Which Layout is better to use?

In My Application i have to use the Calculator. The Different Button in Calculator should be like below image.

So, What should be better to implement such type of the Layout ? I think gridView is good, but while thinking about the "0" Button and the Button below "C" button, I dont know how to set it in to the gridview. So Anybudy tell me which one is the Best way to set this type of layout ? recently i have use the relative layout to set this layout. Please help me regarding this. and if the GridView is nice with this then tell me what should i have to do with that two buttons: one is "0" button and second is the Button that is below thee Button of "left errow".

You should use Relative layout as it will adjust itself with different resolution screens.

Use Relative layout because its have more functionality and also easier than other layout ................... and you have also set component toRightof and toLeftof and also many functionality////////
