more luck here)
In an appwidget I have a somewhat complex layout with nested LinearLayouts
that serve as vertical columns. I want to add a setting that would allow
the user to choose a fixed or flexible widht for the columns (now it's
fixed at 38dip).
In XML terms, users could choose:
<item name="android:layout_width">38dip</item>
or
<item name="android:layout_width">wrap_content</item>
The following code will work if the LinearLayout belonged to an Activity,
but in an appwidget crashes because of the invalid cast ((Activity)
context):
private static void customizeWidget(Context context) {
int identifier;
int styleWidth = 38;
int newWidth = ph.autoAdjustableColumns() ?
ViewGroup.LayoutParams.WRAP_CONTENT : styleWidth;
for (int i = 1; i <= 7; i++) {
identifier = context.getResources().getIdentifier("day" + i + "_ll",
"id", context.getPackageName());
LinearLayout llDatesCol = (LinearLayout) ((Activity)
context).findViewById(identifier);
ViewGroup.LayoutParams params = llDatesCol.getLayoutParams();
params.width = newWidth;
llDatesCol.setLayoutParams(new LinearLayout.LayoutParams(params));
}
}
AFAIK it crashes because of limitations of the RemoteViews API, there is no
way to set parameters for layouts when they are accesed via RemoteViews.
I know I could load a different XML layout in each case, but since the
layouts would differ only in this line, I feel like it's a waste. Any other
solutions?
