点击share按钮后如何处理WebView中的外部链接？

import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    private WebView webView;

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

        webView = findViewById(R.id.webview);
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                if (isExternalLink(url)) {
                    // 处理外部链接，例如打开浏览器
                    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
                    startActivity(intent);
                    return true;
                }
                return false;
            }
        });

        webView.loadUrl("https://example.com");
    }

    private boolean isExternalLink(String url) {
        // 判断是否为外部链接的逻辑
        return !url.startsWith("https://yourdomain.com");
    }
}
