在最新的Appcompact v21中，有一种改变光标颜色的新方法 只需要改变颜色，就像这样:

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette-->

    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">#088FC9</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">#088FC9</item>

    <!-- colorAccent is used as the default value for colorControlActivated
         which is used to tint widgets -->
    <!-- THIS IS WHAT YOU'RE LOOKING FOR -->
    <item name="colorAccent">#0091BC</item> 
</style>

然后将此样式应用于应用主题或活动。

更新:这种方法只适用于API 21+ 更新2:我不确定它可以工作的最低安卓版本。android版本测试:

2.3.7 - didn't work
4.4.4 - worked
5.0 - worked
5.1 - worked

迟到了，这是我的答案，

这是为那些不希望更改父主题中的colorAccent，但想更改EditText属性的人准备的!

这个答案演示了如何更改...... 底线颜色 光标的颜色 光标指针颜色(我使用我的自定义图像)..........使用样式应用到活动主题的编辑文本。

<android.support.v7.widget.AppCompatEditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hey" />

例子:

<style name="AppTheme.EditText" parent="@style/Widget.AppCompat.EditText">
    <item name="android:textColor">@color/white</item>
    <item name="android:textColorHint">#8AFFFFFF</item>
    <item name="android:background">@drawable/edit_text_background</item> // background (bottom line at this case)
    <item name="android:textCursorDrawable">@color/white</item>  // Cursor
    <item name="android:textSelectHandle">@drawable/my_white_icon</item> // For pointer normal state and copy text state
    <item name="android:textSelectHandleLeft">@drawable/my_white_icon</item>
    <item name="android:textSelectHandleRight">@drawable/my_white_icon</item>
</style>

现在创建一个可绘制的(edit_text_background)，为背景添加一个资源xml !您可以定制您想要的!

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:bottom="0dp"
        android:left="-3dp"   
        android:right="-3dp"
        android:top="-3dp">

        <shape android:shape="rectangle">
            <stroke
                android:width="1dp"
                android:color="@color/white"/>
        </shape>
    </item>
    </layer-list>

现在，正如您在活动主题中设置了此样式。

例子:

在您的活动中，您有一个主题，将此自定义editText主题设置为该主题。

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Your Theme data -->
    <item name="editTextStyle">@style/AppTheme.EditText</item> // inculude this
</style>

Edittext cursor color you want changes your color.
   <EditText  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textCursorDrawable="@drawable/color_cursor"
    />

然后创建可绘制的xml: color_cursor

<?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>

这里@Jared Rummler的编程setCursorDrawableColor()版本也适用于Android 9派。

@SuppressWarnings({"JavaReflectionMemberAccess", "deprecation"})
public static void setCursorDrawableColor(EditText editText, int color) {

    try {
        Field cursorDrawableResField = TextView.class.getDeclaredField("mCursorDrawableRes");
        cursorDrawableResField.setAccessible(true);
        int cursorDrawableRes = cursorDrawableResField.getInt(editText);
        Field editorField = TextView.class.getDeclaredField("mEditor");
        editorField.setAccessible(true);
        Object editor = editorField.get(editText);
        Class<?> clazz = editor.getClass();
        Resources res = editText.getContext().getResources();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            Field drawableForCursorField = clazz.getDeclaredField("mDrawableForCursor");
            drawableForCursorField.setAccessible(true);
            Drawable drawable = res.getDrawable(cursorDrawableRes);
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawableForCursorField.set(editor, drawable);
        } else {
            Field cursorDrawableField = clazz.getDeclaredField("mCursorDrawable");
            cursorDrawableField.setAccessible(true);
            Drawable[] drawables = new Drawable[2];
            drawables[0] = res.getDrawable(cursorDrawableRes);
            drawables[1] = res.getDrawable(cursorDrawableRes);
            drawables[0].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawables[1].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            cursorDrawableField.set(editor, drawables);
        }
    } catch (Throwable t) {
        Log.w(TAG, t);
    }
}

在Android中叫做colorAccent。

转到res -> values -> styles.xml添加

<item name="colorAccent">#FFFFFF</item>

If不存在。

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimary</item>
    <item name="colorAccent">@color/colorAccent</item> -- change this one
</style>

转到styles.xml并更改颜色重音，这将影响编辑文本框的光标
