Click ListView item, opens activity that shows layout depending on what item was clicked?

Question

in my app, I have a MainActivity that consist of many items that can be clicked(ListView). If an item is clicked, I want it to open the next activity(ex. NextActivity) that displays an xml layout which is relative to which item the user has clicked on the previous screen. This is my complete MainActivity code:

public class MainActivity extends ListActivity {
private LayoutInflater mInflater;
private Vector<RowData> data;
RowData rd;

static final String[] title = new String[] {
    "Temaki Sushi", "Oyakodon", "Okonomiyaki", "Tofu Dango", "Oden", //5
    "Nikujaga", "Yellowtail Teriyaki", "Tendon", "Tonjiru", "Sukiyaki", //10
    };

private Integer[] releaseid =  {
      R.drawable.old, R.drawable.old, R.drawable.old, R.drawable.old,  R.drawable.old, //5
      R.drawable.old, R.drawable.old, R.drawable.old, R.drawable.old, R.drawable.old, //10
    };

static final String[] description = new String[] {
    "Variation of Sushis from fresh vegetables and seafoods! Good for family occassions!",
    "Oyakodon is a Japanese Rice Bowl dish with Chicken, Eggs and various sorts of healthy and delicious Veggetables!",
    "Japanese assorted Pancake that is made from many different ingredients. The taste is so delicious!",
    "Japanese Dumplings made of Rice Flour. This one of the healthiest sweets in Japan!",
    "Japanese assorted stews. Made from many different kind of veggetables. Popular in Winter!", //5
    "Stew made of Beef and Veggetables. Very delicious and delightful! Yummy!",
    "new era",
    "new era",
    "new era",
    "new era", //10
    };

private Integer[] difficultyid =  {

      R.drawable.medium, R.drawable.hard, R.drawable.medium, R.drawable.hard, R.drawable.hard, //10
    };

How do I code the NextActivity to show layouts based on item click? For example, if item 0 was clicked, setContentView(R.layout.item0), if item 1 was clicked, setContentView(R.layout.item1) and so on?

Answer 1

In MainActivity in the onListItemClick section:

Bundle bundle = new Bundle();
bundle.putint("Layout", position);

Intent newIntent = new Intent(this.getApplicationContext(), NextActivity.class);
newIntent.putExtras(bundle);
startActivityForResult(newIntent, 0);

and the second part is like sunny told:

Bundle bundle = this.getIntent().getExtras();
int chooser = bundle.getInt("Layout");

switch(chooser) {
case 0:
setContentView(R.layout.main0);
break;

case 1:
setContentView(R.layout.main1);
break;
......
......
} and so o

Answer 2

You can take a integer variable stored using sharedPreference and initially set to 0. change the value of integer on activity start and load the setContentView according to that variable.

http://developer.android.com/reference/android/content/SharedPreferences.html

http://developer.android.com/guide/topics/data/data-storage.html

for example

 int chooser;      // sharedPrefernce variable in your mainActivity 

//this is your activity for diiferent layouts

switch(chooser) {
case 0;
setContentView(R.layout.main0);
break;

case 1:
setContentView(R.layout.main1);
break;
......
......

} and so on............
