我在尝试读取用户的联系人时发生了崩溃，我想是因为模拟器的原因，但我想三重检查，因为我没有基于 Android 的手机。Logcat 给出了一个错误，它无法读取行“id”我错误地命名了那个字符串吗？

最后，我将如何实现一个对话框，看看用户是否希望应用程序读取联系人？

非常感谢:) 代码：

private void checkandImportContacts() {
    // TODO Auto-generated method stub
    SharedPreferences sp = getSharedPreferences(PREFS_CHECK, 0);
     String checkfirstime = sp.getString("key3", null);
     if(checkfirstime !=null && equals("sdhdasudafdsugdiasgdas38ey98d1diass")) {
         finish();
     } else {
         Cursor cursor = getContacts();
           while (cursor.moveToNext()) {
               String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
              Toast.makeText(getApplicationContext(), displayName, Toast.LENGTH_LONG).show();
       }
}
     }




private Cursor getContacts() {
    Uri uri = ContactsContract.Contacts.CONTENT_URI;
    String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME };
    String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ‘" + ("1") + "’";
    String[] selectionArgs = null;
    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC";
    return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
}

private void getDetails(){
        Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
        String[] projection    = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                        ContactsContract.CommonDataKinds.Phone.NUMBER };
        Cursor names = getContentResolver().query(uri, projection, null, null, null);

        int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
        int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
        names.moveToFirst();
        do {

            String name   = names.getString(indexName);
            Log.e("Name new:", name);
            String number = names.getString(indexNumber);
            Log.e("Number new:","::"+number);

        } while (names.moveToNext());
    }

The above retrun all the name and number from from your contact database..
