Detailed explanation of Android custom tab (Custom Tabs) framework

Detailed explanation of Android custom tab (Custom Tabs) framework Overview: In Android applications, the tab is a commonly used user interface element that can be used to display multiple pages on the same screen at the same time.However, the native Android tabs may not meet specific design needs.To solve this problem, Android provides a custom tab page (CUSTOM TABS) framework, allowing developers to create and display tabs based on their own design requirements. Working principle of custom tab frame framework: The custom tab frame uses the powerful function of the Chrome browser. By using the chrome browser instance in the application, the display and management of the custom tab page can be realized. The benefits of using the custom tab page frame: 1. Provide a smoother browsing experience: The custom tab page is based on the Chrome browser engine, which can provide more efficient and smooth pages loading and rendering effects. 2. Modularity: Developers can choose only some functions in the frame according to their own needs without needing to introduce the entire WebView control. 3. Safety: The custom tab frame uses the Chrome security mechanism to avoid pose a threat to user equipment security due to the vulnerability of the internal browser. Steps to use the custom tab page: 1. Add dependencies: In the built.gradle file of the project, add the relying on the Custom Tabs library: implementation 'androidx.browser:browser:1.3.0' 2. Create an Intent of a custom tab: Use the CustomtabsIintent.builder to build an Intent for starting the tab and set the necessary attributes (such as display mode, toolbar color, etc.). CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder(); builder.setToolbarColor(Color.BLUE); CustomTabsIntent customTabsIntent = builder.build(); 3. Start a custom tab: Start the custom tabs through the CustomtabsInInIntent.launchurl () method, and specify the URL to be loaded. customTabsIntent.launchUrl(context, Uri.parse("https://example.com")); Custom label page advanced configuration: 1. Add the toolbar button: Through the addtoolBaritem () method of the CustomTabsintent.builder, you can add the custom operation button to the tab toolbar. builder.addToolbarItem(int id, Drawable icon, String description, PendingIntent pendingIntent); 2. Add menu item: Through the adddefaultsharemenuitem () method of Customtabsintent.builder, you can add the default sharing button to the toolbar menu on the tab. builder.addDefaultShareMenuItem(); 3. Customized exit animation: Through the setexitanimations () method of Customtabsintent.builder, you can set a custom exit animation. builder.setExitAnimations(context, R.anim.slide_in_left, R.anim.slide_out_right); 4. Add custom button: Through the setActionButton () method of the CustomtabsInIntent.builder, you can add a custom button to the toolbar on the tab page. builder.setActionButton(Drawable icon, String description, PendingIntent pendingIntent); Summarize: The custom tab frame framework is a powerful tool provided by Android that can be used to create and display customized tab pages, providing a smoother, secure and flexible user experience.Through the above steps and configurations, developers can build their own tab application according to their own needs.
