android 源码编译 找不到符号,Android编译错误：无法找到符号类Textview

我在我的android测试应用程序开发期间运行代码时出现错误。在FindBeerActivityAndroid编译错误：无法找到符号类Textview

Error:(20, 9) error: cannot find symbol class Textview

Error:(20, 38) error: cannot find symbol method findViewByID(int)

Error:(22, 35) error: cannot find symbol method FindviewbyId(int)

Error:(24, 9) error: cannot find symbol class string

Error:(26, 9) error: cannot find symbol variable brnads

源代码如下所示。

package com.hfad.beeradviser;

import android.os.Bundle;

import android.app.Activity;

import android.view.View;

import android.widget.Spinner;

import android.widget.TextView;

public class FindBeerActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_find_beer);

}

//Call when the button gets clicked

public void onClickFindBeer(View view) {

//get a reference to the Textview

Textview brands = (TextView) findViewByID(R.id.brands) ;

//get a reference to the Spinner

Spinner color = (Spinner) FindviewbyId(R.id.color);

//Get the selected item in the Spinner

string beerType = String.valueOf(color.getSelectedItem());

//Display the selected item

brnads.setText(beerType);

}

}

你能帮我解决这个错误吗？
