当我们创建时,RecyclerView.Adapter我们必须指定ViewHolder将与适配器绑定.

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {

    private String[] mDataset;

    public MyAdapter(String[] myDataset) {
        mDataset = myDataset;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView mTextView;
        public ViewHolder(TextView v) {
            super(v);
            mTextView = v;
        }
    }

    @Override
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.some_layout, parent, false);

        //findViewById...

        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.mTextView.setText(mDataset[position]);
    }

    @Override
    public int …

我有以下布局：

<LinearLayout 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:orientation="vertical"
    tools:context="com.example.mkallingal.freakingnav.CardsListFragment">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@color/darktext"
        android:layout_marginBottom="6dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Cards Listing" />

    <android.support.v7.widget.RecyclerView android:layout_height="match_parent" android:layout_width="match_parent" android:id="@+id/rvCardsList"
        android:scrollbars="vertical" tools:listitem="@layout/recycler_item_layout">
    </android.support.v7.widget.RecyclerView>
</LinearLayout>

问题是 TextView 总是粘在顶部，而 RecyclerView 占用屏幕上的剩余空间。我可以水平滚动 recyclerview，但 TextView 只是停留在那里。我如何解决这个问题？
