【问题描述】：

我有这个 customListView，它显示了手机中的所有联系人，每行都有一个复选框以进行多项选择。问题是我无法显示电话号码。只有联系人姓名出现。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，它导致了问题。 logcat 是

请告诉我我做错了什么

看看[这里][1]。这就是你要找的，我猜。 [1]：***.com/a/12227066/828728

@yugidroid - 这不是我正在做的事情吗？你能进一步解释你的观点吗

【参考方案1】：

   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);

但我已经在代码中使用了游标“cursor = managedQuery(uri, projection, selection, selectionArgs,sortOrder);"

您需要使用 while 循环将每个联系人添加到数组中，如图所示，然后使用适配器将其显示在列表视图中..

我会试一试.. 但我很困惑，如果 listView 显示联系人姓名而没有 while 循环，那么为什么光标需要一个联系人号码循环？

while 循环的作用是逐个获取每个联系人并将其存储为一个数组，然后适配器使用该数组并填充一个列表视图..它对我有用..

我注意到有一个订单项。我正在使用一个包含三个行项目的自定义 listView，所以我需要 FROM 和 TO 字段，这让我再次回到 sqaure 一个
