安卓微信登陆

1、单击登陆图片按钮  LoginActivity

   private IWXAPI mWeixinAPI;   public void loginMsgChat(){        if (mWeixinAPI == null) {            mWeixinAPI = WXAPIFactory.createWXAPI(this, AppID, false);        }        if (!mWeixinAPI.isWXAppInstalled()) {            Toast.makeText(context, "请安装微信", Toast.LENGTH_SHORT).show();            return;        }        mWeixinAPI.registerApp(AppID);        SendAuth.Req req = new SendAuth.Req();        req.scope = "snsapi_userinfo";        req.state =  "wechat_sdk_gushen";;        mWeixinAPI.sendReq(req);        }

2、微信客户端回调 WXEntryActivity

    WXEntryActivity extends Activity implements IWXAPIEventHandler    private IWXAPI api;    protected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);api = WXAPIFactory.createWXAPI(this, Content.MSG_APPID, false);api.registerApp(Content.MSG_APPID);api.handleIntent(getIntent(), this);}    @Override    public void onReq(BaseReq arg0) {// TODO Auto-generated method stub}    @Override    public void onResp(BaseResp arg0) {// TODO Auto-generated method stubint result = 0;switch (arg0.errCode) {case BaseResp.ErrCode.ERR_OK:result = R.string.errcode_success;sendAuthResp = (SendAuth.Resp) arg0;handler.sendEmptyMessage(2);break;case BaseResp.ErrCode.ERR_USER_CANCEL:result = R.string.errcode_cancel;break;case BaseResp.ErrCode.ERR_AUTH_DENIED:result = R.string.errcode_deny;break;default:result = R.string.errcode_unknown;break;}finish();}    private Handler handler = new Handler(Looper.myLooper()) {public void handleMessage(Message msg) {switch (msg.what) {case 11:Intent intent = new Intent(WXEntryActivity.this,LoginActivity.class);HashMap<String, Object> j1 = (HashMap<String, Object>) msg.obj;Bundle bundle = new Bundle();bundle.putString("thirdid", j1.get("openid").toString());bundle.putString("fromConnect", "" + 3);bundle.putString("nameConnect", j1.get("nickname").toString());bundle.putString("headimgurl", j1.get("headimgurl").toString());intent.putExtras(bundle);startActivity(intent);break;case 2:new Thread1().start();break;case 3:new Thread2().start();break;default:break;}}};    public void WeiAT() {     String url_constant1 = "https://api.weixin.qq.com/sns/oauth2/access_token?appid="+ Content.MSG_APPID+ "&secret="+ Content.MSG_AppSecret+ "&code="+ sendAuthResp.token+ "&grant_type=authorization_code";    }    public void WeiGeren() {     String url_constant2 = "https://api.weixin.qq.com/sns/userinfo?access_token="+ ACCESS_TOKEN + "&openid=" + OPENID;             Message message = new Message();     message.what = 11;     message.obj = hm;     handler.sendMessage(message);}

3、 返回Bundle      LoginActivity

    @Overrideprotected void onNewIntent(Intent intent) {// TODO Auto-generated method stubsuper.onNewIntent(intent);setIntent(intent);Bundle bundle=new Bundle();bundle=intent.getExtras();if(bundle!=null){String s1=bundle.getString("thirdid");String s2=bundle.getString("fromConnect");String s3=bundle.getString("nameConnect");photoUrl = bundle.getString("headimgurl");thirdPair.clear();thirdPair.add(new BasicNameValuePair("thirdid",s1));thirdPair.add(new BasicNameValuePair("fromConnect", s2));thirdPair.add(new BasicNameValuePair("nameConnect", s3));接着是第三方登录接口}}
