一、需要的工具

android Studio

微信界面所需的八张图标（绿色和灰色）将它们插入到drawable中去
这里采用的是AS里的矢量图片

二、类微信界面的功能

1.制作的可展示出四个可切换界面：微信、朋友、通讯录、设置；
2.界面中间显示内容，内容随下方栏的选择而切换，下方栏可点击切换，点击过的界面的图标为绿色，没有点击的界面的图标为灰色；如下图：

三、顶部布局layout

在res文件夹的layout中新建layout.xml，将标题栏的内容居中，并将背景色调为黑色，文字调为白色

<?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="65dp"
    android:gravity="center"
    android:background="#000000"
    android:orientation="vertical">

<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="MyWechat"
android:textColor="#ffffff"
android:textSize="20sp" />
    </LinearLayout>

四、底部布局bottom

1.在res文件夹的layout中新建bottom.xml，拖入TextView拖入ImageButton后会调用drawable，选取所需的图标；
2.复制粘贴四个并调整水平平铺布局。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:background="@color/black"
    android:baselineAligned="false"
    android:orientation="horizontal">

    <LinearLayout
        android:id="@+id/id_tab_weixin"

            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:clickable="false"
            android:gravity="center"
            android:text="朋友"
            android:textColor="#ffffff"
            android:textSize="15sp" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/id_tab_contact"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/id_tab_contact_img"
            android:layout_width="match_parent"
            android:layout_height="80dp"
            android:background="@color/black"
            android:clickable="false"
            android:contentDescription="@string/app_name"
            app:srcCompat="@drawable/contact_2" />

        <TextView

            android:textColor="#ffffff"
            android:textSize="15sp" />

    </LinearLayout>

    <LinearLayout

            android:textColor="#ffffff"
            android:textSize="15sp" />
    </LinearLayout>
</LinearLayout>

五、四个中间布局tab

新建四个tab.xml四个tab.xml分别对应四个界面的中间内容。
tab01.xml

<?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:gravity="center"
android:orientation="horizontal">

<TextView
    android:id="@+id/textView5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:gravity="center"
    android:layout_weight="1"
    android:text="这是微信聊天界面"
    android:textSize="25sp" />
</LinearLayout>

tab02.xml

<?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:gravity="center"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:layout_weight="1"
        android:text="这是朋友界面"
        android:textSize="25sp" />
</LinearLayout>

tab03.xml

<?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:gravity="center"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:layout_weight="1"
        android:text="这是通讯录界面"
        android:textSize="25sp" />
</LinearLayout>

tab04.xml

<?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:gravity="center"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:layout_weight="1"
        android:text="这是设置界面"
        android:textSize="25sp" />
</LinearLayout>

tab01.xml编辑好后界面如下

六、activity_main.xml

activity_main.xml里需要加上FrameLayout(重叠布局)和include

<?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">

<include layout="@layout/layout" />

<FrameLayout
    android:id="@+id/id_content"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1">

</FrameLayout>

<include layout="@layout/bottom" />
</LinearLayout>

七、MainActivity.java

package com.example.mywork;

import androidx.appcompat.app.AppCompatActivity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.widget.ImageButton;
import android.widget.LinearLayout;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    private LinearLayout mTabweixin;
    private LinearLayout mTabfrd;
    private LinearLayout mTabcontact;
    private LinearLayout mTabsetting;

    private ImageButton mImgWeixin;
    private ImageButton mImgFrd;
    private ImageButton mImgcontact;
    private ImageButton mImgSettings;

    private Fragment mTab05;
    private Fragment mTab01 = new weixinFragment();
    private Fragment mTab02 = new frdFragment();
    private Fragment mTab03 = new contactFragment();
    private Fragment mTab04 = new settingsFragment();

    private FragmentManager fm;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);

        initView();
        initEvent();
        initFragment();
        selectfragment(0);
    }


    private void initFragment(){
        //fragment的切换
        fm = getFragmentManager();
        FragmentTransaction transaction = fm.beginTransaction();
        transaction.add(R.id.id_content,mTab01);
        transaction.add(R.id.id_content,mTab02);
        transaction.add(R.id.id_content,mTab03);
        transaction.add(R.id.id_content,mTab04);
        transaction.commit();
    }

    private void initEvent(){
        mTabweixin.setOnClickListener(this);
        mTabfrd.setOnClickListener(this);
        mTabcontact.setOnClickListener(this);
        mTabsetting.setOnClickListener(this);
    }

    private void initView() {
        //改变图标的颜色
        mTabweixin = (LinearLayout)findViewById(R.id.id_tab_weixin);
        mTabfrd = (LinearLayout)findViewById(R.id.id_tab_frd);
        mTabcontact = (LinearLayout)findViewById(R.id.id_tab_contact);
        mTabsetting = (LinearLayout)findViewById(R.id.id_tab_settings);

        mImgWeixin = (ImageButton)findViewById(R.id.id_tab_weixin_img);
        mImgFrd = (ImageButton) findViewById(R.id.id_tab_frd_img);
        mImgcontact = (ImageButton)findViewById(R.id.id_tab_contact_img);
        mImgSettings = (ImageButton)findViewById(R.id.id_tab_settings_img);
    }

    private void selectfragment(int i){
        //显示选中界面的内容，选中界面图标为绿色
        FragmentTransaction transaction = fm.beginTransaction();
        hideFragment(transaction);
        switch (i){
            case 0:
                Log.d("setSelect","1");
                transaction.show(mTab01);
                mImgWeixin.setImageResource(R.drawable.chat_2);
                break;
            case 1:
                transaction.show(mTab02);
                mImgFrd.setImageResource(R.drawable.friend_2);
                break;
            case 2:
                transaction.show(mTab03);
                mImgcontact.setImageResource(R.drawable.contact_1);
                break;
            case 3:
                transaction.show(mTab04);
                mImgSettings.setImageResource(R.drawable.setting_1);
                break;
            default:
                break;
        }
        transaction.commit();
    }

    private void hideFragment(FragmentTransaction transaction) {
        //把没有使用的界面的内容隐藏
        transaction.hide(mTab01);
        transaction.hide(mTab02);
        transaction.hide(mTab03);
        transaction.hide(mTab04);
    }

    @Override
    public void onClick(View view) {
        //监听函数，监听到底是哪一个图标被击中从而显示哪一个界面的内容
        resetimg();
        switch (view.getId()){
            case R.id.id_tab_weixin:
                selectfragment(0);
                break;
            case R.id.id_tab_frd:
                selectfragment(1);
                break;
            case R.id.id_tab_contact:
                selectfragment(2);
                break;
            case R.id.id_tab_settings:
                selectfragment(3);
                break;
        }
    }

    public void resetimg(){
        //没有使用的界面的图标为灰色
        mImgWeixin.setImageResource(R.drawable.chat_1);
        mImgFrd.setImageResource(R.drawable.friend_1);
        mImgcontact.setImageResource(R.drawable.contact_2);
        mImgSettings.setImageResource(R.drawable.setting_2);
    }
}

八、四个Fragment

创建四个framgment的Java文件，用来调用界面。

1.weixinFragment

package com.example.mywork;

import android.os.Bundle;

import android.app.Fragment;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

/**
 * A simple {@link Fragment} subclass.
 * Use the {@link weixinFragment#newInstance} factory method to
 * create an instance of this fragment.
 */
public class weixinFragment extends Fragment {

    // TODO: Rename parameter arguments, choose names that match
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    // TODO: Rename and change types of parameters
    private String mParam1;
    private String mParam2;

    public weixinFragment() {
        // Required empty public constructor
    }

    /**
     * Use this factory method to create a new instance of
     * this fragment using the provided parameters.
     *
     * @param param1 Parameter 1.
     * @param param2 Parameter 2.
     * @return A new instance of fragment BlankFragment.
     */
    // TODO: Rename and change types and number of parameters
    public static weixinFragment newInstance(String param1, String param2) {
        weixinFragment fragment = new weixinFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.tab01, container, false);
    }
}

2.frdFragment

package com.example.mywork;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.app.Fragment;

/**
 * A simple {@link Fragment} subclass.
 * Use the {@link frdFragment#newInstance} factory method to
 * create an instance of this fragment.
 */
public class frdFragment extends Fragment {

    // TODO: Rename parameter arguments, choose names that match
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    // TODO: Rename and change types of parameters
    private String mParam1;
    private String mParam2;

    public frdFragment() {
        // Required empty public constructor
    }

    /**
     * Use this factory method to create a new instance of
     * this fragment using the provided parameters.
     *
     * @param param1 Parameter 1.
     * @param param2 Parameter 2.
     * @return A new instance of fragment BlankFragment.
     */
    // TODO: Rename and change types and number of parameters
    public static frdFragment newInstance(String param1, String param2) {
        frdFragment fragment = new frdFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.tab02, container, false);
    }
}

3.contactFragment

package com.example.mywork;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.app.Fragment;

/**
 * A simple {@link Fragment} subclass.

     * @return A new instance of fragment BlankFragment.
     */
    // TODO: Rename and change types and number of parameters
    public static contactFragment newInstance(String param1, String param2) {
        contactFragment fragment = new contactFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.tab03, container, false);
    }
}

4.settingsFragment

package com.example.mywork;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
