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 {

                    }
                } else if (orientation > 260 && orientation < 280) { //270度
                    orientation = 270;
                    Point outSize = new Point();
                    getWindowManager().getDefaultDisplay().getRealSize(outSize);
                    int x = outSize.x;

                    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);
