Android基于腾讯云实时音视频仿微信视频通话最小化悬浮

来源：本站原创|时间：2020-01-10|栏目：Android|点击：次

最近项目中有需要语音、视频通话需求，看到这个像环信、融云等SDK都有具体Demo实现，但咋的领导对腾讯情有独钟啊，IM要用腾讯云IM，不妙的是腾讯云IM并不包含有音视频通话都要自己实现，没办法深入了解腾讯云产品后，决定自己基于腾讯云实时音视频做去语音、视频通话功能。在这里把实现过程记录下为以后用到便于查阅，另一方面也给有需要的人提供一个思路，让大家少走弯路，有可能我的实现的方法不是最好，但是这或许是一个可行的方案，大家不喜勿喷。基于腾讯云实时音视频SDK 6.5.7272版本，腾讯DEMO下载地址

一、实现效果

二、实现思路

我把实现思路拆分为了两步：1、视频通话Activity的最小化。 2、视频通话悬浮框的开启

具体思路是这样的：当用户点击左上角最小化按钮的时候，最小化视频通话Activity（这时Activity处于后台状态），于此同时开启悬浮框，新建一个新的ViewGroup将全局Constents.mVideoViewLayout中用户选中的最大View动态添加到悬浮框里面去，监听悬浮框的触摸事件，让悬浮框可以拖拽移动；自定义点击事件，如果用户点击了悬浮框，则移除悬浮框然后重新调起我们在后台的视频通话Activity。

1.Activity是如何实现最小化的？

Activity本身自带了一个moveTaskToBack(boolean nonRoot)，我们要实现最小化只需要调用moveTaskToBack(true)传入一个true值就可以了，但是这里有一个前提，就是需要设置Activity的启动模式为singleInstance模式，两步搞定。（注：activity最小化后重新从后台回到前台会回调onRestart()方法）

@Override
 public boolean moveTaskToBack(boolean nonRoot) {
  return super.moveTaskToBack(nonRoot);
 }

2.悬浮框是如何开启的？

悬浮框的实现方法最好写在Service里面，将悬浮框的开启关闭与服务Service的绑定解绑所关联起来，开启服务即相当于开启我们的悬浮框，解绑服务则相当于关闭关闭的悬浮框，以此来达到更好的控制效果。

a. 首先我们声明一个服务类，取名为FloatVideoWindowService：

public class FloatVideoWindowService extends Service {
 
 @Nullable
 @Override
 public IBinder onBind(Intent intent) {
  return new MyBinder();
 }
 
 public class MyBinder extends Binder {
  public FloatVideoWindowService getService() {
   return FloatVideoWindowService.this;
  }
 }
 
 @Override
 public void onCreate() {
  super.onCreate();
 }
 
 @Override
 public int onStartCommand(Intent intent, int flags, int startId) {
  return super.onStartCommand(intent, flags, startId);
 }
 
 @Override
 public void onDestroy() {
  super.onDestroy();
 }
}

b. 为悬浮框建立一个布局文件float_video_window_layout，悬浮框大小我这里固定为长80dp，高120dp，id为small_size_preview的RelativeLayout主要是一个容器，可以动态的添加view到里面去

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/small_size_frame_layout"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:background="@color/colorComBg"
 android:orientation="vertical">
 
 <com.tencent.rtmp.ui.TXCloudVideoView
  android:id="@+id/float_videoview"
  android:layout_width="80dp"
  android:layout_height="120dp"
  android:descendantFocusability="blocksDescendants"
  android:orientation="vertical" />
 
</LinearLayout>

c. 布局定义好后，接下来就要对悬浮框做一些初始化操作了，初始化操作这里我们放在服务的onCreate()生命周期里面执行，因为只需要执行一次就行了。这里的初始化主要包括对：悬浮框的基本参数（位置，宽高等），悬浮框的点击事件以及悬浮框的触摸事件（即可拖动范围）等的设置，在onBind()中从Intent中取出了Activity中用户选中最大View的id，以便在后面从 Constents.mVideoViewLayout中取出对应View，然后加入悬浮窗布局中

/**
 * 视频悬浮窗服务
 */
public class FloatVideoWindowService extends Service {
 private WindowManager mWindowManager;
 private WindowManager.LayoutParams wmParams;
 private LayoutInflater inflater;
 private String currentBigUserId;
 //浮动布局view
 private View mFloatingLayout;
 //容器父布局
 private RelativeLayout smallSizePreviewLayout;
 private TXCloudVideoView mLocalVideoView;
 
 
 @Override
 public void onCreate() {
  super.onCreate();
  initWindow();//设置悬浮窗基本参数（位置、宽高等）
  
 }
 
 @Nullable
 @Override
 public IBinder onBind(Intent intent) {
  currentBigUserId = intent.getStringExtra("userId");
  initFloating();//悬浮框点击事件的处理
  return new MyBinder();
 }
 
 public class MyBinder extends Binder {
  public FloatVideoWindowService getService() {
   return FloatVideoWindowService.this;
  }
 }
 
 
 @Override
 public int onStartCommand(Intent intent, int flags, int startId) {
  return super.onStartCommand(intent, flags, startId);
 }
 
 
 /**
  * 设置悬浮框基本参数（位置、宽高等）
  */
 private void initWindow() {
  mWindowManager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
  //设置好悬浮窗的参数
  wmParams = getParams();
  // 悬浮窗默认显示以左上角为起始坐标
  wmParams.gravity = Gravity.LEFT | Gravity.TOP;
  //悬浮窗的开始位置，因为设置的是从左上角开始，所以屏幕左上角是x=0;y=0
  wmParams.x = 70;
  wmParams.y = 210;
  //得到容器，通过这个inflater来获得悬浮窗控件
  inflater = LayoutInflater.from(getApplicationContext());
  // 获取浮动窗口视图所在布局
  mFloatingLayout = inflater.inflate(R.layout.alert_float_video_layout, null);
  // 添加悬浮窗的视图
  mWindowManager.addView(mFloatingLayout, wmParams);
 }
 
 
 private WindowManager.LayoutParams getParams() {
  wmParams = new WindowManager.LayoutParams();
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
   wmParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
  } else {
   wmParams.type = WindowManager.LayoutParams.TYPE_PHONE;
  }
  //设置可以显示在状态栏上
  wmParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR |
    WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH;
 
  //设置悬浮窗口长宽数据
  wmParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
  wmParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
  return wmParams;
 }
 
 private void initFloating() {
  
 
 }
}

d. 在悬浮框成功被初始化以及相关参数被设置后，接下来就需要将Activity中用户选中最大的View添加到悬浮框里面去了，这样我们才能看到视频画面嘛，同样我们是在Service的onCreate这个生命周期中initFloating()完成这个操作的，代码如下所示：

TRTCVideoViewLayout mTRTCVideoViewLayout = Constents.mVideoViewLayout;
TXCloudVideoView mLocalVideoView = mTRTCVideoViewLayout.getCloudVideoViewByUseId(currentBigUserId);
if (mLocalVideoView == null) {
 mLocalVideoView = mTRTCVideoViewLayout.getCloudVideoViewByIndex(0);
}
if (ConstData.userid.equals(currentBigUserId)) {
  TXCGLSurfaceView mTXCGLSurfaceView = mLocalVideoView.getGLSurfaceView();
  if (mTXCGLSurfaceView != null && mTXCGLSurfaceView.getParent() != null) {
   ((ViewGroup) mTXCGLSurfaceView.getParent()).removeView(mTXCGLSurfaceView);
   mTXCloudVideoView.addVideoView(mTXCGLSurfaceView);
  }
} else {
  TextureView mTextureView = mLocalVideoView.getVideoView();
  if (mTextureView != null && mTextureView.getParent() != null) {
   ((ViewGroup) mTextureView.getParent()).removeView(mTextureView);
    mTXCloudVideoView.addVideoView(mTextureView);
  }
}

e. 我们上面说到要将服务Service的绑定与解绑与悬浮框的开启和关闭相结合，所以既然我们在服务的onCreate()方法中开启了悬浮框，那么就应该在其onDestroy()方法中对悬浮框进行关闭，关闭悬浮框的本质是将相关View给移除掉，在服务的onDestroy()方法中执行如下代码：

@Override
 public void onDestroy() {
  super.onDestroy();
  if (mFloatingLayout != null) {
   // 移除悬浮窗口
   mWindowManager.removeView(mFloatingLayout);
   mFloatingLayout = null;
   Constents.isShowFloatWindow = false;
  }
 }

f. 服务的绑定方式有bindService和startService两种，使用不同的绑定方式其生命周期也会不一样，已知我们需要让悬浮框在视频通话activity finish掉的时候也顺便关掉，那么理所当然我们就应该采用bind方式来启动服务，让他的生命周期跟随他的开启者，也即是跟随开启它的activity生命周期。

intent = new Intent(this, FloatVideoWindowService.class);//开启服务显示悬浮框
bindService(intent, mVideoServiceConnection, Context.BIND_AUTO_CREATE);
 
ServiceConnection mVideoServiceConnection = new ServiceConnection() {
 
  @Override
  public void onServiceConnected(ComponentName name, IBinder service) {
   // 获取服务的操作对象
   FloatVideoWindowService.MyBinder binder = (FloatVideoWindowService.MyBinder) service;
   binder.getService();
  }
 
  @Override
  public void onServiceDisconnected(ComponentName name) {
  }
 };

Service完整代码如下：

/**

public class FloatVideoWindowService extends Service {
 private WindowManager mWindowManager;
 private WindowManager.LayoutParams wmParams;

     isMove = false;
     mTouchStartX = (int) event.getRawX();
     mTouchStartY = (int) event.getRawY();
     mStartX = (int) event.getX();
     mStartY = (int) event.getY();
     break;
    case MotionEvent.ACTION_MOVE:
     mTouchCurrentX = (int) event.getRawX();
     mTouchCurrentY = (int) event.getRawY();
     wmParams.x += mTouchCurrentX - mTouchStartX;

    default:
     break;
   }
   //如果是移动事件不触发OnClick事件，防止移动的时候一放手形成点击事件
   return isMove;
  }
 }
 
}

Activity中的操作

现在我们将思路了捋一下，假设现在我正在进行视频通话，点击视频最小化按钮，我们应该按顺序执行如下步骤：应该是会出现个悬浮框。我们用mServiceBound保存Service注册状态，后面解绑时候用这个去判断，不能有些从其他页面过来调用OnRestart()方法的会报错说 Service not register之类的错误。

/*
 * 开启悬浮Video服务
 */
private void startVideoService() {
 //最小化Activity
 moveTaskToBack(true);
 Constents.mVideoViewLayout = mVideoViewLayout;
 //开启服务显示悬浮框
 Intent floatVideoIntent = new Intent(this, FloatVideoWindowService.class);
 floatVideoIntent.putExtra("userId", currentBigUserId);
 mServiceBound=bindService(floatVideoIntent, mVideoCallServiceConnection, Context.BIND_AUTO_CREATE);
}

注意：这里用了一个全部变量 Constents.mVideoViewLayout 保存Activity中的mVideoViewLayout，以便在上面的Service中使用。

当我们点击悬浮框的时候，可以使用startActivity(intent)来再次打开我们的activity，这时候视频通话activity会回调onRestart()方法，我们在onRestart()生命周期里面unbind解绑掉悬浮框服务，并且重新设置mVideoViewLayout展示

@Override
 protected void onRestart() {
  super.onRestart();
  //不显示悬浮框
  if (mServiceBound) {
   unbindService(mVideoCallServiceConnection);
   mServiceBound = false;
  }
  TXCloudVideoView txCloudVideoView = mVideoViewLayout.getCloudVideoViewByUseId(currentBigUserId);
  if (txCloudVideoView == null) {
   txCloudVideoView = mVideoViewLayout.getCloudVideoViewByIndex(0);
  }
  if(ConstData.userid.equals(currentBigUserId)){
   TXCGLSurfaceView mTXCGLSurfaceView=txCloudVideoView.getGLSurfaceView();
   if (mTXCGLSurfaceView!=null && mTXCGLSurfaceView.getParent() != null) {
    ((ViewGroup) mTXCGLSurfaceView.getParent()).removeView(mTXCGLSurfaceView);
    txCloudVideoView.addVideoView(mTXCGLSurfaceView);
   }
  }else{
   TextureView mTextureView=txCloudVideoView.getVideoView();
   if (mTextureView!=null && mTextureView.getParent() != null) {
    ((ViewGroup) mTextureView.getParent()).removeView(mTextureView);
    txCloudVideoView.addVideoView(mTextureView);
   }
  }
 }

有评论区小伙伴要求晒出Constents.java，这里我也把这个类分享出来，Constents类主要是定义一些全局变量

Constents完整源码如下：

public class Constents {
 
 /**
  * 1对1语音通话
  */
 public final static String ONE_TO_ONE_AUDIO_CALL = "1";
 /**
  * 1对多语音通话
  */
 public final static String ONE_TO_MULTIPE_AUDIO_CALL = "2";
 /**
  * 1对1视频通话
  */
 public final static String ONE_TO_ONE_VIDEO_CALL = "3";
 
 /**
  * 1对多视频通话
  */
 public final static String ONE_TO_MULTIPE_VIDEO_CALL = "4";
 
 /**
  * 实时语音通话消息描述内容
  */
 public final static String AUDIO_CALL_MESSAGE_DESC = "AUDIO_CALL_MESSAGE_DESC";
 /**
  * 实时视频通话消息描述内容
  */
 public final static String VIDEO_CALL_MESSAGE_DESC = "VIDEO_CALL_MESSAGE_DESC";
 
 /**
  * 实时语音通话消息拒接
  */
 public final static String AUDIO_CALL_MESSAGE_DECLINE_DESC = "AUDIO_CALL_MESSAGE_DECLINE_DESC";
 /**
  * 实时视频通话消息拒接
  */
 public final static String VIDEO_CALL_MESSAGE_DECLINE_DESC = "VIDEO_CALL_MESSAGE_DECLINE_DESC";
 
 /**
  * 悬浮窗与TRTCVideoActivity共享的视频View
  */
 public static TRTCVideoViewLayout mVideoViewLayout;
 
 /**
  * 悬浮窗是否开启
  */
 public static boolean isShowFloatWindow = false;
 
 /**
  * 语音通话开始计时时间（悬浮窗要显示时间在这里记录开始值）
  */
 public static long audioCallStartTime;

}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
