我想更改按钮颜色，所以我使用了以下选择器

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_focused="true" android:color="#FFFF00"/>
    <item android:state_pressed="true" android:color="#FFFF00"/>

    <item>
        <shape>
            <gradient android:startColor="#ff00ff00" android:endColor="#bb00ff00" android:angle="270" />
            <stroke android:width="1dp" android:color="#bb00ff00" />
            <corners android:radius="3dp" />
            <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
        </shape>
    </item>

</selector>

并像这样使用它

<Button
    android:id="@+id/SODEOD"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="SOD/EOD" 
    android:background="@drawable/firstbuttoncolorstyle" 
    />

但这会导致应用程序崩溃

知道为什么会发生这种情况，以及如何解决它，这就是日志猫

尝试这个：

<?xml version="1.0" encoding="utf-8"?>


<item android:state_focused="true">
    <shape>
        <solid android:color="#FFFF00"/>
        <stroke android:width="1dp" android:color="#bb00ff00" />
        <corners android:radius="3dp" />
        <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
    </shape>
</item>
<item android:state_pressed="true">
    <shape>
        <solid android:color="#FFFF00"/>
        <stroke android:width="1dp" android:color="#bb00ff00" />
        <corners android:radius="3dp" />
        <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
    </shape>
</item>
<item>
    <shape>
        <gradient android:startColor="#ff00ff00" android:endColor="#bb00ff00" android:angle="270" />
        <stroke android:width="1dp" android:color="#bb00ff00" />
        <corners android:radius="3dp" />
        <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
    </shape>
</item>

它应该工作...

你需要有一个形状在每个<item>...
