试图让自定义列表视图中的小型星级评定器工作



我有一个正在构建的自定义列表视图，带有一个星型栏。在我尝试添加星栏之前，我的自定义列表视图已经工作。我得到的力量接近是：

我的自定义适配器是：

public class TasteInfoAdapter extends ArrayAdapter<TasteInfo>{
    Context context; 
    int layoutResourceId;    
    List<TasteInfo> data = null;
    public TasteInfoAdapter(Context context, int layoutResourceId, List<TasteInfo> data) {
        super(context, layoutResourceId, data);
        this.layoutResourceId = layoutResourceId;
        this.context = context;
        this.data = data;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        beerHolder holder = null;
        if(row == null)
        {
            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);
            holder = new beerHolder();
            holder.txtTaste = (TextView)row.findViewById(R.id.breweryName);
            holder.txtRate = (TextView)row.findViewById(R.id.breweryRate);
            holder.txtBar = (RatingBar) row.findViewById(R.id.starbar);
            row.setTag(holder);
        }
        else
        {
            holder = (beerHolder)row.getTag();
        }
        TasteInfo beer = data.get(position);
        holder.txtTaste.setText(beer.taste);
        holder.txtRate.setText(beer.rate);
        holder.numHolder= Float.parseFloat(beer.rate);
        holder.txtBar.setNumStars(5);
        holder.txtBar.setRating(holder.numHolder);
        return row;
    }
    static class beerHolder
    {
        TextView txtTaste;
        TextView txtRate;
        RatingBar txtBar;
        Float numHolder;
    }
}

我的列表视图项的xml是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <TextView
        android:id="@+id/breweryName"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />
    <linearLayout
        android:orientation="horizontal"
        >

        <RatingBar android:id="@+id/starbar"
    style="?android:attr/ratingBarStyleIndicator"
    android:layout_marginLeft="5dip"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical" />
        <TextView
            android:id="@+id/breweryRate"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:text="Large Text"
            android:gravity="right"
            android:textAppearance="?android:attr/textAppearanceLarge" />
    </linearLayout>
</LinearLayout>

更新：

修正了在线性布局中不放宽度或高度的问题，现在我可以接近这个力：

我正在努力实现的是：

https://i.stack.imgur.com/VUSRP.jpg

   <linearLayout
    android:orientation="horizontal"
    >

你错过了两个强制性属性：

android:layout_width="wrap_content"
android:layout_height="wrap_content"
