Need help with Android TableLayout alignment
I'm trying to build a calculator layout using TableLayout, but the last two rows aren't aligning with the rest of the layout. Is there something wrong with my layout XML?
What I'm trying to do would be easier to accomplish in HTML (<td> with colspan or rowspan), so should I try converting this into a WebView?
Code is as follows: (Screenshot)

Answer
Your final TableRow has three cells (i.e., immediate children). The rest have four. Hence, they're not going to align unless you put an android:layout_span attribute in there somewhere to indicate which cell is absorbing the fourth.
