自定义popwindow的spinner下拉列表

自定义popwindow:

import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.PopupWindow;

import cn.firstleap.parent.R;
import cn.firstleap.parent.listener.IFLItemOnClickListener;

public class SpinerPopWindow extends PopupWindow {

    private Context mContext;
    private ListView mListView;
    private IFLItemOnClickListener mItemSelectListener;

    public ListView getListView() {
        return mListView;
    }

    public SpinerPopWindow(Context context) {
        super(context);
        mContext = context;
        init();
    }


    public void setItemListener(IFLItemOnClickListener listener) {
        mItemSelectListener = listener;
    }


    private void init() {
        View view = LayoutInflater.from(mContext).inflate(R.layout.popupwindow_spinner, null);
        setContentView(view);
        setWidth(LayoutParams.WRAP_CONTENT);
        setHeight(LayoutParams.WRAP_CONTENT);

        setFocusable(true);
        ColorDrawable dw = new ColorDrawable(0x00);
        setBackgroundDrawable(dw);


        mListView = (ListView) view.findViewById(R.id.mListView);
        mListView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView adapterView, View view, int position, long l) {
                dismiss();
                if (mItemSelectListener != null) {
                    mItemSelectListener.onClickListener(position);
                }
            }
        });
    }
}

布局：popupwindow_spinner

样式：shape_roundpopwindowspiner

适配器： SpinnerClassAdapter

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.textClass.setText(mData.get(position).getName());
        return convertView;
    }

    static class ViewHolder {
        TextView textClass;
    }
}

item布局：item_spinnerclass



    

实体类： 
  OrganizationlBean就省略了，换成需要的实体类就行了 
  
 
  
每个item点击回调接口：IFLItemOnClickListener 
public interface IFLItemOnClickListener {
    void onClickListener(int position);
}
 
  
在activity 中使用：
 
  
activity中布局：
 
  


            

            
        
 
  
 
  
 
  
声明：
 
  
private SpinnerClassAdapter mSpinnerClassAdapter;
    private List spinnerData = new ArrayList<>();
    private SpinerPopWindow mSpinerPopWindow;
 
  
初始化：
 
  
mSpinerPopWindow = new SpinerPopWindow(this);
        mSpinerPopWindow.getListView().setAdapter(mSpinnerClassAdapter);
 
  
mSpinerPopWindow.setItemListener(new IFLItemOnClickListener() {
            @Override
            public void onClickListener(int position) {
                loadStudent(spinnerData.get(position).getDep_id());
                textTitle.setText(spinnerData.get(position).getName());
            }
        });
 
  
展示下拉事件：
 
  
 case R.id.pullView://下拉
                LogUtils.i(TAG, "显示下拉popWindow");
                mSpinerPopWindow.setWidth(pullView.getWidth());
                mSpinerPopWindow.showAsDropDown(pullView);
                break;
 
  
加载本地数据或者异步加载网络数据：记得notify, textTitle显示选中的标题显示出来，这里是默认显示第一个数据
 
  
 spinnerData.addAll(JsonUtils.parseDataToList(data.toString(), OrganizationlBean.class));
                    mSpinnerClassAdapter.notifyDataSetChanged();
                    textTitle.setText(spinnerData.get(0).getName());
