Android 注册小实例

这两天在学习Android，看了几天视频以后,因为之前做过一个小的Android项目感觉看完视频没有什么很难的。但是因为我们做的那个项目之前都是封装好的，所以觉得好多东西都不会，没有自己搭建起一个项目。所以决定实战一下可能自己搭建的过程中就会遇到很多问题。做实例不是从登陆就是从注册开始做，我就从注册开始做起。

1.建包

首先建立一个项目里面有自己规定好的包，如图：

因为我只做了个注册，所以没有把包分的那么仔细。应该还有存放adpater，工具类等等，项目大的话把他们都分开。

2.编写界面布局activity_regesiter.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:background="#F0F0F0"    android:orientation="vertical" >         <LinearLayout style="@style/top_title_style" >        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="5dp"            android:layout_marginTop="2dp"            android:layout_weight="1"            android:gravity="center"            android:paddingLeft="4dp"            android:text="注册"            android:textColor="#FFFFFF"            android:textSize="20sp" />    </LinearLayout>    <RelativeLayout        android:layout_width="fill_parent"        android:layout_height="45dp"        android:background="#FFFFFF"        android:minHeight="50.0dip"        android:layout_marginTop="30.0dip"        android:paddingLeft="14.0dip"        android:paddingRight="0dip" >        <EditText            android:id="@+id/et_register_username_id"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_marginLeft="0dp"            android:background="#FFFFFF"            android:hint="手机号"            android:paddingLeft="15dip"            android:textColorHint="#BEBEBE"            android:textSize="18sp" />                <Button            android:id="@+id/bt_getcode_id"            android:layout_width="140dp"            android:layout_height="match_parent"            android:layout_centerVertical="true"            android:layout_marginLeft="200dp"            android:background="@drawable/shape1"            android:gravity="center"            android:text="获取验证码"            android:textColor="#FFFFFF"            android:textSize="14sp" />    </RelativeLayout>    <View style="@style/PersonalLine" />    <RelativeLayout        android:layout_width="fill_parent"        android:layout_height="45dp"        android:background="#FFFFFF"        android:minHeight="50.0dip"        android:paddingLeft="14.0dip"        android:paddingRight="12.0dip" >        <EditText            android:id="@+id/et_register_code_id"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_marginLeft="0dp"            android:background="@null"            android:hint="请输入验证码"            android:paddingLeft="15dip"            android:textColorHint="#BEBEBE"            android:textSize="18sp" />            </RelativeLayout>    <View style="@style/PersonalLine" />    <RelativeLayout        android:layout_width="fill_parent"        android:layout_height="45dp"        android:background="#FFFFFF"        android:minHeight="50.0dip"        android:paddingLeft="14.0dip"        android:paddingRight="12.0dip" >        <EditText            android:id="@+id/et_register_password_id"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_marginLeft="0dp"            android:background="@null"            android:hint="请输入密码"            android:inputType="textPassword"            android:paddingLeft="15dip"            android:textColorHint="#BEBEBE"            android:textSize="18sp" />    </RelativeLayout>    <View style="@style/PersonalLine" />    <Button        android:id="@+id/bt_register_id"        android:layout_width="300dp"        android:layout_height="40dp"        android:layout_marginTop="40dp"        android:layout_gravity="center_horizontal"        android:background="@drawable/shape2"        android:gravity="center"        android:text="注  册"        android:textColor="#FFFFFF"        android:textSize="18sp" /></LinearLayout>

3.抽取公共类URL，存放URL地址的

public class URL {private static String urlPrefix = "http://120.25.249.94/jrkj/GetJrkjData.ashx?op=";/** * 注册 */public final static String REGISTER_URL = urlPrefix + "RegistUser";}<span style="color:#3366ff;"></span>

4.编写实体UserEntity

/** * 注册实体类 * @author xiao * */public class UserEntity {private String result;private String data;public String getData() {return data;}public void setData(String data) {this.data = data;}public String getResult() {return result;}public void setResult(String result) {this.result = result;}}<span style="color:#3366ff;"></span>

5.编写RegesiterActivity

public class RegesiterActivity extends Activity implements OnClickListener {// 定义页面控件private EditText etUsername;private EditText etcode;private EditText etpassword;private Button btnCodeButton;private Button btnRegesiterButton;private TextView textView;// 定义变量private String userName;private String passWord;// 客户端输入的验证码private String valicationCode;// 服务器端获取的验证码private static String serverValicationCode;public boolean isChange = false;private boolean tag = true;private int i = 60;Thread thread = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_regesiter);// 初始化页面控件initView();}/** * 初始化页面控件事件 */public void initView() {etUsername = (EditText) findViewById(R.id.et_register_username_id);etpassword = (EditText) findViewById(R.id.et_register_password_id);etcode = (EditText) findViewById(R.id.et_register_code_id);btnCodeButton = (Button) findViewById(R.id.bt_getcode_id);btnRegesiterButton = (Button) findViewById(R.id.bt_register_id);btnCodeButton.setOnClickListener(this);btnRegesiterButton.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.bt_getcode_id:// 判断用户名和密码是否输入if (!isvalidate())break;btnCodeButton.setText("获取验证码");btnCodeButton.setClickable(true);isChange = true;changeBtnGetCode();getValidateCode();break;case R.id.bt_register_id:register();break;default:break;}}/** * 判断用户名和密码是否输入 *  * @return */private boolean isvalidate() {// 获取控件取值String username = etUsername.getText().toString().trim();String password = etpassword.getText().toString().trim();if (username == null || username.equals("")) {Toast.makeText(this, "手机号不能为空", Toast.LENGTH_SHORT).show();return false;}if (password == null || username.equals("")) {Toast.makeText(this, "密码不能为空", Toast.LENGTH_SHORT).show();return false;}return true;}/** * 点击验证码按钮 */private void changeBtnGetCode() {thread = new Thread() {@Overridepublic void run() {if (tag) {while (i > 0) {i--;if (RegesiterActivity.this == null) {break;}RegesiterActivity.this.runOnUiThread(new Runnable() {@Overridepublic void run() {btnCodeButton.setText("获取验证码(" + i + ")");btnCodeButton.setClickable(false);}});try {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}tag = false;}i = 60;tag = true;if (RegesiterActivity.this != null) {RegesiterActivity.this.runOnUiThread(new Runnable() {@Overridepublic void run() {btnCodeButton.setText("获取验证码");btnCodeButton.setClickable(true);}});}};};thread.start();}/** * 获取验证码 *  * @return */public boolean getValidateCode() {String name = etUsername.getText().toString().trim();String code = etcode.getText().toString().trim();if (name.equals("")) {Toast.makeText(this, "请输入用户名或手机号!", Toast.LENGTH_SHORT).show();return false;} else {userName = name;valicationCode = code;Thread codeThread = new Thread(codeRunnable);codeThread.start();}return true;}/** 实例化的handler */private Handler mHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {switch (msg.what) {case 1:serverValicationCode = (String) msg.obj;Toast.makeText(getBaseContext(), "获取验证码成功！", Toast.LENGTH_SHORT).show();break;case -1:Toast.makeText(getBaseContext(), "获取验证码失败！", Toast.LENGTH_SHORT).show();break;case 0:Toast.makeText(getBaseContext(), "哎呀,出错啦..", Toast.LENGTH_SHORT).show();break;case 2:Toast.makeText(getBaseContext(), "注册成功！", Toast.LENGTH_SHORT).show();Intent intent = new Intent();intent.setClass(RegesiterActivity.this, EditxuqiuActivity.class);startActivity(intent);break;default:break;}super.handleMessage(msg);}};/** 定义获取验证码的子线程 */private Runnable codeRunnable = new Runnable() {@Overridepublic void run() {Message msg = new Message();UserEntity userEntity = null;try {userEntity = requestByHttpPost();// 获取服务器数据serverValicationCode = userEntity.getResult();// 返回true则将消息的what值为1，为false则what为-1，异常为0if (serverValicationCode.equals("")) {msg.what = -1;} else {msg.what = 1;msg.obj = serverValicationCode;}} catch (Exception e) {msg.what = 0;e.printStackTrace();}mHandler.sendMessage(msg);}};/** * 从服务器获取验证码 * @return * @throws Exception */public UserEntity requestByHttpPost() throws Exception {UserEntity userEntity = null;String urlString = URL.REGISTER_URL;HttpGet getMethod = new HttpGet(urlString);HttpClient httpClient = new DefaultHttpClient();try {HttpResponse response = httpClient.execute(getMethod); // 发起GET请求System.out.println(response.toString());String strResponseString = EntityUtils.toString(response.getEntity(), "utf-8");userEntity = JSON.parseObject(strResponseString, UserEntity.class);} catch (ClientProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return userEntity;}/** * 注册 *  */public void register() {// 1.首先判断输入的值是否有效// 2.然后判断输入的验证码是否有效（防止没有点击获取验证码自己填的错误验证码)// 3.最后注册if (isValid()) {if (valicationCode.equals(serverValicationCode)) {Thread thread = new Thread(sRunnable);thread.start();} else {Toast.makeText(this, "输入的验证码不正确!", Toast.LENGTH_SHORT).show();}}}/** * 注册之前判断数据是否为空 *  */public boolean isValid() {userName = etUsername.getText().toString().trim();valicationCode = etcode.getText().toString().trim();passWord = etpassword.getText().toString().trim();if (userName.equals("")) {Toast.makeText(this, "请输入手机号!", Toast.LENGTH_SHORT).show();return false;}if (valicationCode.equals("")) {Toast.makeText(this, "验证码不能为空!", Toast.LENGTH_SHORT).show();return false;}if (!serverValicationCode.equals(valicationCode)) {Toast.makeText(this, "验证码错误", Toast.LENGTH_SHORT).show();return false;}if (passWord.equals("")) {Toast.makeText(this, "密码不能为空!", Toast.LENGTH_SHORT).show();return false;} else if (passWord.length() < 6) {Toast.makeText(this, "密码至少6位!", Toast.LENGTH_SHORT).show();return false;}return true;}/** 自定义注册子线程 */private Runnable sRunnable = new Runnable() {@Overridepublic void run() {Message msg = new Message();try {//获取数据UserEntity userentity=getRegesiterData();String result=userentity.getResult();// 返回值为success表示成功if (result.equals("success")) {msg.what = 2;msg.obj = result;} else if (result.equals("false")) {msg.what = -1;}} catch (Exception e) {msg.what = 0;e.printStackTrace();}mHandler.sendMessage(msg);}};/** * 从服务器获取注册是否成功的消息 * @return * @throws Exception */public UserEntity getRegesiterData() throws Exception {String urlString = URL.REGISTER_URL;UserEntity userEntity = null;HttpGet getMethod = new HttpGet(urlString);HttpClient httpClient = new DefaultHttpClient();try {HttpResponse response = httpClient.execute(getMethod); // 发起GET请求System.out.println(response.toString());String strResponseString = EntityUtils.toString(response.getEntity(), "utf-8");userEntity = JSON.parseObject(strResponseString, UserEntity.class);} catch (ClientProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return userEntity;}}<span style="color:#3366ff;"></span>

6.配置AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.smile.jrkjshizhan"    android:versionCode="1"    android:versionName="1.0" >    <!-- 设置通信权限 -->    <uses-permission android:name="android.permission.INTERNET" />        <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@android:style/Theme.Light.NoTitleBar" >        <!-- 注册 -->        <activity            android:name="com.smile.jrkjshizhan.ui.RegesiterActivity"            android:label="@string/app_name" >       <!-- 设置启动开启页面 -->            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>                    </application> </manifest>

最后一定不要忘记配置通信权限，我就是忘记了配置通信权限，所以访问不了借口的数据。

给大家上一个注册图：

原本想着录屏来着，模拟器怎么也打不开，就给大家上一张图片吧。。。

这是一个完整的注册实例，大家按照这个写，就能完成注册的功能。献给那些初学者们！欢迎大家多多提意见！最后在Activity中有两次访问url，一次是从服务器中获取验证码，一次是从服务器中获取注册信息，里面有好多重复的代码，目前正在封装中，稍后呈现给大家。
