答案 0 :(得分：0)
如果您没有编辑按钮的属性两次，一次是创建按钮，另一次是创建应答器样式，那么您是否检查了自己的样式？
例如：这里属性textColor被编辑了两次！
<Button
android:id="@+id/imageButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/imageButton1"
android:layout_centerHorizontal="true"
android:layout_marginTop="21dp"
android:background="@drawable/button_empty"
android:text="Email"
android:textColor="@Color/greycolor"
android:textStyle="@style/buttonFont" />
<style name="buttonFont">
<item name="android:textColor">#FFFFFF</item>
<item name="android:typeface">normal</item>
<item name="android:textSize">11dip</item>
</style>
