在做读取联系人的功能时，界面自动加载时会出现java.lang.IllegalArgumentException: column 'number' does not exist异常，程序出现错误退出。

后经过查询发现在2.0以上版本时ContactsContract.Contacts.CONTENT_URI的Number属性被移动至ContactsContract.CommonDataKinds.Phone.CONTENT_URI此处。

导致目标源数据没有number列。下面给出一个经过一个小时调试修改的正确代码

LinearLayout m_LinearLayout;

ListView m_ListView;

ArrayList<Map<String,String>> listData;

static final String NAME="name";

static final String NUMBER="number";

public void onCreate(Bundle saveInstanceStatus){

super.onCreate(saveInstanceStatus);

/*创建布局对象*/

m_LinearLayout=new LinearLayout(this);

/*设置布局对象的属性*/

m_LinearLayout.setOrientation(LinearLayout.VERTICAL);

m_LinearLayout.setBackgroundColor(Color.BLACK);

/*创建ListView对象*/

m_ListView=new ListView(this);

LinearLayout.LayoutParams param=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

m_ListView.setBackgroundColor(Color.WHITE);

/*添加ListView到LinearLayout布局*/

m_LinearLayout.addView(m_ListView, param);

/*设置显示LinearLayout布局*/

setContentView(m_LinearLayout);

listData=new ArrayList<Map<String,String>>();

//获取数据库Phones的Cursor

Cursor cr=getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

startManagingCursor(cr);

while (cr.moveToNext()) {

Map<String, String> mp=new HashMap<String, String>();

long id=cr.getLong(cr.getColumnIndex("_id"));

Cursor pcur=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"="+Long.toString(id), null, null);

//处理多个号码

String phoneNumbers="";

while(pcur.moveToNext()){

String strPhoneNumber=pcur.getString(pcur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

phoneNumbers+=strPhoneNumber+":";

}

phoneNumbers+="\n";

pcur.close();

String name=cr.getString(cr.getColumnIndex("display_name"));

mp.put(NAME, name);

mp.put(NUMBER, phoneNumbers);

listData.add(mp);

}

ListAdapter adapter=new SimpleAdapter(this,

listData,

android.R.layout.simple_list_item_2,

new String[] {NAME,NUMBER},

new int[] {android.R.id.text1,android.R.id.text2});

//将adapter添加到ListView中

m_ListView.setAdapter(adapter);

//为ListView添加项选择事件

m_ListView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

@Override

public void onItemSelected(AdapterView<?> arg0, View arg1,

int arg2, long arg3) {

// TODO Auto-generated method stub

DisplayToast("滚动到第"+Long.toString(arg0.getSelectedItemId())+"项");

}

@Override

public void onNothingSelected(AdapterView<?> arg0) {

// TODO Auto-generated method stub

}

});

//为ListView添加项点击事件

m_ListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,

long arg3) {

// TODO Auto-generated method stub

DisplayToast("选中了第"+Integer.toString(arg2+1)+"项");

}

});

}

public void DisplayToast(String str){

Toast.makeText(this, str, Toast.LENGTH_SHORT).show();

}
