更改EditText下划线的颜色 [英] Changing the color of EditText's underline

问题描述

我试图借助此线程来更改EditText的下划线颜色

我做了同样的事情-这是EditText，其中android:background设置为@drawable/edt_bg_selector.

I did the same thing - this is the EditText with the android:background set as @drawable/edt_bg_selector.

<EditText
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:ems="10"
         android:id="@+id/editText4"
         android:layout_weight="1"
         android:elevation="0dp"
         android:background="@drawable/edt_bg_selector" />

我的edt_bg_selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/edt_bg_selected" />
    <item android:state_focused="false" android:drawable="@drawable/edt_bg_normal" />
</selector>

... edt_bg_normal.xml ...

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle" >
            <stroke
                android:width="1px"
                android:color="@color/colorWhite" />

            <solid android:color="#00FFFFFF" />

            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />
        </shape>
    </item>
</layer-list>

...和最后一个edt_bg_selected.xml.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle" >
            <stroke
                android:width="1px"
                android:color="@color/colorWhite" />

            <solid android:color="#00FFFFFF" />

            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />
        </shape>
    </item>
</layer-list>

使用此代码，我可以看到下划线的颜色在Android Studio的设计编辑器中已变为白色.但是，当我在android设备上运行此项目时，尚未进行更改.选定的EditText的下划线是我的primaryColor，未选定的EditText是黑色.

With this code I can see the color of underline has changed to white in Design Editor of Android Studio. But when I run this project on android device, the changes haven't been made. Selected EditText's underline is my primaryColor and unselected EditText is black.

Android Studio设计编辑器:

在android设备上运行的项目:

这与我的应用程序的选定主题有关系吗?还是我想念什么?

Does this have anything to do with the selected theme of my application? Or what did I miss?

推荐答案

<EditText
    android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Something or Other"
            android:backgroundTint="@android:color/holo_green_light" />

注意:仅适用于AP lvl 21或更高版本.

Note: only works with AP lvl 21 or higher.
