推荐答案

您必须创建/修改您自己的 NinePatch 图像以替换默认图像，并将其用作 EditText 的背景.如果您查看您的 SDK 文件夹，在您的平台下，然后是 res/drawable，您应该会找到 EditText 焦点状态的 NinePatch 图像.如果这就是您想要更改的全部内容，您可以将它拉入 Photoshop 或您拥有的任何图像编辑软件，然后将橙色更改为您选择的颜色.然后将其保存到 drawable 文件夹中，并构建一个新的 StateListDrawable，例如如下所示:

You'll have to create/modify your own NinePatch image to replace the default one, and use that as the background of your EditText. If you look in your SDK folder, under your platform, then res/drawable, you should find the NinePatch image for the EditText focus state. If that's all you want to change, you can just pull it into Photoshop, or whatever image editing software you have, and change the orange color to a color of your choosing. Then save that into your drawable folder, and build a new StateListDrawable, for example something like the below:

edittext_modified_states.xml

<?xml version="1.0" encoding="utf-8"?>
<selector 
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item 
        android:state_pressed="true"
        android:drawable="@android:drawable/edittext_pressed" 
        /> <!-- pressed -->    
    <item 
        android:state_focused="true"
        android:drawable="@drawable/edittext_focused_blue" 
        /> <!-- focused -->    
    <item 
        android:drawable="@android:drawable/edittext_normal" 
        /> <!-- default -->
</selector>

我不知道 EditText 的默认 NinePatches 的实际名称，因此根据需要替换它们，但这里的关键是仅使用 @android:drawable 图像作为这些图像您尚未修改(或者您可以将它们复制到项目的 drawable 文件夹中)，然后将修改后的 drawable 用于您的聚焦状态.

I don't know offhand the actual names for the default NinePatches for the EditText, so replace those as necessary, but the key here is to just use the @android:drawable images for the ones you haven't modified (or you can copy them over to your project's drawable folder), and then use your modified drawable for your focused state.

然后您可以将此 StateListDrawable 设置为 TextView 的背景，如下所示:

You can then set this StateListDrawable as the background for your TextView, like so:

<TextView
    android:background="@drawable/edittext_modified_states"
