1 Introduction
In the last post Fun Things ④ OneNET MQTT service platform - The remote control LED (device self-registration) + Android App control , the blogger offers a complete App Mqtt agreement OneNet intelligent lamp. So, in order to facilitate the development and expansion of bloggers here briefly source design.
2. Download the source code
- Go to blogger technical exchange group group file download:
3. source code analysis
3.1 App Development Tools
- Android Studio, official certification tools, your own environment and configure the AS Java tools, bloggers currently belong to the latest version.
3.2 overall structure of the code
- After the download source introduced top down Android Studio, see the following structure:
bloggers developed herein for convenience, the three separation module: - app_common, commonly common module, such as various tools (tools printing log time format conversion tools)
- app_ormlib, database services (not used here, in order to later expand the reserve)
- app_widget, the UI used, base assembly, including a package base activity class, recyclerview, mvp and widely used design framework I
- app: this is our main business code.
3.3 MVP analytical framework
- As for what is called the MVP, bloggers do not speak here, please Baidu own. The following code constitutes the main framework for MVP:
Model: focus on data processing
View: focus on the page display
Presenter: call to coordinate the relationship between the Model and the View - Next, look at the code-based business MVP architecture:
by name, you can quickly know exactly corresponding to the service: - MQTT configuration page: OneNetConfigXXXX
- A list of the main page: MainXXXXX
- On the application page: AboutMeXXXX
- Expand the page: XXXXXXX
Next, we pick a page to explain, to facilitate understanding MVP work.
3.4 Main control the main page parsing
3.4.1 MVP Agreement
/**
* mvp 主页面协议 presenter层
*/
public interface IMainContract {
// model层
interface IMainModel extends IBaseModel {
void loadData(Context context, ICallBack<List<OneNetDeviceModel>> callBack);
void updateDeviceDetail(Context context,OneNetDeviceModel model, ICallBack<String> callBack);
}
//view层
interface IMainView extends IBaseView {
void showLoading(String loadmsg);
void dismissLoading(OnDismissCallbackListener callback);
void refreshList(List<OneNetDeviceModel> list);
}
}3.4.2 Model layer - data processing
- We are concerned about Main relevant code:
public class MainModel implements IMainContract.IMainModel {
SimpleTask task;
//获取设备列表
@Override
public void loadData(Context context, final ICallBack<List<OneNetDeviceModel>> callBack) {
if(task != null && task.getStatus()== AsyncTask.Status.RUNNING){
task.cancel(true);
}
task = new SimpleTask() {
GetOneNetDeviceListEntity entity;
@Override
protected void onPreExecute() {
entity = new GetOneNetDeviceListEntity();
}
@Override
protected Object doInBackground(String... strings) {
return entity.request();
}
@Override
protected void onPostExecute(Object o) {
String result = (String) o;
if("200".equals(result)){
if(entity.data != null && entity.data.devices.size()!=0) {
List<OneNetDeviceModel> list = new ArrayList<>();
for(OneNetDeviceModel model:entity.data.devices){
if(!model.getId().equals(PreferenceUtil.getInstance().getDeviceId())){
list.add(model);
}
}
callBack.onSuccess(list);
}
}else {
callBack.onFaild(result);
}
}
};
task.startTask();
}
//更新设备信息
@Override
public void updateDeviceDetail(Context context, final OneNetDeviceModel model, final ICallBack<String> callBack) {
if(task != null && task.getStatus()== AsyncTask.Status.RUNNING){
task.cancel(true);
}
task = new SimpleTask() {
UpdateOneNetDeviceDetailEntity entity;
@Override
protected void onPreExecute() {
entity = new UpdateOneNetDeviceDetailEntity(model.getId());
}
@Override
protected Object doInBackground(String... strings) {
return entity.request(model);
}
@Override
protected void onPostExecute(Object o) {
String result = (String) o;
if("200".equals(result)){
callBack.onSuccess("更新成功");
}else {
callBack.onFaild(result);
}
}
};
task.startTask();
}
}
3.4.3 View layer processing -UI
/**
* @author wty
* @Description 控制页面
**/
public class MainActivity extends BaseActivity<MainPresenter> implements IMainContract.IMainView {
@Bind(R.id.listview)
XRecyclerView listview;
DeviceListAdapter adapter;
public static void startActivity(Activity activity) {
Intent intent = new Intent(activity, MainActivity.class);
activity.startActivity(intent);
}
@Override
public MainPresenter getPresenter() {
return new MainPresenter();
}
@Override
public void onInitView(Bundle savedInstanceState) {
/**
* 第一个参数是服务器地址
* 第二个参数是用户名
* 第三个参数是密码
* 第四个参数是客户端ID
* 第五个参数是主题
**/
MqttManager
.getInstance()
.creatConnect(
AppConstant.RequestUrl.ONENET_MQTT,
PreferenceUtil.getInstance().getProductId(),
PreferenceUtil.getInstance().getApiKey(),
PreferenceUtil.getInstance().getDeviceId(),
"esp8266");
getDefaultNavigation().setTitle("OneNet智能灯");
getDefaultNavigation().getLeftButton().setButton("配置", new View.OnClickListener() {
@Override
public void onClick(View v) {
OneNetMqttConfigActivity.startActivity(MainActivity.this);
finish();
}
});
getDefaultNavigation().getRightButton().setButton("关于应用", new View.OnClickListener() {
@Override
public void onClick(View v) {
AboutActivity.startActivity(MainActivity.this);
}
});
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
listview.setLayoutManager(layoutManager);
listview.setPullRefreshEnabled(false);
listview.setLoadingMoreEnabled(false);
List<OneNetDeviceModel> data = new ArrayList<>();
adapter = new DeviceListAdapter(this,data,mPresenter);
listview.setAdapter(adapter);
mPresenter.refreshList(MainActivity.this);
}
@Override
protected boolean isEnableStatusBar() {
return true;
}
@Override
protected List<String> validate() {
List<String> list = super.validate();
return list;
}
@Override
protected void onDestroy() {
super.onDestroy();
MqttManager.release();
}
@Override
public int getLayoutResource() {
return R.layout.activity_main;
}
@Override
public void refreshList(List<OneNetDeviceModel> list) {
adapter.retsetData(list);
}
}
3.4.4 Presenter layer - intermediate layer Coordination
/**
* 主页面 presenter
*/
public class MainPresenter extends BasePresenter<IMainContract.IMainView> {
private IMainContract.IMainModel mMainModel;
public MainPresenter(){
mMainModel = new MainModel();
}
public void refreshList(Context context){
mView.showLoading("获取设备列表中...");
mMainModel.loadData(context, new ICallBack<List<OneNetDeviceModel>>() {
@Override
public void onSuccess(final List<OneNetDeviceModel> list) {
mView.refreshList(list);
mView.dismissLoading();
}
@Override
public void onFaild(String msg) {
mView.dismissLoading(new OnDismissCallbackListener(msg, SweetAlertDialog.ERROR_TYPE));
}
});
}
public void updateDeviceDetail(final Context context, OneNetDeviceModel model){
mView.showLoading("更新设备信息中...");
mMainModel.updateDeviceDetail(context,model, new ICallBack<String>() {
@Override
public void onSuccess(final String result) {
mView.dismissLoading();
refreshList(context);
}
@Override
public void onFaild(String msg) {
mView.dismissLoading(new OnDismissCallbackListener(msg, SweetAlertDialog.ERROR_TYPE));
}
});
}
}
Basically, each page are in accordance with the MVP design ideas to analyze it, very simple.
4. Summary
In short, experts do not spray.
