我已經RelativeLayout內DrawerLayout這是我的xml文件：誤差DrawerLayout和RelativeLayout的
activity_main.xml中
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"

<!--android:name="com.wunderlist.slidinglayersample.NavigationDrawerFragment"-->

這是我的Java代碼：

它並沒有真正面對過這個問題。我試圖改變RelativeLayout和DrawerLayout的位置，但它沒有奏效。我想這個問題可能在java文件中。有沒有人有任何想法如何解決這個問題？
它並沒有改變任何東西 – AndroidFreak
您可以調試該行並檢查什麼類型'mSlidingLayer'是什麼？ – AlexWalterbos
這就是代碼 – AndroidFreak
