无需一切权限，不受各种国产ROM限制，默认可以显示的应用内悬浮窗。
- 应用内显示，无需申请任何权限
- 应用内显示，所有机型都可以默认显示悬浮窗，无需引导用户做更多设置
- 支持拖拽
- 超出屏幕限制移动
- 可自动吸附到屏幕边缘
- 可向左右边缘隐藏一半
核心类共三个：

应用例子：
在基础类的地方创建一个全局的CFloatingManager.FloatingImp floatingImp对象，目的是为了保持对象唯一，然后在各个子类中进行引用：
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (null == floatingImp) {
floatingImp = CFloatingManager.build()
.setLayout(R.layout.en_floating_view)//设置布局
.setInitViews(new CFloatingView.IFloatingViews() { // 可以在此处对布局内的子控件单独进行控制，todo：设置点击事件，则会影响到拖动事件
@Override
public void onInitViews(CFloatingView cFloatingView) {
cFloatingView.view.findViewById(R.id.icon).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(TestActivity.this, "点击了icon", Toast.LENGTH_SHORT).show();
}
});
}
})
.setListener(new CFloatingView.MagnetViewListener() {//设置监听事件
@Override
public void onRemove(CFloatingView cFloatingView) {
Toast.makeText(TestActivity.this, "我没了", Toast.LENGTH_SHORT).show();
}
@Override
public void onClick(CFloatingView cFloatingView) {
Toast.makeText(TestActivity.this, "点到我了", Toast.LENGTH_SHORT).show();
}
@Override

Toast.makeText(TestActivity.this, "又出现了", Toast.LENGTH_SHORT).show();
}
@Override
public void onEndHide(CFloatingView cFloatingView) {
((ImageView)cFloatingView.view.findViewById(R.id.icon)).setImageResource(R.drawable.jy_sdk_float_window_transparent);
Toast.makeText(TestActivity.this, "隐藏了一半", Toast.LENGTH_SHORT).show();
}
})
.setIsMovable(true)//控制是否可移动
.setIsHideEdge(true)//控制是否需要隐藏
.create();//创建实体
}
}
@Override
protected void onStart() {
super.onStart();
floatingImp.attach(this);//绑定实体至页面
}
@Override
protected void onStop() {
super.onStop();
floatingImp.detach(this);//移除实体离开页面
}
en_floating_view.xml
<?xml version="1.0" encoding="utf-8"?>
