A menu style pop-up window that mimics WeChat。仿微信的长按菜单。
dependencies{implementation 'com.noober.floatmenu:common:1.0.4' } 使用方法1: Activity 重写dispatchTouchEvent，并且新建一个Point对象，show的时候传入改对象
private Point point = new Point(); @Override public boolean dispatchTouchEvent(MotionEvent ev){if(ev.getAction() == MotionEvent.ACTION_DOWN){point.x = (int) ev.getRawX(); point.y = (int) ev.getRawY()} return super.dispatchTouchEvent(ev)} 调用：
listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){@Override public void onItemClick(AdapterView<?> parent, View view, int position, long id){FloatMenu floatMenu = new FloatMenu(MainActivity.this); floatMenu.items("菜单1", "菜单2", "菜单3"); floatMenu.show(point)} }); 使用方法2: 不需要重写dispatchTouchEvent，但是需要在初始化的时候传入所点击的view，floatment初始化必须在点击事件外部
final FloatMenu floatMenu = new FloatMenu(this, btn1); floatMenu.items("菜单1", "菜单2", "菜单3"); floatMenu.setOnItemClickListener(new FloatMenu.OnItemClickListener(){@Override public void onClick(View v, int position){Toast.makeText(MainActivity.this, "菜单"+position, Toast.LENGTH_SHORT).show()} }); 设置菜单的方式: 1.代码设置
floatMenu.items("菜单1", "菜单2", "菜单3"); ... List<String> list = new ArrayList<>(); list.add("菜单1"); list.add("菜单2"); list.add("菜单3"); floatMenu.items(list); 2.代码设置（范型继承MenuItem即可） List<TestMenuItem> itemList = new ArrayList<>(); TestMenuItem menuItem = new TestMenuItem(); menuItem.setItem("菜单1"); itemList.add(menuItem); TestMenuItem menuItem2 = new TestMenuItem(); menuItem2.setItem("菜单2"); itemList.add(menuItem2); TestMenuItem menuItem3 = new TestMenuItem(); menuItem3.setItem("菜单2"); itemList.add(menuItem3); floatMenu.items(itemList); 3.menu.xml设置
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item app:menu_title="Send to Chat" app:icon = "@drawable/brush"></item> <item app:menu_title="Add to Favorites" app:icon = "@drawable/barrage"/> <item app:menu_title="Delete" app:icon = "@drawable/clock"/> <item app:menu_title="More" app:icon = "@drawable/collection"/> </menu> floatMenu.inflate(R.menu.popup_menu); 方法都提供参数设置菜单的宽度:
public void items(List<T extends MenuItem> itemList, int itemWidth) public void items(int itemWidth, String... items) public void inflate(int menuRes, int itemWidth) floatmenu.show(point)与floatmenu.show()的区别 区别在于，创建floatmenu对象的位置，如果使用第2种方法，创建floatmenu必须在点击事件的外面， 第一种则没有这种限制，如下所示:
final FloatMenu floatMenu = new FloatMenu(this, btn2); floatMenu.inflate(R.menu.popup_menu); floatMenu.setOnItemClickListener(new FloatMenu.OnItemClickListener(){@Override public void onClick(View v, int position){Toast.makeText(MainActivity.this, "菜单"+position, Toast.LENGTH_SHORT).show()} }); listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){@Override public void onItemClick(AdapterView<?> parent, View view, int position, long id){FloatMenu floatMenu = new FloatMenu(MainActivity.this); floatMenu.items("菜单1", "菜单2", "菜单3"); floatMenu.show(point)} }); 使用第二种方法创建对象在，必须重写dispatchTouchEvent
