Question

我有一个计时器应用程序，我的应用程序应始终处于LandScape模式。我在代码中获得了主要布局的宽度和高度。在清单中，我使用过：

     <activity android:name=".MActivity"
                      android:label="@string/app_name"
                      android:screenOrientation="landscape"
android:theme="@android:style/Theme.NoTitleBar"
                android:configChanges="keyboardHidden|orientation">

活动中：

layout = (LinearLayout)findViewById(R.id.Rishikesh);
        ViewTreeObserver vto = layout.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            public void onGlobalLayout() {
                int finalHeight, finalWidth;
                finalHeight = layout.getMeasuredHeight();
                finalWidth = layout.getMeasuredWidth();
                Log.w("*************", "OnGlobalLayoutListener/ Footer height :"+layout.getHeight()+" Width :"+layout.getWidth());


            }
        });

它以横向模式提供高度和宽度。但是当我锁定手机时，它会以纵向模式显示高度和宽度。我不知道我做错了什么。我正在研究ANdroid 2.1。任何人都可以帮我解决这个问题。

Answer 1

删除“android:configChanges="keyboardHidden|orientation"

后检查

Answer 2

问题是您的应用程序不在前台，其他应用程序可能会请求允许纵向或仅纵向。

您会收到当前的全局布局 - 可能是肖像。你可能会在屏幕被锁定之前收到onPause（），当你的应用程序回到前台时你会收到onResume（） - 如果你不想在不在后台时获得布局，如果你是前台应用程序，只需使用bool来存储。

在Android中，横向模式更改为纵向
