如何根據spinner中的名稱檢索聯繫人號碼

我是android開發人員中的新成員。我的應用程序想要聯繫人號碼根據名稱，我必須從微調選擇使用android 1.6。提前如何根據spinner中的名稱檢索聯繫人號碼

public void onItemSelected(AdapterView<?> parent, View arg1, 
        int pos, long arg3) 

      { 

       String name,phoneNumber; 
       name=parent.getItemAtPosition(pos).toString(); 

       String[] projection1 = new String[]{ 
         People._ID,People.NAME,People.NUMBER 
        };   
       Cursor cur=getContentResolver().query(People.CONTENT_URI, projection1,People.NAME+"="+name , null, null);    

       phoneNumber=cur.getString(cur.getColumnIndex(People.NUMBER)); 
       Toast.makeText(parent.getContext(), "number="+phoneNumber,Toast.LENGTH_LONG).show(); 
       /* cur.moveToFirst(); 
        if(cur.moveToFirst()) 
        { 
         do 
         { 



         }while(cur.moveToNext()); 

        }*/ 
      }

下面是完整的代碼嘗試在清單

<uses-permission android:name="android.permission.READ_CONTACTS"/>

這

ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null,null, null, null); 
    if (cur.getCount() > 0) { 
     while (cur.moveToNext()) { 
      String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

      if(name.equals(sentTo)){ 
       if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 

        Cursor pCur = cr.query(
        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
        new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER}, 
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
        new String[]{id}, null); 

        while (pCur.moveToNext()) { 
         for(int i=0;i<pCur.getColumnCount();i++) 
          number = pCur.getString(i); 

        } 
        pCur.close(); 
        pCur = null; 
       } 
      } 
     } 
    }

授予權限創建模態類

public class ContactSave { 

    String name; 
    String number; 

    public ContactSave(String name, String number) { 
     this.name = name; 
     this.number = number; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getNumber() { 
     return number; 
    } 

    public void setNumber(String number) { 
     this.number = number; 
    } 

    @Override 
    public String toString() { 
     return 
       "name='" + name + '\'' + 
       ", number='" + number + '\''; 
    } 
}

編寫代碼在MainActivity

import android.content.ContentResolver; 
import android.database.Cursor; 
import android.provider.ContactsContract; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.widget.ArrayAdapter; 
import android.widget.Spinner; 
import android.widget.Toast; 

import java.util.ArrayList; 

public class MainActivity extends AppCompatActivity { 

    Spinner spinner; 
    ArrayList<ContactSave> arrayList = new ArrayList<>(); 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     spinner = (Spinner) findViewById(R.id.spinner); 


     readAllContact(); 

    } 


    private void readAllContact() { 

     ContentResolver cr = getContentResolver(); 
     Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, 
       null, null, null, null); 
     if (cur.getCount() > 0) { 
      while (cur.moveToNext()) { 
       String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
       String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
       if (Integer.parseInt(cur.getString(
         cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
        Cursor cursor = cr.query(
          ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
          null, 
          ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", 
          new String[]{id}, null); 
        while (cursor.moveToNext()) { 
         String phoneNo = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 

         arrayList.add(new ContactSave(name, phoneNo)); 
         Toast.makeText(MainActivity.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show(); 
        } 
        ArrayAdapter<ContactSave> dataAdapter = new ArrayAdapter<ContactSave>(this, android.R.layout.simple_spinner_item, arrayList); 
        spinner.setAdapter(dataAdapter); 
        cursor.close(); 
       } 
      } 
     } 
    } 
}

XML文件中的代碼

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin"> 


    <Spinner 
     android:id="@+id/spinner" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"/> 
</RelativeLayout>
