Android UI Development

Today I learned a few things about Android UI development

1. 6 large Layouts
2. Styles and themes → custom styles, themes
3. JUnit Unit Test
4. About Toast Popup Features

1. 6 large Layouts

• Relativelayout
• LinearLayout
• Framelayout frame layout-commonly used in game development, player, scratch card
• GridLayout Grid Layout-Calculators
• Tablelayout
  • The number of rows is controlled by TableRow, and several TR have several lines
  • No need to specify Layout_width\height

Can be contacted by a simple registration, login page.

　　2. Styles and Themes

Set style: style= "? android:attr/..."

Android:theme= "android:style/theme.dialog"----topic to add in Androidmanifest.xml.

• Custom styles

Create a style file under Res/values → add <resources> root node → add a <style> node within the root node → declare one or more <item> in a node

You can also implement custom styles by inheriting other already defined styles with the parent function--Should this be easier?

3.Use of Toast

• • To add a statement in mainactivity:
    • Toast.maketext (Mainactivity.this, "This is the pop-up window content", Toast.LENGTH.LONG). Show ();

Summary: Today's important content is the use of 6 large layouts and toasts, both of which are more commonly used in development, and are often used in UI development.
