AndroidSweetSheet：ViewPager的實作（2）

附錄文章9說明了AndroidSweetSheet典型的清單樣式實作，本文寫一個例子，說明AndroidSweetSheet以翻頁的ViewPager樣式實作。本例所需的布局檔案和附錄文章9相同，隻是上層Java代碼不同而已：

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.RelativeLayout;
import android.widget.Toast;

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,根據 rl 确認位置
        mSweetSheet = new SweetSheet(rl);

        //設定資料源 (資料源支援設定 list 數組,也支援從菜單中擷取)
        //如果是從菜單中加載，那麼是 .setMenuList(R.menu.menu_sweet);
        mSweetSheet.setMenuList(list);

        //從menu 中設定資料源
        //mSweetSheet.setMenuList(R.menu.menu_sweet);

        //ViewPager樣式的底部面闆
        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;
            }
        });
    }

    /**
    private void setupRecyclerView() {
        final ArrayList<MenuEntity> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            MenuEntity menuEntity = new MenuEntity();
            menuEntity.iconId = R.mipmap.ic_launcher;
            menuEntity.titleColor = Color.RED;
            menuEntity.title = "zhang phil @ csdn " + i;
            list.add(menuEntity);
        }

        //如果是從菜單中加載，那麼是 .setMenuList(R.menu.menu_sweet);
        mSweetSheet.setMenuList(list);

        //根據設定不同的 Delegate 來顯示不同的風格.
        mSweetSheet.setDelegate(new RecyclerViewDelegate(true));

        //根據設定不同Effect 來顯示背景效果
        // BlurEffect:模糊效果.
        // DimEffect 變暗效果
        mSweetSheet.setBackgroundEffect(new DimEffect(10f));

        //設定點選事件
        mSweetSheet.setOnMenuItemClickListener(new SweetSheet.OnMenuItemClickListener() {
            @Override
            public boolean onItemClick(int position, MenuEntity menuEntity) {
                //即時改變目前項的顔色
                list.get(position).titleColor = Color.GREEN;

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

                Toast.makeText(MainActivity.this, menuEntity.title + "  " + position, Toast.LENGTH_SHORT).show();

                //根據傳回值, true 會關閉 SweetSheet ,false 則不會.
                return false;
            }
        });
    }
    **/

    @Override
    public void onBackPressed() {
        if (mSweetSheet.isShow()) {
            mSweetSheet.dismiss();
        } else {
            super.onBackPressed();
        }
    }
}
