我有两个单独startActivityForResult的 s，它们利用不同的活动。我希望能够在我的主要活动中处理这些活动的结果。

然而，当返回主活动时，该功能被执行（例如，在 requestCodeText 的情况下，btn3 上的文本被设置为正确的值）但随后应用程序冻结。

这是我的代码：

    final int request_CodeNumber = 1;
final int request_CodeText = 2;

    public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    switch(requestCode) {
    case request_CodeText:
        Uri uri = data.getData();
        final Button btn3 = (Button)findViewById(R.id.btnMessage);
        if(resultCode == RESULT_OK) {
            btn3.setText((String) uri.toString());
        }
        break;

    case request_CodeNumber:
        Uri uri2 = data.getData();
        Cursor c = null;
        try {
            c = getContentResolver().query(uri2, new String[]{
                    ContactsContract.CommonDataKinds.Phone.NUMBER,
                    ContactsContract.CommonDataKinds.Phone.TYPE,
                    ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME},
                    null, null, null);
            if (c!= null && c.moveToFirst()) {
                String number = c.getString(0);
                int type = c.getInt(1);
                String contactName = c.getString(2);
                showSelectedNumber(type, number, contactName);
            }
        } finally {
            if (c != null) {
                c.close();
            }
        }
    break;
    }
}

我在 logcat 中得到以下信息：
