[英]Share image in Facebook programmatically from Android app via Intent
[英]facebook share image is not showing on facebook via android app
我是 facebook 集成的新手,我已经为此工作了几天,我相信我能够解决这个问题。 我的问题是,我为共享对话框附加的图像未显示在 facebook 上。
这是我的代码:
public class ViewPagerAdapter extends PagerAdapter {
Context context;
String[] rank;
String[] country;
String[] population;
int[] bookCover;
LayoutInflater inflater;
@Override public Object instantiateItem(ViewGroup container, final int position) {
final PdfHandler pdf = new PdfHandler(context);
final int pdfPos = position;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.viewpager_item, container, false);
ImageView imgflag = (ImageView) itemView.findViewById(R.id.flag);
// Capture position and set to the ImageView
//imgflag.setScaleType(ScaleType.FIT_XY);
imgflag.setImageResource(bookCover[position]);
// Add viewpager_item.xml to ViefeewPager
((ViewPager) container).addView(itemView);
imgflag.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
int data = bookCover[position];
shareImage(data);
}
});
return itemView;
}
public void shareImage(int data) {
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.putInt("picture", data );
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(context,
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(context,
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(context,
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(context,
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(context,
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
使用饲料对话框或饲料图形API你不能传递的图像数据picture
。 所以你应该提供一个 url 而不是数据。
只是一个技巧 - 您可以首先使用/photos
上传图片,您可以在其中使用图像数据,然后您可以将此图像网址用于提要。
跳它有帮助。 祝你好运!
