DrawerLayout的內部視圖佈局總是返回FrameLayout

我有LinearLayout裏面的DrawerLayout根據layout_weight呈現抽屜項目和視圖。我試圖通過設置其高度爲0或以View.Visibility - GONE屬性以編程方式隱藏該視圖。DrawerLayout的內部視圖佈局總是返回FrameLayout

試過

通過設定其公開程度爲GONE它充當INVISIBLE

通過獲得其的LayoutParams並設置其高度爲0。雖然它作爲作用INVISIBLE

ParentLayout：mother.xml

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<android.support.v4.widget.DrawerLayout 
    android:id="@+id/activityMotherDrawerLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true"> 

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

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

每當我試着用來獲取layoutParam getLayoutPa rams它返回FrameLayout其中它的父視圖是LinearLayout。

使用Java：

mDashboardLayout = (LinearLayout)mDrawerInnerRootLayout.findViewById(R.id.activityMotherDrawerDashboardLayout); 
LinearLayout.LayoutParams mParams = (LinearLayout.LayoutParams) mDashboardLayout.getLayoutParams();//returns FrameLayout instead where it should return LinearLayout 

mDashboardLayout.setVisibility(View.GONE); //it acts as INVISIBILITY

誰能開導我，爲什麼它返回，而不是 的LinearLayout或者的FrameLayout爲什麼它的可見性變爲不可見，而不是走了嗎？

儘管更改視圖 - 可見性爲GONE或INVISIBLE仍然視圖始終是隱形的。它確實接受onClick事件。根據SO，我想徹底刪除這個觀點。我能夠使用以下方法實現它。

我正在通過編程方式將View添加到ParentView層次結構中，並刷新整個佈局。

View inflatedDashboardView; 
    inflatedDashboardView = mInflater.inflate(R.layout.layout_drawer_dashboard, mDrawerInnerRootLayout, false); 
    mDashboardLayout = (LinearLayout) inflatedDashboardView.findViewById(R.id.activityMotherDrawerDashboardLayout); 
    mDrawerInnerRootLayout.addView(inflatedDashboardView); 
    mDrawerInnerRootLayout.forceLayout();

仍然我不明白爲什麼內部ViewView佈局裏面的DrawerLayout總是返回FrameLayout。
