我正在做一个从API检索其项目的微调器，我检查了邮递员的结果，但是那里没有错误，而且我什至不能单击微调器，或者微调器只是没有下拉，这是代码，我检查了所有其他解决方案已经存在，但不是很像这样
Spinner xml：
<Spinner
android:id="@+id/select_plan_spinner"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:background="@drawable/sos_edit_bg"
android:gravity="center"
android:spinnerMode="dropdown"
android:textColor="@color/white_new"
android:visibility="visible"></Spinner>
微调框：
plan_spinner = (Spinner) findViewById(R.id.select_plan_spinner);
plan_spinner：
plan_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
plan_id = PLAN_ID.get(position);
Double price = PLAN_PRICE.get(position);
planprice = price;
Log.e("planprice", "planprice>>" + planprice);
if (plan_id != 0) {
int pos = position - 1;
String view_route = feeditem.get(pos).getIMEI();
if (view_route.equals("0")) {
view_route = "No";
} else {
view_route = "yes";
}
desc.setText("Description: " +
feeditem.get(pos).getMessage() + "\n View Route History: " + view_route);
} else {
desc.setText("Please select plan");
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
API：
