列表视图中的水平ScrollView项目Android

Question

我有一个包含20行的列表视图,我想为scrollview列表视图中的每个行项设置一个水平,因为每行包含多个项目.

这是我的代码:

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

    <HorizontalScrollView
        android:id="@+id/hor_scroll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="none" >

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

</RelativeLayout>

内行布局,可以连续多次复制

<ImageView
    android:id="@+id/icon"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_marginRight="6.0dip"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:gravity="center_vertical"
    android:text="Example Value"
    android:textAppearance="?android:textAppearanceMedium" />

BaseAdapter

public class HorizontalListViewAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<ArrayList<DwivediJi>> dataSet;


    public HorizontalListViewAdapter(Context context) {
        this.context = context;
    }

    @Override
    public int getCount() {
        return 20;
    }

    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.horizontal_list_item, null,false);

        LinearLayout mainLinnerLayout=(LinearLayout)convertView.findViewById(R.id.mainLinear);

         for (int i = 0; i <5; i++) {
             View additionView = inflater.inflate(R.layout.inner_layout_file, null,false);
             LinearLayout innerLinnerLayout=(LinearLayout)additionView.findViewById(R.id.inner_layout);
             mainLinnerLayout.addView(innerLinnerLayout);
        } 
        return convertView;
    }

    class ViewHolder {
        TextView tv_titleExample;
        HorizontalScrollView hzView;
        LinearLayout linear_layout,main_linear_layout;
    }
}

我的问题

看看附带的截图.我的问题是每行中一次显示多个视图.

我希望一次只能向用户显示一个视图,其余用户要做的就是从左到右或从右到左滑动.

注意：不是一个理想的解决方案，但应该提供您想要的。另一个注意：这可能会使您的列表视图稍微卡顿，具体取决于布局复杂性

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.horizontal_list_item, null,false);

        LinearLayout mainLinnerLayout=(LinearLayout)convertView.findViewById(R.id.mainLinear);

         for (int i = 0; i <5; i++) {
             View additionView = inflater.inflate(R.layout.inner_layout_file, null,false);
             LinearLayout innerLinnerLayout=(LinearLayout)additionView.findViewById(R.id.inner_layout);

             // If the width varies for each innerLinnerLayout, then remove the if block & always calculate padding value
             // padding is an integer initialized to -1 in the constructor
             if (padding == -1) {
                 int width = context.getResources().getDisplayMetrics().widthPixels;
                 innerLinnerLayout.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
                 padding = width - additionView.getMeasuredWidth();
             }
             // I've set padding to right only, but you could center it by giving left and right padding of value=(padding/2)
             innerLinnerLayout.setPadding(0, 0, padding, 0);
             mainLinnerLayout.addView(innerLinnerLayout);
        } 
        return convertView;
    }
