ott 平台架构 ott框架

如果你是刚学习这个，或者是对这个框架还不够了解它的工作机理，那么你可以在你去看看我的另一篇文章。

 

本篇文章我们接着上一篇的来讲，关于这个配置其实很简单，关键是怎么使用这个框架来写出更好的代码。在这里我们在上次工程的基础上新建一个抽象的事件类，这样方便程序的扩展。

import android.os.Bundle;

public abstract class RootEvent {
    // Data
    public Bundle data;
}

然后我们再新建两个事件类来继承上述抽象事件类：

import android.os.Bundle;

public class LeafEventA extends RootEvent {
    public enum EventA {
        EventA_1,
        EventA_2,
        EventA_3
    }
    public EventA what;
    public LeafEventA(EventA what) {
        this.what = what;
    }
    public LeafEventA(EventA what, Bundle data) {
        this.what = what;
        this.data = data;
    }
}

public class LeafEventB extends RootEvent {
    public enum EventB {
        EventB_1,
        EventB_2
    }
    public EventB what;
    public LeafEventB(EventB what) {
        this.what = what;
    }
    public LeafEventB(EventB what, Bundle data) {
        this.what = what;
        this.data = data;
    }
}

写好了事件，接下来我们要在MainActivity中通过点击按钮来发布，然后为了方便我们还是把订阅者方法同样写在MainActivity中：

public void postEventA_1(View v) {
    Bundle data=new Bundle();
    data.putString("EventA_1_Data","没错，我就是EventA_1的数据！");
    App.bus.post(new LeafEventA(LeafEventA.EventA.EventA_1,data));
}
public void postEventA_2(View v) {
    Bundle data=new Bundle();
    data.putString("EventA_2_Data","没错，我就是EventA_2的数据！");
    App.bus.post(new LeafEventA(LeafEventA.EventA.EventA_2,data));
}
public void postEventA_3(View v) {
    Bundle data=new Bundle();
    data.putString("EventA_3_Data","没错，我就是EventA_3的数据！");
    App.bus.post(new LeafEventA(LeafEventA.EventA.EventA_3,data));
}
public void postEventB_1(View v) {
    Bundle data=new Bundle();
    data.putString("EventB_1_Data","没错，我就是EventB_1的数据！");
    App.bus.post(new LeafEventB(LeafEventB.EventB.EventB_1,data));
}
public void postEventB_2(View v) {
    Bundle data=new Bundle();
    data.putString("EventB_2_Data","没错，我就是EventB_2的数据！");
    App.bus.post(new LeafEventB(LeafEventB.EventB.EventB_2,data));
}

上面都是各个按钮的点击事件，我是在布局文件中写下的onClick属性。

下面是A订阅者方法：

@Subscribe
public void onEvent(LeafEventA leafEventA){
    switch(leafEventA.what){
        case EventA_1:
            Log.i(TAG,"This is EventA_1"+"收到的数据是:"+leafEventA.data.getString("EventA_1_Data"));
            break;
        case EventA_2:
            Log.i(TAG,"This is EventA_2"+"收到的数据是:"+leafEventA.data.getString("EventA_2_Data"));
            break;
        case EventA_3:
            Log.i(TAG,"This is EventA_3"+"收到的数据是:"+leafEventA.data.getString("EventA_3_Data"));
            break;
        default:
    }
}

下面是B订阅者方法：

@Subscribe
public void onEvent(LeafEventB leafEventB){
    switch(leafEventB.what){
        case EventB_1:
            Log.i(TAG,"This is EventB_1"+"收到的数据是:"+leafEventB.data.getString("EventB_1_Data"));
            break;
        case EventB_2:
            Log.i(TAG,"This is EventB_2"+"收到的数据是:"+leafEventB.data.getString("EventB_2_Data"));
            break;
        default:
    }
}

OK ,接下来Ctrl+F9编译一下，然后运行，点击各个按钮查看打印信息：

06-30 13:23:14.454 12057-12057/com.myapplication I/MainActivity: This is EventA_1收到的数据是没错，我就是EventA_1的数据！
06-30 13:23:23.782 12057-12057/com.myapplication I/MainActivity: This is EventA_2收到的数据是没错，我就是EventA_2的数据！
06-30 13:23:25.913 12057-12057/com.myapplication I/MainActivity: This is EventA_3收到的数据是没错，我就是EventA_3的数据！
06-30 13:23:27.803 12057-12057/com.myapplication I/MainActivity: This is EventB_1收到的数据是没错，我就是EventB_1的数据！
06-30 13:23:29.547 12057-12057/com.myapplication I/MainActivity: This is EventB_2收到的数据是没错，我就是EventB_2的数据！

怎么样，是不是很给力。如果你说不是，我也同意，毕竟我也不是师者，想要传道授业解惑，怎奈何学识低浅，我们一起努力吧。
