EditText就像Note

Question

我正在开发类似Note App的Android应用程序。所有的事情都很顺利。这是我的输出。

但是，当我输入缅甸语（东南亚语言之一）时，我遇到了一个问题，即我的EditText中的行与文本不一致，这是我的输出，

我用Google搜索并尝试了很多方法。但是，它无法帮助我。以下是我的代码。麻烦！

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);

    }

}
