Android support custom tabs (CUSTOM TABS) framework in Java Class Library
Android support custom tabs (CUSTOM TABS) framework in the Java class library
Overview:
Custom Tabs is a framework in Android that is used to open a web link in the application and provide a customized experience.This framework provides many functions and configuration options so that developers can customize the appearance and behavior of the tab pages according to the needs of the application.In this article, we will explore the use and related configuration of the Android custom tab framework in the Java class library.
Configuration step:
To implement the custom tab function in your Android application, you need to configure it according to the following steps:
1. Add dependencies:
Add the following dependencies to your `build.gradle` file to introduce the Custom Tabs library:
groovy
dependencies {
implementation 'androidx.browser:browser:1.3.0'
}
2. Create an Activity in the application:
Create an Activity that inherits the `AppCompatActivity`, and define a method in it to load and display the custom tab.This will be the entrance point of your custom tab.
import androidx.appcompat.app.AppCompatActivity;
import androidx.browser.customtabs.CustomTabsIntent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
private Button openCustomTabButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
openCustomTabButton = findViewById(R.id.open_custom_tab_button);
openCustomTabButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
openCustomTab();
}
});
}
private void openCustomTab() {
String url = "https://www.example.com";
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(this, Uri.parse(url));
}
}
The above code demonstrates the basic process of opening a web link in the custom tab page Activity.When the user clicks the button, the `OpenCustomtab () method will be called. This method uses the Customtabsintent to create a custom tab object, and use the specified URL to start the custom tab.
3. Add layout file:
Create a new layout file called `activity_main.xml`, and add a button to trigger the operation of opening the custom tab.
<Button
android:id="@+id/open_custom_tab_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Open Custom Tab"
android:layout_gravity="center" />
In the layout file, we added a button with the ID of `Open_custom_tab_button`. When the user clicks the button, it will trigger the operation of the custom tab page.
4. Run application:
After completing the above configuration, you can run your application and open the custom tabs when you click the button.
Summarize:
Through the above configuration, you can use a custom tab page framework in your Android application to open the web link to provide a more personalized and customized experience.You can also further configure according to your own needs, such as adding a custom button and processing back.It is hoped that this article will help the use and related configuration of the Android custom tabs in the Java library.
