Android仿微信视屏悬浮窗效果
在项目中需要对接入的腾讯云音视频,可以悬浮窗显示,悬浮窗可拖拽,并且在悬浮窗不影响其他的activity的焦点。
这个大神的文章Android基于腾讯云实时音视频仿微信视频通话最小化悬浮,他讲的是视频通话时,将远端视频以悬浮窗形式展示,根据他的代码我进行了部分简化
1.悬浮窗效果:点击缩小按钮,将当前远端视屏加载进悬浮窗,且悬浮窗可拖拽,不影响其他界面焦点;点击悬浮窗可返回原来的Activity
2.实现悬浮窗需要:
在androidManifest中申请悬浮窗权限<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
在androidManifest中注册FloatWindowService
3.视屏activity实现:
-将activity置于后台关键代码:moveTaskToBack(true);//将activity置于后台
-开启悬浮窗
/** * 定义服务绑定的回调 开启视频通话服务连接 */ private ServiceConnection mVideoCallServiceConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { // 获取服务的操作对象 FloatWindowService.MyBinder binder = (FloatWindowService.MyBinder) service; binder.getService(); } @Override public void onServiceDisconnected(ComponentName name) { } }; /* * 开启悬浮Video服务 */ private void startVideoService() { //最小化Activity moveTaskToBack(true);//将activity置于后台 //开启服务显示悬浮框 Intent serviceVideoIntent = new Intent(this, FloatWindowService.class); mServiceBound = bindService(serviceVideoIntent, mVideoCallServiceConnection, Context.BIND_AUTO_CREATE);//绑定Service }
-悬浮窗结束时
//在onDestroy()与onReStart()中解绑并销毁相关内容 if (mServiceBound) { unbindService(mVideoCallServiceConnection);//解绑 mServiceBound = false; }
4.悬浮窗实现相关代码:
/** * 视频悬浮窗服务 */ public class FloatWindowService extends Service implements View.OnTouchListener { private WindowManager mWindowManager; private WindowManager.LayoutParams wmParams; private LayoutInflater inflater; //浮动布局view private View mFloatingLayout; //容器父布局 private View mMainVIew; //开始触控的坐标,移动时的坐标(相对于屏幕左上角的坐标) private int mTouchStartX, mTouchStartY, mTouchCurrentX, mTouchCurrentY; //开始时的坐标和结束时的坐标(相对于自身控件的坐标) private int mStartX, mStartY, mStopX, mStopY; //判断悬浮窗口是否移动,这里做个标记,防止移动后松手触发了点击事件 private boolean isMove; @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("localUserId"); remoteUserId = intent.getStringExtra("remoteUserId"); initFloating();//悬浮框点击事件的处理 return new MyBinder(); } public class MyBinder extends Binder { public FloatWindowService getService() { return FloatWindowService.this; } } @Override public int onStartCommand(Intent intent, int flags, int startId) { return super.onStartCommand(intent, flags, startId); } @Override public void onDestroy() { super.onDestroy(); if (mFloatingLayout != null) { // 移除悬浮窗口 mWindowManager.removeView(mFloatingLayout); mFloatingLayout = null; } } /** * 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.RIGHT | Gravity.TOP; //悬浮窗的开始位置,因为设置的是从右上角开始,所以屏幕左上角是x=屏幕最大值;y=0 wmParams.x = 10; wmParams.y = 120; //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.dlg_floatview, 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; } //加载远端视屏:在这对悬浮窗内内容做操作 private void initFloating() { //将子View加载进悬浮窗View mMainView = mFloatingLayout.findViewById(R.id.trtc_video_view_layout_float);//悬浮窗父布局 View mChildView = renderView.getChildView();//加载进悬浮窗的子View,这个VIew来自天转过来的那个Activity里面的那个需要加载的View mMainView.addView(mChildView);//将需要悬浮显示的Viewadd到mTXCloudVideoView中 //悬浮框触摸事件,设置悬浮框可拖动 mTXCloudVideoView.setOnTouchListener(this::onTouch); //悬浮框点击事件 mTXCloudVideoView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //在这里实现点击重新回到Activity Intent intent = new Intent(FloatWindowService.this, RtcActivity.class);//从该service跳转至该activity会将该activity从后台唤醒,所以activity会走onReStart() intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//从Service跳转至RTCActivity,需要Intent.FLAG_ACTIVITY_NEW_TASK,不然会崩溃 startActivity(intent); } }); } //触摸事件 @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); switch (action) { case MotionEvent.ACTION_DOWN: 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 += mTouchStartX - mTouchCurrentX; wmParams.y += mTouchCurrentY - mTouchStartY; ALog.dTag("FloatingListener() onTouch",mTouchCurrentX,mTouchStartX,mTouchCurrentY,mTouchStartY); mWindowManager.updateViewLayout(mFloatingLayout, wmParams); mTouchStartX = mTouchCurrentX; mTouchStartY = mTouchCurrentY; break; case MotionEvent.ACTION_UP: mStopX = (int) event.getX(); mStopY = (int) event.getY(); if (Math.abs(mStartX - mStopX) >= 1 || Math.abs(mStartY - mStopY) >= 1) { isMove = true; } break; 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; } }
ps:使用Service做悬浮窗的载体是为了,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悬浮框,以此来达到更好的控制效果。
