Android practice simple tutorial-23rd gun (Baas-based user registration and login module implementation !), Androidbaas

Next, let's take a look at the code in the last two articles based on the APIS provided by Bmob.

1. registration page xml:

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent"> <TableLayout android: id = "@ + id/tl" android: layout_width = "match_parent" android: layout_height = "wrap_content"> <TableRow> <TextView android: id = "@ + id/TV _name" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "username: "/> <EditText android: id =" @ + id/et_username "android: layout_width =" wrap_content "android: layout_height =" wrap_content "android: layout_weight =" 5 "android: text = ""/> </TableRow> <TextView android: id = "@ + id/TV _password" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "Password:"/> <EditText android: id = "@ + id/et_password" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "5" android: text = ""/> </TableRow> </TableLayout> <Button android: id = "@ + id/register" android: layout_width = "match_parent" android: layout_height = "wrap_content" android: layout_below = "@ + id/tl" android: onClick = "submit" android: text = "register"/> </RelativeLayout>

2. registration page. java:

", 3). show () ;}@ Overridepublic void onError (int arg0, String arg1) {// TODO Auto-generated method stub }});}}}

3. logon interface. xml:

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent"> <TableLayout android: id = "@ + id/tllayout" android: layout_width = "match_parent" android: layout_height = "wrap_content"> <TableRow> <TextView android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "username:"/> <EditText android: id = "@ + id/et_usernamelogin" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "5" android: text = ""/> </TableRow> <TextView android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "Password:"/> <EditText android: id = "@ + id/et_passwordlogin" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: password = "true" android: layout_weight = "5" android: text = ""/> </TableRow> </TableLayout> <Button android: id = "@ + id/login" android: layout_width = "match_parent" android: layout_height = "wrap_content" android: layout_below = "@ + id/tllayout" android: text = "login"/> </RelativeLayout>

4. logon interface. java:

Package com. example. logintest; import java. util. list; import cn. bmob. v3.Bmob; import cn. bmob. v3.BmobQuery; import cn. bmob. v3.listener. findListener; import cn. bmob. v3.listener. saveListener; import android. app. activity; import android. content. dialogInterface; import android. content. intent; import android.

", 3 ). show () ;}}@ Overridepublic void onError (int arg0, String arg1) {// TODO Auto-generated method stub }});}}});}}

5. log on successfully. 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: orientation = "vertical"> <TextView android: layout_width = "match_parent" android: layout_height = "wrap_content" android: text = "Login successful!

6. logon successful. java:

package com.example.logintest;import android.app.Activity;import android.os.Bundle;public class Success extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.success);}}

7. javabean. java:

package com.example.logintest;import cn.bmob.v3.BmobObject;public class User extends BmobObject {private String userPassword;public String getUserPassword() {return userPassword;}public void setUserPassword(String userPassword) {this.userPassword = userPassword;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}private String userName;}

8. configuration file:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.logintest"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.READ_LOGS" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.logintest.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity android:name="com.example.logintest.Login" >        </activity>        <activity android:name="com.example.logintest.Success" >        </activity>    </application></manifest>
