android打开系统联系人界面

时间:2022-12-09 16:57:48


在android应用程序的开发中,经常要实现的一个功能是调用系统自带的联系人界面,做到选择人之后,取得相应的名称和号码,并返回。

android2.0前后实现方式上也有一定的差别:主要是2.0及以上版本联系人API发生了变化,由原来的Contacts变成了ContactsContract。

(一) 2.0之前取联系人列表的方式:

声明意图方式一

Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
intent.setData(Contacts.People.CONTENT_URI);
startActivityForResult(intent,

PICK_CONTACT

);

声明意图方式二

Intent intent  = new Intent(Intent.ACTION_PICK);
intent.setType("Contacts.People.CONTENT_TYPE");//vnd.android.cursor.dir/person
startActivityForResult(intent,

PICK_CONTACT

);
实现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之后取联系人列表的方式:

声明意图方式一

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);

声明意图方式二

Intent intent = new Intent(Intent.ACTION_PICK);  
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);//vnd.android.cursor.dir/contact
startActivityForResult(intent, PICK_CONTACT);
实现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;
}
}
