cannot change background color of custom editText in android

i quoted custom editText because i want to draw lines in edittext so i have this class 

public class LinedEditText extends android.support.v7.widget.AppCompatEditText {
private Rect mRect;
private Paint mPaint;
private int COLOR;

public LinedEditText(Context context, AttributeSet attrs) {
    super(context, attrs);

    mRect = new Rect();
    mPaint = new Paint();        
    mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
    SharedPreferences sh= PreferenceManager.getDefaultSharedPreferences(context);
    String co=sh.getString("line_color", String.valueOf(R.color.blue_line));
    mPaint.setColor(getResources().getColor(Integer.parseInt(co))); //SET YOUR OWN COLOR HERE
}

@Override
protected void onDraw(Canvas canvas) {
    //int count = getLineCount();

    int height = getHeight();
    int line_height = getLineHeight();
    int count = height / line_height;
    if (getLineCount() > count)
        count = getLineCount();//for long text with scrolling

    Rect r = mRect;
    Paint paint = mPaint;
    int baseline = getLineBounds(0, r);//first line

    for (int i = 0; i < count; i++) {

        canvas.drawLine(r.left, baseline + 1, r.right, baseline + 1, paint);
        baseline += getLineHeight();//next line
    }
    super.onDraw(canvas);
}

}

and i used this class in xml and in another class (MainActivity) without any problem but when i try to change color pro grammatically is not change even if i change that in xml ,is not change

xml :

 <my.app.haythamayyash.note.LinedEditText
        android:layout_width="match_parent"
        android:inputType="textMultiLine"
        android:scrollbars="vertical"
        android:gravity="top|start"
        android:ems="10"
        android:id="@+id/detail2"
        android:layout_height="463dp"
        android:backgroundTint="@android:color/transparent"
        android:textColor="@android:color/black"
        android:minHeight="510dp"/>

i try that by added android:background="@color/gray" but no thing changed , and i try to change that in java by 

ed.setBackgroundColor(Color.parseColor("#ffffff"));

and ed.setBackgroundResource(R.color.gray); but nothing change i guess the issue in LinedEditText class because i changed other editText (not LinedEditText) and its work .. how to change background color of this editText (programmatically) ??

Use this code in LinedEditText in onDraw() method for changing its color:

 canvas.drawColor(Color.BLACK);

or by resources layout file you can do this like:

app:backgroundTint="@android:color/holo_red_dark"
