Actually, you can set a default style for TextViews (and most other built-in widgets) without needing to do a custom java class or setting the style individually.

If you take a look in themes.xml in the Android source, you will see a bunch of attributes for the default style for various widgets. The key is the textViewStyle (or editTextStyle, etc.) attribute which you override in your custom theme. You can override these in the following way:

Create a styles.xml:

<?xml version="1.0" encoding="utf-8"?><resources>    <style name="MyTheme" parent="android:Theme">        <item name="android:textViewStyle">@style/MyTextViewStyle    style>    <style name="MyTextViewStyle" parent="android:Widget.TextView">        <item name="android:textColor">#F00item>        <item name="android:textStyle">bolditem>    style>resources>

Then just apply that theme to your application in AndroidManifest.xml:

<application […] android:theme="@style/MyTheme">…

And all your text views will default to the style defined in MyTextViewStyle (in this instance, bold and red)!

This was tested on devices from API level 4 onward and seems to work great.

结论

测试可行

二、自测可行的另一种方式

        <item name="android:textColorPrimary">@color/text_color_defaultitem>        <item name="android:textColorSecondary">@color/text_color_defaultitem>        <item name="android:textColorTertiary">@color/text_color_defaultitem>

三、遇到的问题

　使用过程中，发现这个全局style对ListView中的TextView不生效

解决方案

不适用getApplicationContext,改使用Activity

//adapter = new ShopResultAdapter(getApplicationContext(), datas);//替换为Activityadapter = new ShopResultAdapter(this, datas);
