Why android:layout_width=”0px” for fragments?

Question

The layout width is always zero in fragment examples. What is behind this value?

Answer 1

This has worked for me:

1. Sum all weights in the layout. In the example that Squonk posted, there are 2 fragments and total weight is 3.

2. The fragment ArticleListFragment has a weight=1, meaning that the size will be 1/3 ( 3 is the total weight) of the screen.

3. The fragment ArticleReaderFragment has a weight =2, meaning that the size will be 2/3 of the screem.

Hope it helps.
