Android: edittext multi-line display and all attributes

Edittext is one of our most commonly used controls. I have known how to use it for a long time, but how to use it well has encountered problems today. I would like to make a special conclusion to prevent such problems in the future.

<Edittext Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: gravity = "Left | top" Android: inputtype = "textmultiline" Android: background = "@ drawable/bg_input" Android: hint = "briefly describe the project content so that others can understand" Android: minlines = "6"/>

Explanation:

Android: inputtype = "textmultiline" // multiple lines can be displayed. Android: gravity = "Left | top" // enter the time standard in the upper left corner. Android: minlines = "6"
// Display at least 6 rows

Some Annotations of attributes are as follows:

Android: layout_gravity = "center_vertical" // you can specify the display position of the control: Top by default. Bottom is displayed in the center. Android: hint = "enter a number! "// Set the prompt information displayed on the space Android: Numeric = "integer" // you can only enter an integer. If it is a decimal Android: singleline = "true" // you can specify a single-line Input. If this parameter is set to true, text is not automatically wrapped. Android: Gray = "TOP" // the pointer is at the first position of the first row in multiple rows. setselection (ET. length (); // adjust the cursor to the last line Android: AutoText // automatically spell help Android: Capitalize // The first letter uppercase Android: digits // set to only accept certain numbers Android: singleline // whether a single line or multiple lines are supported. Press enter to leave the text box or Add a new line Android: Numeric // only numbers Android: Password // password Android: phonenumber // enter the phone number Android: editable // whether to edit Android: autolink = "all" // set the text hyperlink style. When you click a URL, the URL Android: password = "true" // you can only enter a password.
