微博API只能出来登陆界面但是发微博界面出不来

我想要在软件里面加个按钮点击一下可以发微博，但是从微博API的DEMO拷了代码过来不知道为什么点了之后可以出来登陆界面，但是登陆后不会转到发微博的界面，登陆后再点按钮就没有反应了LOGCAT也没半点信息出来ORZ

代码如下

public class ContrastActivity extends Activity implements OnClickListener,
		IWeiboHandler.Response {

	private static final String TAG = "ContrastActivity";

	public static final String KEY_SHARE_TYPE = "key_share_type";
	public static final int SHARE_CLIENT = 1;
	public static final int SHARE_ALL_IN_ONE = 2;
	// private Button mSharedBtn;

	private LinearLayout mSharedBtn;
	private IWeiboShareAPI mWeiboShareAPI = null;

	private int mShareType = SHARE_CLIENT;
 protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.con_activity);

		initViews();


		mShareType = getIntent().getIntExtra(KEY_SHARE_TYPE, SHARE_CLIENT);

		mWeiboShareAPI = WeiboShareSDK.createWeiboAPI(this, Constants.APP_KEY);

		mWeiboShareAPI.registerApp();

		if (savedInstanceState != null) {
			mWeiboShareAPI.handleWeiboResponse(getIntent(), this);
		}

	}

	@Override
	protected void onNewIntent(Intent intent) {
		super.onNewIntent(intent);

		mWeiboShareAPI.handleWeiboResponse(intent, this);
	}

	@Override
	public void onResponse(BaseResponse baseResp) {
		switch (baseResp.errCode) {
		case WBConstants.ErrorCode.ERR_OK:

			break;

			break;
