Answer 1

Try changing the code in webview activity like this. `

String pos="";
in = getIntent();

web2.setWebViewClient(new myWebClient());
web2.getSettings().setJavaScriptEnabled(true);

pos= in.getStringExtra("key");

if (pos.equals("0")) {
         web2.loadUrl("file:///android_asset/dia/diaone.html");
} else if (pos.equals("1")) {
         web2.loadUrl("file:///android_asset/dia/diatwo.html");
} else if (pos.equals("2")) {
         web2.loadUrl("file:///android_asset/dia/diathree.html");
}`

I'm posting this answer to my question to those friends that have a problem like mine. in each activity that contains listview i put this codes:

listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, final View view,
            int position, long id) {                        
            Intent intent = new Intent(getApplicationContext(), Dia_sec.class);
            switch(position){   
            case 0 :
                intent.setData(Uri.parse("file:///android_asset/can/canone.html"));
                break;
            case 1 :
                intent.setData(Uri.parse("file:///android_asset/can/cantwo.html"));
                break;
            case 2 :
                intent.setData(Uri.parse("file:///android_asset/can/canthree.html"));
                break;
            // etc
            }
            startActivity(intent);

and in my webview "dia_sec" i add this code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dia_sec);
    web2.loadUrl(getIntent().getDataString());

I had about 8 different activities that contains their own listview with different html files. and now i put code in activity and link them to my webview page. problem solved and now i have one webview that i use it to show all html files from different source and different listviews. Thanks alot every body to try help me in this way
