安卓:活动重启后如何恢复WebView内容？

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    webView.saveState(outState);
}

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

    webView = findViewById(R.id.webView);

    if (savedInstanceState != null) {
        webView.restoreState(savedInstanceState);
    } else {
        // 初始化WebView
        webView.loadUrl("https://www.example.com");
    }
}
