Android自定義列表視圖 - 無法顯示

Question

我的第一個問題在這裏，所以很抱歉，如果出現問題。

我有我的顯示列表視圖定製，我試圖做同樣喜歡這裏的問題：http://www.learn2crack.com/2013/10/android-custom-listview-images-text-example.html

首先，在MainActivity我使用ViewFlipper，但我認爲這並不重要。

vieFli = (ViewFlipper) findViewById(R.id.viewFlipper); 
    vieFli.setHorizontalScrollBarEnabled(true); 

    View vie2 = View.inflate(this, R.layout.activity_friends, null); 
    vieFli.addView(vie2); 

這裏是activity_friends.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".FriendsActivity"> 

<Button 
    android:id="@+id/add_friend_button" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="Add friend" /> 

<ListView 
    android:id="@+id/list" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/add_friend_button"></ListView> 
</RelativeLayout> 

這裏是FriendList.java（只是適配器）：

public class FriendList extends ArrayAdapter<String> { 
private final Activity context; 
private final String[] friendName; 
private final Integer[] imageId; 

public FriendList(Activity context, String[] friendName, Integer[] imageId) { 
    super(context, R.layout.one_row, friendName); 
    this.context = context; 
    this.friendName = friendName; 
    this.imageId = imageId; 
} 

@Override 
public View getView(int position, View view, ViewGroup parent) { 
    LayoutInflater inflater = context.getLayoutInflater(); 
    View rowView = inflater.inflate(R.layout.one_row, null, true); 
    TextView txtTitle = (TextView) rowView.findViewById(R.id.txt); 
    ImageView imageView = (ImageView) rowView.findViewById(R.id.img); 
    txtTitle.setText(friendName[position]); 
    imageView.setImageResource(imageId[position]); 
    //txtTitle.setVisibility(View.VISIBLE); 
    //imageView.setVisibility(View.VISIBLE); 
    return rowView; 
} 

@Override 
public int getCount() { 
    return friendName.length; 
} 

@Override 
public String getItem(int arg0) { 
    return friendName[arg0]; 
} 

@Override 
public long getItemId(int arg0) { 
    return arg0; 
} 
} 

接下來我想告訴你的是one_row.xml（如何我想代表我的ListView中的一行）：

<?xml version="1.0" encoding="utf-8"?> 
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 
<TableRow> 
    <ImageView 
     android:id="@+id/img" 
     android:layout_width="50dp" 
     android:layout_height="50dp"/> 
    <TextView 
     android:id="@+id/txt" 
     android:layout_width="wrap_content" 
     android:layout_height="50dp" /> 
</TableRow> 
</TableLayout> 

與好友活動這是在ViewFlipper加載：

public class FriendsActivity extends ActionBarActivity { 

ListView list; 
String[] friendName = { 
     "Michael", 
     "James" 
}; 
Integer[] imageId = { 
     R.drawable.image1, 
     R.drawable.image2 
}; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_friends); 

    FriendList adapter = new FriendList(this, friendName, imageId); 
    list = (ListView) findViewById(R.id.list); 
    list.setAdapter(adapter); 
    adapter.notifyDataSetChanged(); 
    list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, 
           int position, long id) { 
      // Toast.makeText(FriendsActivity.this, "You Clicked at " +web[+ position], Toast.LENGTH_SHORT).show(); 
     } 
    }); 
} 
... 

這根本教程的複製鏈接我在郵局的開始，並沒有爲我工作。你能告訴我問題在哪裏嗎？當我讀到其他一些問題時，我發現xml的佈局存在問題，但無法在我的系統中找到它。

感謝您的幫助。

試圖改變行getView(...)

View rowView = inflater.inflate(R.layout.one_row, null, true); 

是：

View rowView = inflater.inflate(R.layout.one_row, parent, false);
