android服务器Bmob的使用

来源：互联网发布：iphone5s没有4g网络编辑：程序博客网时间：2024/06/07 01:01

使用Bmob无需再造应用后端，便能轻松拥有应用开发的各种后端能力支持，减少了开发者将应用从idea到产品（成品）的时间，我们提供了大量标准的API接口，根据需要接入相关服务，开发者可以更加专注于应用的开发，让产品交付更快速。

话不多少先看代码

实现提交数据的功能

public class MainActivity extends Activity {    private EditText edt1, edt2;    private Button btn1,btn2;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        edt1 = (EditText) findViewById(R.id.edt1);        edt2 = (EditText) findViewById(R.id.edt2);        btn1 = (Button) findViewById(R.id.btn1);        btn2 = (Button) findViewById(R.id.btn2);        // 初始化SDK        Bmob.initialize(this, "c945e1b1070e900af132bc082d22aae8");        btn1.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                String name = edt1.getText().toString();                String password = edt2.getText().toString();                // TODO Auto-generated method stub                if (name.equals("") || password.equals("")) {                    return;                }                FeedBack feedbackobj = new FeedBack();                feedbackobj.setName(name);                feedbackobj.setFeedback(password);                feedbackobj.save(getApplicationContext(),new SaveListener() {                    @Override                    public void onSuccess() {                        // TODO Auto-generated method stub                        Toast.makeText(getApplicationContext(), "y", Toast.LENGTH_SHORT).show();                    }                    @Override                    public void onFailure(int arg0, String arg1) {                        // TODO Auto-generated method stub                        Toast.makeText(getApplicationContext(), "N", Toast.LENGTH_SHORT).show();                    }                });            btn2.setOnClickListener(new OnClickListener() {                @Override                public void onClick(View v) {                    // TODO Auto-generated method stub                }            });            }        });    }}

用javabean来装数据这里是用的FeedBack.java
代码如下

public class FeedBack extends BmobObject {private String name;private String feedback;public String getName() {    return name;}public void setName(String name) {    this.name = name;}public String getFeedback() {    return feedback;}public void setFeedback(String feedback) {    this.feedback = feedback;}}

上面的代码是用来提交数据的，基本布局如下

提交数据到云数据库

这里写图片描述

注意使用前需要导包

Bmob还可以实现查询

    btn2.setOnClickListener(new OnClickListener() {                    String str1 = edt3.getText().toString();                    @Override                    public void onClick(View v) {                        // TODO Auto-generated method stub                        BmobQuery<FeedBack> query = new BmobQuery<FeedBack>();                        //query.addWhereEqualTo("name", str);                        query.findObjects(getApplicationContext(), new FindListener<FeedBack>() {                            @Override                            public void onError(int arg0, String arg1) {                                // TODO Auto-generated method stub                                Toast.makeText(getApplicationContext(), "N", Toast.LENGTH_SHORT).show();                            }                            @Override                            public void onSuccess(List<FeedBack> feedbacks) {                                // TODO Auto-generated method stub                                AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());                                builder.setTitle("query");                                String str = "";                                for (FeedBack feedback : feedbacks) {                                    str += feedback.getName() + ":" + feedback.getFeedback() + "\n";                                }                                builder.setMessage(str);                                builder.create().show();                            }                        });                    }                });

消息推送的功能

public void pushAll(View view) {        BmobPushManager push = new BmobPushManager(getApplicationContext());        push.pushMessageAll("Test");    }``新建一个servers``public class MyPushMessageReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        String Message = "";        if (intent.getAction().equals(PushConstants.ACTION_MESSAGE)) {            String msg = intent.getStringExtra(PushConstants.EXTRA_PUSH_MESSAGE_STRING);            Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();            JSONTokener jsontoken = new JSONTokener(msg);            try {                JSONObject object = (JSONObject) jsontoken.nextValue();                Message = object.getString("alert");            } catch (JSONException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }NotificationManager manager=(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);            Notification notification=new Notification();            manager.notify(R.drawable.ic_launcher,notification);        }    }}

       <service        android:label="PushService"        android:name="cn.bmob.push.lib.service.PushService"        android:process="cn.bmob.push"        android:exported="true">         <intent-filter>             <action android:name="cn.bmob.push.lib.service.PushService"/>         </intent-filter>    </service>    <receiver android:name="cn.bmob.push.PushReceiver" >        <intent-filter>            <!-- 系统启动完成后会调用 -->            <action android:name="android.intent.action.BOOT_COMPLETED" />                           <!-- 解锁完成后会调用 -->            <action android:name="android.intent.action.USER_PRESENT" />            <!-- 监听网络连通性 -->            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />                       </intent-filter>    </receiver>    <!-- 第四部中创建的消息接收器，在这里进行注册 -->    <receiver android:name="com.example.bmob.MyPushMessageReceiver">         <intent-filter >              <action android:name="cn.bmob.push.action.MESSAGE"/>         </intent-filter>    </receiver>

所需要调用的权限

<!-- 允许联网 -->    <uses-permission android:name="android.permission.INTERNET" />    <!-- 获取GSM（2g）、WCDMA（联通3g）等网络状态的信息 -->    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <!-- 获取wifi网络状态的信息 -->    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <!-- 保持CPU 运转，屏幕和键盘灯有可能是关闭的,用于文件上传和下载 -->    <uses-permission android:name="android.permission.WAKE_LOCK" />    <!-- 获取sd卡写的权限，用于文件上传和下载 -->    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <!-- 允许读取手机状态 用于创建BmobInstallation -->    <uses-permission android:name="android.permission.READ_PHONE_STATE" />   <!--BmobSDK所需的权限 -->    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <!--推送所需的权限-->    <uses-permission android:name="android.permission.RECEIVE_USER_PRESENT" />    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
