ActivityLifecycleCallbacks

在android.app; Application中ActivityLifecycleCallbacks 对activity的生命周期事件进行集中处理

    public interface ActivityLifecycleCallbacks {        void onActivityCreated(Activity activity, Bundle savedInstanceState);        void onActivityStarted(Activity activity);        void onActivityResumed(Activity activity);        void onActivityPaused(Activity activity);        void onActivityStopped(Activity activity);        void onActivitySaveInstanceState(Activity activity, Bundle outState);        void onActivityDestroyed(Activity activity);    }

在Application中注册ActivityLifecycleCallbacks接口

  registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {            @Override            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivityCreated--------]");                addActivity(activity);        //把activity 添加Activity到堆栈            }            @Override            public void onActivityStarted(Activity activity) {                LogUtils.i("[--------"+activity.getPackageName()+"--------onActivityStarted--------]");            }            @Override            public void onActivityResumed(Activity activity) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivityResumed--------]");            }            @Override            public void onActivityPaused(Activity activity) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivityPaused--------]");            }            @Override            public void onActivityStopped(Activity activity) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivityStopped--------]");            }            @Override            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivitySaveInstanceState--------]");            }            @Override            public void onActivityDestroyed(Activity activity) {                LogUtils.i("[--------"+getFragmentNameTAG(activity)+"--------onActivityDestroyed--------]");                removeActivity(activity);            }        });

让activity实现自定义接口;

public interface IActivity {    @LayoutRes    int getContentViewLayoutRes();    void initData();}

在ActivityLifecycleCallbacks中onActivityCreated方法中给activity设置布局文件

 if (activity instanceof IActivity){     activity.setContentView(((IActivity) activity).getContentViewLayoutRes());    ((IActivity)activity).initData(); }else if(activity instanceof VActivity){...}

在activity中实现butterknife绑定

public class ButterKnifeSerializable implements Serializable {    private Unbinder unbinder;    public void setUnbinder(Unbinder unbinder){        this.unbinder = unbinder;    }    public Unbinder getUnbinder(){        return unbinder;    }}

在ActivityLifecycleCallbacks中onActivityCreated方法中实现butterknife绑定

     ButterKnifeSerializable bean = new ButterKnifeSerializable();     Unbinder unbinder = ButterKnife.bind(activity);     bean.setUnbinder(unbinder);     activity.getIntent().putExtra("ButterKnifeSerializable", bean);

在ActivityLifecycleCallbacks中onActivityDestroyed方法中实现butterknife解绑

    ButterKnifeSerializable bean = (ButterKnifeSerializable) activity.getIntent().getSerializableExtra("ButterKnifeSerializable");    bean.getUnbinder().unbind();
