MVP框架，焦点框架，fragment框架，ExoPlayer媒体播放器 ###效果图

###焦点

<com.iptv.hq.ui.views.BorderImageView
        android:id="@+id/item_1"
        android:layout_width="@dimen/px217"
        android:layout_height="@dimen/px261"
        android:clickable="true"
        android:focusable="true" />

##MVP框架抽取

public abstract class BaseActivity<M extends IModel, V extends IView, P extends IPresenter<V, M>> {
protected P mPresenter;
protected M mModel;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mModel = createModel();
    mPresenter = createPresenter();
    mPresenter.onAttach((V) this, mModel);
}

protected abstract M createModel();

protected abstract P createPresenter();


@Override
protected void onDestroy() {
    super.onDestroy();
    mPresenter.onDetach();
    Runtime.getRuntime().gc();
    System.runFinalization();
    Runtime.getRuntime().gc();
}

}

###Presenter

public abstract class IPresenter<V extends IView, M extends IModel> {
public WeakReference<IView> iView;
public WeakReference<IModel> iModel;

public void onAttach(V iView, M model) {
    this.iView = new WeakReference<IView>(iView);
    this.iModel = new WeakReference<IModel>(model);
}

public void onDetach() {
    iView.clear();
    iModel.clear();
}

public M getIModel() {
    return (M) iModel.get();
}

public V getIView() {
    return (V) iView.get();
}

}

##Fragment

###Fragment是基于fragmentation进行拓展的（详情请参考：https://github.com/YoKeyword/Fragmentation），在此基础上增加了LoadingFragment,事件分发。并简化了Fragment之间的通讯

####Event 无参数无返回的事件

####PEvent 有参数无返回值的事件

####PREvent 有参数和返回值的事件

####REvent 有返回值无参数的事件

###EventManager 事件的管理者

  //存储一个事件
  EventManager.getInstance().post(new PEvent<ISupportFragment>("loadFragment") {
        @Override
        public void event(ISupportFragment iSupportFragment) {
            loadFragment(iSupportFragment);
        }
    });

 //执行一个事件
   EventManager.getInstance().invokeEvent("loadFragment",OnlineFragment.newInstance(),true);

##ExoPlayer播放器（详情请阅读：https://github.com/google/ExoPlayer）

##扩展了ffmpeg库增加了ffmpeg音频解码，进行了简单的封装，修改了源代码，使其支持左右声道的切换，增加了均衡器

.......
 exoplay = (ExoVideoView) findViewById(R.id.exoplay);
 exoplay.play(videoInfo);

@Override   
protected void onResume() {
    super.onResume();
    exoplay.resume();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    exoplay.destroy();
}

@Override
protected void onPause() {
    super.onPause();
    exoplay.pause();
}
