在我的应用中，我想让用户通过手机显示联系人。我使用此example从应用中打开手机通讯录。但现在我想通过复制手机中的所有联系人，在我的应用程序中列出联系人列表。最好的方法是什么？
修改
我已经知道如何显示联系人，但我不知道如何将它们保存到sqlite db。我是初学者，所以任何帮助都表示赞赏。

试试这个例子为我工作。
首先，您需要在mainifest文件中设置权限。你的Mainifest文件看起来应该是这样的。
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.wptrafficanalzer.listviewcontacts"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="15" />
<uses-permission
android:name="android.permission.READ_CONTACTS" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
完成此操作后，您需要在布局文件夹中创建两个XML文件。
activity_main.xml中
<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" >
<ListView
android:id="@+id/lst_contacts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</RelativeLayout>
lv_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
android:id="@+id/tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:textSize="20dp"
android:textStyle="bold" />
<ImageView
android:id="@+id/iv_photo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/tv_name"
android:layout_centerHorizontal="true"
android:padding="5dp" />
<TextView
android:id="@+id/tv_details"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/iv_photo"
/>
</RelativeLayout>
创建布局文件后，您的MainActivity类将如下所示。
MainActivity.Java
public class MainActivity extends Activity {
SimpleCursorAdapter mAdapter;
MatrixCursor mMatrixCursor;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// The contacts from the contacts content provider is stored in this
// cursor
mMatrixCursor = new MatrixCursor(new String[] { "_id", "name", "photo",
"details" });
// Adapter to set data in the listview
mAdapter = new SimpleCursorAdapter(getBaseContext(),
R.layout.lv_layout, null, new String[] { "name", "photo",
"details" }, new int[] { R.id.tv_name, R.id.iv_photo,
R.id.tv_details }, 0);
// Getting reference to listview
ListView lstContacts = (ListView) findViewById(R.id.lst_contacts);
// Setting the adapter to listview
lstContacts.setAdapter(mAdapter);
// Creating an AsyncTask object to retrieve and load listview with
// contacts
ListViewContactsLoader listViewContactsLoader = new ListViewContactsLoader();
// Starting the AsyncTask process to retrieve and load listview with
// contacts
listViewContactsLoader.execute();

private class ListViewContactsLoader extends AsyncTask<Void, Void, Cursor> {

你可以这样做：
添加功能：
private List<Person> getContactList(){
ArrayList<Person> contactList = new ArrayList<Person>();
Uri contactUri = ContactsContract.Contacts.CONTENT_URI;
String[] PROJECTION = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
};
String SELECTION = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";
Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, SELECTION, null, null);
if (contacts.getCount() > 0)
{
while(contacts.moveToNext()) {
Person aContact = new Person();
int idFieldColumnIndex = 0;
int nameFieldColumnIndex = 0;
int numberFieldColumnIndex = 0;
String contactId = contacts.getString(contacts.getColumnIndex(ContactsContract.Contacts._ID));
nameFieldColumnIndex = contacts.getColumnIndex(PhoneLookup.DISPLAY_NAME);
if (nameFieldColumnIndex > -1)
{
aContact.setName(contacts.getString(nameFieldColumnIndex));
}
PROJECTION = new String[] {Phone.NUMBER};
final Cursor phone = managedQuery(Phone.CONTENT_URI, PROJECTION, Data.CONTACT_ID + "=?", new String[]{String.valueOf(contactId)}, null);
if(phone.moveToFirst()) {
while(!phone.isAfterLast())
{
numberFieldColumnIndex = phone.getColumnIndex(Phone.NUMBER);
if (numberFieldColumnIndex > -1)
{
aContact.setPhoneNum(phone.getString(numberFieldColumnIndex));
phone.moveToNext();
TelephonyManager mTelephonyMgr;
mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (!mTelephonyMgr.getLine1Number().contains(aContact.getPhoneNum()))
{
contactList.add(aContact);
}
}
}
}
phone.close();
}
contacts.close();
}
return contactList;
}
Person.java ：
public class Person {
String myName = "";
String myNumber = "";
public String getName() {
return myName;
}
public void setName(String name) {
myName = name;
}
public String getPhoneNum() {
return myNumber;
}
public void setPhoneNum(String number) {
myNumber = number;
}
}
希望这会对你有所帮助。
