所有的 Activity 必须继承至 MyActivity，如果使用 MVP 请继承至 MvpActivity，已经处理了 Activity 多重启动的问题，详情可点击此处查看
获取 Context 或者 Activity
public Context getContext()
public <A extends BaseActivity> A getActivity()
startActivity 方法优化
public void startActivity(Class<? extends Activity> cls)
public void startActivityFinish(Class<? extends Activity> cls)
public void startActivityFinish(Intent intent)
startActivityForResult 方法优化
public void startActivityForResult(Intent intent, ActivityCallback callback)
public void startActivityForResult(Intent intent, @Nullable Bundle options, ActivityCallback callback)
setResult 方法优化
public void finishResult(int resultCode)
public void finishResult(int resultCode, Intent data)
Activity 标题
public void setTitle(int titleId)
public void setTitle(CharSequence title)
public CharSequence getTitle()
Toast 方法
public void toast(CharSequence s)
public void toast(int id)
public void toast(Object object)
Handler 方法
public static Handler getHandler()
TitleBar 方法
public TitleBar getTitleBar()
TitleBar 监听方法（需要被重写）
// 标题栏左项被点击了，默认返回
public void onLeftClick(View v)
// 标题栏中间项被点击了
public void onTitleClick(View v)
// 标题栏右项被点击了
public void onRightClick(View v)
获取Activity，防止出现 getActivity() 为空
public FragmentActivity getFragmentActivity()
是否进行了懒加载
protected boolean isLazyLoad()
当前 Fragment 是否可见
public boolean isFragmentVisible()
跟 Activity 的同名方法效果一样
protected void onRestart()
根据资源 id 获取一个 View 对象
protected <T extends View> T findViewById(@IdRes int id)
protected <T extends View> T findActivityViewById(@IdRes int id)
跳转到其他Activity
public void startActivity(Class<? extends Activity> cls)
销毁当前 Fragment 所在的 Activity
public void finish()
获取系统服务
public Object getSystemService(@NonNull String name)
Fragment返回键被按下时回调（只做预留方法，没有效果）
public boolean onKeyDown(int keyCode, KeyEvent event)
Toast 方法
public void toast(CharSequence s)
public void toast(int id)
public void toast(Object object)
获取 RecyclerView 或者 Context
public RecyclerView getRecyclerView()
public Context getContext()
布局摆放器（可以被重载，由于 RecyclerView 不能没有设置 LayoutManager，这里设置了默认的）
protected RecyclerView.LayoutManager getDefaultLayoutManager(Context context) {
return new LinearLayoutManager(context);
}
分页逻辑预留方法
public int getPageNumber()
public void setPageNumber(int pageNumber)
public boolean isLastPage()
public void setLastPage(boolean lastPage)
标记方法
public Object getTag()
public void setTag(Object tag)
操作数据集合
public void setData(List<T> data)
public List<T> getData()
public void addData(List<T> data)
public void clearData()
操作单个数据
public T getItem(int position)
public void setItem(int position, T item)
public void addItem(T item)
public void addItem(int position, T item)
public void removeItem(T item)
public void removeItem(int position)
MyRecyclerViewAdapter.ViewHolder 方法
public final View getItemView()
public final <V extends View> V findViewById(@IdRes int viewId)
public final ViewHolder setText(@IdRes int viewId, @StringRes int resId)
public final ViewHolder setText(@IdRes int viewId, String text)
public final ViewHolder setVisibility(@IdRes int viewId, int visibility)
public final ViewHolder setColor(@IdRes int viewId, @ColorInt int color)
public final ViewHolder setImage(@IdRes int viewId, @DrawableRes int resId)
监听方法（必须在 RecyclerView.setAdapter 之前调用）
public void setOnItemClickListener(OnItemClickListener l)
public void setOnChildClickListener(@IdRes int childId, OnChildClickListener l)
public void setOnItemLongClickListener(OnItemLongClickListener l)
public void setOnChildLongClickListener(@IdRes int childId, OnChildLongClickListener l)
public void setOnScrollingListener(OnScrollingListener l)
MyListViewAdapter 和 MyRecyclerViewAdapter 差不多，只不过没有上面这些监听方法，因为 ListView 本身已经自带这些了
