android 微信第三方登录

compile 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:1.0.2'

在全局的application文件中的onCreate中添加registToWX()：

import com.tencent.mm.opensdk.openapi.IWXAPI;import com.tencent.mm.opensdk.openapi.WXAPIFactory;

public static IWXAPI mWxApi;private void registToWX() {//AppConst.WEIXIN.APP_ID是指你应用在微信开放平台上的AppID，记得替换。mWxApi = WXAPIFactory.createWXAPI(this, "*********", false);// 将该app注册到微信mWxApi.registerApp("***********");}

在调用页面的点击事件中加入：

case R.id.iv_wxLogin:wxLogin();break;

public void wxLogin() {if (!HaierApp.mWxApi.isWXAppInstalled()) {Toast.makeText(this,"您还未安装微信客户端",Toast.LENGTH_SHORT).show();return;}final SendAuth.Req req = new SendAuth.Req();req.scope = "snsapi_userinfo";req.state = "diandi_wx_login";HaierApp.mWxApi.sendReq(req);}

然后在包名.wxapi文件夹下增加WXEntryActivity文件：
