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();
