Android实现监听屏幕旋转

需求是屏幕每旋转到一定角度时，通过做一些操作，比如给webview发送消息
具体实现：
onCreate 方法里
//屏幕方向监听        OrientationEventListener mOrientationListener = new OrientationEventListener(this,                SensorManager.SENSOR_DELAY_NORMAL) {            @Override            public void onOrientationChanged(int orientation) {                // Log.v(DEBUG_TAG,"Orientation changed to " + orientation);                if (orientation > 350 || orientation < 10) { //0度                    orientation = 0;                    Point outSize = new Point();                    getWindowManager().getDefaultDisplay().getRealSize(outSize);                    int x = outSize.x;                    int y = outSize.y;                    System.out.println("x = " + x + ",y = " + y);                    System.out.println("xxxxxxxxx:竖屏 ");                    try {                        JSONObject obj = new JSONObject();                        obj.put("width", x);                        obj.put("height", y);                        obj.put("orientation", "portrait");                        JavascriptWXBridge.SrcChange(obj);                    } catch (JSONException e) {                        e.printStackTrace();                    }                } else if (orientation > 80 && orientation < 100) { //90度                    orientation = 90;                    Point outSize = new Point();                    getWindowManager().getDefaultDisplay().getRealSize(outSize);                    int x = outSize.x;                    int y = outSize.y;                    System.out.println("x = " + x + ",y = " + y);                    System.out.println("xxxxxxxxx:向右横屏 ");                    try {                        JSONObject obj = new JSONObject();                        obj.put("width", x);                        obj.put("height", y);                        obj.put("orientation", "landscape");                        JavascriptWXBridge.SrcChange(obj);                    } catch (JSONException e) {                        e.printStackTrace();                    }                } else if (orientation > 170 && orientation < 190) { //180度                    orientation = 180;                    Point outSize = new Point();                    getWindowManager().getDefaultDisplay().getRealSize(outSize);                    int x = outSize.x;                    int y = outSize.y;                    System.out.println("x = " + x + ",y = " + y);                    System.out.println("xxxxxxxxx:竖屏 ");                    try {                        JSONObject obj = new JSONObject();                        obj.put("width", x);                        obj.put("height", y);                        obj.put("orientation", "portrait");                        JavascriptWXBridge.SrcChange(obj);                    } catch (JSONException e) {                        e.printStackTrace();                    }                } else if (orientation > 260 && orientation < 280) { //270度                    orientation = 270;                    Point outSize = new Point();                    getWindowManager().getDefaultDisplay().getRealSize(outSize);                    int x = outSize.x;                    int y = outSize.y;                    System.out.println("x = " + x + ",y = " + y);                    System.out.println("xxxxxxxxx:向左横屏 ");                    try {                        JSONObject obj = new JSONObject();                        obj.put("width", x);                        obj.put("height", y);                        obj.put("orientation", "landscape");                        JavascriptWXBridge.SrcChange(obj);                    } catch (JSONException e) {                        e.printStackTrace();                    }                } else {                    return;                }            }        };
