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
