Android 中的橫向模式更改為縱向

Question

我有一個計時器應用程序，我的應用程序應該始終處於 LandScape 模式。 我在代碼中獲取我的主要布局的寬度和高度。 在清單中，我使用過：

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

在活動中：

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());


            }
        });

它在橫向模式下提供高度和寬度。 但是當我鎖定手機時，它會在縱向模式下給出高度和寬度。 我做錯了什么我不知道。 我正在研究 ANdroid 2.1。 誰能幫我解決這個問題。

Answer 1

刪除“ android:configChanges="keyboardHidden|orientation"后檢查

Answer 2

問題是您的應用程序不在前台，其他應用程序可能會請求允許縱向或僅縱向。

您會收到當前的全局布局 - 可能是縱向的。 可能您在屏幕鎖定之前收到 onPause() ，當您的應用程序返回前台時收到 onResume() - 如果您不想在不在后台時獲取布局，如果您是前台應用程序，只需使用 bool 進行存儲。
