Question

能否横向使<代码>ListView? 我已经用快乐观点这样做,但选定项目自动进入屏幕中心。我不想在我点击的同一地点选定项目。我如何纠正这一问题? 我的想法是将<代码>ListView与横向滚动挂钩。分享你们的想法?

Answer 1

As per Anders RevolrView 这是组织清单中项目和横向展示的新方式。

<><>Advantages:

Since by using Recyclerview Adapter, ViewHolder pattern is automatically implemented
Animation is easy to perform
Many more features

<>萨摩亚>

rel=“noreferer”>surviving withandroid.com

仅添加以下部分,使<代码>ListView横向从纵向向上。

<Code-snippet>

LinearLayoutManager layoutManager= new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL, false); mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view); mRecyclerView.setLayoutManager(layoutManager);

Answer 2

Paul don t bother to fix bugs of his Library or receiveuser fixes. 因此,我建议另一个具有类似功能的图书馆:

https://github.com/sephiroth74/HorizontalVariableListView

<>Update:在Jul 24,2013年,作者(sephiroth74)根据代码和4.2.2 清单意见发表了完全改写的版本。我必须说,它并没有出现以前版本所存在和行之有效的所有错误!

Answer 3

@Paul回答与一个伟大解决办法的联系,但该法典允许在项目儿童方面使用<>strong>onClickListeners(背书功能从未被叫)。我在寻求解决办法的同时,一直在挣扎,我决定在这里提出你们需要修改的守则(如果有人需要的话)。

页: 1 活动。采用相同的<代码>发送地址并删除该方法(可读到以下两点之间的差额:)

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

之后,添加以下法典,决定从项目儿童那里偷窃活动,并将其列入,或由他们处理。

@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);
    }
}

最后,不要忘记宣布贵类变量:

private float mInitialX;
private float mInitialY;

Answer 4

由于谷歌引进了“支持图书馆”第21.0.0号,你可以横向使用“循环器”号进行滚动。回收观点更先进,更灵活。

使用回收观点,只是增加依赖:

com.android.support:recyclerview-v7:23.0.1

样本如下:

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);
    }
}

更多信息回收观点:

Answer 5

这是少许的(非常的)晚,但如果有人在后来来到这里,我就这样说了。

The Support Library as of the Lee preview has a ReillirView 这正是你们想要的。

现在,你只能通过L preview SDK取得这一信息,你需要制定minSdk至L。但是,在正式撤出L之前,你可以把所有必要的档案复制到你的项目中,并使用这些档案。

可在 rel=“noreferer”> 。

警告:回收计划观点可能会改变,可能会有ug。

<>上>

横向清单调查源代码是:

LinearLayoutManager layoutManager
    = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);

RecyclerView myList = findViewById(R.id.my_recycler_view);
myList.setLayoutManager(layoutManager);

现在把它放在你的校准中,正确地点击它,并选定Add为图书馆。

现行主轴是:

 <com.devsmart.android.ui.HorizontalListView
    android:id="@+id/hlistview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />

如果你想用图像进行横向清单调查,那么现在就在活动类别中采用这一代码。

  HorizontalListView hListView = (HorizontalListView) findViewById(R.id.hlistview);
    hListView.setAdapter(new HAdapter(this));


 private class HAdapter extends BaseAdapter {

    LayoutInflater inflater;

    public HAdapter(Context context) {
        inflater = LayoutInflater.from(context);

    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return Const.template.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        HViewHolder holder;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.listinflate, null);
            holder = new HViewHolder();
            convertView.setTag(holder);

        } else {
            holder = (HViewHolder) convertView.getTag();
        }
        holder.img = (ImageView) convertView.findViewById(R.id.image);
        holder.img.setImageResource(Const.template[position]);
        return convertView;
    }

}

class HViewHolder {
    ImageView img;
}

Answer 7

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

<编码>mlistView.setRotation(-90);

然后对孩子进行fl弄,这应当放在通话方法中。你们轮流生育孩子,直截了当:

 mylistViewchild.setRotation(90);

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

 <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>
</com.github.rongi.rotate_layout.layout.RotateLayout>

Answer 8

我的解决办法是简单地使用<条码> 字典>。它是作为<代码>Gallery的中枢,并具有回收观点的内在特征(<代码>ListView)。你在谷歌剧时可能看到类似的做法,只要你处理横向滚动清单。

您仅需要扩大<条码>,并在此实施一 couple:

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: enter image description here

            FrameLayout frameLayout = new FrameLayout(ActivityMap.this);
            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, getPixelsToDP(90));

        int pixels = (int) (dp * scale + 0.5f);

    }

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... :)

答案很多,但如何使用http://developer.android.com/vis/android/widget/HorizontalScrollView.html” rel=“noreferer” Horizontal Scroll View?

Answer 11

您可在支助图书馆使用ReleaserView。回收意见是一份清单,支持:

A layout manager for positioning items
Default animations for common item operations

∗ UNEP/POPS/POPRC.3。

Answer 12

我为解决这一问题做了很多努力。答案很短,没有很好的解决办法,没有凌驾于私人方法之上,也没有这种解决办法。我发现的最好办法是通过扩大<条码>AdapterView来实施。这完全是错的。见我的。缩略语

Answer 13

我不得不对我的一个项目采取同样的做法,我最后也撰写了我自己的文件。我称之为HorzListView,现已成为我的开放来源Aniqroid/strong>图书馆的一部分。

http://aniqroid.sileria.com/doc/api/ (从底层下载或使用权宜计代码项目下载,以看到更多的下载选择:http://code.google.com/p/aniqroid/downloads/list )

班级文件如下:rel=“nofollow”http://aniqroid.sileria.com/doc/api/com/sileria/android/view/HorzListView.html 。

Answer 14

在我的申请中,我使用一个包含线性语言的横向发展意见,该意见的方向是横向的。为了在内部添加图像,我在活动范围内制作图像,并在我的线索中添加图像。例如:

<HorizontalScrollView 
        android:id="@+id/photo_scroll"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:scrollbars="horizontal"
        android:visibility="gone">

        <LinearLayout 
            android:id="@+id/imageview_holder"
            android:layout_width="wrap_content"
            android:orientation="horizontal"
            android:layout_height="match_parent">

        </LinearLayout>
    </HorizontalScrollView>

这对我来说是完美的。在这项活动中,我必须做的是以下法典:

LinearLayout imgViewHolder = findViewById(R.id.imageview_holder);
ImageView img1 = new ImageView(getApplicationContext());
//set bitmap
//set img1 layout params
imgViewHolder.add(img1);
ImageView img2 = new ImageView(getApplicationContext());
//set bitmap
//set img2 layout params
imgViewHolder.add(img2);

正如我说过的那样,我为我工作,我希望这也有助于有些人也希望实现这一目标。

Answer 17

我使用了 devsmart图书馆,但最初向我提出一些问题。最好使用

Answer 18

有一个巨大的图书馆,称为 TwoWayView,它非常容易执行,只是将项目图书馆纳入到你的工作空间,并将之作为图书馆项目添加到你原来的项目,然后采取下列步骤:

First, let s add a style indicating the orientation of the ListView (horizontal or vertical) in (res/values/styles.xml):

<style name="TwoWayView">
    <item name="android:orientation">horizontal</item>
</style>

然后,

在阁下的Lahout XML中,使用以下法典添加《两点意见》:

<org.lucasr.twowayview.TwoWayView 
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:id="@+id/lvItems"
     style="@style/TwoWayView"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:drawSelectorOnTop="false"
     tools:context=".MainActivity" />

最后,仅作正式宣布并处理。名单

TwoWayView lvTest = (TwoWayView) findViewById(R.id.lvItems);

<代码>ListView的所有方法将按惯例在此运作,但只有一种差异,即确定选择模式时,该方法<代码>.setChoiceMode/code>不采用<编码>int。 <代码>enum :ChoiceMode/code>, so list_view.setChoiceMode(ListView.CHOICE_MODE_SINGLE);将.setChoiceMode(ChoiceMode.SINGLE); /或 MultIPLE或NONE。
