我有一个奇怪的问题,如果我尝试将 Drawable xml 文件分配给布局文件,那么应用程序就会崩溃。但是,如果我改用标准颜色代码,它就可以正常工作。
笔记。我几乎使用新的模板 Master/Detail Flow,我还在基本布局的 Root 视图上分配了一个 xml drawable,它工作正常。问题是将 Drawable xml 分配到列表片段的布局 (list_content.xml)
这是我的背景 xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FF000000"
android:endColor="#FF555555"
android:type="linear"
/>
</shape>
我的布局是
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background_lhs"
>
<LinearLayout android:id="@+id/progressContainer"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"
android:gravity="center" >
<ProgressBar style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Loading"
android:paddingTop="4dip"
android:singleLine="true" />
</LinearLayout>
<FrameLayout android:id="@+id/listContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ListView android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawSelectorOnTop="false"
/>
<TextView android:id="@+id/internalEmpty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceLarge" />
</FrameLayout>
</FrameLayout>
^ 在最顶部,您会找到backgrounds
参考,当我将其更改为正常值(例如#000000
)时,它就起作用了。我也尝试过在drawable xml中使用纯色作为形状,但仍然会导致崩溃。原木猫除了没有什么帮助外Fatal signal 11 (SIGSEGV) at 0x00000004 (code=1), thread 2521
。没有明显的迹象可以告诉我 logcat 有什么问题,也没有内存警告或错误。
这是请求的logcat
