EditText like Note

Question

I am developing Android Application like Note App. All of things were going pretty well.Here my output.

But, I have facing a problem that is the lines in my EditText become unequal with text when I typed Myanmar Language (one of South East Asia Language), here my output,

I googled and try many ways. But, it can't help me. Below are my code. Kindly!

LinedEditText.java

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

    // we need this constructor for LayoutInflater
    public LinedEditText(Context context, AttributeSet attrs) {
        super(context, attrs);

        mRect = new Rect();
        mPaint = new Paint();
        mPaint.setStyle(Paint.Style.STROKE);
        mPaint.setColor(0x800000FF);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        int height = getHeight();
        int line_height = getLineHeight();

        int count = height / line_height;

        if (getLineCount() > count)
            count = getLineCount();

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

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

            canvas.drawLine(r.left, baseline + 2, r.right, baseline + 2, paint);
            baseline += getLineHeight();
        }
        super.onDraw(canvas);

    }

}
