StoryboardsIn Xcode, Storyboard is a tool that allows us to visualize the application interface, you can first see the layout area of one or several iOS device screen sizes in the storyboard file, and then you can get from the component library (Object Library), you can also define the connection between screen layouts by dragging and dropping components into the layout area of the screen (such as buttons, pictures, text boxes, labels, etc.).In Xcode

After Class I compare the book and then search the information on the internet roughly summed up a bit.There are a few of the layouts we use in Android: LinearLayout (Linear layout), Relativelayout (relative layout), tablelayout (table layout), Absolutelayout (absolute layout), Framelayout (
controls in a tabular manner, which is not very commonly used.Modify the layout file code as follows:Each addition to a tablerow in the tablelayout means that a column is added to the table, and then each time a control is added to the TableRow, a column is added to the row, and thecontrol in the TableRow cannot specify a width. Android:inputtype= the "Textpassword" property to change the input box to the password input boxThe android:layout_span= "2" property indicates that the control occupie

the elements equal width.Next, we add a horizontal spacing constraint for the delete and Cancel buttons, select the Horizontal spacing constraint, modify its constant-bit standard, and modify the relation to greater Than or Equal:In this way, the button looks like the layout shown:As you can see, the buttons in the horizontal mode, look good, but in the vertical mode although there is no overlap, but the last button is not complete the whole word of reality.We can prioritize constraints, with a
; so 3:1:1 Billy shows. Then you will understand why when you set three Layout_weight to 1, 2, and 3, the following effect appears:The third one directly does not show, why? Let's take a look at the above method to calculate it: The system first assigns 3 TextView the width fill_parent they want, which means that each one fills his parent control, and here the width of the dead screen so this time the remaining space = 1 parent_width-3 parent_width=-2 a parent_width (parent_ Width refers to scr

1) fill_parentSetting the layout of a component to fill_parent will force the component to expand to fill as much space as possible within the layout unit. This is roughly the same as the DockStyle property of Windows controls. Setting a top layout or control for Fill_parent will force it to fill the entire screen.2) wrap_contentSetting the size of a view to Wrap_content will force the view to expand to show the entire content. Take the TextView and ImageView controls as an example, set to Wrap_
