我正在開發Android應用程序中，我有3個紡紗從一個叫 部，實踐數據庫填充和地址無法根據從數據庫
我有條件地加載它們即檢索的值設置微調位置，如果它是部門A負載實踐A，B並根據實踐設置地址。
然後，我通過getSelectedItemPosition（）將這些位置保存在另一個數據庫表中。
現在，當我嘗試他們3變量deptpos，practipos和addrpos。 但是，當我初始化紡紗它顯示了他們的部門剩下的只有正確的位置後，使用爲setSelection不工作:(
這裏是我的代碼
//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);
}
我如果變量是一個祝酒證實加載正確的值他們是但它根本不設置他們:(。奇怪的是部門正在顯示正確的設置，而實踐和地址都不是全部:(請指出我要去哪裏錯了
謝謝
