代码

MainActivity.java

public class MainActivity extends AppCompatActivity {


    ListView listView;
    MyAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView= (ListView) findViewById(R.id.listview);
        adapter=new MyAdapter(MainActivity.this);
        listView.setAdapter(adapter);

    }
}

MyAdapter.java
注意：点击图片会有转场动画出现，仔细看onClick的写法

public class MyAdapter extends BaseAdapter {

    private Context context;
    List list=new ArrayList();

    MyAdapter(Context context) {
        this.context = context;
        list.add(R.drawable.anim1);
        list.add(R.drawable.anim2);
        list.add(R.drawable.anim3);
//        list.add(R.drawable.anim4);
//        list.add(R.drawable.anim5);
//        list.add(R.drawable.anim6);

    }
    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;
        if (convertView == null) {
            convertView =  LayoutInflater.from(context).inflate(R.layout.item, parent, false);
            holder = new ViewHolder();
            holder.imageView = (ImageView) convertView.findViewById(R.id.img_avatar);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.imageView.setImageResource((int)list.get(position));
        holder.imageView.setOnClickListener(new View.OnClickListener() {
            @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
            @Override
            public void onClick(View v) {
                //动画在这里
                ActivityOptions options =
                        ActivityOptions.makeSceneTransitionAnimation((Activity) context, v, context.getString(R.string.image_transition_name));
                Intent intent=new Intent(context,DtailActivity.class);
                intent.putExtra(DtailActivity.EXTRA_IMAGE,(int)getItem(position) );
                context.startActivity(intent,options.toBundle());
            }
        });
        return convertView;
    }

    private class ViewHolder {
        ImageView imageView;
    }
}

DtailActivity.java

public class DtailActivity extends AppCompatActivity {

    public static final java.lang.String EXTRA_IMAGE = DtailActivity.class.getSimpleName() + ".IMAGE";
    ImageView imgAvatar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dtail);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        imgAvatar= (ImageView) findViewById(R.id.img_avatar);
        imgAvatar.setImageResource(getIntent().getExtras().getInt(EXTRA_IMAGE));

    }

}

第二个页面布局文件
关键：注意imageView的 android:transitionName=”@string/image_transition_name”
