从android手机摄像头拍摄照片并将其上传到facebook群组
问题描述:
我使用hackbook中的代码进行android教程,并且我已经能够将照片上传到我的墙上。我现在想要的是上传从我的相机拍摄的照片,并将其上传到某个组的相册中。从android手机摄像头拍摄照片并将其上传到facebook群组
我认为需要修改的那部分代码是这样的:
/*
* Source Tag: upload_photo You can upload a photo from the media
* gallery or from a remote server How to upload photo:
* https://developers.facebook.com/blog/post/498/
*/
case 3: {
if (!Utility.mFacebook.isSessionValid()) {
Util.showAlert(this, "Warning", "You must first log in.");
} else {
dialog = ProgressDialog.show(Hackbook.this, "",
getString(R.string.please_wait), true, true);
new AlertDialog.Builder(this)
.setTitle(R.string.gallery_remote_title)
.setMessage(R.string.gallery_remote_msg)
.setPositiveButton(R.string.gallery_button,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Intent.ACTION_PICK,
(MediaStore.Images.Media.EXTERNAL_CONTENT_URI));
startActivityForResult(intent,
PICK_EXISTING_PHOTO_RESULT_CODE);
}
})
.setNegativeButton(R.string.remote_button,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
/*
* Source tag: upload_photo_tag
*/
Bundle params = new Bundle();
params.putString("url",
"http://www.facebook.com/images/devsite/iphone_connect_btn.jpg");
params.putString("caption",
"FbAPIs Sample App photo upload");
Utility.mAsyncRunner.request("me/photos", params,
"POST", new PhotoUploadListener(), null);
}
}).setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface d) {
dialog.dismiss();
}
}).show();
}
break;
}
所以,你能帮帮我这句话: 1)这可能吗?或者我必须先拍照,存放在某个地方然后找到它。我想避免这种情况(我的意思是用户 - 如果它可以通过编程的方式完成,那么就没有问题)。 2)我需要更改哪些参数?

尝试 -
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
photoButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap bmp = intent.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray(); // convert camera photo to byte array
}
}
你的Facebook类 -
public void onClick(DialogInterface dialog, int which) {
Bundle params = new Bundle();
params.putByteArray("picture", <image in bytes>);
params.putString("message", "Have fun");
mAsyncRunner.request("me/photos", bundle, "POST", new SampleUploadListener());
}

这是可能的。 在摄像头方面,你应该参考Android developer site并从他们提供的,你可以弄清楚如何临时存储数据,并上传PIC给Facebook我用下面的代码
private void upload_FB(Bitmap photo2) {
// TODO Auto-generated method stub
Calendar c = Calendar.getInstance();
String name = c.getTime().toString()+" Vai vajadzētu iegādāties?";
AsyncFacebookRunner fruner = new AsyncFacebookRunner(facebook);
Log.d("adr", mCurrentPhotoPath);
if(photo2!=null && mCurrentPhotoPath!=null){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
photo2.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] bMapArray = baos.toByteArray();
Bundle params = new Bundle();
params.putByteArray("photo",bMapArray);
params.putString("caption", name);
params.putString("comments", ed1.getText().toString());
fruner.request("me/photos",params,"POST",new PhotoUploadListener(),null);
}
}
祝你好运:)
