java - startActivityForResult() 之后检索联系人姓名和电话

Question

这个问题已经有答案了:

Android contacts Display Name and Phone Number(s) in single database query? (3 个回答)

已关闭 9 年前。

我已经开始一项新的意向 Activity 以获得结果代码:

    Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, Phone.CONTENT_URI);  

    startActivityForResult(contactPickerIntent, 1);

现在我想获取电话和号码:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 1) {

        if(resultCode == RESULT_OK){

            Uri contactUri = data.getData();

            String[] pN = {Phone.NUMBER};

            String[] pNa = {Phone.CONTACT_ID};//idk

            Cursor cP = getContentResolver().query(contactUri, pN, null, null, null);
            cP.moveToFirst();

            Cursor cPa = getContentResolver().query(contactUri, pNa, null, null, null);
            cPa.moveToFirst();

            int numc = cP.getColumnIndex(Phone.NUMBER);
            String num = cP.getString(numc);

            int namec = cPa.getColumnIndex(Phone.CONTACT_ID);//idk
            String name = cPa.getString(namec);//idk

            Log.i("", name);

        }
        if (resultCode == RESULT_CANCELED) {
            //DO OTHER STUFF
        }
    }
}   

电话号码没问题，但我无法检索到联系人的名字!

 Uri uri = data.getData();

        Cursor cursor = getContentResolver().query(uri, null, null, null, null);

        cursor.moveToFirst();
        name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

        cursor.moveToFirst();
        number = cursor.getString(cursor.getColumnIndex(Phone.NUMBER));
