效果图
功能实现
- 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;
public class CustomLogDelegate implements UILog.LogDelegate {
boolean isDebug = true;
@Override
public String getTag() {
return "日志Tag";
}
@Override
public UILog.LogDelegate init() {
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) {
}
@Override
public void i(String tag, String msg, Object... obj) {
}
@Override
public void w(String tag, String msg, Object... obj) {
}
@Override
public void e(String tag, String msg, Object... obj) {
}
@Override
public void xml(String tag, String msg) {
}
@Override
public void json(String tag, String msg) {
}
@Override
public void printErrStackTrace(String tag, Throwable throwable, Object... obj) {
}
}
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);
- 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);
- 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
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));
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
<meta-data
android:name="MVPArch.LCEDelegate"
android:value="com.littlejerk.mvparch.util.CustomLCEDelegate" />
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;
public class CustomLCEDelegate implements ILCEView {
private Context mContext = null;
private View mRealRootView = null;
private LoadingHelper mLoadingHelper = null;
private KProgressHUD mKProgressHUD = null;
public CustomLCEDelegate(View rootView) {
mContext = rootView.getContext();
mLoadingHelper = new LoadingHelper(rootView);
mRealRootView = mLoadingHelper.getDecorView();
}
@Override
public View getRealRootView() {
return mRealRootView;
}
@Override
public void setTitleBar(ITitleView titleParam) {
mLoadingHelper.register(ViewType.TITLE, new TitleBarAdapter(titleParam));
mLoadingHelper.setDecorHeader(ViewType.TITLE);
}
@Override
public void stateEmptyView() {
mLoadingHelper.showEmptyView();
}
@Override
public void stateErrorView() {
mLoadingHelper.showErrorView();
}
@Override
public void stateLoadingView() {
mLoadingHelper.showLoadingView();
}
@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();
}
@Override
public void loadingDialogShow(String msg, boolean cancelable, JSONObject extraData) {
}
@Override
public void loadingDialogDismiss() {
if (mKProgressHUD != null && mKProgressHUD.isShowing()) {
mKProgressHUD.dismiss();
}
}
@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
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
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());
}
@Override
protected void doBusiness(Bundle savedInstanceState) {
stateLoadingView();
HttpUtils.requestNet(this, new NetCallback<Long>() {
@Override
public void onSuccess(Long aLong) {
stateContentView();
}
@Override
public void onFailure(String msg) {
stateErrorView();
UIToast.showShort(msg);
}
});
}
}

- 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
public class AContract {
public interface MyActivityModel {
void requestNet(NetCallback<Long> netCallback);
}
public interface MyActivityView extends IView {
void showToast();
}
public interface MyActivityPresenter {
void loadData();
default void onReload() {
}
}
}
P层实现
public class MvpDemoActivityPresenter extends BasePresenter<MvpDemoActivityModel, AContract.MyActivityView>
implements AContract.MyActivityPresenter {
private static final String TAG = "MvpDemoActivityPresenter";
@Override
public void loadData() {
getV().stateLoadingView();
getM().requestNet(new NetCallback<Long>() {
@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<Long>() {
@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);
}
@Override
public void onDestroy(@NonNull LifecycleOwner owner) {
super.onDestroy(owner);
UILog.d(TAG, TAG + " onDestroy被调用");
}
}
V层实现
public class MvpDemoActivity extends BaseMVPActivity<MvpDemoActivityPresenter> 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
public class MvpDemoActivityModel extends BaseModel implements AContract.MyActivityModel {
@Override
protected void initData() {
UIToast.showLong("测试TestModel");
}
@Override
public void requestNet(NetCallback<Long> netCallback) {
Observable.timer(2, TimeUnit.SECONDS)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<Long>() {
@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!!!
