RecyclerView的基本创建

线性显示类似于listview：

线性宫格显示类似于grid view：

用线性宫格显示类似于瀑布流：

结构图：

测试代码：

activity_main.xml：

 <RelativeLayout 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.support.v7.widget.RecyclerView

         android:id="@+id/recycler_view"

         android:layout_width="match_parent"

         android:layout_height="match_parent"

         android:layout_centerHorizontal="true"

         android:layout_centerVertical="true" />

 </RelativeLayout>

MainActivity.java：

NormalRecyclerViewAdapter.java：

     @Override

     }

     @Override

         return new NormalTextViewHolder(mLayoutInflater.inflate(

                 android.R.layout.simple_list_item_1, null));

     }

     @Override

     public void onBindViewHolder(NormalTextViewHolder holder, int position) {

             holder.mTextView.setText(mTitles[position]);

     }

     public static class NormalTextViewHolder extends ViewHolder {

         TextView mTextView;

         public NormalTextViewHolder(View view) {

             super(view);

             mTextView=(TextView) view.findViewById(android.R.id.text1);

                 @Override

                 public void onClick(View v) {

                     Log.d("NormalTextViewHolder", "onClick--> position = "

                             + getPosition());
