用Android Studio实现仿微信APP门户界面设计

windows操作系统、Android Studio

注意layout_height不能设置为match_parent，否则bottom无法显示

这里只给出了第一个垂直LinearLayout-聊天菜单，其余三个与之类似，注意修改id。

这里也只给出了第一个分段

package com.example.project1;

import android.os.Bundle;

import androidx.fragment.app.Fragment;

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


public class weixin_liaotian extends Fragment {



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


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

这里也只给出聊天分段的文件

这个文件实现了Fragment的切换、底部的click事件以及图标、文字的颜色切换

除此之外，还有drawable文件夹中的图标文件和value文件夹中的colors文件，具体代码可以在代码仓库查到。

在本次实验中，通过编辑bottom.xml和top.xml文件完成了底部和顶部的实现，通过编辑Fragment文件实现了中间界面的展示和隐藏，在MainActivity.java中实现了大部分功能，在阿里矢量库找到了需要的图标。实验中产生了许多问题，通过查阅其他人的博客解决了问题。
