    <p>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.</p> <p>It is a list of football team names.</p> <p>Eg.</p> <p>Arsenal Manchester United Chelsea</p> <p>Clicking on TextView Arsenal (TextView id = ars) will call ars.class Clicking on TextView Chelsea (TextView id = che)will call che.class</p> <p>I have over 20 football team names.</p> <p>I have an array of textview ids, which I loop through and assign them a clickable action. This works fine.</p> <p>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.</p> <p>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. </p> <p>I need some help with the logic, so that when I click on Arsenal it opens ars.class</p> <p>Here is the code.</p> <pre><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, R.id.eve, R.id.ful, R.id.hul, R.id.lee, R.id.liv, R.id.mid, R.id.mnc, R.id.mnu, R.id.nor, R.id.nwu, R.id.por, R.id.qpr, R.id.sto, R.id.sun, R.id.swa, R.id.tot, R.id.wes, R.id.wig, R.id.wol }; //String array of teamnames, named to correspond their class name. public final String[] teamnames = { "ars", "ast", "bir", "bla", "blp", "bol", "che", "eve", "ful", "hul", "lee", "liv", "mid", "mnc", "mnu", "nor", "nwu", "por", "qpr", "sto", "sun", "swa", "tot", "wes", "wig", "wol" }; TextView tv; Class classname; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.m_transfers); setTeamNames(); //Method sets up team names to a Class name. for (int i = 0; i &lt; teams.length; i++) { tv = (TextView) findViewById(teams[i]); tv.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent open = new Intent(Transfers.this, classname); startActivity(open); } }); } ; } public void setTeamNames() { for (String s : teamnames) { String name = "ttj.android.ft.teams." + s; try { classname = Class.forName(name); } catch (ClassNotFoundException e) { e.printStackTrace(); } } ; } </code></pre>

    1. COAre you seriously saying you've created 20 different Activities, one for each team? Why not just have one `Activity` (called `TeamActivity` for example) and pass the team name as a string `Extra` in the `Intent` you use for `startActivity(...)`?

    2. COVery new to android development, still getting my head around the Manifest. Yes, I have created 20 seperate activities in the manifest. Could I make a TeamActivity in the manifest?

    3. CO@tiptopjat You could make one TeamActivity in the manifest the same way you made the 20 different activities and then, as MisterSquonk said, just add a string or int to the Intent to differentiate.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
