android 仿微信demo——微信主界面实现

目录主界面实现测试总结

以往文章中实现微信启动页,登录注册功能,此基础上继续完善仿微信功能。

主界面实现

(1)整体采用RelativeLayout相对布局

(2)最上面是toolbar操作栏,搜索框SearchView,Overflow(含有4个单选菜单项)

(3)中间使用Fragment组件(不使用ViewPager,有兴趣可以自己添加实现下)。

(4)最下面是水平的LinearLayout线性布局:含有4个自定义的控件

android 仿微信demo——微信主界面实现

这一篇主要是实现主界面,其他像顶部(toolbar,SearchView,Overflow),中间的fragment,后续文章在更新。

创建主界面activity MainWeixin.java

MainWeixin.java

package com.example.wxchatdemo;import android.annotation.SuppressLint;import android.app.AlertDialog;import android.app.Dialog;import android.app.FragmentManager;import android.app.FragmentTransaction;import android.content.DialogInterface;import android.content.Intent;import android.graphics.Color;import android.os.Bundle;import android.support.v4.app.FragmentActivity;import android.view.KeyEvent;import android.view.View;import android.view.Window;import android.widget.ImageView;import android.widget.TextView;public class MainWeixin extends FragmentActivity implements View.OnClickListener { private WeixinFragment firstFragment = null;// 用于显示微信界面 private ContactListFragment secondFragment = null;// 用于显示通讯录界面 private FindFragment thirdFragment = null;// 用于显示发现界面 private SelfFragment fourthFragment = null;// 用于显示我界面 private View firstLayout = null;// 微信显示布局 private View secondLayout = null;// 通讯录显示布局 private View thirdLayout = null;// 发现显示布局 private View fourthLayout = null;// 我显示布局 /*声明组件变量*/ private ImageView weixinImg = null;

} /** * 在这里面获取到每个需要用到的控件的实例,并给它们设置好必要的点击事件 */ @SuppressLint('NewApi') public void initViews() {fragmentManager = getFragmentManager();firstLayout = findViewById(R.id.weixin_layout);secondLayout = findViewById(R.id.contacts_layout);thirdLayout = findViewById(R.id.find_layout);fourthLayout = findViewById(R.id.self_layout);weixinImg = (ImageView) findViewById(R.id.weixin_img);contactImg = (ImageView) findViewById(R.id.contact_img);findImg = (ImageView) findViewById(R.id.find_img);selfImg = (ImageView) findViewById(R.id.self_img);weixinText = (TextView) findViewById(R.id.weixin_text);contactText = (TextView) findViewById(R.id.contact_text);findText = (TextView) findViewById(R.id.find_text);selfText = (TextView) findViewById(R.id.self_text);//处理点击事件firstLayout.setOnClickListener(this);secondLayout.setOnClickListener(this);thirdLayout.setOnClickListener(this);fourthLayout.setOnClickListener(this);

}}

创建主界面activity MainWeixin.java对应的主布局文件main_weixin.xml

main_weixin.xml

<RelativeLayout xmlns:android='http://schemas.android.com/apk/res/android' android:layout_width='match_parent' android:layout_height='match_parent'> <FrameLayoutandroid: android:layout_width='match_parent'android:layout_height='match_parent'android:background='@color/white'> </FrameLayout> <LinearLayoutandroid:layout_width='match_parent'android:layout_height='48dp'android:layout_alignParentStart='true'android:layout_alignParentLeft='true'android:layout_alignParentBottom='true'android:background='#f7f7f7'android:gravity='center'android:orientation='horizontal'><LinearLayout android: android:layout_width='0dp' android:layout_height='match_parent' android:layout_centerVertical='true' android:layout_weight='1' android:orientation='vertical' android:padding='3dp'> <ImageViewandroid: android:layout_width='wrap_content'android:layout_height='24dp'android:layout_gravity='center_horizontal'android:src='https://www.haobala.com/bcjs/@drawable/tab_weixin_pressed' /> <TextViewandroid: android:layout_width='wrap_content'android:layout_height='20dp'android:layout_gravity='center_horizontal'android:gravity='top'android:text='微信'android:textColor='#82858b'android:textSize='13dp' /></LinearLayout><LinearLayout android: android:layout_width='0dp' android:layout_height='match_parent' android:layout_centerVertical='true' android:layout_weight='1' android:orientation='vertical' android:padding='3dp'> <ImageViewandroid: android:layout_width='wrap_content'android:layout_height='24dp'android:layout_gravity='center_horizontal'android:src='https://www.haobala.com/bcjs/@drawable/tab_address_normal' /> <TextViewandroid: android:layout_width='wrap_content'android:layout_height='20dp'android:layout_gravity='center_horizontal'android:gravity='top'android:text='通讯录'android:textColor='#82858b'android:textSize='13dp' /></LinearLayout><LinearLayout android: android:layout_width='0dp' android:layout_height='match_parent' android:layout_centerVertical='true' android:layout_weight='1' android:orientation='vertical' android:padding='3dp'> <ImageViewandroid: android:layout_width='wrap_content'android:layout_height='24dp'android:layout_gravity='center_horizontal'android:src='https://www.haobala.com/bcjs/@drawable/tab_find_frd_normal' /> <TextViewandroid: android:layout_width='wrap_content'android:layout_height='20dp'android:layout_gravity='center_horizontal'android:gravity='top'android:text='发现'android:textColor='#82858b'android:textSize='13dp' /></LinearLayout><LinearLayout android: android:layout_width='0dp' android:layout_height='match_parent' android:layout_centerVertical='true' android:layout_weight='1' android:orientation='vertical' android:padding='3dp'> <ImageViewandroid: android:layout_width='wrap_content'android:layout_height='24dp'android:layout_gravity='center_horizontal'android:src='https://www.haobala.com/bcjs/@drawable/tab_settings_normal' /> <TextViewandroid: android:layout_width='wrap_content'android:layout_height='20dp'android:layout_gravity='center_horizontal'android:gravity='top'android:text='我'android:textColor='#82858b'android:textSize='13dp' /></LinearLayout> </LinearLayout></RelativeLayout>

创建4个Fragment.class和4个Fragment.xml布局,对应微信,通讯录,发现,我

WeixinFragment.java

package com.example.wxchatdemo;import android.annotation.SuppressLint;import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;@SuppressLint('ValidFragment')public class WeixinFragment extends Fragment { private String number; @SuppressLint('ValidFragment') WeixinFragment(String number) {this.number = number; } public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.weixin_fragment, container, false);return view; }}

ContactListFragment.java

package com.example.wxchatdemo;import android.annotation.SuppressLint;import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;@SuppressLint('ValidFragment')public class ContactListFragment extends Fragment { private String number; @SuppressLint('ValidFragment') ContactListFragment(String number) {this.number = number; } public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.weixin_fragment, container, false);return view; }}

FindFragment.java

package com.example.wxchatdemo;import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;public class FindFragment extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.find_fragment, container, false);return view; }}

SelfFragment.java

package com.example.wxchatdemo;import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;public class SelfFragment extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.self_fragment, container, false);return view; }}

创建四个fragmen布局,代码都一样,只要有就行,后面会完善的,四个fragment布局文件为,weixin_fragment.xml,contactlist_fragment.xml,find_fragment.xml,self_fragment.xml

<LinearLayout xmlns:android='http://schemas.android.com/apk/res/android' android:layout_width='match_parent' android:layout_height='match_parent'></LinearLayout>

在AndroidMainfest.xml中声明创建的activity,由于创建fragment不是activity,所有不用声明,声明主界面的activity即可(fragment是内嵌在activity中的)
