我的佈局中有兩個微調框。第一個選擇車輛，第二個從該特定車輛的短名單中選擇顏色。例如（選擇Bajaj，第二個需要顯示已保存的車輛顏色列表）多個自定義微調框始終將值設置爲一個spninner
在這裏，我確實從車輛和顏色的數據庫中獲取所有數據。這兩個價值都在我的手中。但是，如果我在Spinner1中選擇車輛類型，它將顯示同一個微調器中的車輛顏色，而不是顯示在Spinner2中。首先我有相同的（微調getset類，適配器類，自定義佈局）。現在我創建了所有三個不同的。即使現在也遇到同樣的問題。
如何找到，我在哪裏做錯了。以下是我正在使用的代碼。
public void setListData()// gets vehicles value from DB
{
List<VehicleGetSetter> contacts = vdb.getVehicleListToCustomer(vendor_id);
for (VehicleGetSetter cn : contacts) {
final BikeSpinner sched = new BikeSpinner();
sched.setBikeName("Select Bike");
CustomListBikeName.add(sched);
}}
private void setBikeAdapterValues() {// set Vehicle value in Spinner1
Resources res = getResources();
adapter = new BikeSpinnerAdapter(NewCustomer.this, R.layout.bike_spinner, CustomListBikeName,res);
mySpinner.setAdapter(adapter);
mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parentView, View v, int position, long id) {
bike_no_from_adapter = ((TextView) v.findViewById(R.id.textbike_numbr)).getText().toString();
what_bike = ((TextView) v.findViewById(R.id.textbike)).getText().toString();
String OutputMsg = "Selected : \n\n"+bike_no_from_adapter;
if(position!=0){
setListBikeColor(bike_no_from_adapter);
}
@Override
public void onNothingSelected(AdapterView<?> parentView) {
//Toast.makeText(getApplicationContext(), "You Must Select Vehicle", Toast.LENGTH_LONG).show();
}
});
}
public void setListBikeColor(String bike_no_from_adapter){// get color of selected vehicles from DB
List<VehicleGetSetter> contacts1 = vdb.getVehicleColorListToCustomer(vendor_id,bike_no_from_adapter);
for (VehicleGetSetter cn1 : contacts1) {
final BikeSpinn sched1 = new BikeSpinn();
sched1.setBikeNumber(cn1.getColor());
CustomListBikeColor.add(sched1);
setBikeAdapterValuesColor();
}
}
private void setBikeAdapterValuesColor() {// trying to set value in second spinner, but setting in same vehicle spinner.
Resources res2 = getResources();
coloradapter = new BikeSpinnerColor(NewCustomer.this, R.layout.bike_spinner_color, CustomListBikeColor,res2);
cust_bike_color.setAdapter(coloradapter);
cust_bike_color.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parentView, View v, int position, long id) {
// Get selected row data to show on screen
bike_no_from_adapter = ((TextView) v.findViewById(R.id.textbike_numbr)).getText().toString();
what_bike = ((TextView) v.findViewById(R.id.textbike)).getText().toString();
@Override
public void onNothingSelected(AdapterView<?> parentView) {
//Toast.makeText(getApplicationContext(), "You Must Select Vehicle", Toast.LENGTH_LONG).show();
}
});
}
MainLayout包含用於紡紗微調
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/bg_blue"
android:orientation="vertical"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/bike"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:textSize="22dp"
android:textColor="#000000"
android:text="Bike Details" />
<Spinner
android:id="@+id/cust_bike"
android:layout_width="120dp"

</LinearLayout>
自定義佈局（用於微調相似（名稱不同））
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:id="@+id/textbike"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18dp"
android:layout_marginRight="5dp"
android:textColor="#000000" />
<TextView
android:id="@+id/textbike_numbr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18dp"
android:textColor="#000000" />
</LinearLayout>
定製ArrayAdapterClass（有兩個紗廠兩個類似的類）
public class BikeSpinnerAdapter extends ArrayAdapter<String>{
private Activity activity;
private ArrayList data;
public Resources res;
BikeSpinner tempValues=null;
LayoutInflater inflater;
public BikeSpinnerAdapter(NewCustomer activitySpinner,
int textViewResourceId,
ArrayList objects,
Resources resLocal
)
{
super(activitySpinner, textViewResourceId, objects);
activity = activitySpinner;
data = objects;
res = resLocal;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getDropDownView(int position, View convertView,ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
public View getCustomView(int position, View convertView, ViewGroup parent) {
View row = inflater.inflate(R.layout.bike_spinner, parent, false);
tempValues = null;
tempValues = (BikeSpinner) data.get(position);
TextView label = (TextView)row.findViewById(R.id.textbike_numbr);
TextView sub = (TextView)row.findViewById(R.id.textbike);
label.setText(tempValues.getBikeName());
sub.setText(tempValues.getBikeNumber());
return row;
}
}
最終BikeSpinner SCHED =新BikeSpinner（）你的layout.xml在哪兒？ –
你如何獲得列表中的值？ –
感謝小小的陽光，vivek mishra。我添加了佈局。價值觀得到妥善處理。如果我從Spinner 1中選擇車輛，顏色會正確。但是，顏色（紅色）正在替換Spinner1的值，而不是加載到Spinner2中 –
