錯誤：無法指非final的變量名在不同的方法定義的內部類中

Question

你好我的朋友），我有我的課下一個錯誤......

public class AlertDlg { 
public static void AlertShow(final Activity activity, EditText name, EditText track) 
{ 
    LayoutInflater inflater = activity.getLayoutInflater(); 
    View alertLayout = inflater.inflate(R.layout.layout_custom_dialog, null); 
    name = (EditText) alertLayout.findViewById(R.id.et_name); 
    track = (EditText) alertLayout.findViewById(R.id.et_track); 
    AlertDialog.Builder alert = new AlertDialog.Builder(activity); 
    alert.setTitle("Add track number"); 
    //alert.setIcon(R.drawable.plus); 
    alert.setView(alertLayout); 
    alert.setCancelable(false); 
    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      Toast.makeText(activity.getBaseContext(), "Abort", Toast.LENGTH_SHORT).show(); 
     } 
    }); 
    alert.setPositiveButton("Add", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
    ERROR HERE--->String sname = name.getText().toString(); 
      //String track = etPassword.getText().toString(); 
      Toast.makeText(activity.getBaseContext(), "Name: " + sname +" "+ " Track: " , Toast.LENGTH_SHORT).show(); 
     } 
    }); 
    AlertDialog dialog = alert.create(); 
    dialog.show(); 
}} 

錯誤：無法指在不同的方法中定義的內部類內的非最終變量名。我試圖從該數據的EditText。但得到這個錯誤...

調用一個方法：

AlertDlg.AlertShow(MainActivity.this,name,track);

取出內部類，使用它就像你的活動中的功能。

public void AlertShow() 
{ 
    Context mContext = this; 
    LayoutInflater inflater = getLayoutInflater(); 
    View alertLayout = inflater.inflate(R.layout.layout_custom_dialog, null); 
    final EditText name = (EditText) alertLayout.findViewById(R.id.et_name); 
    //final EditText track = (EditText) alertLayout.findViewById(R.id.et_track); 
    AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    alert.setTitle("Add track number"); 
    //alert.setIcon(R.drawable.plus); 
    alert.setView(alertLayout); 
    alert.setCancelable(false); 
    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      Toast.makeText(mContext, "Abort", Toast.LENGTH_SHORT).show(); 
     } 
    }); 
    alert.setPositiveButton("Add", new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      String sname = name.getText().toString(); 
      //String track = etPassword.getText().toString(); 
      Toast.makeText(mContext, "Name: " + sname +" "+ " Track: " , Toast.LENGTH_SHORT).show(); 
     } 
    }); 
    AlertDialog dialog = alert.create(); 
    dialog.show(); 
} 

然後調用它：

AlertShow();
