配置 build.gradle：

  compile 'com.android.support:recyclerview-v7:23.3.0'
  compile 'com.squareup.picasso:picasso:2.3.2'

在主页加入RecylerView

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        recyclerView = (RecyclerView) findViewById(R.id.recylerview);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new GridLayoutManager(this, 3));
        recyclerView.setAdapter(adapter = new PicassoAdapter(this));
        adapter.replaceAll(getData());
    }

    private ArrayList<String> getData() {
        ArrayList<String> list = new ArrayList<>();
        for (int i = 0; i < ImageUtil.imageUrls.length; i++) {
            list.add(ImageUtil.imageUrls[i]);
        }
        return list;
    }

初始化数据：

package com.example.wangchang.testpicasso;

/**

public class ImageUtil {

    public final static String[] imageUrls = new String[]{

效果图

主要是加入分享元素android:transitionName=”share”。在列表页和详情页的xml的ImageView布局文件里。

终于效果

本效果仅仅支持API21+。大家要想实现这个效果的能够參考一下。
