今天写代码,要edittext为空的时候给出提示,用android自带的setError函数,发现文本的颜色和背景的颜色相同,查了一下资料,贴出solution:
在 res/values/styles.xml文件中,在自定义主题里加入一个item:
<item name="android:textColorPrimaryInverse">@android:color/primary_text_light</item>
完整文件内容如下:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="@android:style/Theme.Light.NoTitleBar">
<item name="android:textColorPrimaryInverse">@android:color/primary_text_light</item>
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
<style name="LoginFormContainer">
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:padding">16dp</item>
</style>
<style name="edittext_style" parent="@android:style/Widget.EditText">
<item name="android:background">@drawable/bg_edittext</item>
<item name="android:paddingLeft">10dip</item>
<item name="android:paddingTop">8dip</item>
<item name="android:paddingBottom">8dip</item>
</style>
</resources>
这样,提示的内容颜色会变为黑色
还不知道怎样改popup的背景颜色,不喜欢默认的白色。
