DrawerLayout內部片段提供Measure.EXACTLY錯誤

Question

根據這個相關的問題Make drawerlayout inside fragment full screen height 我不確定是否正確或錯誤，但它似乎像片段總是不是全屏，即它只複製它的內容的佈局屬性和使用它這就是爲什麼你可以在一個佈局中有兩個或更多的片段。

現在我有問題將Drawerlayout的高度設置爲match_parent，下面粘貼了我得到的錯誤的完整堆棧。我試過每一種方法，我知道強迫佈局參數，但它只是不工作，如果我給佈局一個特定的dp像500dp它將然後工作。

Answer 1

我決定通過擴展DrawerLayout自己創建一個自定義DrawerLayout，什麼也沒做多，但重複的DrawerLayout方法。但我唯一做的是在覆蓋onMeasure方法在DrawerLayout。

下面是我的自定義DrawerLayout，我怎麼在我的佈局::稱之爲

public class WhalesDrawerLayout extends DrawerLayout { 

    public WhalesDrawerLayout(Context context) { 
     super(context); 
    } 

    public WhalesDrawerLayout(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public WhalesDrawerLayout(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     widthMeasureSpec = MeasureSpec.makeMeasureSpec(
       MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY); 
     heightMeasureSpec = MeasureSpec.makeMeasureSpec(
       MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY); 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    } 
} 

而在你的佈局應該叫這樣的：

<whalescorp.projectname.packagename.WhalesDrawerLayout 
    android:id="@+id/drawer" 
    android:fitsSystemWindows="true" 
    tools:openDrawer="start" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent"> 

</whalescorp.projectname.packagename.WhalesDrawerLayout> 

通過鍵入類名的activity.xml，它會帶來建議，你也可以很容易地得到它，同時你需要在它的工作之前重建你的項目，你可以在你的代碼中這樣調用它::

final WhalesDrawerLayout drawerLayout = l.findViewById(R.id.drawer); 

Answer 2

這也可能是由於新的ConstraintLayout而發生的。確保抽屜佈局不在ConstraintLayout的層次結構中。

這是Android上的一個非常愚蠢的錯誤。我會盡力爲它提交一個錯誤。
