Android学习之RecyclerView

标签：android开发   widget   recyclerview   

RecyclerView是android-support-v7-21版本中新增的一个Widget,官方介绍RecyclerView 是 ListView 的升级版本，更加先进和灵活。

开发环境

 - IDE： ADT
 - SDK： Android L

首先在Android SDK Manager上下载Android Support Repository,

它会在sdk/extras/android目录下生成m2repository目录，

进入RecycleView目录。用解压文件打开recyclerview-v7-21.0.0-rc1.aar文件，将claaes.jar改名后放入lib文件夹。

如果想在ADT中关联源代码，可以在libs下新建文件
recycleview.jar.properties 
编辑
src=D:\\adt-bundle-windows-x86_64-20131030\\sdk\\extras\\android\\m2repository\\com\\android\\support\\recyclerview-v7\\21.0.0-rc1\\recyclerview-v7-21.0.0-rc1-sources.jar

右键项目close project,然后open project这样就可以关联源代码了。

创建项目如图

布局文件中使用 RecyclerView

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

package com.leigo.recyclerview;

import android.app.Activity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

/**
 * @ClassName RecyclerViewActivity
 * @Description TODO
 * @author GaoLei
 * @date 2014-7-2
 */
public class RecyclerViewActivity extends Activity {

	private static final String TAG = RecyclerViewActivity.class
			.getSimpleName();

	private RecyclerView mRecyclerView;

	/**
	 * @Method: onCreate
	 * @Description: TODO
	 * @param savedInstanceState
	 * @see android.app.Activity#onCreate(android.os.Bundle)
	 */
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_recycle_view);

		mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);

		LinearLayoutManager layoutManager = new LinearLayoutManager(this);
//		layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
		// 设置布局管理器
		mRecyclerView.setLayoutManager(layoutManager);

		String[] dataset = new String[100];
		for (int i = 0; i < dataset.length; i++) {
			dataset[i] = "item" + i;
		}
		RecyclerAdapter mAdapter = new RecyclerAdapter(dataset);
		mRecyclerView.setAdapter(mAdapter);
	}

Adapter

package com.leigo.recyclerview;

import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.RecyclerView.Adapter;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

/**
 * @ClassName RecyclerAdapter
 * @Description TODO
 * @author GaoLei
 * @date 2014-7-2
 */
public class RecyclerAdapter extends Adapter<RecyclerAdapter.ViewHolder> {
	private String[] mDataset;

	/**
	 * @Description: TODO
	 */
	public RecyclerAdapter(String[] dataset) {
		mDataset = dataset;
	}

	public static class ViewHolder extends RecyclerView.ViewHolder {

		public TextView mTextView;

		/**
		 * @Description: TODO
		 * @param itemView
		 */
		public ViewHolder(View itemView) {
			super(itemView);
			mTextView = (TextView) itemView;
		}
	}

	/**
	 * @Method: getItemCount
	 * @Description: TODO
	 * @return
	 * @see android.support.v7.widget.RecyclerView.Adapter#getItemCount()
	 */
	@Override
	public int getItemCount() {
		return mDataset.length;
	}

	/**
	 * @Method: onBindViewHolder
	 * @Description: TODO
	 * @param holder
	 * @param position
	 * @see android.support.v7.widget.RecyclerView.Adapter#onBindViewHolder(android.support.v7.widget.RecyclerView.ViewHolder,
	 *      int)
	 */
	@Override
	public void onBindViewHolder(ViewHolder holder, int position) {
		holder.mTextView.setText(mDataset[position]);
	}

	/**
	 * @Method: onCreateViewHolder
	 * @Description: TODO
	 * @param parent
	 * @param viewType
	 * @return
	 * @see android.support.v7.widget.RecyclerView.Adapter#onCreateViewHolder(android.view.ViewGroup,
	 *      int)
	 */
	@Override
	public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
		View view = View.inflate(parent.getContext(),
				android.R.layout.simple_list_item_1, null);
		ViewHolder holder = new ViewHolder(view);
		return holder;
	}
}
