RecyclerView with GridView

Question

Once I write a ListView demo, the ListView's items have some different types.

item1:

Text

Pic Pic Pic

item2:

Text

Pic Pic

item3:

Text

Pic Pic Pic

...

So I override the getViewTypeCount() and getItemViewType().It work well. But Now I change to use RecyclerView. Is there a better solution?Please help me.

You might misunderstand what I mean. – Egos Zhang Sep 30 '15 at 08:12
Could you explain your code? Code-only answers are generally not acceptable on StackOverflow, and as such are liable to be deleted. – Wai Ha Lee Oct 01 '15 at 00:49

This is sample, you can create an item view with a textview and nonscrolling gridview

public class NonScrollGridView extends GridView {

    public NonScrollGridView (Context context) {
        super(context);
    }

    public NonScrollGridView (Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public NonScrollGridView (Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Do not use the highest two bits of Integer.MAX_VALUE because they are
        // reserved for the MeasureSpec mode
        int heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightSpec);
        getLayoutParams().height = getMeasuredHeight();


    }
}

Your RecyclerView item view

<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/titleTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginBottom="16dp"/> 

    <com.example.NonScrollGridView 
        android:id="@+id/gridView"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:divider="@android:color/white"/>


</LinearLayout>

thx,but it not good when the NonScrollGridView recycling. So I extends LinearLayout. — Egos Zhang, Sep 30 '15 at 09:13
@EgosZhang you mean you don't want the item be recycled? so what's the point you use recyclerview? — Daniel Martin Shum, Sep 30 '15 at 09:40
NonScrollGridView extends GridView your code doesn't work well when scroll. — Egos Zhang, Sep 30 '15 at 09:52
@EgosZhang OK, I see your point. If you have any other questions just let me know. — Daniel Martin Shum, Sep 30 '15 at 10:01
