license JCenter

效果如下

引入方法:

dependencies {

     implementation 'com.noober.floatmenu:common:1.0.4'
}

使用说明

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)

创建菜单:

注意点:

显示floatmenu有两种方法:

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);
		}
	});
new FloatMenu(this, view) 与 new FloatMenu(this)区别

使用第二种方法创建对象在,必须重写dispatchTouchEvent
