Use the Java class library to implement the Android custom tab (CUSTOM TABS) framework
Custom Tabs is a framework that implements the browser tab function in Android applications.It provides a similar interface and interaction method similar to the browser tab, and allows the application to display the web content on the tab page.
To achieve a custom tab frame, we can use the CustomTabs class library provided by Android.Here are the steps required to implement this function:
1. Add dependency library: Add the following dependencies in the project's built.gradle file:
dependencies {
implementation 'androidx.browser:browser:1.3.0'
}
2. Create a custom tab page: Create a Java class called Customtabutils, and write the following code in it:
import android.content.Context;
import android.net.Uri;
import androidx.browser.customtabs.CustomTabsIntent;
public class CustomTabUtils {
public static void openCustomTab(Context context, String url) {
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(context, Uri.parse(url));
}
}
3. Use a custom tab page in the application: where you need to open the custom tab page, call the OpenCUSTOSTAB method of the CustomTabutill class and pass a URL parameter.For example, when you click on a button, open the custom tab, and you can use the following code in the click event processing code of the button:
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
CustomTabUtils.openCustomTab(MainActivity.this, "https://www.example.com");
}
});
The above code will use the CustomTabsintent to build a custom tab page and use the inlet URL to open the tab.
Remark:
The URL used in the above code is only used as an example. You can change the URL according to your actual needs.
Please note that in order to use a custom tab, your application must integrate Chrome browser or other browsers that support Custom Tabs.You can integrate the Chrome browser by adding the following code to the Application element in the manifest file of the application:
<meta-data
android:name="android.support.customtabs.trusted.EXPECTED_PACKAGES"
android:value="com.android.chrome" />
In the above code, replace com.android.chrome to the name package of the Chrome browser you want to integrate.
Now you have learned about the process of using the Java library to implement the Android custom tab framework.You can adjust the code according to your needs and add appropriate functions and styles.I hope this article can help you achieve a custom tab function in Android applications.
