機器人通入參數onclick事件

Question

在下面的代碼如何傳遞到命令pwd onclick事件

String pwd ="/root"; 

final ListView lv = (ListView) findViewById(R.id.list); 
lv.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) 
     Toast.makeText(MainActivity.this,pwd , Toast.LENGTH_SHORT).show(); 
    } 

EDIT 1：

final String pwd = null; 

string pwd ="root"; //Error remove final keyword 
final ListView lv = (ListView) findViewById(R.id.list); 
lv.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) 
     Toast.makeText(MainActivity.this,pwd , Toast.LENGTH_SHORT).show(); 
    }

聲明onCreate方法上方的字符串PWD。

class demo extends Activity 
{String pwd; 
onCreate() 
{pwd="/root"; 
final ListView lv = (ListView) findViewById(R.id.list); 

lv.setOnItemClickListener(new OnItemClickListener() { 
public void onClick(View arg0) { 
Toast.makeText(MainActivity.this,pwd , Toast.LENGTH_SHORT).show(); 

    } 
     }

這是多麼我已經做到了一次

public class NatigationOnClick implements OnClickListener { 

    String title; 
    String html; 
    private QuickActionWeb webQuickAction; 
    private Context context; 
    private View row; 

    public NatigationOnClick(String title, String html, Context context, 
      View row) { 
     this.title = title; 
     this.html = html; 
     this.context = context; 
     this.row = row; 
    } 

    public void onClick(View v) { 

     webQuickAction = new QuickActionWeb(context, QuickActionWeb.VERTICAL, 
       title + "<br/>" + html); 
     webQuickAction.show(row); 

    } 

} 

現在

...

view.setOnClickListener(new NatigationOnClick(title, html, context, row)); 

希望能夠幫助

也許這可以幫助你：

final ListView lv = (ListView) findViewById(R.id.list); 
lv.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      Toast.makeText(MainActivity.this, getPwd(), Toast.LENGTH_SHORT).show(); 
     } 
}); 


String pwd = "root"; 

private String getPwd() 
{ 
    return pwd; 
}
