android 复选功能的spinner,Android - 当我们选中复选框时，Spinner需要更改

我有checkBox和Spinner。如果checkbox被选中，那么spinner应该调用数据库并从那里获取值，否则为默认值。Android - 当我们选中复选框时，Spinner需要更改

我的问题是： 如果CheckBox被选中，应该调用Spinner。如何实现这一点？

我的代码是：

private HashMap retrunTypes =new HashMap();

checkBox1=(CheckBox)findViewById(R.id.checkBox1);

checkBox1.setOnCheckedChangeListener(new OnCheckedChangeListener() {

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

if(isChecked) {

rtnStatus =true;

retrunTypes = getReturnRason();

}else {

rtnStatus =false;

}

}

});

微调：

retrunTypes = getReturnRason();

ArrayList returnTypeList = new ArrayList();

for (Map.Entry entry : retrunTypes.entrySet()) {

ReturnProduct myProduct = entry.getValue();

returnTypeList.add(myProduct.getDescription());

}

retuReason = (Spinner) findViewById(R.id.retuReason);

reTypeAdapter = new ArrayAdapter(SalesActivityGroup.group.getApplicationContext(),android.R.layout.simple_spinner_item, returnTypeList);

reTypeAdapter.setDropDownViewResource(android.R.layout.simple_spinner_item);

retuReason.setAdapter(reTypeAdapter);

retuReason.setOnItemSelectedListener(new OnItemSelectedListener() {

public void onItemSelected(AdapterView> parent, View view,int arg2, long arg3) {

//selectedReType = parent.getSelectedItem().toString();

selectedReTypeId= arg2;

selectedReType = retrunTypes.get(selectedReTypeId).getReturnReason();

//ReturnProduct rProduct = findReturnType(selectedReType);

processingRequird = retrunTypes.get(selectedReTypeId).getProcessingRequired();

selectedReTypeCode = selectedReType;

selectedRetCategory = retrunTypes.get(selectedReTypeId).getReturnCategory();

}

public void onNothingSelected(AdapterView> arg0) {

}

});

private HashMap getReturnRason(){

DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(this);

HashMap returnType = new HashMap();

try {

dbAdapter.openDataBase();

String query ="";

if(rtnStatus) {

query = "SELECT rs.ReturnReasonCode,rs.ReturnType,rs.Description,rt.ProcessingRequired,rt.ReturnCategory " +

" FROM WMReturnReason rs,WMReturnType rt" +

" WHERE rs.ReturnType =rt.ReturnType AND rs.BusinessUnit=? AND Status ='1' AND rt.ProcessingRequired ='1' ";

}else {

query = "SELECT rs.ReturnReasonCode,rs.ReturnType,rs.Description,rt.ProcessingRequired,rt.ReturnCategory " +

" FROM WMReturnReason rs,WMReturnType rt" +

" WHERE rs.ReturnType =rt.ReturnType AND rs.BusinessUnit=? AND Status ='1' ";

}

String[] d = new String[]{strBusinessUnit};

ArrayList> stringList = dbAdapter.selectRecordsFromDBList(query, d);

dbAdapter.close();

//System.out.println("===getReturnType=="+stringList.size());

if(stringList.size() > 0){

for (int i = 0; i < stringList.size(); i++) {

ArrayList> arrayList = (ArrayList>) stringList.get(i);

ArrayList> list = arrayList;

ReturnProduct returnProduct = new ReturnProduct();

returnProduct.setReturnReason((String) list.get(0));

returnProduct.setReturnType((String) list.get(1));

returnProduct.setDescription((String) list.get(2));

returnProduct.setProcessingRequired((String) list.get(3));

returnProduct.setReturnCategory((String) list.get(4));

returnType.put(i, returnProduct);

}

}

} catch (Exception e) {

e.printStackTrace();

}

return returnType;

}
