Answer 1

Linear Layoout: In linear layout,

1) the child elements are displayed in a linear style like horizontal or vertical.

2) it has two orientations, horizontal and vertical.

3) in vertical orientation, all child elements are arranged one below the other.

4) in horizontal orientation, all child elements are arranged sideways.

5) It can be used in making a login/signup activity, where we need a vertical alignement of textviews.

6) As it has weightsum attribute, different child element's height and width can be set relative to the whole layout.

Table Layout: In table layout,

1) the child elements are arranged according to rows and columns

2) it is same like the HTML tables and in this also, the rows has as many cells as the row having the most cells.

3) it can be used in showing tabular data to the user.

Frame Layout: In frame layout,

1) it is specifically used to display a single view on a specific area.

2) multiple childs can be there , but it will be very difficult to manage them in frame layout.

3) It can be used to show pictorial cards, title image, etc.

Nested Layout: In nested layout, multiples layouts are nested within each other to get the desired view and control over child elements. For ex: need to show some list of data with scroll property. In this case we need to use ListView with Scrollview.
