Android中的水平ListView？

Horizontal ListView in Android?

提问by Praveen

Is it possible to make the ListViewhorizontally? I have done this using a gallery view, but the selected item comes to the center of the screen automatically. I don't want the selected item at the same spot I clicked. How can I rectify this problem? My idea was to set the ListViewwith a horizontal scroll. Share your idea?

可以ListView横向制作吗？我使用图库视图完成了此操作，但所选项目会自动出现在屏幕中央。我不想在我点击的同一个地方选择项目。我该如何解决这个问题？我的想法是设置ListView水平滚动条。分享你的想法？

As per Android Documentation RecyclerViewis the new way to organize the items in listview and to be displayed horizontally

根据 Android 文档RecyclerView是在列表视图中组织项目并水平显示的新方法

Advantages:

好处：

1. Since by using Recyclerview Adapter, ViewHolder patternis automatically implemented
2. Animation is easy to perform
3. Many more features

Paul doesn't bother to fix bugs of his library or accept users fixes. That's why I am suggesting another library which has similar functionality:

保罗不费心去修复他的库的错误或接受用户的修复。这就是为什么我建议另一个具有类似功能的库：

https://github.com/sephiroth74/Horizo​​ntalVariableListView

Update: on Jul 24, 2013 author (sephiroth74) released completely rewritten version based on code of android 4.2.2 ListView. I must say that it doesn't have all the errors which previous version had and works great!

更新：2013 年 7 月 24 日作者 (sephiroth74) 发布了基于 android 4.2.2 ListView 代码的完全重写版本。我必须说它没有以前版本有的所有错误并且效果很好！

@Paul answer links to a great solution, but the code doesn't allow to use onClickListenerson items children (the callback functions are never called). I've been struggling for a while to find a solution and I've decided to post here what you need to modify in that code (in case somebody need it).

@Paul 回答链接到一个很好的解决方案，但代码不允许在项目子项上使用onClickListeners（回调函数永远不会被调用）。我一直在努力寻找解决方案，我决定在此处发布您需要在该代码中修改的内容（以防有人需要它）。

Instead of overriding dispatchTouchEventoverride onTouchEvent. Use the same code of dispatchTouchEventand delete the method (you can read the difference between the two here http://developer.android.com/guide/topics/ui/ui-events.html#EventHandlers)

而不是覆盖dispatchTouchEventoverride onTouchEvent。使用相同的代码dispatchTouchEvent和删除方法（你可以在这里阅读两者之间的区别http://developer.android.com/guide/topics/ui/ui-events.html#EventHandlers）

@Override
public boolean onTouchEvent(MotionEvent event) {
    boolean handled = mGesture.onTouchEvent(event);
    return handled;
}

Then, add the following code which will decide to steal the event from the item children and give it to our onTouchEvent, or let it be handled by them.

然后，添加以下代码，该代码将决定从项目子项中窃取事件并将其提供给我们的onTouchEvent，或者由他们处理。

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    switch( ev.getActionMasked() ){
        case MotionEvent.ACTION_DOWN:
             mInitialX = ev.getX();
             mInitialY = ev.getY();             
             return false;
        case MotionEvent.ACTION_MOVE:
             float deltaX = Math.abs(ev.getX() - mInitialX);
             float deltaY = Math.abs(ev.getY() - mInitialY);
             return ( deltaX > 5 || deltaY > 5 );
        default:
             return super.onInterceptTouchEvent(ev);
    }
}

Finally, don't forget to declare the variables in your class:

最后，不要忘记在类中声明变量：

private float mInitialX;
private float mInitialY;

Since Google introduced Android Support Library v7 21.0.0, you can use RecyclerView to scroll items horizontally. The RecyclerView widget is a more advanced and flexible version of ListView.

由于 Google 推出了 Android Support Library v7 21.0.0，您可以使用 RecyclerView 水平滚动项目。RecyclerView 小部件是 ListView 的更高级和更灵活的版本。

To use RecyclerView, just add dependency:

要使用 RecyclerView，只需添加依赖项：

com.android.support:recyclerview-v7:23.0.1

Here is a sample:

这是一个示例：

public class MyActivity extends Activity {

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

        RecyclerView recyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);

        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
        recyclerView.setLayoutManager(layoutManager);

        MyAdapter adapter = new MyAdapter(myDataset);
        recyclerView.setAdapter(adapter);
    }
}

Its actually very simple: simply Rotate the list view to lay on its side

它实际上非常简单：只需将列表视图旋转到其一侧即可

mlistView.setRotation(-90);

mlistView.setRotation(-90);

Then upon inflating the children, that should be inside the getView method. you rotate the children to stand up straight:

然后在给孩子充气时，应该在 getView 方法中。你旋转孩子们站直：

 mylistViewchild.setRotation(90);

Edit:if your ListView doesnt fit properly after rotation, place the ListView inside this RotateLayoutlike this:

编辑：如果旋转后您的 ListView 不适合，请将 ListView 放置在此RotateLayout 中，如下所示：

 <com.github.rongi.rotate_layout.layout.RotateLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:angle="90"> <!-- Specify rotate angle here -->

    <ListView
       android:layout_width="match_parent"
       android:layout_height="match_parent">
    </ListView>

My solution is to simply use ViewPagerwidget. It isn't center-locked as Galleryand has a built-in features for recycling views (as ListView). You may see similar approach at Google Play app, whenever you deal with horizontally scrollable lists.

我的解决方案是简单地使用ViewPager小部件。它不是中心锁定的，Gallery并且具有用于回收视图的内置功能（如ListView）。每当您处理可水平滚动的列表时，您可能会在 Google Play 应用程序中看到类似的方法。

You just need to extend PagerAdapterand perform a couple of tweaks there:

您只需要在那里扩展PagerAdapter并执行一些调整：

public class MyPagerAdapter extends PagerAdapter {

    private Context mContext;

    public MyPagerAdapter(Context context) {
        this.mContext = context;
    }

    // As per docs, you may use views as key objects directly 
    // if they aren't too complex
    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        View view = inflater.inflate(R.layout.item, null);
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public int getCount() {
        return 10;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

    // Important: page takes all available width by default,
    // so let's override this method to fit 5 pages within single screen
    @Override
    public float getPageWidth(int position) {
        return 0.2f;
    }
}

As result, you'll have horizontally scrollable widget with adapter, like this:

结果，您将拥有带有适配器的水平可滚动小部件，如下所示：

trick that is working here is the id that I have assigned to ImageView "imgView.setId(v)" and after that applying onClickListener to that I am again fetching the id of the view....I have also commented inside the code so that its easy to understand, I hope this may be very useful... Happy Coding... :)

在这里工作的技巧是我分配给 ImageView“imgView.setId(v)”的 id，然后将 onClickListener 应用到我再次获取视图的 id ......我也在代码中进行了评论它易于理解，我希望这可能非常有用......快乐编码...... :)

You can use RecyclerView in the support library. RecyclerView is a generalized version of ListView that supports:

• Default animations for common item operations

• 用于定位项目的布局管理器
