加
catspinner.setOnItemSelectedListener(new planonClickListener());
至
chooseCategory();
这是整个代码-
public class TemoActivity extends Activity {public Spinner catspinner,planspinner3,planspinner1,planspinner2;protected void onCreate(Bundle mbfSplash) { super.onCreate(mbfSplash); setContentView(R.layout.main);chooseCategory();choosePersonalPlan();chooseLargeBusPlan();chooseSmallMedPlan();}public void chooseCategory() { catspinner = (Spinner) findViewById(R.id.catspinner); ArrayAdapter<CharSequence> catAdapter = ArrayAdapter.createFromResource(this, R.array.ducategory, android.R.layout.simple_spinner_item); catAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); catspinner.setAdapter(catAdapter); catspinner.setonItemSelectedListener(new planonClickListener());}private void choosePersonalPlan(){ planspinner1 = (Spinner) findViewById(R.id.planspinner); List<String> planlist = new ArrayList<String>(); planlist.add("Elite Regular Plan"); planlist.add("Elite Super Plans"); planlist.add("Emirati Plan"); planlist.add("Pay As You Go"); planlist.add("Visitor Mobile Line"); ArrayAdapter<String> planAdapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, planlist); planAdapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); planspinner1.setAdapter(planAdapter1);}private void chooseLargeBusPlan(){ planspinner2 = (Spinner) findViewById(R.id.planspinner); List<String> planlist1 = new ArrayList<String>(); planlist1.add("Premier Plan"); planlist1.add("The Executive Plan"); planlist1.add("Business Circle Plan"); planlist1.add("Business Diamond Plan"); ArrayAdapter<String> planAdapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, planlist1); planAdapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); planspinner2.setAdapter(planAdapter2);}private void chooseSmallMedPlan(){ planspinner2 = (Spinner) findViewById(R.id.planspinner); List<String> planlist2 = new ArrayList<String>(); planlist2.add("Business Super Plan"); planlist2.add("Her Business Super Plan"); planlist2.add("Business Circle Plan"); planlist2.add("Pay As you Go® Plus"); ArrayAdapter<String> planAdapter3 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, planlist2);planAdapter3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);planspinner2.setAdapter(planAdapter3);}public class planonClickListener implements onItemSelectedListener { @Override public void onItemSelected(AdapterView<?> parent, View v, int pos, long id) { parent.getItemAtPosition(pos); if (pos==0){ choosePersonalPlan(); }else if (pos==1){ chooseLargeBusPlan(); } else if (pos==2){ chooseSmallMedPlan(); } } @Override public void onNothingSelected(AdapterView<?> arg0) { // TODO Auto-generated method stub } }}
