Android: Looping through a string array - help needed on logic for intent method

Question

I'm a java novice and I've using the code below to display a list of clickable TextViews that call a specific class when they are clicked. It is a list of football team names. Eg. Arsenal Manchester United Chelsea Clicking on TextView Arsenal (TextView id = ars) will call ars.class Clicking on TextView Chelsea (TextView id = che)will call che.class I have over 20 football team names. I have an array of textview ids, which I loop through and assign them a clickable action. This works fine. I have an string array of teamnames, the code loops through the string array and assigns each teamname to a Class object, which is used in the Intent() method. When I run this code, the list is produced but when I click on a team name it always opens Wol.java, the last position in the string array. I need some help with the logic, so that when I click on Arsenal it opens ars.class Here is the code. ``` public final int[] teams = { R.id.ars, R.id.ast, R.id.bir, R.id.bla, R.id.blp, R.id.bol, R.id.che,…

Accepted Answer

`classname` is being overwritten every time you iterate in the foreach loop inside `setTeamNames()`. Thus, only the last classname remains at the end.

If `teams` and `teamnames` have the same number of entries (which they should), you can use the following code and get rid of `setTeamNames()` completely.

```
final String prefix = "ttj.android.ft.teams.";
for (int i = 0; i < teams.length; i++) {
    tv = (TextView) findViewById(teams[i]);
    tv.setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
       try {
          Class class = Class.forName(prefix + teamnames[i]);               
          Intent open = new Intent(Transfers.this, class);
          startActivity(open);
        } catch (ClassNotFoundException e) {
          e.printStackTrace();
        }
    });
}
;
```
