我正在开发Android应用程序中，我有3个纺纱从一个叫 部，实践数据库填充和地址无法根据从数据库
我有条件地加载它们即检索的值设置微调位置，如果它是部门A负载实践A，B并根据实践设置地址。
然后，我通过getSelectedItemPosition（）将这些位置保存在另一个数据库表中。
现在，当我尝试他们3变量deptpos，practipos和addrpos。 但是，当我初始化纺纱它显示了他们的部门剩下的只有正确的位置后，使用为setSelection不工作:(
这里是我的代码
//Initializing the shared preferences variable
final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
//Loading the database in writable format
db=mydbhelper.getWritableDatabase();
//For Medicines Table
try{
//For medicines
Cursor medspin = db.query("medicines", null,"_id="+prefs.getInt("pos",1),null,null,null,null);
medspin.moveToFirst();
//Filling the variables to set selemedspintion
deptpos=medspin.getInt(medspin.getColumnIndex("provider_department"));
practipos=medspin.getInt(medspin.getColumnIndex("provider_practice"));
addrpos=medspin.getInt(medspin.getColumnIndex("provider_address"));
hsname=medspin.getString(medspin.getColumnIndex("healthsystem"));
medspin.close();
Toast td=Toast.makeText(this,"Loaded dept is "+deptpos+"Loaded Provider is "+practipos+"Address is "+addrpos,Toast.LENGTH_LONG);
td.show();
}
catch(Exception e){
Log.e("Error","Error",e);
}
try{
//Cursor
Cursor depcur = db.rawQuery("SELECT _id,department,"+prefs.getString("hsname",null)+ " FROM dept_masterdata WHERE "+prefs.getString("hsname",null)+"=1",null);
depcur.moveToFirst();
startManagingCursor(depcur);
String[] from = new String[]{"department"};
int[] to = new int[] { android.R.id.text1 };
// Now creating an array adapter and set it to display using my row
//Adaptor for Department
SimpleCursorAdapter deptype =new SimpleCursorAdapter(this,android.R.layout.simple_spinner_item, depcur, from, to);
deptype.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dep.setAdapter(deptype);
}
catch(Exception e){
Log.e("Error","Error",e);
}
//Now determine which department is selected
//Department
dep.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent,View view,int pos,long id){
deptid=dep.getSelectedItemId();
//Setting the practice spinner based on the department selected
Cursor pracur = db.rawQuery("SELECT _id,practice,dept_link,hs_id FROM practice_masterdata WHERE dept_link="+deptid+" AND hs_id="+(prefs.getInt("hsid",0)),null);
pracur.moveToFirst();
startManagingCursor(pracur);
String[] from1 = new String[]{"practice"};
int[] to1 = new int[]{android.R.id.text1};
SimpleCursorAdapter practype =new SimpleCursorAdapter(view.getContext(),android.R.layout.simple_spinner_item, pracur, from1, to1);
practype.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
pra.setAdapter(practype);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
//Practice
pra.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent,View view,int pos,long id){
practid=pra.getSelectedItemId();
//Setting the address based on the practice selected
Cursor addcur =db.rawQuery("SELECT * FROM address_masterdata WHERE practice_link="+practid,null);
addcur.moveToFirst();
startManagingCursor(addcur);
String[] from2 = new String[]{"address"};
int[] to2 = new int[]{android.R.id.text1};
SimpleCursorAdapter addtype =new SimpleCursorAdapter(view.getContext(),android.R.layout.simple_spinner_item,addcur, from2, to2);
addtype.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
add.setAdapter(addtype);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
//Address
add.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent,View view,int pos,long id){
addrid=add.getSelectedItemId();
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
//Setting the spinners based on the above variables
dep.setSelection(deptpos);
pra.setSelection(practipos);
add.setSelection(addrpos,false);
}
我如果变量是一个祝酒证实加载正确的值他们是但它根本不设置他们:(。奇怪的是部门正在显示正确的设置，而实践和地址都不是全部:(请指出我要去哪里错了
谢谢
