android - 在 SystemWebViewClient.java 文件 cordova 中的 onReceivedSslError 中将上下文传递给警报对话框

Question

我想在类的onReceivedSslError方法中显示警报对话框。SystemWebViewClient那么我应该将参数传递给警报对话框。我尝试了“ this， ” MainActivity.this，view.this但它不起作用。提前致谢。

目前我正在使用的代码

public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) {
    AlertDialog.Builder builder = new AlertDialog.Builder(Tab1Activity.this);
    AlertDialog alertDialog = builder.create();
    String message = "SSL Certificate error.";
    switch (error.getPrimaryError()) {
        case SslError.SSL_UNTRUSTED:
            message = "The certificate authority is not trusted.";
            break;
        case SslError.SSL_EXPIRED:
            message = "The certificate has expired.";
            break;
        case SslError.SSL_IDMISMATCH:
            message = "The certificate Hostname mismatch.";
            break;
        case SslError.SSL_NOTYETVALID:
            message = "The certificate is not yet valid.";
            break;
    }

    message += " Do you want to continue anyway?";
    alertDialog.setTitle("SSL Certificate Error");
    alertDialog.setMessage(message);
    alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // Ignore SSL certificate errors
            handler.proceed();
        }
    });

    alertDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

            handler.cancel();
        }
    });
    alertDialog.show();
}

问题不在于您传递的上下文，而是您试图从不允许的地方显示对话框。

您可以显示通知或在活动类中创建 showDialod() 函数，然后从 SystemWebViewClient 类调用它。

希望能帮助到你。
