我如何在android中的listview行中添加微調框？

我正在開發一個應用程序，我用json解析器填充listview。現在我必須在這個listview單行內添加本地微調陣列。如何在此listview行內添加本地微調器陣列。而且我想要獲得選定的微調值listview。以下是我的代碼請給我建議。我如何在android中的listview行中添加微調框？

您的ListView是否具有自定義適配器和行.xml？ –

代碼太多。請刪除不相關的代碼。 –

使用可擴展列表視圖。 –

我創建了一個基本的項目向您展示如何設置一個簡單的微調。這是我的列表行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" />

這是爲ListView適配器：

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; 
}

，這是我的活動，在那裏我開始這一切：

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); 
}

}

我的活動的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>

請給我建議，根據我的code.I ahave使用json解析器獲取數據在列表視圖中，在這我必須添加本地微調陣列。我該怎麼做呢？ – Rohi
