Android应用程序小部件存在问题

Question

当我尝试在模拟器中添加小部件时，会出现很多错误。可能的问题是什么？

以下是小部件的XML代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1" android:background="@layout/widget_layout">
    <FrameLayout android:id="@+id/frameLayout1" android:layout_height="200dp" android:layout_width="160dp" android:background="@drawable/framep">
        <RelativeLayout android:id="@+id/relativeLayout1" android:layout_width="match_parent" android:layout_height="match_parent">
            <TextView android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceMedium" android:layout_width="wrap_content" android:text="TextView" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_marginLeft="24dp" android:layout_marginTop="22dp" android:id="@+id/widDay" android:textColor="@color/colorBlack"></TextView>
            <TextView android:text="TextView" android:layout_below="@+id/widDay" android:layout_alignLeft="@+id/widDay" android:layout_marginTop="15dp" android:id="@+id/widText" android:layout_height="120dp" android:layout_width="115dp" android:textColor="@color/colorBlack"></TextView>
        </RelativeLayout>
    </FrameLayout>
</LinearLayout>

这里是错误信息：

Answer 1

错误信息指出无法加载可绘制对象。您的XML文件尝试将名为@layout/widget_layout的资源用作其背景。看起来您误将布局资源用作背景，而不是可绘制对象。
