Android实现第三方Mob短信验证登录以及手机号显示和修改用户名（简易新闻五）

关于之前的功能实现可以从制作简易新闻App导航篇中查看

因为这篇是写了有一段时间的博客，所以这篇（包括后面的简易新闻六）中关于手机号的传值用的是onActivityResult方法，以及intent.put。。方法，这样写是没有问题的，但是逻辑混乱，所以我在后面针对这一点做了优化，使用了全局变量方法存储，使用手机号这一关键值。如果，你打算一步一步来那也没关系，这样你会对这个app理解的更深入，或者你可以自己考虑一下使用全局变量来传值手机号码。如果你对全局变量用法还不是很明确，你可以参看以下博客：

Android实现存储和实时更新和取出全局变量
好了，讲了这么多先上一下最终效果：

本篇实现功能有：

1. 手机号短信验证登录，建立用户信息数据表
2. 侧滑栏头部显示用户名与手机号
3. 本地记住手机号，方便下次启动时不用重新登录

第一步，建议用户信息表user_info

设置表中id为自增长主键，user_phone外键先不用设置，因为相应功能将在以后实现

关于实现Android连接数据库请看连接数据库，实现下拉刷新（简易新闻三）

第二步，修改nav_header.xml文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="180dp"android:padding="10dp"android:orientation="horizontal"android:background="#80FFFF"><de.hdodenhof.circleimageview.CircleImageViewandroid:id="@+id/icon_image"android:layout_width="wrap_content"android:layout_height="wrap_content"android:src="@mipmap/mouse"android:layout_centerInParent="true"/><TextViewandroid:id="@+id/text_huoqu"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentBottom="true"android:textColor="@color/colorBlack"android:textSize="14sp"tools:ignore="HardcodedText" /><TextViewandroid:id="@+id/text_username"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_above="@id/text_huoqu"android:layout_marginBottom="9dp"android:layout_toEndOf="@+id/text_huoqu"android:text="个人博客地址：https://blog.csdn.net/Tobey_r1"android:textColor="@color/colorBlack"android:textSize="14sp"tools:ignore="HardcodedText"android:layout_toRightOf="@+id/text_huoqu" />
</RelativeLayout>

第三步，新建一个登录Activity活动LoginActivity.class与activity_main.xml

修改activity_main.xml布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="match_parent"tools:context=".UserMode.LoginActivity"><de.hdodenhof.circleimageview.CircleImageViewandroid:layout_width="wrap_content"android:id="@+id/imageLogo"android:layout_height="wrap_content"android:layout_alignParentTop="true"android:src="@mipmap/ic_launcher_foreground"android:layout_centerInParent="true"/>
//图片来源选择自己喜欢的图片放入即可<TextViewandroid:id="@+id/textview_login"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@+id/imageLogo"android:layout_marginTop="40dp"android:text="手机号快速登陆"android:textStyle="bold" /><EditTextandroid:id="@+id/login_input_phone_et"android:layout_width="280dp"android:layout_height="wrap_content"android:layout_below="@+id/textview_login"android:layout_marginTop="28dp"android:ems="10"android:hint="请输入手机号"android:inputType="phone" /><requestFocus /><EditTextandroid:id="@+id/login_input_code_et"android:layout_width="170dp"android:layout_height="wrap_content"android:layout_alignLeft="@+id/login_input_phone_et"android:layout_below="@+id/login_input_phone_et"android:layout_marginTop="30dp"android:hint="请输入验证码"android:inputType="textPassword"></EditText><Buttonandroid:id="@+id/login_request_code_btn"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignRight="@+id/login_input_phone_et"android:layout_alignTop="@+id/login_input_code_et"android:background="#01000000"android:text="获取验证码" /><Buttonandroid:id="@+id/login_commit_btn"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_alignLeft="@+id/login_input_code_et"android:layout_below="@+id/login_input_code_et"android:backgroundTint="@color/colorpink"android:textColor="@color/colorhuise"android:layout_marginTop="5dp"android:text="开始使用" /><Buttonandroid:id="@+id/btn_relogin"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@+id/login_input_code_et"android:layout_alignEnd="@+id/login_input_phone_et"android:layout_alignRight="@id/login_request_code_btn"android:layout_marginTop="65dp"android:layout_marginEnd="-88dp"android:layout_marginRight="-88dp"android:background="#01000000"android:text="手机号注册"android:textStyle="bold" /></RelativeLayout>

如果你是直接从这篇看的话，关于圆形图片的引用加入：

implementation 'de.hdodenhof:circleimageview:2.1.0'

第四步，修改colors.xml文件

在res/values/ 下修改colors.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources><color name="colorPrimary">#008577</color><color name="colorPrimaryDark">#00574B</color><color name="colorAccent">#D81B60</color><color name="colorRed">#F00</color><color name="colorBlack">#000</color><color name="colorWhite">#FFF</color><color name="colorhuise">#DCDCDC</color><color name="colorpink">#FF7F50</color>
</resources>

UI效果预览图：

第五步,引入第三步Mob短信验证服务

首先进入Mob平台，选择SMSSDK开始使用：

当然了，你先要注册一个帐号
然后我们创建一个新应用，这里名字就叫简易新闻：

然后会出现一个新的界面，这里会出现我们后面要用的AppKey与AppSecret，每个人的都不一样，选择添加SMSSDK服务：

点击添加之后，我们需要把这个服务添加到我们自己的模块中，我们在下载页面，选择SMSSDK进行下载：

按照上面说明，首先在project的根目录build.gradle中添加（注意不是你的项目中添加）：

// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {repositories {google()jcenter()}repositories {maven {url "http://mvn.mob.com/android"}}dependencies {classpath 'com.android.tools.build:gradle:3.2.0'classpath 'com.mob.sdk:MobSDK:2018.0319.1724'// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files}
}allprojects {repositories {google()jcenter()}
}task clean(type: Delete) {delete rootProject.buildDir
}

然后修改你的项目Moudle中的build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'com.mob.sdk'
android {compileSdkVersion 28MobSDK {appKey "2b85a17d997b2"appSecret "bc386e05d6171e915f1195858a9d017b"SMSSDK {}}defaultConfig {applicationId "com.example.frametest"minSdkVersion 16targetSdkVersion 28versionCode 1versionName "1.0"testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"vectorDrawables.useSupportLibrary = true}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'}}}

到这里，我们就可以通过代码来实现短信验证啦。

第六步，实现登录与用户信息存储

修改LoginActivity.class

package com.example.frametest.UserMode;import android.annotation.SuppressLint;
import android.content.Context;
import android.content.Intent;
import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;

}

第七步，new一个User类为表user_info存储使用

package com.example.frametest.UserMode;public class User {private int id;private String user_name;private String user_phone;private String user_pasw;private int user_age;private boolean user_sex;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getUser_name() {return user_name;}public void setUser_name(String user_name) {this.user_name = user_name;}public String getUser_phone() {return user_phone;}public void setUser_phone(String user_phone) {this.user_phone = user_phone;}public String getUser_pasw() {return user_pasw;}public void setUser_pasw(String user_pasw) {this.user_pasw = user_pasw;}public int getUser_age() {return user_age;}public void setUser_age(int user_age) {this.user_age = user_age;}public boolean isUser_sex() {return user_sex;}public void setUser_sex(boolean user_sex) {this.user_sex = user_sex;}
}

第八步修改MainActivity.class

package com.example.frametest;import android.content.DialogInterface;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.design.widget.NavigationView;

import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
import de.hdodenhof.circleimageview.CircleImageView;public class MainActivity extends AppCompatActivity {private android.support.v7.widget.Toolbar toolbar;private DrawerLayout mDrawerLayout;private NavigationView navigationView;private TabLayout tabLayout;private ViewPager viewPager;private List<String> list;private TextView tvhuoqu,tvName;String phonenumber;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);toolbar =  findViewById(R.id.toolbar);mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); //获取抽屉布局navigationView = (NavigationView) findViewById(R.id.nav_design);//获取菜单控件实例View v = navigationView.getHeaderView(0);CircleImageView circleImageView =(CircleImageView) v.findViewById(R.id.icon_image);tabLayout = (TabLayout) findViewById(R.id.tabLayout);viewPager = (ViewPager) findViewById(R.id.viewPager);list = new ArrayList<>();tvhuoqu = (TextView) findViewById(R.id.text_huoqu);}@Overrideprotected void onStart() {super.onStart();/* toolbar.setLogo(R.drawable.icon);//设置图片logo,你可以添加自己的图片*/toolbar.setTitle("简易新闻");setSupportActionBar(toolbar);ActionBar actionBar = getSupportActionBar();if (actionBar !=null){//通过HomeAsUp来让导航按钮显示出来actionBar.setDisplayHomeAsUpEnabled(true);//设置Indicator来添加一个点击图标actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_24dp);}navigationView.setCheckedItem(R.id.nav_call);//设置第一个默认选中navigationView.setNavigationItemSelectedListener(new  NavigationView.OnNavigationItemSelectedListener() {//设置菜单项的监听事件@Overridepublic boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {mDrawerLayout.closeDrawers();switch (menuItem.getItemId()) {case R.id.nav_call://每个菜单项的点击事件，通过Intent实现点击item简单实现活动页面的跳转。/*Intent intent = new Intent(MainActivity.this, Main2Activity.class);//第二个Main2Activity.class需要你自己new一个 Activity来做出其他功能页面startActivity(intent);*/break;case R.id.nav_friends:Toast.makeText(MainActivity.this, "你点击了好友", Toast.LENGTH_SHORT).show();break;case R.id.nav_location:Toast.makeText(MainActivity.this, "你点击了发布新闻，下步实现", Toast.LENGTH_SHORT).show();break;case R.id.nav_favorite:Toast.makeText(MainActivity.this, "你点击了个人收藏，下步实现", Toast.LENGTH_SHORT).show();break;case R.id.nav_settings:Toast.makeText(MainActivity.this,"需要做出登出功能，可扩展夜间模式，离线模式等,检查更新",Toast.LENGTH_LONG).show();break;case R.id.nav_exit:Intent intent = new Intent(MainActivity.this,LoginActivity.class);startActivityForResult(intent,1);break;default:}return true;}});list.add("头条");list.add("社会");list.add("国内");list.add("国际");list.add("娱乐");list.add("体育");list.add("军事");list.add("科技");list.add("财经");/* viewPager.setOffscreenPageLimit(1);*/viewPager.setAdapter(new FragmentStatePagerAdapter(getSupportFragmentManager()) {//得到当前页的标题，也就是设置当前页面显示的标题是tabLayout对应标题@Nullable@Overridepublic CharSequence getPageTitle(int position) {return list.get(position);}@Overridepublic Fragment getItem(int position) {NewsFragment newsFragment = new NewsFragment();//判断所选的标题，进行传值显示Bundle bundle = new Bundle();if (list.get(position).equals("头条")){bundle.putString("name","top");}else if (list.get(position).equals("社会")){bundle.putString("name","shehui");}else if (list.get(position).equals("国内")){bundle.putString("name","guonei");}else if (list.get(position).equals("国际")){bundle.putString("name","guoji");}else if (list.get(position).equals("娱乐")){bundle.putString("name","yule");}else if (list.get(position).equals("体育")){bundle.putString("name","tiyu");}else if (list.get(position).equals("军事")){bundle.putString("name","junshi");}else if (list.get(position).equals("科技")){bundle.putString("name","keji");}else if (list.get(position).equals("财经")){bundle.putString("name","caijing");}else if (list.get(position).equals("时尚")){bundle.putString("name","shishang");}newsFragment.setArguments(bundle);return newsFragment;}@NonNull@Overridepublic Object instantiateItem(@NonNull ViewGroup container, int position) {NewsFragment newsFragment = (NewsFragment)  super.instantiateItem(container, position);return newsFragment;}@Overridepublic int getItemPosition(@NonNull Object object) {return FragmentStatePagerAdapter.POSITION_NONE;}@Overridepublic int getCount() {return list.size();}});//TabLayout要与ViewPAger关联显示tabLayout.setupWithViewPager(viewPager);String inputText = load();if (!TextUtils.isEmpty(inputText)){//取出之前的手机号phonenumber =inputText;}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {//获取toolbar菜单项getMenuInflater().inflate(R.menu.toolbar,menu);return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {switch (item.getItemId()){//R.id.home修改导航按钮的点击事件为打开侧滑栏case android.R.id.home:mDrawerLayout.openDrawer(GravityCompat.START);

}

第九步，修改AndroidManifest.xml文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.frametest"><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><!-- mob发送短信权限 --><uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.RECEIVE_SMS" /><uses-permission android:name="android.permission.READ_SMS" /><uses-permission android:name="android.permission.GET_TASKS" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><applicationandroid:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/AppTheme"><activity android:name=".MainActivity"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity><activity android:name=".WebActivity" /><activity android:name=".UserMode.LoginActivity"></activity></application></manifest>

此时我们先看一下运行后的效果：

还可以在Mob查看我们短信验证记录：

此时我们还没有实现用户修改用户名的功能。

实现第一步，修改nav_header.xml布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="180dp"android:padding="10dp"android:orientation="horizontal"android:background="#80FFFF"><de.hdodenhof.circleimageview.CircleImageViewandroid:id="@+id/icon_image"android:layout_width="wrap_content"android:layout_height="wrap_content"android:src="@mipmap/mouse"android:layout_centerInParent="true"/><TextViewandroid:id="@+id/text_huoqu"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentBottom="true"android:textColor="@color/colorBlack"android:textSize="14sp"tools:ignore="HardcodedText" /><TextViewandroid:id="@+id/text_username"android:layout_above="@id/text_huoqu"android:textColor="@color/colorBlack"android:textSize="14sp"android:layout_width="wrap_content"android:layout_height="wrap_content"tools:ignore="HardcodedText"android:text="个人博客地址：https://blog.csdn.net/Tobey_r1"android:layout_toRightOf="@+id/text_huoqu" />
</RelativeLayout>

第二步，给侧滑栏编辑资料按钮添加点击事件

修改MainActivity.class：

第三步，添加点击事件对应的活动

new一个新的activity，User_DataActivity.class与activity_user_data.xml

activity_user_data.xml

<?xml version="1.0" encoding="utf-8"?>
