介绍：
项目地址：https://github.com/woaigmz/modularization/tree/master/sdk-share
组件化项目的sharelib，欢迎大家fork star 甚至 follow 感谢：）
造个轮子吧，用自己的心里踏实：
项目集成微信、QQ、微博。很烦，并不想用三方的一键分享。不如自己写个 sdk 吧，以后逻辑都要自己控制 ：）
代码设计：
1：单一职责原则 (Single Responsibility Principle, SRP) 一个类只负责一个功能领域中的相应职责
2：开闭原则 (Open-Closed Principle, OCP) 软件实体应对扩展开放，而对修改关闭
3：里氏代换原则 (Liskov Substitution Principle, LSP) 所有引用基类对象的地方能够透明地使用其子类的对象
4：依赖倒转原则 (Dependence Inversion Principle, DIP) 抽象不应该依赖于细节，细节应该依赖于抽象
5：接口隔离原则 (Interface Segregation Principle, ISP) 使用多个专门的接口，而不使用单一的总接口
6：合成复用原则 (Composite Reuse Principle, CRP) 尽量使用对象组合，而不是继承来达到复用的目的
7：迪米特法则 (Law of Demeter, LoD) 一个软件实体应当尽可能少地与其他实体发生相互作用
我的 share-sdk 层次：
share-sdk
分析：
view层：
dialog(一般情况下的分享弹窗)，
ShareActivity(隔离层，中间件，分离组合三种分享回调)
model层：
AppId(三个平台注册的appid,实现了Serializable)
ShareBean(存放分享内容，实现了Parcelable)
presenter层：
通过分享类型，分享model的数据，来调起 view（ShareActivity） 进而调起 SDK (QQShare/WXShare/SineShare)
proxy:
提供sdk入口：初始化appid，创建分享dialog，设置点击监听 ，其他功能可根据情况扩展
其他:
util：缩略图的异步加载优化并进行dislrucache，序列化id等工具
@IntDef注解：性能优于class和枚举，将分享渠道和状态从代码里分离，解耦
share：将分享功能sdk处理调用放在这里
ShareListener：将三种sdk回调在ShareActivity处理
wxapi/WXEntryActivity：通过WXShare.sendBroadcast(this, resp.errCode)将分享的回调发送广播传递给WXShare的广播接收者，收到回调结果传给ShareListener(WXShare的WXShareReceiver注册在ShareActivity里)
使用：
1: Application 里
（这些id先用美团的吧，注意替换自己的）
ShareSdkProxy.getInstance().init(this,new String[]{"214506","wxa552e31d6839de85","1550938859"});
2: 自己的 Fragment 或 Acitvity 里
创建 分享视图
//创建 dialog
IShareView shareDialog = ShareSdkProxy.getInstance().createShareDialog(new int[]{ShareChannel.CHANNEL_QQ, ShareChannel.CHANNEL_WEIBO, ShareChannel.CHANNEL_WECHAT_MOMENT, ShareChannel.CHANNEL_QQ_ZONE}, 4);
// 设置点击回调和数据
ShareSdkProxy.getInstance().setOnShareClickListener(shareDialog, getActivity(), new ShareBean("分享了", "今天天气不错", "http://118.89.233.211:3000/images/1530106897838_.jpg", R.drawable.ic_launcher, "http://www.baidu.com"));
//展示 dialog
shareDialog.show(getFragmentManager());
3: 自己的 Fragment 或 Acitvity 里
接收回调结果
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
int status = data.getIntExtra(ShareActivity.RESULT_STATUS, -1);
switch (status) {
case ShareStatus.SHARE_STATUS_COMPLETE:
ToastUtil.showShortToast("分享成功");
break;
case ShareStatus.SHARE_STATUS_ERROR:
ToastUtil.showShortToast("分享失败");
break;
case ShareStatus.SHARE_STATUS_CANCEL:
ToastUtil.showShortToast("取消分享");
break;
}
}
}
详情：
1：入口ShareSdkProxy
public class ShareSdkProxy implements IShareSdkProxy {
private ShareSdkProxy() {
}
public interface OnShareClickListener {
void onShareClick(@ShareChannel int channel);
}
private static class Holder {
private static final ShareSdkProxy IN = new ShareSdkProxy();
}
public static ShareSdkProxy getInstance() {
return Holder.IN;
}
@Override
public void init(Application app, String[] appIds) {
if (app != null && appIds != null && appIds.length == 3) {
try {
SerializeUtils.serialization(getSerializePath(app), new AppId(appIds[0], appIds[1], appIds[2]));
} catch (Exception e) {
throw new RuntimeException(" ShareSdk serialized error： " + e);
}
} else {
throw new RuntimeException(" ShareSdk init error ");
}
}
/**
* the channel turn can inflect the turn of IShareView( in this is a dialog )
*
* @param shareChannel the type of share function
* @param column the column of dialog
* @return the instance of dialog
* @link ShareChannel.java
*/
@Override
public IShareView createShareDialog(int[] shareChannel, int column) {
return ShareDialog.get().createShareDialog(shareChannel, column);
}
/**
* @param dialog dialog
* @param activity the current activity to accept the result of the share sdk
* @param shareBean the model of share function
*/
@Override
public void setOnShareClickListener(IShareView dialog, final Activity activity, final ShareBean shareBean) {
dialog.setOnShareClickListener(new OnShareClickListener() {
@Override
public void onShareClick(int channel) {
switch (channel) {
case ShareChannel.CHANNEL_WECHAT:
SharePresenter.start(activity).onShareWx(shareBean);
break;
case ShareChannel.CHANNEL_WECHAT_MOMENT:
SharePresenter.start(activity).onShareWxCircle(shareBean);
break;
case ShareChannel.CHANNEL_QQ:
SharePresenter.start(activity).onShareQQ(shareBean);
break;
case ShareChannel.CHANNEL_QQ_ZONE:
SharePresenter.start(activity).onShareQZone(shareBean);
break;
case ShareChannel.CHANNEL_WEIBO:
SharePresenter.start(activity).onShareWeiBo(shareBean);
break;
case ShareChannel.CHANNEL_MORE:
break;
case ShareChannel.CHANNEL_CANNEL:
break;
}
}
});
}
}
2：控制器：SharePresenter
控制model调起view（ShareActivity）
public class SharePresenter implements ISharePresenter {
private static volatile SharePresenter presenter = null;
public static ISharePresenter start(Activity activity) {
if (presenter == null) {
synchronized (SharePresenter.class) {
if (presenter == null)
presenter = new SharePresenter(activity);
}
}
return presenter;
}
private SharePresenter(Activity activity) {
this.context = new WeakReference<>(activity);
}
private void startActivityForResult(int type, ShareBean entry) {
Activity activity = context.get();
assert activity != null : " activity weak reference maybe a null object ";
activity.startActivityForResult(ShareActivity.getIntent(activity, entry, type), type);
}
private WeakReference<Activity> context;
@Override
public void onShareWeiBo(ShareBean entry) {
startActivityForResult(ShareChannel.CHANNEL_WEIBO, entry);
}
@Override
public void onShareWxCircle(ShareBean entry) {
startActivityForResult(ShareChannel.CHANNEL_WECHAT_MOMENT, entry);
}
@Override
public void onShareWx(ShareBean entry) {
startActivityForResult(ShareChannel.CHANNEL_WECHAT, entry);
}
@Override
public void onShareQQ(ShareBean entry) {
startActivityForResult(ShareChannel.CHANNEL_QQ, entry);
}
@Override
public void onShareQZone(ShareBean entry) {
startActivityForResult(ShareChannel.CHANNEL_QQ_ZONE, entry);
}
}
3：隔离者，中间件：
ShareActivity（背景透明），处理分享逻辑
1:初始化appid和分享type以及share的数据
2:通过type 初始化 sdk
3:处理sdk回调，成功、失败、取消，因微信分享没有提供listener，所以在wxapi下发送广播send回调response，ShareActivity注册广播接收者，接收回调信息
4:回调完成，不管什么结构都要finish这个中间件，见finishWithResult方法
public class ShareActivity extends Activity implements WbShareCallback, ShareListener {
private static final String SHARE_ENTRY = "ShareBean";
private static final String SHARE_CHANNEL = "ShareChannel";
public static final String RESULT_CHANNEL = "result_channel";

@Override
public void onWbShareSuccess() {
onShareSuccess();
}
@Override
public void onWbShareCancel() {

}
@Override
public void onWbShareFail() {
onShareFail();

@Override

}
}
4：share目录下分享sdk调用
，QQShare、WXShare、SineShare，只举一个吧
WXShare：（通过flag判断微信好友还是朋友圈）
1：将 ShareBean 的数据添加到 SDK 的调用
2：处理图片
3：因没有 回调的listener，提供广播
public class WXShare {

5：Dialog
1:DialogFragment
2:setArguments传递参数
3:recyclerview 实现 ui 显示

使用可以直接下载下library
api project(':sdk-share')
可自己根据实际项目ui、逻辑调整
