Hi,

I want to save(export) contents of MyView, which extends TextView, into a bitmap.

I followed the code: [this][1].

It works fine when the size of the text is small.

But when there are lots of texts, and some of the content is out of the screen, what I got is only what showed in the screen.

Then I add a "layout" in my code:

private class MyView extends TextView{
    public MyView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public Bitmap export(){
        Layout l = getLayout();
        int width = l.getWidth() + getPaddingLeft() + getPaddingRight();
        int height = l.getHeight() + getPaddingTop() + getPaddingBottom();

        Bitmap viewBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(viewBitmap);


        setCursorVisible(false);
        layout(0, 0, width, height);
        draw(canvas);

        setCursorVisible(true);
        return viewBitmap;
    }
}

Now the strange thing happened:

The first time I invoke "export"(I use an option key to do that), I got contents only on the screen.

When I invoke "export" again, I got complete contents, including those out of the screen.

Why?

How to "export" a view, including contents cannot be showed on the screen?

Thank you!
