Answer 1

You should use weight instead of dp. for example set weightsum on tablerow to a thousand and then divide up the weight on the EditTexts. This way you have more control than just relying on your calculations on dp. It could also be padding, look through dimensions and make sure that there is no padding or just override it by setting padding:0; on your tablerow
