功能实现
  1. UILog、UIToast
框架默认实现了UILog、UIToast的代理UILogDelegate、UIToastDelegate,如果不满足需求,可实现自己定义的代理(实现UILog.LogDelegate、UIToast.ToastDelegate即可),具体可参考框架的实现,这里简单实现了CustomLogDelegate
package com.littlejerk.mvparch.util; import android.util.Log; import com.littlejerk.library.manager.MVPArchConfig; import com.littlejerk.library.manager.log.UILog; /** * @author : HHotHeart * @date : 2021/9/24 10:01 * @desc : 自定义代理 */ public class CustomLogDelegate implements UILog.LogDelegate {boolean isDebug = true; @Override public String getTag() {return "日志Tag"; }@Override public UILog.LogDelegate init() {//做一些初始化工作,如log日志的开关 isDebug = MVPArchConfig.getInstance().isLoggable(); return this; }@Override public void v(String tag, String msg, Object... obj) {if (isDebug) {Log.v(tag, msg); } }@Override public void d(String tag, String msg, Object... obj) {//自己的Log库 }@Override public void i(String tag, String msg, Object... obj) {//自己的Log库 }@Override public void w(String tag, String msg, Object... obj) {//自己的Log库}@Override public void e(String tag, String msg, Object... obj) {//自己的Log库}@Override public void xml(String tag, String msg) {//自己的Log库}@Override public void json(String tag, String msg) {//自己的Log库}@Override public void printErrStackTrace(String tag, Throwable throwable, Object... obj) {//自己的Log库} }

然后在Application中将代理设置给UILog
UILog.setDelegate(new CustomLogDelegate().init());

Log日志开关可通过MVPArchConfig配置
MVPArchConfig.getInstance().setLoggable(BuildConfig.DEBUG)

Toast的代理设置也一样,如
UIToast.setDelegate(UIToast.ToastDelegate delegate);

  1. EventManager、ILFactory
框架默认实现了EventBusImpl事件通知和GlideLoader图片加载器,可以自由切换(实现IEventBus、IImageLoader接口即可),实现了之后可通过MVPArchConfig配置,如替换GlideLoader
MVPArchConfig.getInstance().setImageLoader(IImageLoader imageLoader)

两者调用方式
EventManager.getBus().post(IEventBus.AbsEvent event); ILFactory.getLoader().loadNet(ImageView target, String url, IImageLoader.HOptions options);

  1. LCE-T
框架实现了L(加载视图)、C(内容视图)、E(错误视图、空视图)、T(标题)的逻辑处理,这里主要使用了两个库LoadingHelper和TitleBar ,具体实现原理可去Github上看看,框架可全局配置LCE-T,如
//设置状态栏颜色、标题属性 MVPArchConfig.getInstance() .setLightStatusBar(false) .setStatusBarColor(Color.BLACK) .setTitleParam(new TitleParam() .setLeftIcon(R.drawable.ic_arrow_back_black) .setMiddleTextSize(17f) .setMiddleTextColor(Color.BLACK) .setTitleBarHeight(R.dimen.title_bar_height) .setTittleBarBgColor(Color.WHITE) .setRightIconVisible(false) .setBottomLineColor(Color.LTGRAY) .setBottomLineHeight(0.5f)); //设置全局LCE LoadingHelper.setDefaultAdapterPool(adapterPool -> {adapterPool.register(ViewType.LOADING, new GLoadingAdapter()); adapterPool.register(ViewType.ERROR, new GErrorAdapter()); adapterPool.register(ViewType.EMPTY, new GEmptyAdapter()); return Unit.INSTANCE; });

其中GLoadingAdapter、GErrorAdapter、GEmptyAdapter是框架实现的默认全局LCE,可参考将其替换成自己项目的LCE。因为LCE-T的设置是通过LCEDelegate(实现ILCEView)实现的,要想改变代理实现,可自定义代理CustomLCEDelegate实现ILCEView接口,然后通过清单文件AndroidManifest.xml去配置自定义的代理,如

package com.littlejerk.mvparch.util; import android.content.Context; import android.text.TextUtils; import android.view.View; import com.dylanc.loadinghelper.LoadingHelper; import com.dylanc.loadinghelper.ViewType; import com.kaopiz.kprogresshud.KProgressHUD; import com.littlejerk.library.manager.lcet.ITitleView; import com.littlejerk.library.manager.lcet.TitleBarAdapter; import com.littlejerk.library.manager.lcet.ILCEView; import org.json.JSONObject; /** * @author : HHotHeart * @date : 2021/7/9 17:36 * @desc : 自定义LCE代理类,需在清单文件注册meta */ public class CustomLCEDelegate implements ILCEView {private Context mContext = null; private View mRealRootView = null; //加载中、加载失败、空布局视图 https://github.com/DylanCaiCoding/LoadingHelper private LoadingHelper mLoadingHelper = null; //加载框 https://github.com/Kaopiz/KProgressHUD private KProgressHUD mKProgressHUD = null; public CustomLCEDelegate(View rootView) {mContext = rootView.getContext(); mLoadingHelper = new LoadingHelper(rootView); mRealRootView = mLoadingHelper.getDecorView(); }/** * 获取真正的RootView * * @return */ @Override public View getRealRootView() {return mRealRootView; }/** * 设置标题 * 如果页面滑动对标题有动作,不建议使用LoadingHelper设置标题 * * @param titleParam */ @Override public void setTitleBar(ITitleView titleParam) {mLoadingHelper.register(ViewType.TITLE, new TitleBarAdapter(titleParam)); mLoadingHelper.setDecorHeader(ViewType.TITLE); }/** * 空数据视图 * 调用此方法确保mLoadingHelper注册对应的Adapter */ @Override public void stateEmptyView() {mLoadingHelper.showEmptyView(); }/** * 错误视图 * 调用此方法确保mLoadingHelper注册对应的Adapter */ @Override public void stateErrorView() {mLoadingHelper.showErrorView(); }/** * 加载中视图 * 调用此方法确保mLoadingHelper注册对应的Adapter */ @Override public void stateLoadingView() {mLoadingHelper.showLoadingView(); }/** * 显示内容视图 */ @Override public void stateContentView() {mLoadingHelper.showContentView(); }@Override public void loadingDialogShow() {loadingDialogShow(null); }@Override public void loadingDialogShow(boolean cancelable) {loadingDialogShow(null, cancelable); }@Override public void loadingDialogShow(String msg) {loadingDialogShow(msg, false); }@Override public void loadingDialogShow(String msg, boolean cancelable) {if (mKProgressHUD == null) {mKProgressHUD = KProgressHUD.create(mContext); } if (!TextUtils.isEmpty(msg)) {mKProgressHUD.setLabel(msg); } else {mKProgressHUD.setLabel(null); } mKProgressHUD.setCancellable(cancelable); mKProgressHUD.show(); }/** * 显示加载框的扩展 * * @param msg * @param cancelable * @param extraData拓展json字符串 */ @Override public void loadingDialogShow(String msg, boolean cancelable, JSONObject extraData) {}/** * 关闭加载框 */ @Override public void loadingDialogDismiss() {if (mKProgressHUD != null && mKProgressHUD.isShowing()) {mKProgressHUD.dismiss(); } }/** * 释放资源 */ @Override public void release() {mKProgressHUD = null; mContext = null; mLoadingHelper = null; mRealRootView = null; }public LoadingHelper getLoadingHelper() {return mLoadingHelper; }public KProgressHUD getKProgressHUD() {return mKProgressHUD; } }

其中KProgressHUD 的加载框可改变,LoadingHelper不可更改(LCE的实现原理)。如果是页面定制化,应该如何呢?比如我们的标题
/** * @Author : HHotHeart * @Time : 2021/8/14 15:42 * @Description : 标题属性Demo */ public class TitleDemoActivity extends BaseActivity {@Override protected void initContentView(@Nullable Bundle savedInstanceState) {setContentView(R.layout.activity_title_demo, new TitleParam("Title Demo") .setRightText("完成").setRightTextColor(Color.RED).setRightTextSize(17f) .setOnTitleBarListener(new TitleParam.SimpleTitleBarListener() {@Override public void onLeftClick(View view) {finish(); }@Override public void onRightClick(View view) {UIToast.showShort("点击完成"); } })); }@Override protected void doBusiness(Bundle savedInstanceState) {ILFactory.getLoader().loadNet(findViewById(R.id.imageView1), "https://dss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=218024201,1599297029&fm=26&gp=0.jpg", IImageLoader.HOptions.defaultOptions()); } }

我们需要继承框架的BaseActivity,如果是MVP架构,可继承BaseMVPActivity(Fragment同理),页面的标题相关属性会覆盖全局配置的属性。当然,页面LCE的配置也是可覆盖全局配置的LCE,如
/** * @Author : HHotHeart * @Time : 2021/9/23 10:39 * @Description : 自定义加载布局Demo */ public class CustomLCEActivity extends BaseActivity {@Override protected void initContentView(@Nullable Bundle savedInstanceState) {setContentView(R.layout.activity_custom_lce, "自定义LCE"); }@Override public void doPreBusiness() {LoadingHelper loadingHelper = ((CustomLCEDelegate) getLCEDelegate()).getLoadingHelper(); loadingHelper.register(ViewType.LOADING, new CLoadingAdapter()); //loadingHelper.register(ViewType.ERROR, "自定义的错误布局"); //loadingHelper.register(ViewType.EMPTY, "自定义的空布局"); }@Override protected void doBusiness(Bundle savedInstanceState) {stateLoadingView(); HttpUtils.requestNet(this, new NetCallback() {@Override public void onSuccess(Long aLong) {stateContentView(); }@Override public void onFailure(String msg) {stateErrorView(); UIToast.showShort(msg); } }); } }

  1. MVP模式
框架简易封装了MVP架构,使用了lifecycle管理Activity、Fragment和P层的生命周期,使用RxLifecycle管理Rxjava和Activity、Fragment的生命周期,有效地避免内存泄漏和P层销毁,延时任务造成的空指针问题,Activity(Fragment同理)业务逻辑实现的AContract管理MVP契约类
/** * @author : HHotHeart * @date : 2021/8/14 11:50 * @desc : 描述 */ public class AContract {public interface MyActivityModel {void requestNet(NetCallback netCallback); }public interface MyActivityView extends IView {void showToast(); }public interface MyActivityPresenter {void loadData(); default void onReload() {} } }

P层实现
/** * @Author : HHotHeart * @Time : 2021/6/11 11:53 * @Description : Activity Presenter */ public class MvpDemoActivityPresenter extends BasePresenter implements AContract.MyActivityPresenter {private static final String TAG = "MvpDemoActivityPresenter"; @Override public void loadData() {getV().stateLoadingView(); getM().requestNet(new NetCallback() {@Override public void onSubscribe(Disposable d) {getV().addDispose(d); }@Override public void onSuccess(Long o) {getV().stateContentView(); getV().showToast(); }@Override public void onFailure(String msg) {getV().stateErrorView(); UIToast.showShort(msg); } }); }@Override public void onReload() {getV().stateLoadingView(); getM().requestNet(new NetCallback() {@Override public void onSubscribe(Disposable d) {getV().addDispose(d); }@Override public void onSuccess(Long aLong) {getV().stateContentView(); }@Override public void onFailure(String msg) {getV().stateErrorView(); UIToast.showShort(msg); } }); }@Override public void onResume(@NonNull @NotNull LifecycleOwner owner) {super.onResume(owner); }/** * BasePresenter实现了和Activity或Fragment生命周期绑定,重写即可 * * @param owner */ @Override public void onDestroy(@NonNull LifecycleOwner owner) {super.onDestroy(owner); UILog.d(TAG, TAG + " onDestroy被调用"); }}

V层实现
/** * @Author : HHotHeart * @Time : 2021/8/14 15:09 * @Description : Activity MVP例子 */ public class MvpDemoActivity extends BaseMVPActivity implements AContract.MyActivityView {private static final String TAG = "MvpDemoActivity"; @BindView(R.id.imageView1) ImageView mImageView1; @Override protected void initContentView(@Nullable Bundle savedInstanceState) {setContentView(R.layout.activity_test_mvp, new TitleParam("Activity MVP模式")); }@Override protected void doBusiness(Bundle savedInstanceState) {ILFactory.getLoader().loadNet(mImageView1, "https://dss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=218024201,1599297029&fm=26&gp=0.jpg", IImageLoader.HOptions.defaultOptions()); findView(R.id.btn_test, v -> UIToast.showLong("测试Toast")); UILog.e(TAG, "isVisible:" + isVisible(findView(R.id.btn_test))); getP().loadData(); }@Override public void showToast() {UIToast.showLong("loadData加载完成"); }}

M层实现
/** * @Author : HHotHeart * @Time : 2021/6/11 15:46 * @Description : 描述 */ public class MvpDemoActivityModel extends BaseModel implements AContract.MyActivityModel {@Override protected void initData() {UIToast.showLong("测试TestModel"); }@Override public void requestNet(NetCallback netCallback) {Observable.timer(2, TimeUnit.SECONDS) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Observer() {@Override public void onSubscribe(@NonNull Disposable d) {if (netCallback != null) {netCallback.onSubscribe(d); } }@Override public void onNext(@NonNull Long aLong) {if (netCallback != null) {netCallback.onSuccess(aLong); } }@Override public void onError(@NonNull Throwable e) {if (netCallback != null) {netCallback.onFailure(e.getMessage()); } }@Override public void onComplete() {UILog.e("onComplete()"); } }); } }

BaseActivity和BaseFragment实现了Disposable的管理,每执行一个Rxjava任务时,应手动调用方法
getV().addDispose(d);

添加任务的Disposable,在页面销毁时会把任务中断。除此之外还可以调用
observable.compose(bindUntilEvent(ActivityEvent event));

将Rxjava任务与页面生命周期绑定,ActivityEvent对应Actiivity的生命周期,如ActivityEvent.DESTROY,具体可查看RxLifecycle的用法。
后续会实现网络请求相关模块,将其请求与页面和Presneter生命周期完美结合起来,敬请期待!!!
