我該如何解決OnClickListener1

這是我的代碼。這裏有一些錯誤，我無法解決它。任何人都可以幫助我嗎？ view.OnClickListener和View v中存在錯誤。如果我使用快速修復來修復錯誤，則會出現另一個錯誤。請幫助我：'（我該如何解決OnClickListener1

什麼錯誤？發佈您的logcat – 2012-02-20 07:25:24

錯誤在view.OnClickListener查看v Button.setOnClickListener – 2012-02-20 07:29:51

如果錯誤是在線編譯時間，那麼最有可能的位置：

public void onClick(View v) //To do auto generated method 
    { 
    Editable host=edt.getText(); 
    } 
    InetAddress addr=null;

你已經關閉的方法定義爲唯一的語句，如果你想將所有下面的代碼成的onClick方法，遵循：

public void onClick(View v) //To do auto generated method 
    { 
    Editable host=edt.getText(); 

    InetAddress addr=null; 

      Object host; 
      try 
      { 
       addr=InetAddress.getByName(host.toString()); 
      } 
    catch(UnknownHostException e) //To do auto generated catch block 
    { 
     e.printStackTrace(); 
    } 
    try 
    { 
     if(addr.isReachable (5000)) 
     { 
      text.append("\n" +host+ "-Respond Ok"); 
     } 
     else 
     { 
      text.append("\n"+host); 
     } 
    } 
    catch(IOException e){ 
     text.append("\n"+e.toString()); 
    } 


    try 
    { 
    String pingCmd="ping -c5"+host; 
    String pingResult=""; 
    Runtime r = Runtime.getRuntime(); 
    Process p = r.exec(pingCmd); 
    BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream())); 
    String inputLine; 
    while((inputLine = in.readLine())!=null) 
    { 
     System.out.println(inputLine); 
     text.setText(inputLine+"\n\n"); 
     pingResult += inputLine; 
     text.setText(pingResult); 
    } 
    in.close(); 
    } 
    catch(IOException e) 
    { 
     System.out.println(e); 
    } 
     TextView tv = new TextView(this); 
     tv.setText("\t\t\t\t** Network Tracer ** \n\n\t\tWelcome to Android Network Tracer!"); 
     setContentView(tv); 
}

如何更換驗證碼：

protected void onCreate(Bundle savedInstanceState) //To do auto generated method 
     { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      edt=(EditText)findViewById(R.id.edt); 
      text=(TextView)findViewById(R.id.text); 
      ping=(Button)findViewById(R.id.ping); 
      Button.setOnClickListener(this); 
     }

與此：

protected void onCreate(Bundle savedInstanceState) //To do auto generated method 
     { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      edt=(EditText)findViewById(R.id.edt); 
      text=(TextView)findViewById(R.id.text); 
      ping=(Button)findViewById(R.id.ping); 
      ping.setOnClickListener(this); 
     }

讓我們知道這是否正常工作。如果不是，那麼請不要投下這個答案:)
