- Layout: XamarinAndroidWorkshop Solution Dialogs and Toast : (1) TimeandDateDialog Solution (2) DialogToast Solution
- Layout in android is a View group type, which can contain views inside it. So basically it is a container, based on requirement. Anything that can be a view can be a child of Layout. A custom layout could also be created for custom requirement, as the Layouts are derived from ViewGroup class.
- A Linear Layout could have children displaying either in horizontal or in vertical. Let’s have a layout example we would do for all the above layouts. We would have two EditText controls with describing TextView and a Button control to do something.
- A Relative Layout has always relationship with its children. You can also say that, children of Relative Layout are related to layout. This is one of the complicated layouts you would ever see.The reason is too many properties to set for child and parent to get what we want.
- This is one of the most used Layouts. As the name says the View is organised in Rows and Columns.However to have columns in the Row,we need to use a TableRow,which would conta in the children.The number of children present in a TableRow,is exactly the number of Columns present in the Row. Also,it’s not obvious that the number of columns present in first row would be same in the following Row. That’s the poor thing about it; each row’s column count is dependent on its children count.
- Each child view in Frame Layout starts from the Top Left of the Layout.
- A dialog is a small window that is prompted to the user to make a decision or enter additionalinformation.
