how to set cursor background transparent for EditText Android

问题

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

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?

code:

<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"
            />

EDIT: I could fix it by replacing:

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

for

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

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>

Sorry for the late,
I think you have
<item name="android:popupBackground">@color/white</item> in your style from v21,
just remove it, It may solve your problem

回答2:

better using @android:color/transparent instead of null on the android:textCursorDrawable="@android:color/transparent"

回答3:

Add the following to your EditText XML instead of null;

android:textCursorDrawable="@drawable/colorcursor"

Then, create a file called colorcursor.xml inside your drawable folder;

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:width="3dp" />
    <solid android:color="#FFFFFF"  />
</shape>

Setting android:background to transparent didn't do the trick for me.

In my case I set a theme to the parent viewgroup that defined the background to be a certain color, so it was applied to the EditText as well. Making sure that the background was just set for the parent solved it.

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

In your activity XML add the android:background="?attr/colorPrimary" attribute to Toolbar:

<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" />

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

Hope this helps someone else looking for a solution for this particular case.
