首先,我们创建布局文件

main的主体布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/drawerlayout"
    >
    <LinearLayout
        android:id="@+id/center"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:background="@android:color/holo_blue_light"
            android:layout_width="match_parent"
            android:layout_height="60dp"></android.support.v7.widget.Toolbar>
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="onClick"
            android:text="点击添加一个联系人"/>
        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerview"
            android:layout_width="match_parent"
            android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>

    </LinearLayout>

    <!--Fragment替換該位置-->
    <FrameLayout
        android:id="@+id/left_layout"
        android:layout_width="300dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"></FrameLayout>
</android.support.v4.widget.DrawerLayout>

这是dialog的布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/name_et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </EditText>

    <EditText
        android:id="@+id/phone_et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <EditText
        android:id="@+id/email_et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

这是fragment的布局文件

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/holo_blue_light"
    >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="抽屜中過的Fragment"/>

</FrameLayout>

这是item布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/display_name_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:text="TextView"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/phone_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:text="TextView"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/email_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:text="TextView"
        android:textSize="18sp" />

</LinearLayout>

这是BlankFragment的代码

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class BlankFragment extends Fragment {


    public BlankFragment() {
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_blank, container, false);
    }

}

这是MyPhoneAdapter的主体

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;

/**

public class MyPhoneAdapter extends RecyclerView.Adapter<MyPhoneAdapter.ViewHolder> {
    private ArrayList<PersonInfo> mList;
    private Context mContext;
    private RecyclerView mRecyclerView;
    private LayoutInflater mInflater;

    public MyPhoneAdapter(ArrayList<PersonInfo> list, Context context, RecyclerView recyclerView) {
        mList = list;
        mContext = context;
        mRecyclerView = recyclerView;

    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    }
    public void setOnItemClickListener(OnItemClickListener mListener){

    }

    class ViewHolder extends RecyclerView.ViewHolder{
        TextView display_name_tv;
        TextView phone_tv;
        TextView email_tv;

        public ViewHolder(View itemView) {

            email_tv = (TextView) itemView.findViewById(R.id.email_tv);
        }
    }
}

这是PersonInfo的主体

public class PersonInfo {
    private String rawId;

    private String display_name;
    private String phone;
    private String email;

    public PersonInfo(String rawId, String display_name, String phone, String email) {

        this.email = email;
    }


    public PersonInfo() {
    }

    public String getRawId() {
        return rawId;
    }

    public void setRawId(String rawId) {
        this.rawId = rawId;
    }

    public String getDisplay_name() {
        return display_name;
    }

    public void setDisplay_name(String display_name) {
        this.display_name = display_name;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }


    @Override
    public String toString() {
        return "PersonInfo{" +
                "rawId='" + rawId + '\'' +
                ", display_name='" + display_name + '\'' +
                ", phone='" + phone + '\'' +
                ", email='" + email + '\'' +
                '}';
    }
}

最后不要忘了添加依赖
