我有一个看起来像这样的常规按钮：
<Button
android:id="@+id/button1"
style="@style/ButtonInfo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:text="Button" />
ButtonInfo 如下所示：
<style name="ButtonInfo" parent="@android:style/Widget.Button">
<item name="android:background">@drawable/button_info</item>
<item name="android:textColor">@color/button_info_text</item>
<item name="android:textSize">16dip</item>
</style>
color/button_info_text.xml 看起来像这样：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"><shape>
<solid android:color="@color/black" />
</shape></item>
<item><shape>
<solid android:color="@color/white" />
</shape></item>
</selector>
我一直在错误日志中得到这个：
