PYBase
Android基础项目，封装了BaseActivity、BaseFragment、BaseLazyFragment，使用MVP设计模式、RxJava + Retrofit作为网络框架，目前处于初步阶段，项目会逐步进行更新
记录自己学到的东西
MVP+RxJava+Retrofit的封装
首先是RetrofitService：
/**
* 登录
*/
@GET("login/{param}")
Observable<BaseResponse<User>> login(@Path("param") String param,
@Query("password") String password,
@Query("userType") int userType,
@Query("visitIp") String ip);
retrofit配合rxjava使用需要将login()返回类型从原来的Call<T>类型改为Observable<T>类型
BaseResponse：
class BaseResponse<T> {
private String msg;
private int code;
private T data;
}
接着是RetrofitUtils得到Retrofit实例：
public static Retrofit getInstance(String url) {
sRetrofit = new Retrofit.Builder().baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.client(getClient())
.build();
return sRetrofit;
}
private static OkHttpClient getClient() {
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.retryOnConnectionFailure(true).connectTimeout(TIMEOUT_CONNECT, TimeUnit.SECONDS)
.readTimeout(TIMEOUT_CONNECT, TimeUnit.SECONDS);
if (L.getGlobalToggle()) // 控制是否需要打印调试
builder.addInterceptor(new LogInterceptor());
return builder.build();
}
接下来就是MVP的使用：
首先是一些基类：
IView：
public interface IView<T extends IPresenter> {
/**
* 设置presenter
* @param presenter
*/
void setPresenter(T presenter);
/**
* 显示加载动画
*/
void showLoading();
/**
* 隐藏加载
*/
void hideLoading();
/**
* 显示错误状态
*/
void showError(StateLayout.OnRetryListener onRetryListener);
/**
* 显示提示
*/
void showTip(String tip);
}
BasePresenter：
public class BasePresenter<M extends IModel, V extends IView> implements IPresenter {
protected CompositeDisposable mCompositeDisposable;
protected M mModel;
protected V mView;
public BasePresenter(String baseUrl, V view) {
this.mView = view;
}
protected void addDispose(Disposable disposable) {
if (mCompositeDisposable == null) {
mCompositeDisposable = new CompositeDisposable();
}
// 将所有disposable放入，集中处理
mCompositeDisposable.add(disposable);
}
@Override
public void onDestroy() {
unDispose();
if (mModel != null)
mModel.onDestroy();
this.mModel = null;
this.mView = null;
this.mCompositeDisposable = null;
}
/**
* 解除订阅
*/
protected void unDispose() {
if (mCompositeDisposable != null) {
// 保证activity结束时取消所有正在执行的订阅
mCompositeDisposable.clear();
}
}
}
BaseModel获取RetrofitService实例：
public class BaseModel implements IModel {
protected ApiService mService;
public BaseModel(String baseUrl) {
mService = RetrofitUtils.getInstance(baseUrl).create(ApiService.class);
}
@Override
public void onDestroy() {
mService = null;
}
ILoginContract：
public interface ILoginContract {
interface Presenter extends IPresenter {
/**
* 登录
*/
void login(String param, String password, int userType, String ip);
}
interface View extends IView<Presenter> {
/**
* 获取登录信息
* @param user
*/
void showLoginMsg(User user);
}
}
LoginModelImpl省略...
LoginPresenter：
public class LoginPresenter extends BasePresenter<LoginModelImpl, ILoginContract.View> implements ILoginContract.Presenter {
public LoginPresenter(String baseUrl, ILoginContract.View view) {
super(baseUrl, view);
mModel = new LoginModelImpl(Constant.BASE_URL);
mView.setPresenter(this);
}
@Override
public void login(String param, String password, int userType, String ip) {
ModelFilteredFactory.compose(mModel.login(param, password, userType, ip))
.compose(RxUtils.bindToLifecycle(mView))
.subscribe(new BaseObserver<User>() {
@Override
protected void onHandleSuccess(User user) {
mView.showLoginMsg(user);
}
@Override
protected void onHandleError(String tip) {
mView.showTip(tip);
}
});
}
}
其中使用了RxLifecycle绑定了activity和fragment的生命周期，防止rxjava使用过程当中的内存泄漏(生命周期的解除订阅)
public static <T> LifecycleTransformer<T> bindToLifecycle(IView view) {
if (view instanceof RxAppCompatActivity) {
return ((RxAppCompatActivity) view).bindToLifecycle();
} else if (view instanceof RxFragment) {
return ((RxFragment) view).bindToLifecycle();
} else {
throw new IllegalArgumentException("view isn't activity or fragment");
}
}
BaseObserver(简单封装了Observer)：
@Override
public void onNext(@NonNull BaseResponse<T> response) {
if (response.getCode() == Constant.RESPONSE_CODE_OK) {
T data = response.getData();
onHandleSuccess(data);
} else {
onHandleError(response.getMsg());
}
}
@Override
public void onError(Throwable e) {
L.e("error:" + e.toString());
if (e instanceof APIException) {
APIException exception = (APIException) e;
onHandleError(exception.getMessage());
} else if (e instanceof UnknownHostException) {
onHandleError("请打开网络");
} else if (e instanceof SocketTimeoutException) {
onHandleError("请求超时");
} else if (e instanceof ConnectException) {
onHandleError("连接失败");
} else if (e instanceof HttpException) {
onHandleError("请求超时");
} else {
onHandleError("请求失败");
}
e.printStackTrace();
}
在activity(封装了BaseActivity简化代码)中使用：
public class MainActivity extends BaseActivity<ILoginContract.Presenter> implements ILoginContract.View
mPresenter = new LoginPresenter(Constant.BASE_URL, this);
发送网络请求就仅仅只需一行代码：
mPresenter.login("用户名", "123456", 0, "");
在showLoginMsg()中返回服务器返回的信息：
@Override
public void showLoginMsg(User user) {
// DO SOMETHING
}
RecyclerView.Adapter的简单封装：
- 极大简化了代码
- 支持添加多个Header和Footer
- 支持item的单击和长按监听
- 支持RecyclerView多ViewType
- RecyclerView数据源变动的封装
- RecyclerView列表的单选和多选模式
使用方法：
class PYAdapter extends BaseRvAdapter<String> {
public PYAdapter(Context context, List<String> dataList, int layoutId) {
super(context, dataList, layoutId);
}
@Override
public void convert(BaseViewHolder holder, String item, int position, int viewType) {
holder.setText(R.id.tv, item);
}
}
rc.setAdapter(new PYAdapter(this, dataList, R.layout.item));
多布局使用方法：
class PYAdapter extends BaseRvAdapter<String> {
public PYAdapter(Context context, List<String> dataList, IMultiItemViewType<String> multiItemViewType) {
super(context, dataList, multiItemViewType);
}
@Override
public void convert(BaseViewHolder holder, String item, int position, int viewType) {
switch (viewType) {
case 100:
holder.setText(R.id.tv, item + " 100");
break;
case 200:
holder.setText(R.id.tv, item + " 200");
break;
}
}
}
PYAdapter pyAdapter = new PYAdapter(this, dataList, new IMultiItemViewType<String>() {
@Override
public int getItemViewType(int position, String s) {
if (position % 2 == 0) {
return 100;
} else {
return 200;
}
}
@Override
public int getLayoutId(int viewType) {
return R.layout.item;
}
});
rv.setAdapter(pyAdapter);
添加Header/Footer(支持多Header/Footer)：
View headerView0 = LayoutInflater.from(this).inflate(R.layout.item, null);
View headerView1 = LayoutInflater.from(this).inflate(R.layout.item, null);
View footerView0 = LayoutInflater.from(this).inflate(R.layout.item, null);
View footerView1 = LayoutInflater.from(this).inflate(R.layout.item, null);
pyAdapter.addHeaderView(headerView0, headerView1);
pyAdapter.addFooterView(footerView0, footerView1);
RecyclerView item单击和长按监听：
pyAdapter.setOnItemClickListener((holder, position, item) -> {});
pyAdapter.setOnItemLongClickListener((holder, position, item) -> {});
RecyclerView数据源变动的封装：
void add(T item);
void add(int position, T item);
void addAll(List<T> items);
void addAll(int position, List<T> items);
void remove(T item);
void remove(int position);
void removeAll(List<T> items);
void retainAll(List<T> items);
void set(T oldItem, T newItem);
void set(int position, T item);
void replaceAll(List<T> items);
void clear();
RecyclerView列表的单选和多选模式：
使用SelectAdapter(继承自BaseRvAdapter)
// 单选模式
selectAdapter.setSelectedMode(ISelect.SINGLE_MODE);
// 多选模式
selectAdapter.setSelectedMode(ISelect.MULTIPLE_MODE);
创建实体类实现ISelect接口：
public class TestSelectBean implements ISelect {
private boolean isSelected;
private String text;
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
@Override
public boolean isSelected() {
return isSelected;
}
@Override
public void setSelected(boolean selected) {
isSelected = selected;
}
}
创建SelectAdapter：
class PyAdapter extends SelectAdapter<TestSelectBean> {
public PyAdapter(Context context, List<TestSelectBean> dataList, int layoutId) {
super(context, dataList, layoutId);
}
@Override
public void convert(BaseViewHolder holder, TestSelectBean item, int position, int viewType) {
CheckBox cb = holder.getView(R.id.cb);
cb.setChecked(item.isSelected());
holder.setText(R.id.tv, item.getText());
}
}
设置选择模式下的监听：
mAdapter.setItemSelectedListener(new SelectAdapter.OnItemSelectedListener<TestSelectBean>() {
@Override
public void onItemSelected(BaseViewHolder viewHolder, int position, boolean isSelected, TestSelectBean testSelectBean) {
if (isSelected) {
// 如果被选中
} else {
// 如果没有被选中
}
}
@Override
public void onNothingSelected() {
// 什么也没有选中
}
});
封装BaseDialog，实现TitleDialog、BottomDialog、ListDialog(配合SelectAdapter实现单选、多选模式)
<img width="300" height="100" src="http://upload-images.jianshu.io/upload_images/1570601-4020c2cee50c77e3.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"/>
<img width="320" height="360" src="http://upload-images.jianshu.io/upload_images/1570601-6105f9934b4f003b.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"/><img width="320" height="360" src="http://upload-images.jianshu.io/upload_images/1570601-021004253263b075.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"/>
<img width="320" height="600" src="http://upload-images.jianshu.io/upload_images/1570601-e05e7c07786d0829.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"/>
使用方法：
TitleDialog：
new TitleDialog(this).setDialogTitle("标题")
.setLeftButtonText("取消")
.setRightButtonText("确定")
.setOnLeftBtnClickListener(null)
.setOnRightBtnClickListener((dialog, view) -> {
// do something
dialog.dismissDialog();
}).showDialog();
ListDialog(默认单选模式)：
ListDialog<MyAdapter, TestSelectBean> listDialog = new ListDialog<>(this);
listDialog.setSelectAdapter(new MyAdapter(this, dataList, R.layout.item), new SelectAdapter.OnItemSelectedListener<TestSelectBean>() {
@Override
public void onItemSelected(BaseViewHolder viewHolder, int position, boolean isSelected, TestSelectBean testSelectBean) {
if (isSelected) {
// 如果被选中
} else {
// 如果没有被选中
}
}
@Override
public void onNothingSelected() {
// 什么也没有选中
}
}).setSelectMode(ISelect.SINGLE_MODE).showDialog();
多选模式：
setSelectMode(ISelect.MULTIPLE_MODE)
BottomDialog：
new BottomDialog(this)
.setFullWidth()
.setFromBottom()
.setLeftButtonText("拍照")
.setRightButtonText("从相册中选择照片")
.setOnLeftBtnClickListener((dialog, view) -> {})
.setOnRightBtnClickListener((dialog, view) -> {})
.showDialog();
