Question

创建了一个imagebutton：facebook图标和twitter图标。因此，当用户点击任一图标时，它将分别调用新意图;因此，如果用户点击了facebook图标，它将调用facebook.class的意图。

但是，当用户点击facebook图标或推特图标时，它没有响应，并且在同一方法中调用不同的意图。有人可以帮忙吗？感谢

设法破译了问题，并提出了一个可以调用次要意图的解决方案：

代码：

//DAPO-DEV02:20150107: Social Media Sharing: Twitter

final ImageButton TwitterBtn = (ImageButton) mContex.findViewById(R.id.twitter_icon);
TwitterBtn.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        String cKey = "MNjFvsNstiMXcddTLc4J0IsHa";
                        String cSecret = "NgziPWnykalqAeMZhDUygqAYS89qJtVsehv9aQhLSlZW2myZXp";
                        final String tw="";



                        if (shareTwitter == null)
                            shareTwitter = new ShareTwitter(cKey, cSecret, ((android.app.Activity) getActivity()),
                                    getActivity().getApplicationContext(), R.drawable.twitter_icon);

                        if (socialBgAsyncTask == null) {
                            socialBgAsyncTask = (SocialBgAsyncTask) new SocialBgAsyncTask();
                            socialBgAsyncTask.execute();

                                    i.setData(Uri.parse(twitterURL+Uri.encode(tw)));
                                    startActivity(i);
                                } catch (android.content.ActivityNotFoundException e){
                                    Toast.makeText(getActivity(), "Can't tweet", Toast.LENGTH_SHORT).show();
                                }

Answer 2

简单地替换

ImageView TwitterBtn = (ImageView) mContex.findViewById(R.id.twitter_icon);

与

ImageButton TwitterBtn = (ImageButton) mContex.findViewById(R.id.twitter_icon);

尽管图像按钮被初始化，但没有被调用
