微信简单界面

• 一.top和bottom
• • 1.top
  • 2.bottom
• 二.创建四个Fragment，分别对应“聊天”、“联系人”、“朋友圈”、“我的”这四个xml文件
• 三.最后效果图：
• 四.我的gitee库: [https://gitee.com/jiang-zhongwen/jiang-zhongwen](https://gitee.com/jiang-zhongwen/jiang-zhongwen/).

需要一个linearlayout和一个text View

需要的控件以及呈现效果如下图所示：

这里给出一个LineaLayout示例代码：

其中wexinFragment函数如下：

package com.example.wechat;

import android.os.Bundle;

import androidx.fragment.app.Fragment;

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


public class wexinFragment extends Fragment {


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

各个java文件及Fragment文件如下：

以下是mainactivity函数，具体的函数定义见最后面的链接

public class MainActivity extends AppCompatActivity  {
    private Fragment wexinFragment=new wexinFragment();
    private Fragment myFragment=new myFragment();
    private Fragment worldFragment=new worldFragment();
    private Fragment friendFragment=new friendFragment();
    private FragmentManager fm;
    private LinearLayout linearLayout1,linearLayout2,linearLayout3,linearLayout4;
    private TextView textView1,textView2,textView3,textView4;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
        linearLayout1 = findViewById(R.id.LinearLayout_wexin);
        linearLayout2 = findViewById(R.id.LinearLayout_friend);
        linearLayout3 = findViewById(R.id.LinearLayout_world);
        linearLayout4 = findViewById(R.id.LinearLayout_my);
        linearLayout1.setOnClickListener(this::onClick);
        linearLayout2.setOnClickListener(this::onClick);
        linearLayout3.setOnClickListener(this::onClick);
        linearLayout4.setOnClickListener(this::onClick);
        initFragment();
        showfragment(0);
    }
