在 webview Android Studio 中打开链接

Question

你好，我已经在 android studio 的邮件活动中创建了 webview，现在我处于扫描仪活动中，当 APP 扫描任何具有链接的 QR 码时，它只会写入链接 但我想做的是在邮件活动中已创建的 Web 视图中打开链接。

让我把我的扫描仪文件放在这里

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scanner);
        scannView = findViewById(R.id.scannerView);
        codeScanner = new CodeScanner(this,scannView);
        resultData = findViewById(R.id.resultsOfQr);

        codeScanner.setDecodeCallback(new DecodeCallback() {
            @Override
            public void onDecoded(@NonNull final Result result) {

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        resultData.setText(result.getText());
//                        Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(result.getText()));
//                        startActivity(browserIntent);

                        Intent intent = new Intent(getBaseContext(), MainActivity.class);
                        intent.putExtra("myurl1", result.getText());
                        startActivity(intent);

                    }
                });

            }
        });


        scannView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                codeScanner.startPreview();
            }
        });
    }
    
    
            scannView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    codeScanner.startPreview();
                }
            });
        }

Mailactivity 中的 WEBVIEW

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    scanBtn = findViewById(R.id.scanBtn);

    MywebView = (WebView) findViewById(R.id.view2);
    WebSettings webSettings = MywebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    MywebView.loadUrl("https://google.com/APP/");

    MywebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.contains("tel:")) {
                Intent intent = new Intent(Intent.ACTION_CALL);
                intent.setData(Uri.parse(url));
                startActivity(intent);
                return true;
            }else{
                return false;
            }
        }
    });
    scanBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(getApplicationContext(),Scanner.class));
        }
    });

    String myrul = getIntent().getStringExtra("myurl1");
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            MywebView.loadUrl(myrul);
        }
    });

}

任何想法我该怎么做，任何帮助表示赞赏。 谢谢x

在你的 CodeScanner 回调中加载 WebView

runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    resultData.setText(result.getText());
                    MywebView.loadUrl(result.getText());
                }
            });
