android 获取联系人的姓名和电话,无法获取电话

============问题描述============


代码如下
package com.example.sysaction;

import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.CursorLoader;
import android.content.Intent;
import android.database.Cursor;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class SysAction extends Activity {

	final int PICK_CONTACT = 0;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		Button bn = (Button)findViewById(R.id.bn);
		bn.setOnClickListener(new OnClickListener(){
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				Intent intent = new Intent();
				intent.setAction(Intent.ACTION_GET_CONTENT);
				intent.setType("vnd.android.cursor.item/phone");
				startActivityForResult(intent,PICK_CONTACT);
			}
		});
	}

	@TargetApi(Build.VERSION_CODES.HONEYCOMB)
	@SuppressLint("NewApi")
	public void onActivityResult(int requestCode, int resultCode, Intent data)
	{
		super.onActivityResult(requestCode, resultCode, data);
		switch(requestCode)
		{
		case(PICK_CONTACT):
			if(resultCode == Activity.RESULT_OK)
			{
				Uri contactData = data.getData();
				CursorLoader cursorLoader = new CursorLoader(this, contactData, null, null, null, null);
				Cursor cursor =cursorLoader.loadInBackground();
				
				if(cursor.moveToFirst())
				{
					String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
					String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
					String phoneNumber = "此联系人暂未输入电话号码";
					Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+contactId, null, null);
					
					if(phones.moveToFirst())
					{
						phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
					}
					
					phones.close();
					EditText show = (EditText)findViewById(R.id.show);
					show.setText(name);
					EditText phone = (EditText)findViewById(R.id.phone);
					phone.setText(phoneNumber);
				}
				cursor.close();
			}
		break;
		
		}
	}

}


ContactsContract.CommonDataKinds.Phone.CONTACT_ID 返回的值为null

============解决方案1============


引用 3 楼 bdmh 的回复:
不是所有的都能拿到,由于移动运营商没有把手机号码的数据写入到sim卡中


你这是从外星来的吗

============解决方案2============



intent.setType("vnd.android.cursor.item/phone");

改成
intent.setType("vnd.android.cursor.item/phone_v2");

然后去掉重复创建的cursor。
代码如下:
public class SysAction extends Activity {
	 
    final int PICK_CONTACT = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sys_action);
         
        Button bn = (Button)findViewById(R.id.bn);
        bn.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent();
                intent.setAction(Intent.ACTION_GET_CONTENT);
                intent.setType("vnd.android.cursor.item/phone_v2");
                startActivityForResult(intent,PICK_CONTACT);
            }
        });
    }
 
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    @SuppressLint("NewApi")
    public void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);
        switch(requestCode)
        {
        case(PICK_CONTACT):
            if(resultCode == Activity.RESULT_OK)
            {
                Uri contactData = data.getData();
                CursorLoader cursorLoader = new CursorLoader(this, contactData, null, null, null, null);
                Cursor cursor =cursorLoader.loadInBackground();
                if (cursor.moveToFirst())
                {
                    String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    EditText show = (EditText)findViewById(R.id.show);
                    show.setText(name);
                    EditText phone = (EditText)findViewById(R.id.phone);
                    phone.setText(phoneNumber);
                }
                cursor.close();
            }
        break;
         
        }
    }
}

============解决方案3============


这样:
/**读取通讯录异步Handler*/
private AsyncQueryHandler asyncQuery;
/**
 * 读取通讯录
 */
private void readContacts(){
asyncQuery = new ContactAsyncQueryHandler(getContentResolver());
Uri uri = Uri.parse("content://com.android.contacts/data/phones");    
        String[] projection = { "_id", "display_name", "data1", "sort_key" };    
        asyncQuery.startQuery(0, null, uri, projection, null, null,    
                "sort_key COLLATE LOCALIZED asc");
}

//异步查询联系人  
    private class ContactAsyncQueryHandler extends AsyncQueryHandler {    
    
        public ContactAsyncQueryHandler(ContentResolver cr) {    
            super(cr);    
        }    
    
        protected void onQueryComplete(int token, Object cookie, Cursor cursor) {    
            if (cursor != null && cursor.getCount() > 0) {    
             ArrayList<CallsItem> list = new ArrayList<CallsItem>();
                cursor.moveToFirst();    
                for (int i = 0; i < cursor.getCount(); i++) {  
                 CallsItem item = new CallsItem();    
                    cursor.moveToPosition(i);    
                    String name = cursor.getString(1);    
                    String number = cursor.getString(2);    
                    String sortKey = cursor.getString(3);  
                    if (number.startsWith("+86")) {    
                        number = number.substring(3); //去掉+86   
                    }
                    item.name = name;
                    item.number = number;
                    item.sort = sortKey;
                    list.add(item);
//                    System.out.println("name:" + name + " number:" + number + " sort:" + sortKey);
                }
                app.allList = list;
            }    
        }    
    }
