Android分享-微信、Facebook、Google1.引入分享库：2.微信分享：在项目包名下新建包，新建包名必须为

1.引入分享库：

implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:5.1.4'
implementation 'com.facebook.android:facebook-share:[4,5)',{
    exclude group: 'com.google.zxing', module: 'core'
}
implementation 'com.google.android.gms:play-services-plus:15.0.1'

2.微信分享：

在项目包名下新建包，新建包名必须为：wxapi wxapi包名下新建类：WXEntryActivity 分享回调处理在WXEntryActivity中，具体内容如下： /**

Created by Chao 2018/7/20 on 11:05
description 微信SDK回调路径 */ class WXEntryActivity : AppCompatActivity(), IWXAPIEventHandler {

override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) WXAPIFactory.createWXAPI(this, App.APP_ID, false).handleIntent(intent, this); }

/**
- 微信发送请求到第三方应用时，会回调到该方法 */ override fun onReq(p0: BaseReq?) { }
/**
- 第三方应用发送到微信的请求处理后的响应结果，会回调到该方法
- app发送消息给微信，处理返回消息的回调 */ override fun onResp(resp: BaseResp) { when (resp.errCode) { BaseResp.ErrCode.ERR_AUTH_DENIED, BaseResp.ErrCode.ERR_USER_CANCEL -> { showToast("分享取消") finish() }
```
 BaseResp.ErrCode.ERR_OK -> finish()
```
  } } }

微信分享初始化： /**

class App : BaseApplication() {

override fun init() {
    registerWeChat(this)
}

/**
 * 注册微信分享
 */
private fun registerWeChat(context: Context) {
    api = WXAPIFactory.createWXAPI(context, APP_ID, true);
    api.registerApp(APP_ID);
}

companion object {
    lateinit var api: IWXAPI
    const val APP_ID = "wx88888888"
    fun getWXAPI(): IWXAPI {
        return api
    }
}

}

微信分享调起： /**

fun share(activity: AppCompatActivity) { CommonShareDialog.show(activity, R.layout.common_dialog_share_chinese) { val webpage = WXWebpageObject() webpage.webpageUrl = "www.baidu.com"

     val msg = WXMediaMessage(webpage)
     msg.title = "标题"
     msg.description = "描述"
     //msg.thumbData = getWXThumb(bitmap).toByteArray()

     val req = SendMessageToWX.Req()
     //WXSceneTimeline朋友圈    WXSceneSession聊天界面
     req.scene = if (it == 0) SendMessageToWX.Req.WXSceneSession else SendMessageToWX.Req.WXSceneTimeline//0微信  1朋友圈
     req.message = msg
     req.transaction = System.currentTimeMillis().toString()
     App.getWXAPI().sendReq(req)
     if (it == 0) {//微信
         activity.showToast("微信")
     } else if (it == 1) {//朋友圈
         activity.showToast("朋友圈")
     }
 }

}

fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { } }

2.facebook、google+分享：

/**

fun share(activity: AppCompatActivity) { FacebookSdk.setApplicationId("217521058906811") FacebookSdk.sdkInitialize(activity.applicationContext) CommonShareDialog.show(activity, R.layout.common_dialog_share_international) { if (it == 0) {//facebook val content = ShareLinkContent.Builder() .setContentUrl(Uri.parse("developers.facebook.com")) .build() callbackManager = CallbackManager.Factory.create() val shareDialog = ShareDialog(activity) shareDialog.registerCallback(callbackManager, object : FacebookCallback<Sharer.Result> { override fun onCancel() { activity.showToast("分享取消") }

             override fun onSuccess(result: Sharer.Result?) {
                 activity.showToast("分享成功")
             }

             override fun onError(error: FacebookException?) {
                 activity.showToast("分享失败")
             }

         })
         shareDialog.show(content, ShareDialog.Mode.AUTOMATIC)
         //activity.showToast("facebook")
     } else if (it == 1) {//google
         val shareIntent = PlusShare.Builder(activity)
                 .setType("text/plain")      //  不变
                 .setText("Welcome to the Google+ platform.")   // 自定义内容
                 .setContentUrl(Uri.parse("https://developers.google.com/+/"))   // 自定义链接地址
                 .getIntent()
         try {
             activity.startActivityForResult(shareIntent, GOOGLE_REQUEST_CODE)
         } catch (e: ActivityNotFoundException) {
             activity.showToast("You haven't installed google+ on your device")
         }
         //activity.showToast("google+")
     }
 }

}

fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { if (requestCode == GOOGLE_REQUEST_CODE) {

     return
 }
 callbackManager?.onActivityResult(requestCode, resultCode, data)

} }
