前言:

最近发现之前封装的结构,如果作为一个module依赖来开发时就不是很好用了.只能慢慢改了.

之前不好的地方：

1.Toolbar与ContentView写死在layout，如想要封装loadingView(根据请求状态,显示不同页面),非常麻烦. 2.Toolbar复用是通过include,改动即需要修改layout,也需要修改代码. 3.PResenter不能很好的控制Toolbar.

思路:

1.参考源码非NoactionBar主题，Toolbar应该与ContentView分开。 2.参考源码,base_layout的结构可以是LinearLayout里面一个ViewStub(生成toolbar),一个Framlayout(ContentVIew). 3.一个快速开发框架，应该有默认的模板，默认的样式。 4.Toolbar属于View范围，初始化应该在View里面，而不是在Presenter 5.参考AppCompatDelegate实现，提供多种默认的layout，根据layout生成不同的Toolbar。 6.继承BaseActivity,可以通过复写方法，控制是否需要Toolbar，以及自定义Toolbar。 7.ContentView应该使用Framlayout，可以被自由改造，比如：loadingView。。 8,参考AppCompatDelegate,具体实现使用ToolbarHelper的实现类,来代理创建设置Toolbar….BaseActivity不需要去关心这个过程.

来张丑丑的图:

新增的类:

UIView:

界面View,尽量让Frgament与Activity之间的切换,变的方便.只需改动极少的代码就能进行切换 Presenter,可以通过ToolbarHelper,控制Toolbar进行一些通用的设置.

ToolbarHelper

包含一些通用方法,如:getToolbar,setTitle,通过静态方法Create()传入不同的toolbarLayout的id,返回不同的实现类.

DefuatlToolbarHelperImplV1

默认的Toolbar实现.继承BaseToolBarHelperImpl

BaseToolBarHelperImpl

继承ToolbarHelper,否则创建toolbar,如果使用默认布局,则通过ViewStub 创建,如果使用自定义布局,则直接findview获取toolbar.

具体代码:

UIView:

package com.baozi.mvpdemo.ui.view;import android.app.Activity;import android.content.res.Resources;import android.support.v4.app.Fragment;import android.support.v7.app.ActionBar;import android.support.v7.widget.Toolbar;import android.view.View;/** * Created by baozi on 2017/2/20. * 用户页面,操作页面，对应Activity,frgament... */public interface UIView extends BaseView { /** * id查找控件 * 省去findviewById的强转操作 * * @param viewId 控件id * @param <V> 控件类型 * @return V extends View */ <V extends View> V findView(int viewId); /** * res资源获取 * * @return */ Resources getResources(); /** * 回退 */ void onBack(); /** * 是否自定义布局 * * @return */ boolean isCustomLayout(); /** * 是否使用MaterialDesign风格 * * @return */ boolean isMaterialDesign(); /** * MaterialDesign风格,普通风格之间转换 * * @param isMaterialDesign */ void setMaterialDesignEnabled(boolean isMaterialDesign); /** * 获取Acitivity * * @return */ Activity getActivity(); /** * Frgament跳转. * * @param tofragment */ void startFragment(Fragment tofragment); /** * Frgament跳转. * * @param tofragment */ void startFragment(Fragment tofragment, String tag); /** * 获得getSupportActionBar * * @return */ ActionBar getSupportActionBar(); /** * 设置getSupportActionBar * * @param toolbar * @return */ void setSupportActionBar(Toolbar toolbar); /** * 获得ToolbarHelper,Presenter可以通过ToolbarHelper的来控制toolbar */ ToolbarHelper getToolbarHelper();}

BaseActivity的变化

public abstract class BaseActivity<T extends BasePresenter> extends AppCompatActivity implements BaseActivityView { protected T mPresenter; protected SparseArray<View> mViews; private ToolbarHelper mToolbarHelper; private boolean isMaterialDesign; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mViews = new SparseArray<>(); //创建presenter mPresenter = initPresenter(); //绑定Activity mPresenter.onAttch(this); //是否完全自定义layout if (isCustomLayout()) { initContentView(LayoutInflater.from(this), savedInstanceState); } else { super.setContentView(R.layout.activity_base); //创建contentView View view = initContentView(LayoutInflater.from(this), savedInstanceState); //添加contentView FrameLayout base_content = findView(R.id.base_content); if (view != null) { //交给Persenter去扩展 mPresenter.initContentView(base_content, view); } //创建toolbar createToolbar(); } mPresenter.onCreate(); Looper.myQueue().addIdleHandler(new MessageQueue.IdleHandler() { @Override public boolean queueIdle() { mPresenter.LoadData(); return false; } }); } //复写setContentView,如果不设置完全自定义布局,则不能调用setContentView()方法. @Override public void setContentView(@LayoutRes int layoutResID) { //是否完全自定义布局,也就是不使用base_layout if (isCustomLayout()) { super.setContentView(layoutResID); } else { throw new IllegalStateException("please setting Presenter Method isCustomLyout() return true "); } } ...... /** * 通过viewId获取控件 * * @param viewId 资源id * @return */ @Override public <V extends View> V findView(@IdRes int viewId) { View view = mViews.get(viewId); if (view == null) { view = findViewById(viewId); mViews.put(viewId, view); } return (V) view; }}
