In my app, I have a Spinner
, that can be filled with two Array
s of Strings
, stored in my values/strings.xml
resource. Depending on the state of two RadioButtons, the values from the correct Array is selected and my Spinner gets filled.
For each Array of Strings, I have an Array of Icons which have the same size. All of my icons start with an "A" and are followed by a number. I can't change this, it's stored like that in the database. I have an Array in Strings.xml with all the numbers I require to draw the icons. All the actual icons can be found in the drawable
resource folder.
Now I want to show the corresponding item next to the String from the list which was selected by the Spinner. When an item gets selected, I just need to see the text.
I have searched the Internet for a good tutorial, but with what I have found I have not succeeded in doing this. I'm just beginning in Android programming so I think I need a little help. I hope that somebody can guide me in the right direction.
I put my String Array within actual Arrays, such as:
// Arrays with each function in text
arbeiderjobs = getResources().getStringArray(R.array.arbeiders);
bediendejobs = getResources().getStringArray(R.array.bediende);
// Arrays with each function ID
arbeiderjobsid = getResources().getIntArray(R.array.arbeidersid);
bediendejobsid = getResources().getIntArray(R.array.bediendeid);
When one of the RadioButtons gets selected, I use the following event handler code:
// RadioButton 'Arbeider': If a value gets chosen in this list,
// the corresponding ID is put in the below variable
RadioButton rbArbeider = (RadioButton) findViewById(R.id.rbArbeider);
rbArbeider.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
if (isChecked)
{
showSpinner(arbeiderjobs, R.id.cmbFuncties);
s.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parentView,
View selectedItemView, int position, long id)
{
functie = arbeiderjobsid[position];
statuut = 1;
visible = false;
}
});
visible = true;
}
} // s.setOnItemSelectedListener
}); // rbArbeider.setOnCheckedChangeListener
This is my showSpinner
method:
private void showSpinner(String [] jobs, int id)
{
MyCustomAdapter adapter = new MyCustomAdapter
(
FindJob.this,
R.layout.spinnerrow,
jobs
);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
for (int i = 0; i < jobs.length; i++)
{
adapter.add(jobs[i]);
}
Spinner s = (Spinner) findViewById(id);
s.setClickable(true);
s.setAdapter(adapter);
}
I've made a custom adapter based on this tutorial, but I'm kind of tangled in it... I need some help:
public class MyCustomAdapter extends ArrayAdapter<String>
{
public MyCustomAdapter(Context context, int textViewResourceId,
String[] objects)
{
super(context, textViewResourceId, objects);
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{
return getCustomView(position, convertView, parent,
arbeiderjobs, arbeiderjobsid);
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
return getCustomView(position, convertView, parent,
arbeiderjobs, arbeiderjobsid);
}
public View getCustomView(int position, View convertView, ViewGroup parent,
String jobs[], int jobsid[])
{
// return super.getView(position, convertView, parent);
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.spinnerrow, parent, false);
TextView label = (TextView) findViewById(R.id.functie);
label.setText(jobs[position]);
ImageView icon = (ImageView) row.findViewById(R.id.icon);
String uri = "@drawable/a" + jobsid[position];
int imageResource = getResources().getIdentifier
(
uri,
null,
getPackageName()
);
icon.setImageResource(imageResource);
if (visible)
{
icon.setVisibility(View.GONE);
}
return row;
}
}
This is what I would want it to look like:
