Set EditText cursor color

For anyone that needs to set the EditText cursor color dynamically, below you will find two ways to achieve this.

First, create your cursor drawable:

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>

Set the cursor drawable resource id to the drawable you created (source)):

java

try {
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set(yourEditText, R.drawable.cursor);
} catch (Exception ignored) {
}

To just change the color of the default cursor drawable, you can use the following method:

java

    public static void setTextCursorColor(TextView textView, @ColorInt int color) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            final Drawable drawable = textView.getTextCursorDrawable();
            drawable.setTint(color);
            textView.setTextCursorDrawable(drawable);
        } else try {
            Field fCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
            fCursorDrawableRes.setAccessible(true);
            int   mCursorDrawableRes = fCursorDrawableRes.getInt(textView);
            Field fEditor            = TextView.class.getDeclaredField("mEditor");
            fEditor.setAccessible(true);
            Object   editor          = fEditor.get(textView);
            Class<?> clazz           = editor.getClass();
            Field    fCursorDrawable = clazz.getDeclaredField("mCursorDrawable");
            fCursorDrawable.setAccessible(true);

            Drawable[] drawables = new Drawable[2];
            Resources  res       = textView.getContext().getResources();
            drawables[0] = res.getDrawable(mCursorDrawableRes);
            drawables[1] = res.getDrawable(mCursorDrawableRes);
            drawables[0].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawables[1].setColorFilter(color, PorterDuff.Mode.SRC_IN);
            fCursorDrawable.set(editor, drawables);
        } catch (final Throwable throwable) {
            if (DEBUG) throw new RuntimeException("can't set text cursor color", throwable);
        }
    }
