I'm using a ListView to display an array of names. Code for it looks like this:
public class Imenik extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final String[] seznam = getResources().getStringArray(R.array.seznam_array);
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, seznam));
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onI开发者_如何转开发temClick(AdapterView<?> parent, View view, int position, long id) {
if ("Baj And".equals(seznam[position]))
{ Intent i = new Intent(Imenik.this,Bajzelj.class); startActivity(i); lv.getItemIdAtPosition(position); }
else if ("Bes Jaz".equals(seznam[position]))
{ Intent i = new Intent(Imenik.this,Bajzelj.class); startActivity(i); }
}
});
}
}
Now I would like to display this names into just one view (Only one name per choice) with different data (one xml file).
public class Bajzelj extends Activity {
int position;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
this.setTitle("Interni imenik");
setContentView(R.layout.main);
final String[] seznam = getResources().getStringArray(R.array.seznam_array);
{
if ("Bajželj Andrej".equals(seznam[position]))
{
TextView ime = (TextView) findViewById(R.id.ime);
ime.setText("And Baj");
TextView telefon = (TextView) findViewById(R.id.telefon);
telefon.setText("Telefon: +386 1 476");
TextView gsm = (TextView) findViewById(R.id.mobitel);
gsm.setText("GSM: +386 41 ");
TextView skype = (TextView) findViewById(R.id.skype);
skype.setText("Skype: ba+");
TextView email = (TextView) findViewById(R.id.email);
email.setText("E-pošta: and.baj@som.org");
ImageView slika = (ImageView) findViewById(R.id.slika);
slika.setImageResource(R.drawable.andbaj);
}
else if ("Bes Jan".equals(seznam[position]))
{
TextView ime = (TextView) findViewById(R.id.ime);
ime.setText("Jan Bes");
TextView telefon = (TextView) findViewById(R.id.telefon);
telefon.setText("Telefon: +386 1 4");
TextView gsm = (TextView) findViewById(R.id.mobitel);
gsm.setText("GSM: +386 41 75");
TextView skype = (TextView) findViewById(R.id.skype);
skype.setText("Skype: sf");
TextView email = (TextView) findViewById(R.id.email);
email.setText("E-pošta: Jan.Besej.si");
ImageView slika = (ImageView) findViewById(R.id.slika);
slika.setImageResource(R.drawable.besjaz);
}
}
}
}
Is it possible to display them like this? I'm not a programmer so I'm having a lot of troubles with this one. I know that I should check for position somehow but I don't know how to do this?
Thanks in advance to anybody who is willing to help me.
follow this more effective way.
- Use a Map object to store individual user data.
- Add these map objects to the List.
- Use custom adapter to display in the ListView.
- Whenever user clicks on particular list item, pass its position in intent.
- get position from Bundle and retrieve the particular user data from map of List.
- display all the data of the user.
If you want a code snippet send me the user data fields i can send you the code snippet.
here is the code.

Then run and enjoy......!
The way in which you are passing the ID to the new activity is strange. Try using this:
Intent i = new Intent(Imenik.this,Bajzelj.class);
i.putExtra("id", id);
startActivity(i);
Then, once you're in your Bajzelj activity, get the id like this:
Bundle bundle = getIntent().getExtras();
long _id = bundle.getLong("id");
