关闭并再次单击后如何修复对话框中的错误？

Question

我正在开发 webview 应用程序，OnJsAlert 中的问题是当我单击 Dialog 它在关闭之后打开并再次单击它停止我的应用程序，抱歉我无法从调试.

这是我的MainActivity.class

@Override
public boolean onJsAlert(WebView view, String url, final String alertSource, final JsResult alertResult) {

    alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    alertDialog.setContentView(R.layout.activity_alert);

    alertDialog.setCancelable(true);

    TextView alertMessage = alertDialog.findViewById(R.id.alert_text);

    alertMessage.setText(alertSource);

    alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {

        @Override
        public void onCancel(DialogInterface dialog) {

            alertResult.cancel();

        }


    });

    alertDialog.show();

    return true;

}

你的 alertDialog 是在调用 public boolean onJsAlert(...) 方法之前创建的，当它第二次被调用时你得到 AndroidRuntimeException: requestFeature() must be called before adding content 因为你不能在创建的对话框中使用 requestWindowFeature()。您必须在此方法中创建新的对话框实例或重新使用全局定义的对话框。
