It remind me of considering some margin space, so i change my code as below:
protected void onDraw(Canvas canvas) {
canvas.drawColor(paperColor);
int count = getLineCount();
int height = this.getMeasuredHeight();
int line_height = this.getLineHeight();
int page_size = height / line_height + 1;
if (count < page_size) {
count = page_size;
}
* int posY = 5; // i guess the margin-top may be 5 px :)*
for (int i = 1; i < count; i++) {
*posY += line_height;*
canvas.drawLine(0, posY, getRight(), posY, linePaint);
canvas.save();
}
super.onDraw(canvas);
canvas.restore();
}
finally it looks right, so i'm sure there is a margin space between my
EditText and the default view , but i have no idea about how to get this
height? so i hard code it 5 px
any suggestion?
