应用程序崩溃异常,这是我在Crashlytics上找到的跟踪日志:

如何为所有活动设置Orientation Fixed

我想锁定我的应用程序的屏幕方向.我的意思是所有活动必须具有相同的landscape方向.我不想android:screenOrientation="portrait"为所有活动添加 清单.还有其他方法吗？感谢和问候

我正在努力完成Reto Meier的推荐方法,以防止屏幕方向发生变化.可以在Android Protips:下载幻灯片和代码片段的位置找到他在Google IO期间的演讲中的幻灯片(参见#23).

我已逐步完成代码并设置了值,但屏幕方向仍然有所改变.仅供参考,我在应用程序中注册了这个监听器.

这是我的代码:

final SensorManager sm = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    sm.registerListener(
        new SensorEventListener() {
            @Override
            public void onSensorChanged(SensorEvent sensorEvent) {
                if (sensorEvent.sensor.getType() == Sensor.TYPE_ORIENTATION) {
                    final WindowManager wm = (WindowManager) getApplicationContext()
                            .getSystemService(Context.WINDOW_SERVICE);
                    final Display display = wm.getDefaultDisplay();

                    int x = SensorManager.AXIS_X;
                    int y = SensorManager.AXIS_Y;

                    switch (display.getRotation()) {
                    case Surface.ROTATION_90:
                        x = SensorManager.AXIS_Y;
                        y = SensorManager.AXIS_MINUS_X;

                        break;
                    case Surface.ROTATION_180:
                        y = SensorManager.AXIS_MINUS_Y;

                        break;
                    case Surface.ROTATION_270:
                        x = SensorManager.AXIS_MINUS_Y;
                        y = SensorManager.AXIS_MINUS_X;

                        break;
                    case Surface.ROTATION_0:
                    default:
                        break; …
