如何在我的贴纸应用程序中添加"View More“按钮，并将其与Android中的playstore应用程序相链接

import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    private static final String PLAY_STORE_PACKAGE_NAME = "com.android.vending";
    private static final String PLAY_STORE_APP_URL = "https://play.google.com/store/apps/details?id=com.example.myapp";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button viewMoreButton = findViewById(R.id.view_more_button);
        viewMoreButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Check if Play Store app is installed
                PackageManager packageManager = getPackageManager();
                try {
                    packageManager.getPackageInfo(PLAY_STORE_PACKAGE_NAME, PackageManager.GET_ACTIVITIES);
                    // Play Store app is installed
                    openPlayStore();
                } catch (PackageManager.NameNotFoundException e) {
                    // Play Store app is not installed
                    openPlayStoreWebsite();
                }
            }
        });
    }

    private void openPlayStore() {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse("market://details?id=com.example.myapp"));
        startActivity(intent);
    }

    private void openPlayStoreWebsite() {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(PLAY_STORE_APP_URL));
        startActivity(intent);
    }
}
