之前接了需求要让视频播放时可以像优酷视频那样在悬浮窗里播放,并且悬浮窗和主播放页面之间要实现无缝切换,项目中使用的是自封装的ijkplayer
这个要求就代表不能在悬浮窗中新建视频控件,所以需要在悬浮窗中复用主页面的视频控件,以达到无缝衔接的效果。

主页面对应的视频控件的父view

<FrameLayout
      android:id="@+id/vw_live"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_centerInParent="true"/>

用FrameLayout作为添加视频控件的ParentView,通过addview方法将新建的播放器控件添加到父控件内部

vw_live = new IjkVideoView(this);
video_frame = findViewById(R.id.vw_live);
video_frame.addView(vw_live);

主播放界面的启动模式

播放主界面的activity的启动模式不能为默认,因为我们要保证播放主界面在显示悬浮窗的时候退到后台,但是整个的应用不能退到后台,所以activity的启动模式改为singleInstance

android:launchMode="singleInstance"

退到后台我们通过moveTaskToBack(true)方法;

moveTaskToBack(true);

可以让播放界面退到后台而整个应用不会退回后台

权限请求

要使用悬浮窗需要申请权限

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
if (!Settings.canDrawOverlays(this)) {
      Toast.makeText(this, "当前无权限,请授权", Toast.LENGTH_SHORT);
      startActivityForResult(new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName())), 2);
    } 

悬浮窗

 @SuppressLint("ClickableViewAccessibility")
  public void showFloatingWindowView(IjkVideoView view) {
    // 悬浮窗显示视图
    LayoutInflater layoutInflater = LayoutInflater.from(activity);
    mShowView = layoutInflater.inflate(R.layout.video_floating_window_layout, null);;
    // 获取系统窗口管理服务
    mWindowManager = (WindowManager) activity.getSystemService(Context.WINDOW_SERVICE);
    // 悬浮窗口参数设置及返回
    mFloatParams = getParams();
    //floatingWindow内部控件实例
    init(view);
    // 设置窗口触摸移动事件
    mShowView.setOnTouchListener(new FloatViewMoveListener());

    // 悬浮窗生成
    mWindowManager.addView(mShowView, mFloatParams);
  }
  private void init(IjkVideoView viewGroup){
    videoLayout = mShowView.findViewById(R.id.floating_video);
    videoLayout.removeAllViews();
    if (viewGroup != null){
      ijkVideoView = viewGroup;
      videoLayout.addView(ijkVideoView,new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT
          ,ViewGroup.LayoutParams.MATCH_PARENT));
    }

    mBtnCloseFloatingWindow = mShowView.findViewById(R.id.close_floating_view);
    mBtnCloseFloatingWindow.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {

      }
    });
    mBtnBackFloatingWindow = (ImageView)mShowView.findViewById(R.id.back_floating_view);
    mBtnBackFloatingWindow.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {

      }
    });
  }

  private WindowManager.LayoutParams getParams() {
    WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
    //设置悬浮窗口类型
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
      layoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
    } else {
      layoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
    }
    //设置悬浮窗口属性
    layoutParams.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;
    //设置悬浮窗口透明
    layoutParams.format = PixelFormat.TRANSLUCENT;
    //设置悬浮窗口长宽数据
    layoutParams.width = 500;
    layoutParams.height = 340;
    //设置悬浮窗显示位置
    layoutParams.gravity = Gravity.START | Gravity.TOP;
    layoutParams.x = 100;
    layoutParams.y = 100;
    return layoutParams;
  }

悬浮窗的xml,可通过自定义获得自己想要的效果

<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/floating_video_layout"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
  <FrameLayout
    android:id="@+id/floating_video"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>


  <ImageView
    android:id="@+id/close_floating_view"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:layout_gravity="end"
    android:padding="10dp"
    android:src="@android:drawable/ic_menu_close_clear_cancel" />

  <ImageView
    android:id="@+id/back_floating_view"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:padding="10dp"
    android:src="@android:drawable/ic_menu_revert" />
</FrameLayout>

悬浮窗的滑动,我们可以通过自定义点击监听实现

/**
   * 浮窗移动/点击监听
   */
  private class FloatViewMoveListener implements View.OnTouchListener {

    //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;
    private int mTouchStartY;
    //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;
    //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 boolean onTouch(View view, MotionEvent motionEvent) {
      int action = motionEvent.getAction();
      int x = (int) motionEvent.getX();
      int y = (int) motionEvent.getY();
      switch (action) {
        case MotionEvent.ACTION_DOWN:
          isMove = false;
          mTouchStartX = (int) motionEvent.getRawX();
          mTouchStartY = (int) motionEvent.getRawY();
          mStartX = x;
          mStartY = y;
          break;
        case MotionEvent.ACTION_MOVE:
          int mTouchCurrentX = (int) motionEvent.getRawX();
          int mTouchCurrentY = (int) motionEvent.getRawY();
          mFloatParams.x += mTouchCurrentX - mTouchStartX;
          mFloatParams.y += mTouchCurrentY - mTouchStartY;
          mWindowManager.updateViewLayout(mShowView, mFloatParams);
          mTouchStartX = mTouchCurrentX;
          mTouchStartY = mTouchCurrentY;
          float deltaX = x - mStartX;
          float deltaY = y - mStartY;
          if (Math.abs(deltaX) >= 5 || Math.abs(deltaY) >= 5) {
            isMove = true;
          }
          break;
        case MotionEvent.ACTION_UP:
          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;
    }
  }

悬浮窗的消失,在这里调用videoLayout.removeAllViews()是为了将复用的视频控件的父View清空,返回主播放activity的时候调用addview方法不会再报 child view has Parent,you have to call removeView()的错

public void dismiss() {
    if (mWindowManager != null && mShowView != null) {
      videoLayout.removeAllViews();
      if (mShowView.getParent() != null){
        mWindowManager.removeView(mShowView);
      }
    }
  }

启动悬浮窗

 public videoFloatingWindow(Context context){
    super(context);
    this.activity = context;
  }

对于悬浮窗的调用

用hasBind来记录是否调用了悬浮窗

 private void startFloatingWindow(){
    if (!Settings.canDrawOverlays(this)) {
      Toast.makeText(this, "当前无权限,请授权", Toast.LENGTH_SHORT);
      startActivityForResult(new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName())), 2);
    } else {
      video_frame.removeView(vw_live);
      videoFloatingWindow.getInstance(this).showFloatingWindowView(vw_live);
      hasBind = true;
      moveTaskToBack(true);
    }
  }

注意

一.由于主界面activity使用了singleInstance启动模式,所以从悬浮窗返回主界面activity时,要添加flag

  Intent intent = new Intent(activity, activity.getClass());
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        activity.startActivity(intent);

二.当主界面的activity退回后台,再重新进入主界面的时候,注意,不再调用onCreate方法,而是调用onNewIntent,所以重写onNewIntent方法,重新进入主界面,悬浮窗消失

 @Override
  protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    Log.d("RemoteView", "重新显示了");
    //不显示悬浮框
    if (hasBind){
      videoFloatingWindow.getInstance(this).dismiss();
      video_frame.removeAllViews();
      if (vw_live != null){
        video_frame.addView(vw_live);
      }
      hasBind = false;
    }
  }
