我在片段中的分享对话框中有以下代码:
TabFour.java
public class TabFour extends Fragment {
private UiLifecycleHelper uiHelper;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_tab_four, container, false);
return rootView;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(getActivity(), callback);
uiHelper.onCreate(savedInstanceState);
OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
action.setProperty("book", "https://example.com/book/Snow-Crash.html");
@SuppressWarnings("deprecation")
FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(getActivity(), action, "books.reads", "book")
.build();
uiHelper.trackPendingDialogCall(shareDialog.present());
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data, new FacebookDialog.Callback() {
@Override
public void onError(FacebookDialog.PendingCall pendingCall, Exception error, Bundle data) {
Log.e("Activity", String.format("Error: %s", error.toString()));
}
@Override
public void onComplete(FacebookDialog.PendingCall pendingCall, Bundle data) {
Log.i("Activity", "Success!");
}
});
}
@Override
public void onResume() {
super.onResume();
uiHelper.onResume();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
uiHelper.onSaveInstanceState(outState);
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
// TODO Auto-generated method stub
}
};
}
Facebok Share在模拟器上加载,但它不在手机上。此外,当共享对话框在模拟器上加载时,您无法共享它,因为左上角的共享按钮被禁用(可见但无法单击)。此外,模拟器显示一个Toast消息“无法获取共享预览”。请帮忙!
我希望有人可以向我解释一下。谢谢!

来自https://developers.facebook.com/docs/android/share
Facebook分享对话框仅在安装了facebook app时才有效。因此,建议的方法是首先检查是否可以显示共享对话框,如果可以显示,则将其与您的内容一起显示,或使用Web对话框显示共享屏幕。即
if (FacebookDialog.canPresentShareDialog(getApplicationContext(),
FacebookDialog.ShareDialogFeature.SHARE_DIALOG))
{
// Publish the post using the Share Dialog
FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
.setLink("https://developers.facebook.com/android")
.build();
uiHelper.trackPendingDialogCall(shareDialog.present());
}
else
{
// Fallback. For example, publish the post using the Feed Dialog
}
这是其他选项的例子
private void publishFeedDialog() {
Bundle params = new Bundle();
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
params.putString("link", "https://developers.facebook.com/android");
params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(getActivity(),
Session.getActiveSession(),
params))
.setOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(Bundle values,
FacebookException error) {
if (error == null) {
// When the story is posted, echo the success
// and the post Id.
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(getActivity(),
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(getActivity().getApplicationContext(),
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
并且不要总是依靠模拟器来检查事情。毕竟它只是一个"模拟器" 。您可以在真实设备上轻松预览应用。因此,如果事情无法在模拟器上运行,请在真实设备上进行验证。 (当然,我同意,当你没有多个设备,屏幕尺寸等时,模拟器很好。)
PS:您还需要在fb开发者网站的应用设置页面中正确设置Key Hashes。
