java.lang.UnsupportedOperationException：无法转换为dimension：type = 0x12

所以我的问题很奇怪。我一直收到这个错误：

java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x12

奇怪的是它只发生在4.1.2上。我测试了4.0.3,4.2.2,4.3和4.4。除4.1.2外，所有工作都完美。由于4.0.3工作，4.1.2在技术上也应该这样，所以我无法弄清楚出了什么问题。

这是我的activity_main.xml：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fitsSystemWindows="true"
tools:context="-removed name-">


<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">

    <!-- FrameLayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- ListView to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"

        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background" />
</android.support.v4.widget.DrawerLayout>

我搜索了所有类似的问题，但他们的解决方案对我不起作用。

答案 0 :(得分：33)

您应该以{{1​​}}样式添加android:windowTranslucentNavigation属性。

旧版本不支持。

答案 1 :(得分：4)

虽然有很多属性可能导致此崩溃，但由于很难修复，您可能只想检查?android:attr/listPreferredItemPaddingStart（以及所有其他~start和~endore属性）。 This question也表示windowTranslucentStatus和windowTranslucentNavigation是个问题。
