I have a listview and listview has some data,
I hope these data have different color
EX: if this is Lesson 1 color blue and Lesson 2 is color red.....
so,I use
but it can not change.
why?
this is my code:
public class Listening extends AppCompatActivity {
ArrayList<Listenlist> listenlists = new ArrayList<Listenlist>();
ListView listview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listening);
listview = (ListView) findViewById(R.id.list);
seraechsql2();
}
public void seraechsql2(){
View v =null;
String result = dblisten.executeQuery();
try{
TextView name = ((TextView) v.findViewById(R.id.name));
JSONArray jsonArray = new JSONArray(result);
length=jsonArray.length();
for(int i =0; i < jsonArray.length(); i++)
{
JSONObject jsonData = jsonArray.getJSONObject(i);
String les=jsonData.getString("lesson");
Listenlist team = new Listenlist("L"+les);
if(les==.....){//my condition
name.setTextColor(Color.BLACK);//I try to change it to black but fail
}
listenlists.add(team);
final ListenlistAdapter adapter = new ListenlistAdapter(this, R.layout.listenlist, listenlists);
listview.setAdapter(adapter);
listview.setTextFilterEnabled(true);
listview.setSelector(R.drawable.green);
}
}
catch(Exception e){}
}
}
thanks
if you use listview, you must create separate custom layout.simple_list_item_1 with your own customization and you would also need a class to control this layout (add data in it, create new elements etc). It is more complicated than RecyclerView.
Check more details here: https://www.simplifiedcoding.net/custom-listview-android/
I would suggest you to use RecyclerView to list display list of items. You can update based color based on the item position. refer this link - https://developer.android.com/guide/topics/ui/layout/recyclerview
