带参数的 WebView addJavascriptInterface 函数

我已经向 WebView 添加了 JavaScript 接口。

我可以使用所有没有参数的函数。

但是当我从 JavaScript 给出参数时。 WebView 不调用该函数。

See Code

JavaScript

        function getCellString(row, column) {
            return Report.getCellString(row,column);
        }

WebView

webView.addJavascriptInterface(new JavaScriptInterface(), "Report");

JavaScript 接口

public class JavaScriptInterface
{
public String getCellString(int row, int column)
{
    return row + "," + column;
}
}

我不确定是因为 String 返回类型还是函数的参数。

EDITED

我尝试不给 getCellString() 任何参数，但它仍然没有被调用。

这意味着问题出在返回类型上。我给出了 String 返回类型，它不是原始数据类型。

谁能告诉我应该用什么数据类型来代替字符串，以便它接受。

如果您更改方法参数int to String那么该函数应该可以从内部调用WebView:

public String getCellString(String row, String column)
{
    return row + "," + column;
}
