                android:visibility="gone" />
        </RelativeLayout>
    </LinearLayout>
</RelativeLayout>

02.创建PopupWindow：

    if (null == cameraControlPopWindow)
    {
        val view = layoutInflater.inflate(R.layout.base_dialog_item_large, null)
        view.line1.visibility = if (confType == ConfType.LOCAL_PTOP) View.GONE else View.VISIBLE
        view.layout2.visibility = if (confType == ConfType.LOCAL_PTOP) View.GONE else View.VISIBLE
        view.tv1.text = "本地会场"
        view.tv2.text = "对方会场"
        view.layout1.setOnClickListener {
           //TODO 点击事件
        }
        view.layout2.setOnClickListener {
          //TODO 点击事件
        }
        cameraControlPopWindow = PopupWindow(
            view,
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT,
            true
        )
        //解决6.0以下系统点击外部不会自动消失的问题
        cameraControlPopWindow!!.setBackgroundDrawable(getDrawable())
        cameraControlPopWindow!!.isOutsideTouchable = true
        cameraControlPopWindow!!.isFocusable = true
    }
    if (cameraControlPopWindow!!.isShowing)
    {
        cameraControlPopWindow!!.dismiss()
    } else
    {
        cameraControlPopWindow!!.showAsDropDown(cameraControlIcon, 0, 10, Gravity.BOTTOM)
    }

2.创建AlertDialog：

01.创建AlertDialog的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/layout1"
    android:gravity="center_horizontal"
    >
    <Button android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示带取消、中立和确定按钮的对话框"/>

    <Button android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示列表的对话框"/>

    <Button android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示带单选列表对话框"/>

    <Button android:id="@+id/button4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示带多选列表对话框"/>

</LinearLayout>

02.创建AlertDialog

class MainActivity : AppCompatActivity(), OnRefreshListener, OnRefreshLoadMoreListener,
    MainContract.View {

    //页码
    private var currentPage = 1

    //数据源
    private var mList = ArrayList<Data>()

    private lateinit var mJokeAdapter: NewsAdapter

    private var refreshLayout: SmartRefreshLayout? = null
    private var mJokeListView: RecyclerView? = null
    private lateinit var mPresenter: MainPresenter

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        refreshLayout = findViewById(R.id.refreshLayout)
        mJokeListView = findViewById(R.id.mJokeListView)
        mJokeAdapter = NewsAdapter()
        mPresenter = MainPresenter()
        initList()
        mPresenter.getData(0, 0)
    }

    override fun onStart() {
        super.onStart()
        mPresenter.takeView(this)
    }
    
    override fun refreshView(orientation: Int, data: List<Data>) {
        if (orientation == 0) {
            refreshLayout?.finishRefresh()
            //列表要清空
            mList.clear()
            mList.addAll(data)
            mJokeAdapter.submitList(mList)
            //适配器要全部刷新
            mJokeAdapter.notifyDataSetChanged()
        } else if (orientation == 1) {
            refreshLayout?.finishLoadMore()

            //上一次的最大值
            val positionStart = mList.size

            mList.addAll(data)
            //需要注意：submitList()方法不能传参数MutableList
            mJokeAdapter.submitList(mList)
            //局部刷新
            mJokeAdapter.notifyItemRangeInserted(positionStart, data.size)

        }
    }

    //初始化列表
    private fun initList() {

        //刷新组件
        refreshLayout?.setRefreshHeader(ClassicsHeader(this))
        refreshLayout?.setRefreshFooter(ClassicsFooter(this))

        //监听
        refreshLayout?.setOnRefreshListener(this)
        refreshLayout?.setOnRefreshLoadMoreListener(this)

        mJokeListView?.layoutManager = LinearLayoutManager(this)

        //设置适配器
        mJokeListView?.adapter = mJokeAdapter

    }

    override fun onRefresh(refreshLayout: RefreshLayout) {
        currentPage = 1
        mPresenter.getData(currentPage, 0)
    }

    override fun onLoadMore(refreshLayout: RefreshLayout) {
        currentPage += 1
        mPresenter.getData(currentPage, 1)
    }
}

3.创建列表对话框Dialog：

01.创建列表的适配器Adapter：

public class DialogListAdapter extends BaseAdapter {

    private List<HashMap<String,String>> mapList;
    private LayoutInflater inflater;
    private Context mContext;

    public DialogListAdapter(Context context, List<HashMap<String,String>>list){
        this.mContext = context;
        this.mapList = list;
        inflater = LayoutInflater.from(mContext);

    }

    @Override
    public int getCount() {
        return mapList.size();  //数据源的长度
    }

    @Override
    public Object getItem(int position) {
        return mapList.get(position); //返回数据源的其中某一个对象
    }

    @Override
    public long getItemId(int position) {
        return position; //返回adapter中的其中一个项的id
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        myViewHolder hv;
        if (null==convertView){
            hv = new myViewHolder();
            convertView = inflater.inflate(R.layout.adapter_dialog_view,null,false);
            hv.tvName = convertView.findViewById(R.id.tvName);
            hv.tvCountry = convertView.findViewById(R.id.tvCountry);
            hv.agree = convertView.findViewById(R.id.agree);
            hv.disAgree = convertView.findViewById(R.id.disAgree);
            convertView.setTag(hv);

        }else {
            hv = (myViewHolder)convertView.getTag();
        }
        //一定要判刑断下数据源是否为空，否则很大几率就crash了
        if (mapList!=null && !mapList.isEmpty()){
            hv.tvName.setText(mapList.get(position).get("name"));
            hv.tvCountry.setText(mapList.get(position).get("country"));
            //设置监听事件
            hv.agree.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(mContext, mapList.get(position).get("name"), Toast.LENGTH_SHORT).show();
                }
            });
            //设置监听事件
            hv.disAgree.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(mContext, mapList.get(position).get("country"), Toast.LENGTH_SHORT).show();
                }
            });
        }
        return convertView;
    }
liebiao
    class myViewHolder{
        TextView tvName;
        TextView tvCountry;
        Button agree;
        Button disAgree;
    }

}

02.创建列表Dialog：

public class MainActivity extends AppCompatActivity {

    private DialogListAdapter listAdapter;
    private List<HashMap<String, String>> lists = new ArrayList<>();
    String[] names = {"Tom", "jane", "kangkang", "mike"};
    String[] countries = {"china", "japan", "germany", "usa"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initViewDatas();
        findViewById(R.id.bt).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                show_adapter(v);
            }
        });

    }
    /**
     * 初始化adapter并填充数据
     */
    void initViewDatas() {
        listAdapter = new DialogListAdapter(this, lists);
        for (int i = 0; i < 10; i++) {
            HashMap<String, String> map = new HashMap<>();
            map.put("name", names[i % 4]);
            map.put("country", countries[i % 4]);
            lists.add(map);
        }
        listAdapter.notifyDataSetChanged();

    }

    //这是一个button的onclick事件
    public void show_adapter(View view) {

        AlertDialog.Builder adapterBuilder = new AlertDialog.Builder(this);
        adapterBuilder.setIcon(R.mipmap.ic_launcher_round);
        adapterBuilder.setTitle("This is Adapter Dialog");
        ListView listView = new ListView(this);

        adapterBuilder.setView(listView);
        listView.setAdapter(listAdapter);

        //设置适配器，设置监听事件，但是点击后会退出对话框
//        adapterBuilder.setAdapter(listAdapter, new DialogInterface.OnClickListener() {
//            @Override
//            public void onClick(DialogInterface dialog, int which) {
//                HashMap<String, String> selectMap = (HashMap<String, String>) listAdapter.getItem(which);
//                Toast.makeText(MainActivity.this, selectMap.get("name"), Toast.LENGTH_SHORT).show();
//            }
//        });

        adapterBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //do what you want
            }
        });

        adapterBuilder.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //do what you want
            }
        });
        adapterBuilder.show();
    }
}
