LogCat錯誤：您必須提供textView的資源ID

我有以下java文件。我剛剛嘗試使用this tutorial創建帶圖像的列表視圖。它在教程中工作，但我的不是。LogCat錯誤：您必須提供textView的資源ID

Main.java

public class Main extends ListActivity { 
String [] proList ={"Java" , "Android", "C#", "C++"} ; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setListAdapter(new MyListAdapter(this,proList)); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
}

和MyListAdapter.java

public class MyListAdapter extends ArrayAdapter <String> { 


private Context context; 
private String [] values ; 

public MyListAdapter(Context context, String[] values) { 
    // TODO Auto-generated constructor stub 
    super(context,R.layout.activity_main, values) ; 
    this.context=context; 
    this.values=values; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 

    LayoutInflater inflator=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View rowView=inflator.inflate(R.layout.activity_main, parent, false); 

    TextView textView=(TextView) rowView.findViewById(R.id.textViewLAbel); 
    ImageView imageView=(ImageView) rowView.findViewById(R.id.imageView1); 

    textView.setText(values[position]); 

    String str = values[position]; 

    if (str.equalsIgnoreCase("Java")){ 
     imageView.setImageResource(R.drawable.java); 

    } 

    else if (str.equalsIgnoreCase("Android")){ 
     imageView.setImageResource(R.drawable.android); 
    } 

    else if (str.equalsIgnoreCase("C#")){ 
     imageView.setImageResource(R.drawable.csharp) ; 
    } 

    else if (str.equalsIgnoreCase("C++")){ 
     imageView.setImageResource(R.drawable.cplus) ; 
    } 

    return super.getView(position, convertView, parent); 
} 
}

我想在XML文件中的錯誤，我的XML文件是：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:padding="5dp" > 

<TextView 
    android:id="@+id/textViewLAbel" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" 
    android:textSize="30sp" /> 

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="50dp" 
    android:layout_height="50dp" 
    android:layout_marginLeft="5dp" 
    android:layout_marginRight="20dp" 
    android:layout_marginTop="5dp" 
    android:src="@drawable/ic_launcher" /> 
</LinearLayout>

我已經看到了兩個類似的問題，但仍然無法找到我的錯誤。

關閉您的LinearLayout。將標籤放在最後。 – 2013-05-09 10:55:39

發佈整個logcat消息 – 2013-05-09 10:58:38

@RajithaSiriwardena如果他從LogCat中收到錯誤，他肯定能夠構建應用程序;如果他的xml是他發佈的，那麼這是不可能的，所以我認爲他只是在發佈他的問題時離開了剪切/粘貼的東西。 – mah 2013-05-09 11:01:31

更換

return super.getView(position, convertView, parent);

與

return rowView;

2013-05-09 10:59:28

是的，現在它可以工作，但圖像在右側 – user2240469 2013-05-09 11:05:52

這是一個不同的問題。 – 2013-05-09 11:10:44

return super.getView（position，convertView，parent）;此代碼確實轉換我認爲因此，在另一個地方的錯誤 – user2240469 2013-05-09 11:16:06

的問題是與線 -

return super.getView(position, convertView, parent);

在您的適配器中。

參數convertView爲空。
中爲每個getView（）的文檔 - convertView

You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)).

因爲要創建一個自己的觀點，你可以simpley回報 -

return /super.getView(position, convertView, parent)/ rowView;

希望這澄清。

謝謝，但通過替換代碼的部分應用程序的佈局也改變（圖像變成右側）。這是一個視頻，這傢伙用super.getView（位置，convertView，父 http://www.youtube.com/watch?v=BKQ8QQ3kxJ0 – user2240469 2013-05-09 11:23:20

你給出的佈局包含圖像的右側。如果你想要改變它，你必須改變佈局 – Anukool 2013-05-09 11:27:51

這是非常有趣的，沒有改變代碼本身，當我把圖像在圖形佈局的左側它不起作用。但是，當圖像在右側 – user2240469 2013-05-09 11:51:48
