機器人 - 日食 - R的不能被解析爲一個變量ERROR

-1

我得到一個奇怪的錯誤說：月食「R不能解析爲一個變量」機器人 - 日食 - R的不能被解析爲一個變量ERROR

我不知道wath做。

我必須張貼我的Manifest文件嗎？我的xml文件？

我已經tryed：清潔工程更新AVD 更新SDK

這是我的代碼：

//package 

//imports 

public class MainActivity extends Activity implements OnClickListener{ 

public Handler timer = new Handler(); 

public int counter = 0; 

//vars 

TextView mTextView; 
ImageButton finishhimbutton; 
ImageButton resetbutton; 

//images 

public ImageView jb1; 
public ImageView jb2; 
public ImageView jb3; 
public ImageView jb4; 
public ImageView jb5; 
public ImageView jb6; 
    TextView txtCount; 




@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

//define 

     txtCount = (TextView)findViewById(R.id.timer);    
     txtCount.setText(String.valueOf(counter));

你有進口android.R ;.資源文件中的任何錯誤 – Raghunandan

檢查是否有導入android.R而不是您的項目的R類 – stinepike

如果我導入android.r;我在R.layout.activity_main上得到錯誤<---- – CaptainStony
