How do I get the `layout_weight` of a TextView?

Question

I have a TableLayout and a row with a couple TextViews. I want to find the layout_weight of the TextView but I cant figure out how. I've tried the following:

TableRow.LayoutParams lp = tv1.getLayoutParams();

and:

ViewGroup.LayoutParams lp = tv1.getLayoutParams();

In the first case I get a type mismatch: "Cannot convert from ViewGroup.LayoutParams to TableRow.LayoutParams", and the second case works fine, however ViewGroup.LayoutParams doesn't have a weight field.

All the different types of LayoutParams are confusing, I'm never sure which to use where.

Try this

TextView text = new TextView(v.getContext());
text.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f));

Setting the `LayoutParams` isn't a problem. It works with both `TableRow` and `TableLayout` `LayoutParams`. The problem is I can't get the `layout_weight` because `getLayoutParams()` returns a `ViewGroup.LayoutParams` object which doesn't include weight. – linitbuff Jan 16 '13 at 06:34

You almost had it with your first try. You just need to cast to the correct type:

TableRow.LayoutParams lp = (TableRow.LayoutParams) tv1.getLayoutParams();

Any subclass of LinearLayout.LayoutParams (including TableRow.LayoutParams) will have a weight field.
