```
public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
            switch(position){
         case 0: 

             Intent newActivity = new Intent(museum.this, museum_item.class);
           newActivity.putExtra("TXT_RESOURCE",R.string.infomuseum1);
            newActivity.putExtra("IMG_RESOURCE",R.drawable.infohistory);

            startActivity(newActivity);
             break;

```

and in the second i m using

```
 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.museum); 

Bundle extras = getIntent().getExtras();
String textResourceId = extras.getString("TXT_RESOURCE");
int imgResourceId = extras.getInt("IMG_RESOURCE");
