如何在android中的listview行中添加微调器？
我正在开发一个应用程序，我已使用listview解析器填充json。现在我必须在这个listview单行中添加本地微调器数组。
如何在此listview行中添加本地微调器数组。而且我想要选择listview的微调值。以下是我的代码，请建议我。

我创建了一个基本项目，向您展示如何设置一个简单的Spinner。这是列表行的xml：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center_vertical"
android:padding="20dp">
<TextView
android:id="@+id/row_item_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Spinner
android:id="@+id/row_item_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:padding="2dp" />
这是listview的适配器：
public class BasicSpinnerAdapter extends BaseAdapter {
private ArrayList<String> mSpinnerItems;
private ArrayList<String> mData;
private Context mContext;
public BasicSpinnerAdapter(ArrayList<String> data, ArrayList<String> spinnerItems, Context context) {
mData = data;
mContext = context;
mSpinnerItems = spinnerItems;
}
@Override
public int getCount() {
return mData.size();
}
@Override
public Object getItem(int position) {
return mData.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.row_item_spinner, null);
}
TextView textView = (TextView) view.findViewById(R.id.row_item_textview);
Spinner spinner = (Spinner) view.findViewById(R.id.row_item_spinner);
textView.setText(mData.get(position));
ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, mSpinnerItems);
spinner.setAdapter(adapter);
return view;
}
这是我的活动，我开始这一切：
public class SpinnerListviewActivity extends AppCompatActivity {
private ListView lvSpinner;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.spinner_listview_activity);
lvSpinner = (ListView) findViewById(R.id.listview_spinner);
ArrayList<String> mData = new ArrayList<>();
mData.add("Test1");
mData.add("Test2");
mData.add("Test3");
mData.add("Test4");
ArrayList<String> mSpinnerData = new ArrayList<>();
mSpinnerData.add("1");
mSpinnerData.add("2");
mSpinnerData.add("3");
mSpinnerData.add("4");
BasicSpinnerAdapter adapter = new BasicSpinnerAdapter(mData, mSpinnerData, this);
lvSpinner.setAdapter(adapter);
}
}
我的活动的xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="@+id/listview_spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
Listview的屏幕截图：
希望这能让您了解如何在List行中设置基本Spinner。随意提出任何问题！
