Question

我在android 2.2中使用webView 我想将参数传递给js文件中的javascript函数，
我想要返回值到我的机器人

我的代码中有什么问题？

我的代码：

WebView webView1;
MyJavaScriptInterface myJavaScriptInterface1;

public void onCreate(Bundle savedInstanceState) {  
    webView1 = (WebView) findViewById(R.id.webView1);
    myJavaScriptInterface1 = new MyJavaScriptInterface(this);

    webView1.addJavascriptInterface(myJavaScriptInterface1,"AndroidFunction");
    EnableJavaScriptAndMultitouch(webView1);        
    webView1.loadUrl("file:///android_asset/P_001.html");       
}

public void EnableJavaScriptAndMultitouch(WebView mWebView) {
    mWebView.getSettings().setJavaScriptEnabled(true);          
    mWebView.getSettings().setSupportZoom(true);
    mWebView.getSettings().setBuiltInZoomControls(true);
}       

public void onLongPress(MotionEvent e) {
    webView1.loadUrl("javascript:SelectAyaInPosition("
            + String.valueOf(e.getX()) + "," + String.valueOf(e.getY())
            + ", 'black', 'red'");   
}
////////////////////////////////
public class MyJavaScriptInterface {
    Context mContext;

    MyJavaScriptInterface(Context c) {
        mContext = c;
    }

    public void getElementID(String ID) {
        Toast.makeText(mContext, ID, Toast.LENGTH_SHORT).show();
    }
}

my js文件在assets文件夹中，带有我的html文件

function ClearAll(defaultColor) 
{
    var allLinks = document.all.tags('a');
    for(var i = 0; i < allLinks.length; i++)
        allLinks[i].style.color = defaultColor;
}

function ColorAya(aya, sura, defaultColor, highlightColor) 
{
    ClearAll(defaultColor);
    var elementSelected = document.getElementById('a' + sura + '_' + aya);
    elementSelected.style.color= highlightColor;
}

function GetItemInPosition(x, y) 
{
    var elementSelected = document.elementFromPoint(x, y);
    return elementSelected.id;
}

function SelectAyaInPosition(x, y, defaultColor, highlightColor) 
{
    ClearAll(defaultColor);
    var elementSelected = document.elementFromPoint(x, y);
    elementSelected.style.color= highlightColor;
    showAndroidToast(elementSelected.id);
}

function showAndroidToast(toast) {
       AndroidFunction.getElementID(toast);
}
