我收到以下异常：

在以下代码中：

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.e(TAG, getMethodName());

        if(resultCode == Activity.RESULT_OK){
            Cursor cursor = getContentResolver().query(data.getData(), new String[]       {Contacts.DISPLAY_NAME}, null, null, null);
            if(cursor.moveToFirst()){
                int columnindex = cursor.getColumnIndex(Contacts.DISPLAY_NAME);
                String name = getString(columnindex);
                nameTextView.setText(name);
            }
        }
        super.onActivityResult(requestCode, resultCode, data);
    }

和

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    nameTextView = (TextView)this.findViewById(R.id.name);
    Uri uri = Uri.parse("content://contacts/people");
    Intent intent = new Intent(Intent.ACTION_PICK, uri);
    startActivityForResult(intent, PICK_CONTACT_SUBACTIVITY);
}

请说明问题的原因和原因，以及如何解决这个问题。

感谢您的帮助

Answer 1

在String name = getString(columnindex)中，您正在调用Context.getString，这在这里完全没用（它加载字符串资源并期望资源ID）。请改用cursor.getString来获取游标列的内容。
