Re: [android-developers] Re: 9.png file not spanning the LinearLayout when android:paddingBottom is specified

[Shri Borde]

That kind of makes sense. However, even if the padding gets overwritten,
the Button should still be over the red background since that is the
content area of the 9.png. Why would the Button be positioned on the drop
shadow (the non-content area of the 9.png)? Seems like there is some
undefined non-intuitive behavior happening whereas it would be preferable
for either of the defined padding to be applied (as that would the
intuitive behavior).

Re: [android-developers] Re: std::locale("").name() returns "C"

[Shri Borde]

I did ask on android-ndk and was told that the NDK does not support
locales. Will do locale processing in Java code.

Re: [android-developers] How can I check the value of wtf_is_fatal?

[Shri Borde]

I want to use wtf_is_fatal==1 as the gate for my expensive asserts since
the people who will set wtf_is_fatal (the dev team) will also be ok with
the slight slowdown caused by expensive asserts. Strictly speaking, these
should be two independent settings, but I was hoping to piggyback off of
wtf_is_fatal==1 so the devs do not have to worry about setting two
different bits. If I can not access wtf_is_fatal, I will probably add a
separate property.

Re: [android-developers] Intent.FLAG_ACTIVITY_REORDER_TO_FRONT does not work with PendingIntent

[Shri Borde]

I guess I can create a trampoline Activity which gets launched by clicking
on the notification icon, and it could then start MyActivity using
FLAG_ACTIVITY_REORDER_TO_FRONT. A bit of a pain which PendingIntent would
have supported itself, but I can give this a shot.

Re: [android-developers] GridView shows only one row with layout_height=WRAP_CONTENT

[Shri Borde]

TableLayout is for cases where you want a specific number of columns.
However, I would like the number of columns to adjust based on the width of
the screen/parent ViewGroup as done by GridLayout. And I do not actually
want the grid to scroll - I want its height to expand as much as needed to
display all the rows. So overriding GridView and modifying its behavior
seems like the best option.

Thanks for the pointers and the discussion.

Re: [android-developers] GridView shows only one row with layout_height=WRAP_CONTENT

[Shri Borde]

Actually, I am using a GridView in a ListView, not a LinearLayout. So the
entire grid can actually be displayed by scrolling the list (with the
Adapter architecture kicking in to display only those cells of the grid that
are visible on screen). I am using the GridView as a table, and it seems
reasonable to want to display the table in a ListView. There needs to be
some way to accomplish this.

One workaround I found was to override #onMeasure. This does show all the
rows of the GridView (on Gingerbread and Honeycomb)

public class MyGridView extends GridView {
  public MyGridView(Context context, AttributeSet attrs) {
super(context, attrs);
  }

  protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(
MeasureSpec.AT_MOST, MAX_EXPECTED_HEIGHT_OF_TABLE);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
  }
}

Re: [android-developers] Activity#onRetainNonConfigurationInstance vs Fragment#setRetainInstance

[Shri Borde]

It actually worked with Fragment#setRetainInstance. I just had to call
((ViewGroup) fragmentLayout.getParent()).removeView(fragmentLayout) before I
could reuse the views.

I got crashes in native code when I tried doing the same with
Activity#onRetainNonConfigurationInstance.
