登录facebook成功后如何打开活动？

Question

我有两项活动，当我登录facebook活动成功时。它将是自动打开活动2并传输数据和图片。但它不起作用。请帮我！ 问题是如何在授权成功登录facebook按钮后调用另一个活动并传输数据。我一直在阅读其他帖子，但没有解决方案可以帮助我。

活动

更改您的代码：

login.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                if(AccessToken.getCurrentAccessToken() != null){
                    RequestData();
                    share.setVisibility(View.VISIBLE);
                    details.setVisibility(View.VISIBLE);

                }
Intent intent=new Intent(MainActivity.this,Main2Activity.class);
        String emails=email.getText().toString();
        intent.putExtra("emails", emails);        
        intent.putExtra("BitmapImage", profile);
        startActivity(intent);
            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onError(FacebookException error) {
                Log.e(TAG, "onError: " + error.getMessage());
            }
        });



@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }

我希望这会奏效。

在activity方法中开始onSuccess。

login.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                if(AccessToken.getCurrentAccessToken() != null){
                    RequestData();
                    share.setVisibility(View.VISIBLE);
                    details.setVisibility(View.VISIBLE);

                }
            }
