DialogFragment

	DialogFragment继承DialogFragment底层继承Fragment
自带Dialog对话框 重写Oncreateview方法添加子布局通过show（）方法展示
   Dialog dialog = new Dialog();
//最主要是这个方法 第一个参数为FragmentManager对象 第二个为自己起的名字
  dialog.show(getActivity().getSupportFragmentManager(),"wowo");

package com.example.day12work.ListFragment;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.day12work.R;

public class Dialog extends DialogFragment {


    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        View inflate = inflater.inflate(R.layout.kong, container, false);
        return inflate;
    }


}
