ADT 布局编辑器中的导航抽屉呈现错误

Question

<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#111"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp" />

根据Create a Navigation Drawer 文档将其添加到布局 xml 会产生

Exception raised during rendering: DrawerLayout must be measured with MeasureSpec.EXACTLY.
Exception details are logged in Window > Show View > Error Log

java.lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY.

Answer 1

我也有类似的问题。 如果您想暂时预览布局，可以暂时将宽度和高度更改为绝对。

例如：-

<android.support.v4.widget.DrawerLayout

    xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="400px"

    android:layout_height="800px">

Answer 2

此问题已在 7 月发布的支持库版本 18 中得到修复。

在 Eclipse 中右键单击您的项目 > 选择 android 工具 > 添加支持库。

已修复。 :)

Answer 3

从另一个 Question 我通过扩展 DrawerLayout 并强制使用正确的 Measure_Specs 解决了这个问题：

public class CustomDrawerLayout extends DrawerLayout {

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

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

    public CustomDrawerLayout(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);
    }

}

Answer 4

Asmok 的回答很好，但我是这种人，总是忘记撤销这种“临时”编辑。 （也就是说临时的可能会变得很大^^）

所以我改为使用<include> 标记并将布局拆分为两个文件。

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- The main content view -->
    <include layout="@layout/main_layout" />

    <!-- The navigation drawer -->
    <include layout="@layout/navigation_drawer"/>
</android.support.v4.widget.DrawerLayout>

对于主布局（即相关活动的 UI），我现在可以使用 Eclipse 的图形编辑器，因为所有内容都保存在一个文件中 main_layout.xml。
此外，我可以轻松地将导航抽屉包含在不同的活动中，而无需复制和粘贴代码。

Answer 5

我找到的最简单的解决方案是将预览 Theme.Holo.Light.Dialog.FixedSize 功能性和和平...

Answer 6

自定义视图很难在 eclipse 中的 UI 编辑器中正确显示（Android Studio 中的 UI 编辑器也是如此）。这是正常的。
