我有一个带有ImageView和TextView的自定义微调器,但是返回代码不返回这些值之一,而是将其作为对象返回。
如何分别获得可绘制的id或textview字符串而不是微调器的对象?
我是否必须在适配器,微调器本身或其他组件中尝试获取数据?

这是我的Spinner XML代码:
<?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="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="@+id/spinnerImage"
android:layout_width="40dp"
android:layout_height="40dp"
android:padding="5dp"
android:layout_weight="1"
android:src="@drawable/dark_red_square" /><!--Make sure image is present in Drawable folder-->
<TextView
android:id="@+id/spinnerText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_weight="2"
android:textSize="14sp"
android:gravity="center"
android:text="Demo"
android:textColor="#000" />
</LinearLayout>
此微调器处于片段状态。老实说,我不知道该在这里采样什么代码以供参考,但这是自定义适配器
public class CustomAdapter extends BaseAdapter {
Context context;
int flags[];
String[] countryNames;
LayoutInflater inflter;
public CustomAdapter(Context context, int[] flags, String[] countryNames, LayoutInflater inflter) {
this.context = context;
this.flags = flags;
this.countryNames = countryNames;
this.inflter = (LayoutInflater.from(context));
}
@Override
public int getCount() {
return flags.length;
}
@Override
public Object getItem(int position) {
return countryNames[position];
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = inflter.inflate(R.layout.spinner_item, null);
TextView spinnerText= convertView.findViewById(R.id.spinnerText);
ImageView spinnerImage = convertView.findViewById(R.id.spinnerImage);
spinnerText.setText(countryNames[position]);
spinnerImage.setImageResource(flags[position]);
return convertView;
}
}
