在Android的listview中的webview，javascript算术运算不起作用

Question

I am working in webview. I have a toggle button in my web page and when I click that button it will call the javascript function.
But it not properly working as expected. When I call that function when it come to addition operation it stuck. The only thing I done differently is I have webview inside listview.

function fnTogglePositive(obj){  
    oTable = document.getElementById("tblData");  
    obj.innerHTML = "ALL";  
    var i = 0;  
        fnCheck(0,6);   
    }           
    else{                           
    obj.innerHTML = "POSITIVE";         
    }
}

function fnCheck(i,n){  
    var k = parseInt(i) + 1;  
    if(i<n){  
       document.getElementById("txt").value = k ;  
    }  
    else  
       return 0;  
}

I loaded this javascript function in webview inside the list view. When I called the
fnTogglePositive function it's not calculating the value, when the webview is inside the listview.

I created a separate activity which contains only the webview its working fine.
I can able to figure out where it stuck. The function call happened but it stuck in calculating the
value. Why it stuck in this point?

Why this issue happened?

you need to build a bridge between you android code and JavaScript code.
