android服务器Bmob的使用

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，

提交数据到云数据库

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);
        }

    }

}
