最近业务需求需要我们直播返回或者退出直播间时，开一个小窗口在全局继续直播视频，先看效果图。
调研了一下当下主流直播平台，斗鱼BiLiBiLi等app,都是用windowManger 做的即通过windowManger add一个全局的view,可以申请权限悬浮在所有应用之上以此来实现全局悬浮窗
ok,分析完实现原理我们就开始撸代码了
实现悬浮窗难点
１：权限申请：一个是6.0及以后要用户手动授权，因为悬浮窗权限属于高危权限，二是因为MIUI,底层修改了权限，所以在小米手机上需要特殊处理，还有就是8.0以后权限的定义类型变了下面有代码会详解这块
２：对于悬浮窗touch 事件的监听，比如点击事件和touch事件，如果同事监听那么setOnclickListener就没有效果了，需要区别点击和touch,还有就是拖动小窗口移动位置，这里是指针对整个窗体即设置touch事件又设置点击事件会有冲突
３：直播组件的初始化，即全局单例的直播窗口，可以是自己封装一个自定义View,这个因各自的直播ＳＤＫ而定，我这用的sdk在插件里，所以实现起来比较麻烦，但是一般直播sdk(阿里云或者七牛)都可以用同一个直播组件对象，即在直播页面销毁或者返回时把对象传递到小窗口里，实现无缝衔接开启小窗口直播，不需要重新加载,这里用EventBus发个消息或者广播都可以实现
一：权限申请
首先要在清单文件即AndroidManifest文件声明 悬浮窗权限
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />然后我们悬浮窗触发的时机是在直播页面返回的时候，那也就是说可以在onDestory()或者finsh()时候去做权限申请
注：因为6.0以后是高危权限，所以代码是拿不到权限的，需要跳到权限申请列表让用户授权
if (isLiveShow) {
if (Build.VERSION.SDK_INT >= 23) {
if (!Settings.canDrawOverlays(getContext())) {
//没有悬浮窗权限,跳转申请
Toast.makeText(getApplicationContext(), "请开启悬浮窗权限", Toast.LENGTH_LONG).show();
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
startActivity(intent);
} else {
initLiveWindow();
}
} else {
//6.0以下 只有MUI会修改权限
if (MIUI.rom()) {
if (PermissionUtils.hasPermission(getContext())) {
initLiveWindow();
} else {
MIUI.req(getContext());
}
} else {
initLiveWindow();
}
}
}而低版本一般是不需要用户授权的除了MIUI,所以我们需要先判断是否是MIUI系统，然后判断MIUI版本，然后不同的版本对应不同的权限申请姿势，如果你不这么做，那么恭喜你在低版本(低于6.0)的小米手机上不是返回跳转权限崩溃，因为底层改了授权列表类或者是根本不会跳授权没有反应，
//6.0以下 只有MUI会修改权限
if (MIUI.rom()) {
if (PermissionUtils.hasPermission(getContext())) {
initLiveWindow();
} else {
MIUI.req(getContext());
}
} else {
initLiveWindow();
}先判断是否是MIUI系统
public static boolean rom() {
return Build.MANUFACTURER.equals("Xiaomi");
}然后根据不同版本，不同的授权姿势

}二：弹窗的初始化，以及touch事件的监听
首先我们需要明白一点 windowManger的源码，只有三个方法
package android.view;
/** Interface to let you add and remove child views to an Activity. To get an instance
* of this class, call {@link android.content.Context#getSystemService(java.lang.String) Context.getSystemService()}.
*/
public interface ViewManager
{
/**
* Assign the passed LayoutParams to the passed View and add the view to the window.
* <p>Throws {@link android.view.WindowManager.BadTokenException} for certain programming
* errors, such as adding a second view to a window without removing the first view.
* <p>Throws {@link android.view.WindowManager.InvalidDisplayException} if the window is on a
* secondary {@link Display} and the specified display can't be found
* (see {@link android.app.Presentation}).
* @param view The view to be added to this window.
* @param params The LayoutParams to assign to view.
*/
public void addView(View view, ViewGroup.LayoutParams params);
public void updateViewLayout(View view, ViewGroup.LayoutParams params);
public void removeView(View view);
}看名字就知道，增加，更新，删除
然后我们需要自定义一个View 通过addView 添加到windowManger 上，先上关键代码
windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
//赋值WindowManager&LayoutParam.
params = new WindowManager.LayoutParams();
//设置type.系统提示型窗口，一般都在应用程序窗口之上.
if (Build.VERSION.SDK_INT >= 26) {//8.0新特性
params.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
}
//设置效果为背景透明.
params.format = PixelFormat.RGBA_8888;
//设置flags.不可聚焦及不可使用按钮对悬浮窗进行操控.
params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
//设置窗口坐标参考系
params.gravity = Gravity.LEFT | Gravity.TOP;
//用于检测状态栏高度.
int resourceId = context.getResources().getIdentifier("status_bar_height",
"dimen","android");
if (resourceId > 0) {
statusBarHeight = context.getResources().getDimensionPixelSize(resourceId);
}
offset = DimensionUtils.dp2px(context, 2);//移动偏移量
//设置原点
params.x = getScreenWidth(context) - DimensionUtils.dp2px(context, 170);
params.y = getScreenHeight(context) - DimensionUtils.dp2px(context, 100+72) ;
//设置悬浮窗口长宽数据.
params.width = DimensionUtils.dp2px(context, 170);
params.height = DimensionUtils.dp2px(context, 100);
//获取浮动窗口视图所在布局.
toucherLayout = new FrameLayout(context);
mPlayer = new Player();
gsVideoView = new GSVideoView(context);
/**
* 设置视频View
*/
mPlayer.setGSVideoView(gsVideoView);
//加入直播房间
mPlayer.join(context,mInitParam,playListener);
toucherLayout.addView(gsVideoView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
imageViewClose = new ImageView(context);
imageViewClose.setImageDrawable(RePlugin.getPluginContext().getResources().getDrawable(R.drawable.course_icon_remove));
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(DimensionUtils.
dp2px(context, 16), DimensionUtils.dp2px(context, 16));
layoutParams.gravity = Gravity.TOP | Gravity.RIGHT;
layoutParams.rightMargin = DimensionUtils.dp2px(context, 3);
layoutParams.topMargin = DimensionUtils.dp2px(context, 3);
imageViewClose.setLayoutParams(layoutParams);
toucherLayout.addView(imageViewClose,layoutParams);
//添加toucherlayout
if(isInit) {
windowManager.addView(toucherLayout,params);
} else {
windowManager.updateViewLayout(toucherLayout,params);
}需要注意两点
一是 8.0以后权限定义变了 需要修改type
//设置type.系统提示型窗口，一般都在应用程序窗口之上.
if (Build.VERSION.SDK_INT >= 26) {//8.0新特性
params.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
}二是 参考系和初始坐标的概念，参考系Gravity 即以哪点为原点而不是初始化弹窗相对于屏幕的位置！
其中需要注意的是其Gravity属性:
注意:Gravity不是说你添加到WindowManager中的View相对屏幕的几种放置,而是说你可以设置你的 参 考 系 !
例如:mWinParams.gravity= Gravity.LEFT | Gravity.TOP;意思是以屏幕左上角为参考系,那么屏幕左上角的坐标就是(0,0),这是你后面摆放View位置的唯一依据.当你设置为mWinParams.gravity = Gravity.CENTER;那么你的屏幕中心为参考系,坐标(0,0).一般我们用屏幕左上角为参考系.三是 touch事件的处理,由于我们View先相应touch事件，之后才会传递到onClick点击事件，如果touch拦截了就不会传递到下一级了
１，我们通过手指移动后的位置，添加偏移量，然后windowManger 调用 updateViewlayout 更新界面 达到实时拖动更改位置
２，通过计算上一次触碰屏幕位置和这一次触碰屏幕的偏移量，ｘ轴和y轴的偏移量都小于2像素，认定为点击事件，执行整个窗体的点击事件，否则执行整个窗体的touch事件
//主动计算出当前View的宽高信息.
toucherLayout.measure(View.MeasureSpec.UNSPECIFIED,View.MeasureSpec.UNSPECIFIED);
//处理touch
toucherLayout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
isMoved = false;
// 记录按下位置
lastX = event.getRawX();
lastY = event.getRawY();
start_X = event.getRawX();
start_Y = event.getRawY();
break;
case MotionEvent.ACTION_MOVE:
isMoved = true;
// 记录移动后的位置
float moveX = event.getRawX();
float moveY = event.getRawY();
// 获取当前窗口的布局属性, 添加偏移量, 并更新界面, 实现移动
params.x += (int) (moveX - lastX);
params.y += (int) (moveY - lastY);
windowManager.updateViewLayout(toucherLayout,params);
lastX = moveX;
lastY = moveY;
break;
case MotionEvent.ACTION_UP:
offset = DimensionUtils.dp2px(context, 2);//移动偏移量
float fmoveX = event.getRawX();
float fmoveY = event.getRawY();
if (Math.abs(fmoveX-start_X)<offset && Math.abs(fmoveY-start_Y)<offset){
isMoved = false;
remove(context);
leaveCast(context);
String PARAM_CIRCLE_ID = "param_circle_id";
Intent intent = new Intent();
intent.putExtra(PARAM_CIRCLE_ID,circle_id);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setComponent(new ComponentName(RePlugin.getHostContext().getPackageName(),
"com.sina.licaishicircle.sections.circledetail.CircleActivity"));
context.startActivity(intent);
}else {
isMoved = true;
}
break;
}
// 如果是移动事件, 则消费掉; 如果不是, 则由其他处理, 比如点击
return isMoved;
}
