Home App template and FrameLayouts from code

pskink · by **pskink** » Sun Mar 08, 2009 8:36 pm

hi,

created something that can be used as basic template for Home App.

it contains 2 x 3 virtual screens: each screen is FrameLayout created in code.

my problem is when i try to add something (see page_1_1) i cannot fill it to the whole page.

any hints?

I'm trying to figure it out, what I have found is that when you change the layout_width of one of the views inside page_1_1 to a fixed size, it does scale up as wanted.

The strange thing: the FrameLayout has a width of 320, but the linlayout inside it has only a width of 237.

Also another strange thing: when you make (for example) the TextView have layout_heigth="fill_parent" then the box doesn't change size, but the 2 buttons lay outside of the visible area of page_1_1. Strange stuff.

Ok, I think I found your mistake!

in HomeView.onLayout() you call mPages[][].measure() and specify the size in pixels, but it expects MeasureSpecs. So my sollution is to chagne you onLayout() to:

Using java Syntax Highlighting

        protected void onLayout(boolean changed, int l, int t, int r, int b) {
 
                Log.d(TAG, "onLayout " + r + " " + b + " count " + getChildCount());
 
                for (int x = 0; x<NUM_PAGES_X; x++) {
 
                        for (int y = 0; y<NUM_PAGES_Y; y++) {
 
                                int xx = x * mPageWidth;
 
                                int yy = y * mPageHeight;
 
                                //mPages[x][y].measure(mPageWidth, mPageHeight);
 
                                int widthMeasureSpec = MeasureSpec.makeMeasureSpec(mPageWidth, MeasureSpec.EXACTLY);
 
                                int heightMeasureSpec = MeasureSpec.makeMeasureSpec(mPageHeight, MeasureSpec.EXACTLY);
 
                                mPages[x][y].measure(widthMeasureSpec, heightMeasureSpec);
 
                                mPages[x][y].layout(xx, yy, xx+mPageWidth, yy+mPageHeight);
 
                        }
 
                }
Parsed in 0.033 seconds,  using GeSHi 1.0.8.4

I'm not sure if this solves the problem, but atleast the page_1_1 layout is now sized correctly.

thanx MrSnowflake, already found that i call measure with raw ints... (btw they could warn via Log.w if params are not cooked)

also fixed problem with individual page sizes

i wonder if anyone interested in making not google Home...
