  4 | 类似微信视频、语音时点击返回会形成一个App小窗口浮动在界面上，点击继续是通通话，如下图：

 10 | > 技术分析 
 11 | 
 12 | 其实实现这个功能只需要你细心分析一下就有思路了：首先这个小窗口是浮动在app最上层的视图，其次所有触屏事件需先由该小窗口处理，还有就是小窗口的生命周期和Application也能虽可能不能同生，但是确是可以共死。所以可以在Application中创建一个view添加到WindowManage，这里将视图为view的window的type设置成系统级别的窗口，这样这个window可以在在全局呈现。另外，还需要让这个window可以随手指拖动而滑动，手指释放后会回弹到距离这个释放点最近的屏幕侧边，所以需要重写view 的OnTouch事件。
 13 | 
 14 | > 代码细节实现
 15 | 
 16 |  -  创建全局Application，在Application创建的时候初始化一个view，以及一个WindowManager.LayoutParams,并设置get方法，方便外部调用:
 17 |  
 18 | 
 19 | ```
 20 | private SmallWindowView windowView;
 21 |     private WindowManager wm;
 22 |     private WindowManager.LayoutParams mLayoutParams;
 23 |     public SmallWindowView getWindowView() {
 24 |         return windowView;
 25 |     }
 26 |     public WindowManager getWm() {
 27 |         return wm;
 28 |     }
 29 |     public WindowManager.LayoutParams getmLayoutParams() {
 30 |         return mLayoutParams;
 31 |     }
 32 |     @Override
 33 |     public void onCreate() {
 34 |         super.onCreate();
 35 |         initSmallViewLayout();
 36 |     }
 37 |     public void initSmallViewLayout() {
 38 |         windowView = (SmallWindowView) LayoutInflater.from(this).inflate(R.layout.small_window, null);
 39 |         wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
 40 |         mLayoutParams = new WindowManager.LayoutParams(
 41 |                 ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT,
 42 |                 WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
 43 |                 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
 44 |                         | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
 45 |                 PixelFormat.TRANSLUCENT);
 46 |         mLayoutParams.gravity = Gravity.NO_GRAVITY;
 47 |         //使用非CENTER时，可以通过设置XY的值来改变View的位置
 48 |         windowView.setWm(wm);
 49 |         windowView.setWmParams(mLayoutParams);
 50 |     }
 51 | ```
 52 | -  编写一个BaseActivity 实现可供子类来显示隐藏窗口的方法：
 53 | 
 54 | ```
 55 |   private WindowManager wm;
 56 |     private SmallWindowView windowView;
 57 |     private WindowManager.LayoutParams mLayoutParams;
 58 |     private int OVERLAY_PERMISSION_REQ_CODE = 2;
 59 |     private boolean isRange = false;
 60 | 
 61 |     @Override
 62 |     protected void onCreate(Bundle savedInstanceState) {
 63 |         super.onCreate(savedInstanceState);
 64 |         wm = ((MyApplication)getApplication()).getWm();
 65 |         windowView = ((MyApplication)getApplication()).getWindowView();
 66 |         mLayoutParams = ((MyApplication)getApplication()).getmLayoutParams();
 67 |     }
 68 | 
 69 | 
 70 |     public void alertWindow() {
 71 |         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { // 7.0 以上需要引导用去设置开启窗口浮动权限
 72 |             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { // 8.0 以上type需要设置成这个
 73 |                 mLayoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
 74 |             }
 75 |             requestDrawOverLays();
 76 |         } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // 6.0 动态申请
 77 |             ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SYSTEM_ALERT_WINDOW}, 1);
 78 |         }
 79 |     }
 80 | 
 81 |     @Override
 82 |     public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
 83 |         super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 84 |         if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
 85 |             if (wm != null && windowView.getWm() == null) {
 86 |                 wm.addView(windowView, mLayoutParams);
 87 |             }
 88 |         } else {
 89 |             Toast.makeText(this, "权限申请失败", Toast.LENGTH_SHORT).show();
 90 |         }
 91 |     }
 92 | 
 93 | 
 94 |     private int[] location = new int[2]; // 小窗口位置坐标
 95 | 
 96 |     @Override
 97 |     public boolean onTouchEvent(MotionEvent event) {
 98 |         if (event.getAction() == MotionEvent.ACTION_DOWN) {
 99 |             isRange = calcPointRange(event);
100 |         }
101 |         if (isRange) {

290 | ```
291 | 以上就能实现一个应用内小窗口了，这里windowManager的布局参数有坑要踩：
292 | 
293 |  - 不设置Gravity属性，window的坐标是以屏幕左上角为(0,0)原点，而当第一次接受到触摸事件之后就会以默认原点更改为屏幕中心，[Github源码，给个小星星](https://github.com/luweicheng24/SmallWindow)
