How to give onclick event to android menu?

Question

I have created android app using webview and added menu's into it.

In main.xml code

<item android:id="@+id/interview_tips" android:title="@string/interview_tips"></item>
<item android:id="@+id/interview_tips" android:title="@string/interview_tips"></item>
<item android:id="@+id/career_trend" android:title="@string/career_trend"></item>
<item android:id="@+id/video_hub" android:title="@string/video_hub"></item>

which is giving me menus like following image.

when I clicked on any menu I want to open a URL in same webview, How can I do it

I tried like this which is not working

    //menu click event
        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            // Handle item selection
            switch (item.getItemId()) {
            case R.id.action_settings:
            if (item.isChecked()) item.setChecked(false);
            else item.setChecked(true);
            mWebView.loadUrl("http://www.google.com");            
            return true;            
        case R.id.career_trend:
            if (item.isChecked()) item.setChecked(false);
            else item.setChecked(true);
            mWebView.loadUrl("http://www.google.com");        
            return true;
        default:
            return super.onOptionsItemSelected(item);
}
}

I'm bit new in android please give me any link , tutorial?

Answer 1

Use onOptionItemSelected if you use a Menu.

Also look a Menus guide and an Example : How to use menus.

And using a WebView required INTERNET permission, add below into AndroidManifest.xml.

<uses-permission android:name="android.permission.INTERNET" />

Also you can try enabling webview JS.

    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl("http://www.google.com");

UPDATE

First of all change your code

//menu click event
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
        case R.id.action_settings:
            mWebView.loadUrl("http://www.google.com");

        case R.id.career_trend:
            mWebView.loadUrl("http://www.google.com");
        }
        return true;
    }

TO

//menu click event
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
        case R.id.action_settings:
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.loadUrl("http://www.google.com");
        return true; 
        case R.id.career_trend:
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.loadUrl("http://www.google.com");
        return true;
        }
        return true;
    }

Secondary - make sure that your webview is present on screen. I mean is visible...

Third - check INTERNET PERMISSION in your manifest file.

and LAST! - make sure that your menu click listener is working. Just put Log into onOptionItemSelected method and check that he printed.

Answer 2

String[] mListOfUrls = { "http://google.com", "http://go.com", "http://gle.com" };

public void onItemSelected(AdapterView<?> parent, View view, 
        int pos, long id) {
   Log.wtf("URL", mListOfUrls[pos]);
   webView.loadUrl(mListOfUrls[pos]); 
}
