Question

我有以下布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:keepScreenOn="true"
>


<FrameLayout
    android:id="@+id/camera_preview"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<FrameLayout
    android:id="@+id/menus_layer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:visibility="gone">

</FrameLayout>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/orientation_layer"
    android:visibility="gone">

    <include layout="@layout/layer_orientation"/>

</FrameLayout>

<Button
    android:id="@+id/interruption_menu"
    android:layout_alignParentLeft="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Interruption"/>

<Button
    android:id="@+id/action_menu"
    android:layout_alignParentRight="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Action"/>

</RelativeLayout>

和layer_orientation.xml：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/check_orientation"
android:gravity="center"
android:layout_gravity="center"
android:visibility="visible"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:padding="5dp"
android:background="@android:color/holo_red_light"
>

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:src="@android:drawable/ic_menu_always_landscape_portrait"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/please_check_orientation"
    android:layout_gravity="fill" />
</LinearLayout>

保存布局的活动的方向设置为横向。使用OrientationEventListener我想显示并相应地旋转orientation_layer。类似的东西：

private final static int THRESHOLD = 45;
private final static int NORMAL = 270;
mOrientationEventListener = new OrientationEventListener(mContext, SensorManager.SENSOR_DELAY_UI) {
        @Override
        public void onOrientationChanged(int orientation) {
            if (mCallback != null) {
                if (orientation <= NORMAL + THRESHOLD && orientation >= NORMAL - THRESHOLD)
                    mCallback.hideOrientationLayer();
                else {
                    int rot = (NORMAL - orientation - THRESHOLD) / 90;
                    if (rot >= 0)
                        rot = (rot + 1) * 90;
                    else
                        rot = rot * 90;
                    mCallback.showOrientationLayer(rot);
                }
            }
        }
    };
    @Override
    public void showOrientationLayer(int rotation) {
        mOrientationLayer.setRotation(rotation);
        mOrientationLayer.setVisibility(View.VISIBLE);
    }

    @Override
    public void hideOrientationLayer() {
        mOrientationLayer.setVisibility(View.GONE);
    }

如果我将设备向右旋转，则框架布局显示正常，但如果我向左旋转，则只显示一半布局，另一半被切断。以下是一些屏幕截图：https://www.dropbox.com/sh/ypu6txrwpve27ud/Lv_9lTJybA 还有一个Android Studio测试项目：https://www.dropbox.com/sh/f5kiaw7y5ueb0zk/FASOGh54SD

经过一些测试后，我得出结论，这仅在KitKat上出现。

有没有人对可能出现的问题有所了解？提前谢谢！
