触发意图联系应用，然后返回到自己的应用

Question

我创建了一个应用程序，它触发一个意图来创建联系人，这让你可以选择任何有必要的意图过滤器的应用程序来创建联系人。然而，我想有任何应用程序创建联系人返回到我的应用程序一旦完成。我已经尝试过这与内置的联系管理器，但它返回到自己，而不是我自己的应用程序。

Answer 1

你想做的是不可能的-对不起。相反，你可以尝试在你的应用程序中捕获联系人数据，而不是启动另一个应用程序。这里有一些代码可以让你开始:

public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    readContacts();
}
public void readContacts(){
     ContentResolver cr = getContentResolver();
     Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
     if (cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                System.out.println("name : " + name + ", ID : " + id);
                // get the phone number
                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
                                       ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                                       new String[]{id}, null);
                while (pCur.moveToNext()) {
                      String phone = pCur.getString(
                             pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                      System.out.println("phone" + phone);
                }
                pCur.close();

                // get email and type

               Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
                        new String[]{id}, null);
                while (emailCur.moveToNext()) {
                    // This would allow you get several email addresses
                        // if the email addresses were stored in an array
                    String email = emailCur.getString(
                                  emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                    String emailType = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
                    int type = emailCur.getInt(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));

                    CharSequence CustomemailType = ContactsContract.CommonDataKinds.Email.getTypeLabel(this.getResources(), type, customLabel);
                  //System.out.println("Email " + email + " Email Type : " + emailType);
                }
                emailCur.close();
