**AndroidSweetSheet：ViewPager的实现（2）**

附录文章9说明了AndroidSweetSheet典型的列表样式实现，本文写一个例子，说明AndroidSweetSheet以翻页的ViewPager样式实现。本例所需的布局文件和附录文章9相同，只是上层Java代码不同而已：

package zhangphil.demo;
    
    import android.graphics.Color;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.RelativeLayout;

    import com.mingle.entity.MenuEntity;
    import com.mingle.sweetpick.DimEffect;
    import com.mingle.sweetpick.SweetSheet;
    import com.mingle.sweetpick.ViewPagerDelegate;
    
    import java.util.ArrayList;
    
    
    public class MainActivity extends AppCompatActivity {
    
        private SweetSheet mSweetSheet;
        private RelativeLayout rl;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            rl = (RelativeLayout) findViewById(R.id.root);
    
            findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    if (mSweetSheet.isShow())
                        mSweetSheet.dismiss();
                    else
                        mSweetSheet.show();
                }
            });
    
            setupViewpager();
        }
    
        private void setupViewpager() {
            mSweetSheet = new SweetSheet(rl);
    
            final ArrayList<MenuEntity> list = new ArrayList<>();
            for (int i = 0; i < 100; i++) {
                MenuEntity menuEntity = new MenuEntity();
                menuEntity.iconId = R.mipmap.ic_launcher;
                menuEntity.titleColor = Color.RED;
                menuEntity.title = "zhang phil @ csdn " + i;
                list.add(menuEntity);
            }
    
            // SweetSheet 控件,根据 rl 确认位置
            mSweetSheet = new SweetSheet(rl);
    
            //设置数据源 (数据源支持设置 list 数组,也支持从菜单中获取)
            //如果是从菜单中加载，那么是 .setMenuList(R.menu.menu_sweet);
            mSweetSheet.setMenuList(list);
    
            //从menu 中设置数据源
            //mSweetSheet.setMenuList(R.menu.menu_sweet);
    
            //ViewPager样式的底部面板
            mSweetSheet.setDelegate(new ViewPagerDelegate());
    
            mSweetSheet.setBackgroundEffect(new DimEffect(10f));
            mSweetSheet.setOnMenuItemClickListener(new SweetSheet.OnMenuItemClickListener() {
                @Override
                public boolean onItemClick(int position, MenuEntity menuEntity) {
    
                    Toast.makeText(MainActivity.this, menuEntity.title + "  " + position, Toast.LENGTH_SHORT).show();
    
                    return true;
                }
            });
        }
    
        /**

                    ((RecyclerViewDelegate) mSweetSheet.getDelegate()).notifyDataSetChanged();
