得到父类的私有属性

android.widget.ArrayAdapter类mObjects为私有属性：private List<T> mObjects;若要获取这个属性：可以在子类中定义一个属性，把这个属性赋值给mObjects，

代码如下：
getObjects()就会获取父类的私有属性

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.ozner.WaterPurifier.WaterPurifierManager;
import com.ozner.cup.CupManager;
import com.ozner.tap.TapManager;

import net.ozner.oznerproject.Command.DeviceData;
import net.ozner.oznerproject.R;

import java.util.ArrayList;
import java.util.List;

public class SlideAdapter extends ArrayAdapter<DeviceData> {

    static SlideAdapter instance;
    private List<DeviceData> slideBeans;
    public List<View> myViewGroup = new ArrayList<View>();
    public View lastview;
    public final String[] constate = new String[]{"未连接", "正在连接", "已连接"};

    public SlideAdapter(Context context, List<DeviceData> deviceDatas) {
        super(context, R.layout.list_item_handle_left, R.id.title_text, deviceDatas);
        this.slideBeans = deviceDatas;
        instance = this;
    }

    public static SlideAdapter instance() {
        return instance;
    }

    /**
     * 拖动之后的列表
     *
     * @return
     */
    public List<DeviceData> getSortList() {
        ArrayList<DeviceData> list = new ArrayList<DeviceData>();
        int n = getCount();
        for (int i = 0; i < n; i++) {
            list.add(getItem(i));
        }
        return list;
    }

    /**
     * 拖动之后的列表
     *
     * @return
     */
    public List<DeviceData> getObjects() {
        return slideBeans;
    }

//......
