跟着教程写todoapplication：

所需图标样式：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="true" android:state_focused="true">
        <shape android:shape="rectangle">
                <solid android:color="@color/white"/>
                <stroke android:width="1dp" android:color="@color/colorPrimary"/>
                <conrers android:radius="5dp"/>
        </shape>
    </item>


    <item android:state_enabled="true" >
        <shape android:shape="rectangle">
            <solid android:color="@color/white"/>
            <stroke android:width="1dp" android:color="@color/lightGray"/>
            <corners android:radius="5dp"/>
        </shape>
    </item>
</selector>

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24"
    android:viewportHeight="24"
    android:tint="?attr/colorControlNormal">
    <path
        android:fillColor="@android:color/white"
        android:pathData="M19,13h-6v6h-2v-6H5v-2h6V5h2v6h6v2z"/>
</vector>

无信息时候的背景：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="146dp"
    android:height="116dp"
    android:viewportWidth="146"
    android:viewportHeight="116">
    <path
        android:fillColor="@color/lightGray"

</vector>

<vector android:height="24dp" android:tint="#000000"
