How can I change EditText's cursor's color programmatically ?
In android 4.0 and above, cursor color is white. and if EditTexts background is also white, it becomes invisible.

In your EditText properties, there is an attribute android:textCursorDrawable 
Now set it to @null like,
android:textCursorDrawable="@null"
So now your EditText Cursor is same as your EditText TextColor.

    I found a way to fix this. It is not the greatest solution, but it works.
Unfortunately, I can only use static color for the cursor color.
First, I define a black cursor in drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="#ff000000"/>
    <size android:width="1dp"/>
</shape>
Next I define a sample EditText in layouts.
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textCursorDrawable="@drawable/blackpipe"
         >
    </EditText>
When I want to create an EditText at runtime, I use this:
AttributeSet editText30AttributeSet = null;
int res = getResources().getIdentifier("edit30", "layout", getPackageName());//edit30 is EditText layout
XmlPullParser parser = getResources().getXml(res);
int state=0;
do {
    try {
        state = parser.next();
    } catch (Exception e1) {
        e1.printStackTrace();
    }       
    if (state == XmlPullParser.START_TAG) {
        if (parser.getName().equals("EditText")) {
            editText30AttributeSet = Xml.asAttributeSet(parser);
            break;
        }
    }
} while(state != XmlPullParser.END_DOCUMENT);
EditText view = new EditText(getContext(),editText30AttributeSet);
Now you have an EditText view that has a black cursor. Maybe somebody can improve on my solution so that the cursor can be changed at runtime.
Here is, what I think, a better solution than what @Adem posted.
Java:
try {
    // https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set(yourEditText, R.drawable.cursor);
} catch (Exception ignored) {
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <solid android:color="#ff000000" />
    <size android:width="1dp" />
</shape>
 
    
    improving on Jared Rummler's answer
Java:
try {
    // https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set(yourEditText, R.drawable.custom_cursor);
} catch (Exception ignored) {
}
create custom_cursor.xml in res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <solid android:color="#ff000000" />
    <size android:width="1dp" />
</shape>
XML:
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textCursorDrawable="@drawable/custom_cursor"
     >
</EditText>
 
    
    What about the styles.xml using AppCompat-v7?
<item name="colorControlNormal">@color/accentColor</item>
<item name="colorControlActivated">@color/accentColor</item>
<item name="colorControlHighlight">@color/accentColor</item>
Works for me (this example is simplistic).
 
    
    You may Set the android:textCursorDrawable attribute to @null that will result in the use of android:textColor as the cursor color.
Attribute textCursorDrawable is available in API level 12 and higher...
Thanks...
 
    
     
    
    Set Via AppTheme
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"><!-- Customize your theme here. -->
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:spinnerStyle">@style/spinner_style</item>
    <!--Add This-->
    <item name="editTextStyle">@style/EdittextStyle</item>
    <item name="android:dropDownListViewStyle">@style/SpinnerStyle</item>
</style>
<!--New EditText Style-->
<style name="EdittextStyle" parent="Widget.AppCompat.EditText">
    <item name="android:background">?attr/editTextBackground</item>
    <item name="android:textColor">?attr/editTextColor</item>
    <item name="android:textAppearance">?android:attr/textAppearanceMediumInverse</item>
    <!--<item name="android:textCursorDrawable">@drawable/abc_text_cursor_material</item>-->
    <item name="colorControlNormal">@color/colorAccent</item>
    <item name="colorControlActivated">@color/colorAccent</item>
    <item name="colorControlHighlight">@color/colorAccent</item>
</style>
 
    
    So, here's the final version - doesn't need the XML and works as @null but programmatically:
try {
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set((TextView)yourEditText, 0);
} catch (Exception ignored) {
}
The only problem is that it may stop working one day with some new version of Android.
PS I tested it on 4.1.2 to 5.1.
