将联系人信息读取到列表中显示

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();
}
