配置 build.gradle：

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

在主页添加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[]{

android:text="你是我的小呀小苹果,你是我的小呀小苹果,你是我的小呀小苹果,你是我的小呀小苹果你是我的小呀小苹果,你是我的小呀小苹果" />
</LinearLayout>

效果图



主要是添加分享元素android:transitionName=”share”，在列表页和详情页的xml的ImageView布局文件中。

最终效果



本效果只支持API21+，大家要想实现这个效果的可以参考一下。
