如何将光标背景设置为对EditText Android透明 [英] how to set cursor background transparent for EditText Android

问题描述

当我触摸用于在Android上更改文本的EditText时遇到此问题:

I'm having this issue when I touch an EditText for changing text on Android:

白色框出现在红色光标周围，并且我需要使它透明以正确显示EditText的行.我该如何更改?

A white frame appears around the red cursor, and I need it to be transparent for showing properly the line of the EditText. How do I change this?

代码:

<EditText
            android:id="@+id/login_user_name_text"
            android:textCursorDrawable="@null"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@color/black"
            android:textSize="16sp"
            android:inputType="textEmailAddress"
            android:imeOptions="actionNext"
            android:maxLines="1"
            android:hint="@string/email"
            android:maxLength="60"
            />

编辑:我可以通过替换以下内容来解决此问题:

I could fix it by replacing:

<item name="android:background">@color/white</item>

为

<item name="android:background">@color/transparent</item>

在styles.xml中

in styles.xml

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowDisablePreview">true</item>
        <item name="android:background">@color/transparent</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    </style>

推荐答案

另一种解决方案，如果您在使用工具栏时在SearchView中遇到EditText 的问题，则该解决方案有效.

Another solution, which works if you are having this problem with an EditText inside a SearchView while using a Toolbar.

1. 在您的活动XML中，将android:background="?attr/colorPrimary"属性添加到工具栏:

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:theme="@style/ToolBarStyle"
android:background="?attr/colorPrimary"
android:elevation="2dp" />

然后，从styles.xml中的ToolBarStyle中删除 <item name="android:background">@color/colorPrimary</item>.

Then, remove <item name="android:background">@color/colorPrimary</item> from your ToolBarStyle in styles.xml.

希望这可以帮助其他人为这种情况寻找解决方案.
