在android應用程式的開發中，經常要實現的一個功能是呼叫系統自帶的聯絡人介面，做到選擇人之後，取得相應的名稱和號碼，並返回。
android2.0前後實現方式上也有一定的差別：主要是2.0及以上版本聯絡人API發生了變化，由原來的Contacts變成了ContactsContract。
（一） 2.0之前取聯絡人列表的方式：
宣告意圖方式一
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
intent.setData(Contacts.People.CONTENT_URI);
startActivityForResult(intent,
);
PICK_CONTACT
宣告意圖方式二
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("Contacts.People.CONTENT_TYPE");//vnd.android.cursor.dir/person
startActivityForResult(intent,
);
PICK_CONTACT
實現onActivityResult
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case
:
PICK_CONTACT
if (data == null) {
return;
}
Uri uri = data.getData();
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
String number = cursor.getString(cursor.getColumnIndexOrThrow(Phones.NUMBER));
Log.d(TAG, "number" + number);
mContactText.setText(number);
mContactText.setSelection(number.length());
break;
default:
break;
}
}
（二） 2.0之後取聯絡人列表的方式：
宣告意圖方式一
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
宣告意圖方式二
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);//vnd.android.cursor.dir/contact
startActivityForResult(intent, PICK_CONTACT);
實現onActivityResult
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c = managedQuery(contactData, null, null, null, null);
if (c.moveToFirst()) {
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
String phoneNumber = null;
if ( hasPhone.equalsIgnoreCase("1")) {
hasPhone = "true";
} else {
hasPhone = "false" ;
}
if (Boolean.parseBoolean(hasPhone)) {
Cursor phones= getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext()) {
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
}
}
break;
}
}
