最近项目里面用到了底部的弹出提示框，UI小姐姐本着设计样式还是ios的好看原则。设计了一个ios样式的底部弹出提示框。OK OK anyway，类似样式并不少见，实现方式有很多，网上随便找一个吧，还不满大街都是。嗯哼，确实不少。但是 !!! 不是讲代码就是讲布局，或者使用方法挺麻烦。

用的时候还要自己手写这部分代码，麻烦不麻烦？作为一名注定要改变世界的程序猿，你让我天天写这个？这是不能忍的。就没有简单的，快捷的，高效的，一句话就能搞定的吗？

有需求就有产品，所以，这个BottomMenu产生了。GitHub项目地址

先来看下效果：

How to use：

Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:

 allprojects { repositories { ... maven { url 'https://jitpack.io' } } }

Step 2. Add the dependency

 dependencies { compile 'com.github.zhaolei9527:BottomMenu:v1.0.1' }

Activity文件代码：（一句话，有木有?很简单，有木有？）
基本用法：

new BottomMenuFragment(MainActivity.this) .addMenuItems(new MenuItem("从相册选择")) .addMenuItems(new MenuItem("拍照")) .setOnItemClickListener(new BottomMenuFragment.OnItemClickListener() { @Override public void onItemClick(TextView menu_item, int position) { Toast.makeText(MainActivity.this, menu_item.getText().toString().trim(), Toast.LENGTH_SHORT).show(); } }) .show();

带Title用法：

new BottomMenuFragment(MainActivity.this) .setTitle("标题") .addMenuItems(new MenuItem("从相册选择")) .addMenuItems(new MenuItem("拍照")) .setOnItemClickListener(new BottomMenuFragment.OnItemClickListener() { @Override public void onItemClick(TextView menu_item, int position) { Toast.makeText(MainActivity.this, menu_item.getText().toString().trim(), Toast.LENGTH_SHORT).show(); } }) .show();

指定条目样式用法：

new BottomMenuFragment(MainActivity.this) .setTitle("标题") .addMenuItems(new MenuItem("从相册选择", MenuItem.MenuItemStyle.COMMON)) .addMenuItems(new MenuItem("拍照", MenuItem.MenuItemStyle.STRESS)) .setOnItemClickListener(new BottomMenuFragment.OnItemClickListener() { @Override public void onItemClick(TextView menu_item, int position) { Toast.makeText(MainActivity.this, menu_item.getText().toString().trim(), Toast.LENGTH_SHORT).show(); } }) .show();

全部一句话搞定，还有更多功能可以自己发掘一下。

最后看下组件代码:

整体结构为三个文件，BottomMenuFragment为弹出主体内容，MenuItem为条目对象的POJO，MenuItemAdapter顾名思义是条目的适配器。代码逻辑实现方法其实挺简单，大同小异，只不过对于代码进行封装使操作更加便捷，简单且迅速。
BottomMenuFragment文件：

public class BottomMenuFragment extends DialogFragment { private final String TAG = "BottomMenuFragment"; private Activity context; private OnItemClickListener mOnItemClickListener; private boolean showTitle = false; private String BottomTitle = ""; public BottomMenuFragment(Activity context) { this.context = context; } private List<MenuItem> menuItemList = new ArrayList<MenuItem>(); public List<MenuItem> getMenuItems() { return menuItemList; } public void addMenuItems(List<MenuItem> menuItems) { this.menuItemList.addAll(menuItems); } public BottomMenuFragment addMenuItems(MenuItem menuItems) { menuItemList.add(menuItems); return this; } public BottomMenuFragment setTitle(String BottomTitle) { showTitle = true; this.BottomTitle = BottomTitle; return this; } public void show() { this.show(context.getFragmentManager(), "BottomMenuFragment"); } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE); getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//设置背景透明 getDialog().getWindow().setWindowAnimations(R.style.menu_animation);//添加一组进出动画 View view = inflater.inflate(R.layout.fragment_bottom_menu, container, false); //view.setAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.menu_appear));//添加一个加载动画，这样的问题是没办法添加消失动画，有待进一步研究 ((TextView) view.findViewById(tv_cancel)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.i(TAG, "onClick: tv_cancel"); BottomMenuFragment.this.dismiss(); } }); if (showTitle) { menuItemList.add(0, new MenuItem(BottomTitle, MenuItem.MenuItemStyle.COMMON)); } ListView lv_menu = (ListView) view.findViewById(R.id.lv_menu); MenuItemAdapter menuItemAdapter = new MenuItemAdapter(getActivity().getBaseContext(), this.menuItemList); lv_menu.setAdapter(menuItemAdapter); lv_menu.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i(TAG, "onClick: "); if (mOnItemClickListener != null) { if (showTitle) { if (position == 0) { return; } } TextView menu_item = (TextView) view.findViewById(R.id.menu_item); mOnItemClickListener.onItemClick(menu_item, position); dismiss(); } } }); return view; } public interface OnItemClickListener { void onItemClick(TextView menu_item, int position); } public BottomMenuFragment setOnItemClickListener(@Nullable OnItemClickListener listener) { mOnItemClickListener = listener; return this; } @Override public void onDestroyView() { super.onDestroyView(); Log.i(TAG, "onDestroyView: "); } @Override public void onAttach(Context context) { super.onAttach(context); Log.i(TAG, "onAttach: "); } @Override public void onDetach() { super.onDetach(); Log.i(TAG, "onDetach: "); } @Override public void onStart() { super.onStart(); Log.i(TAG, "onStart: "); //设置弹出框宽屏显示，适应屏幕宽度 DisplayMetrics dm = new DisplayMetrics(); getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm); getDialog().getWindow().setLayout(dm.widthPixels, getDialog().getWindow().getAttributes().height); //移动弹出菜单到底部 WindowManager.LayoutParams wlp = getDialog().getWindow().getAttributes(); wlp.gravity = Gravity.BOTTOM; // wlp.width = WindowManager.LayoutParams.MATCH_PARENT; getDialog().getWindow().setAttributes(wlp); } @Override public void onStop() { this.getView().setAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.menu_disappear)); super.onStop(); } }

MenuItemAdapter文件：

public class MenuItemAdapter extends BaseAdapter { private Context context;//运行上下文 private LayoutInflater listContainer; //视图容器 private List<MenuItem> menuItems; public MenuItemAdapter(Context _context, List<MenuItem> _menuItems){ this.context = _context; this.listContainer = LayoutInflater.from(_context); this.menuItems = _menuItems; } @Override public int getCount() { return this.menuItems.size(); } @Override public Object getItem(int position) { if(position >= menuItems.size() || position < 0) { return null; } else { return menuItems.get(position); } } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View view = convertView; if(convertView == null) { view = listContainer.inflate(R.layout.menu_item, null); } MenuItem menuItem = menuItems.get(position); TextView textView = (TextView) view.findViewById(R.id.menu_item); textView.setText(menuItem.getText()); if(menuItems.size() == 1) { textView.setBackgroundResource(R.drawable.bottom_menu_btn_selector); } else if(position == 0) { textView.setBackgroundResource(R.drawable.bottom_menu_top_btn_selector); } else if(position < menuItems.size() - 1) { textView.setBackgroundResource(R.drawable.bottom_menu_mid_btn_selector); } else { textView.setBackgroundResource(R.drawable.bottom_menu_bottom_btn_selector); } if(menuItem.getStyle() == MenuItem.MenuItemStyle.COMMON) { textView.setTextColor(ContextCompat.getColor(context, R.color.bottom_menu_btn_text_commom_color)); } else { textView.setTextColor(ContextCompat.getColor(context, R.color.bottom_menu_btn_text_stress_color)); } return view; } }

MenuItem文件：

public class MenuItem { public MenuItem() { } /** * @param _item_name 菜单项名称 * @param _text 菜单项显示内容 * @param _style 菜单类型 */ public MenuItem(String _item_name, String _text, MenuItemStyle _style) { this.item_name = _item_name; this.text = _text; this.style = _style; } public MenuItem(String _text, MenuItemStyle _style) { this.text = _text; this.style = _style; } public MenuItem(String _text) { this.text = _text; } private String item_name; private String text; private MenuItemStyle style = MenuItemStyle.COMMON; public String getItem_name() { return item_name; } public String getText() { return text; } public MenuItemStyle getStyle() { return style; } public void setItem_name(String item_name) { this.item_name = item_name; } public void setText(String text) { this.text = text; } /** * @param style 菜单类型 */ public void setStyle(MenuItemStyle style) { this.style = style; } public enum MenuItemStyle { COMMON, STRESS } }

总结

代码整体满足了一句话搞定高仿ios底部弹出提示框的功能，当然，

有了需求才有了功能，有了想法才有了创作，你的反馈会是使我进步的最大动力。

觉得还不够方便？还想要什么功能？告诉我！欢迎反馈，欢迎Star。源码入口：BottomMenu-GitHub项目地址
