Custom palette

You need to define the basic color of the theme to adapt to your (app design) brand, and define your own color to use this color attribute in (material) Theme:

 

Custom Status Bar

 

With this material topic, you can easily customize the status bar, and you can also specify a color tone to adapt to your (app design) brand and provide sufficient contrast to display the white status bar icon. To customize the color of the status bar, you can use the android: statusBarColor attribute After inheriting the material topic. By default, the value of the android: statusBarColor attribute is android: colorPrimaryDark.

You can also define the format of the status bar. For example, if you want to display a transparent status bar on top of a photo, use a subtle dark gradient to make sure that the white status icon is visible. To do this, set the android: statusBarColor attribute to @ android: color/transparent (transparent) and adjust the window ID as needed. You can also use the Window. setStatusBarColor () method for animation or fading (fading ).

Note: the status bar should always have a clear definition with the toolbar, unless you show the rich image or media content between the edge and the edge, (or you) the gradient ensures that the icon is still visible.

 

 

 

Personal suggestions on topics

The elements in the XML layout can also define the android: theme attribute, which is a reference topic resource. The topic element modified by this attribute and any child element are used to change the topic color palette in a special interface.
