Stringbuffer无法访问的语句

Question

你好每个人都有问题。我想在Android设备上显示一些数据，但我面临的错误是StringBuffer（无法访问的Statement）这里是我的代码

public void ShowData()
    {
        btnShow.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Cursor result = database.showAllData();
                        if (result.getCount() == 0);
                        {
                            showMessage("Error","Nothing is here");
                            return;
                        }
                        StringBuffer buffer = new StringBuffer();
                        while(result.moveToNext())
                        {
                            buffer.append("name"+result.getString(0)+"\n");
                            buffer.append("userName"+result.getString(0)+"\n");
                            buffer.append("password"+result.getString(0)+"\n\n");
                        }
                        showMessage("Data",buffer.toString());
                    }
                }
        );
    }
    public void showMessage (String title, String message)
    {
        AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
        builder.setCancelable(true);
        builder.setTitle(title);
        builder.setMessage(message);
        builder.show();
    }

在;之后移除if (result.getCount() == 0);。它终止if语句，后面的语句不是有条件的，而是每次都会执行。
