片段中的按鈕動作

Question

我有片段，並有textview和按鈕，我發現了一個解決方案，爲片段內的按鈕添加動作，但現在我必須在textview中更改文本。我是這樣做的，但它不起作用，你能檢查它嗎？

片段：

public class ArticleFragment extends Fragment { 
    static public int licznik=0; 
    public View view; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 

     view = inflater.inflate(R.layout.article_view, container, false); 
     final TextView article2 = (TextView)view.findViewById(R.id.article); 

     Button menuButton = (Button)view.findViewById(R.id.button1); 
     menuButton.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       article2.setText(++licznik); 
      } 
     }); 

     return view; 
    } 

    @Override 
    public void onStart() { 
     super.onStart(); 

     TextView article = (TextView)view.findViewById(R.id.article); 
     article.setText("Cos tam"); 
    } 

}

XML片段：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <TextView 
     android:id="@+id/article" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"/> 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/reso" 
     android:onClick="action" /> 

</LinearLayout> 

一切都是好，在我不點擊一個按鈕，然後應用程序被sttoped。

Answer 1

我猜這就是問題所在，雖然你們已經張貼任何日誌轉儲：

  article2.setText(++licznik); 

到

  article2.setText(String.valueOf(++licznik)); 

否則它正在尋找一個資源烏爾斯河。
