从本地存储将文件上传到Firebase

Question

我正在制作一个聊天应用程序，在这里我们可以将文件上传到firebase，就像选择图片选择器一样，如果我们选择图片，然后单击它，然后选择并发送并聊天聊天图片，例如whatsapp。 照片选择器的意图工作正常，但是当我选择图像时，它无法发送图像，因此无法上传

触发光电选择器的代码意图：

       mPhotoPickerButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    // TODO: Fire an intent to show an image picker
                    Log.d(TAG, "onClick: is it working?");
                    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
                    intent.setType("image/*");
                    intent.putExtra(Intent.EXTRA_LOCAL_ONLY,true);
                    startActivityForResult(Intent.createChooser(intent,"Complete action using"),RC_PHOTO_PICKER);
                }
            });

拾取要上传的照片的代码是：

else if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK){
                   Uri selectedImageUri = data.getData();
                   StorageReference photoRef = mStorageReference.child(selectedImageUri.getLastPathSegment());

                   //upload file to firebase storage
                   photoRef.putFile(selectedImageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                       @Override
                       public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                           Uri downloadUrl =   taskSnapshot.getDownloadUrl();
                           FriendlyMessage friendlyMessage = new FriendlyMessage(null,mUsername,downloadUrl.toString());
                           mMessageDatabaseReference.push().setValue(friendlyMessage);
                       }
                   });

FriendlyMessage.java

包com.google.firebase.udacity.friendlychat;

public class FriendlyMessage {

    private String text;
    private String name;
    private String photoUrl;

    public FriendlyMessage() {
    }

    public FriendlyMessage(String text, String name, String photoUrl) {
        this.text = text;
        this.name = name;
        this.photoUrl = photoUrl;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhotoUrl() {
        return photoUrl;
    }

    public void setPhotoUrl(String photoUrl) {
        this.photoUrl = photoUrl;
    }
}

是的，我发现了问题

将FriendlyMessageModel类的所有成员公开！

public class FriendlyMessage {

    public String text;
    public String name;
    public String photoUrl;

    public FriendlyMessage() {
    }

    public FriendlyMessage(String text, String name, String photoUrl) {
        this.text = text;
        this.name = name;
        this.photoUrl = photoUrl;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhotoUrl() {
        return photoUrl;
    }

    public void setPhotoUrl(String photoUrl) {
        this.photoUrl = photoUrl;
    }
}
