Android BottomSheet:List列表或Grid网格展示(3)




Android BottomSheet:List列表或Grid网格展示(3)

BottomSheet可以显示多种样式的底部弹出面板风格,比如常见的List列表样式或者Grid网格样式,以一个例子说明。
先写一个布局,该布局作为Activity的布局加载,BottomSheet将从此Activity的底部弹出弹入。布局中只有两个button按钮,分别触发List或者Grid面板:

<?xml version="1.0" encoding="utf-8"?>
<com.flipboard.bottomsheet.BottomSheetLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/bottomsheet"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/root"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="end"
        android:orientation="vertical"
        android:padding="16dp">

        <Button
            android:id="@+id/list_button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/list_button" />

        <Button
            android:id="@+id/grid_button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/grid_button" />

    </LinearLayout>

</com.flipboard.bottomsheet.BottomSheetLayout>


上层Java代码:

package com.flipboard.bottomsheet.sample;

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

import com.flipboard.bottomsheet.BottomSheetLayout;
import com.flipboard.bottomsheet.R;
import com.flipboard.bottomsheet.commons.MenuSheetView;

/**
 * Activity demonstrating the use of {@link MenuSheetView}
 */
public class MenuActivity extends AppCompatActivity {

    protected BottomSheetLayout bottomSheetLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_menu);
        bottomSheetLayout = (BottomSheetLayout) findViewById(R.id.bottomsheet);
        bottomSheetLayout.setPeekOnDismiss(true);
        findViewById(R.id.list_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //显示列表样式菜单
                //传入一个MenuSheetView.MenuType.LIST的值,标明弹出面板样式
                showMenuSheet(MenuSheetView.MenuType.LIST);
            }
        });
        findViewById(R.id.grid_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //弹出网格样式的面板
                showMenuSheet(MenuSheetView.MenuType.GRID);
            }
        });
    }

    private void showMenuSheet(final MenuSheetView.MenuType menuType) {
        MenuSheetView menuSheetView =
                new MenuSheetView(MenuActivity.this, menuType, "请选择...", new MenuSheetView.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(MenuActivity.this, item.getTitle(), Toast.LENGTH_SHORT).show();

                        //因为点击了面板中的某一项,关闭这个面板
                        if (bottomSheetLayout.isSheetShowing()) {
                            bottomSheetLayout.dismissSheet();
                        }

                        //假设用户选择以另外一种方式打开
                        //则重新切换样式
                        if (item.getItemId() == R.id.reopen) {
                            showMenuSheet(menuType == MenuSheetView.MenuType.LIST ? MenuSheetView.MenuType.GRID : MenuSheetView.MenuType.LIST);
                        }

                        return true;
                    }
                });

        //此处构造展示出来的面板选项条目的数据源
        //从menu菜单的数据创建
        //类似适配器
        menuSheetView.inflateMenu(R.menu.create);

        //不要忘记这段代码,否则显示不出来
        bottomSheetLayout.showWithSheetView(menuSheetView);
    }
}



BottomSheet的数据源是从res/menu/下给出的菜单数据构造item。本例中用到的res/menu/create.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:icon="@mipmap/ic_launcher"
        android:title="@string/document" />
    <item
        android:icon="@mipmap/ic_launcher"
        android:title="@string/spreadsheet" />
    <item
        android:icon="@mipmap/ic_launcher"
        android:title="@string/folder" />

    <item
        android:id="@+id/menu_subheader"
        android:title="子菜单">
        <menu>
            <item
                android:id="@+id/navigation_sub_item_1"
                android:icon="@mipmap/ic_launcher"
                android:title="@string/upload_photos" />
            <item
                android:id="@+id/navigation_sub_item_2"
                android:icon="@mipmap/ic_launcher"
                android:title="@string/use_camera" />
        </menu>
    </item>
    <item
        android:id="@+id/reopen"
        android:icon="@mipmap/ic_launcher"
        android:title="@string/reopen" />

</menu>



代码运行结果->
