Question

我的应用程序中有三个按钮。一种用于相机，第二种用于画廊，第三种用于上传。我将上传方法从网络服务器更改为Google Firebase。目前，我只能通过相机按钮上传。如果我尝试从图库按钮上载，它将开始在一个临时文件夹中搜索图像，该临时文件夹将在相机拍摄图像时将其保存。

从图库中获取图片：

    private void ImageSelection()
{
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(intent, IMAGE_REQUEST);

}

关于活动方法：

        else if (requestCode == IMAGE_REQUEST && resultCode == RESULT_OK && data != null)
    {

        Uri FilePath = data.getData();
        try {

            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), FilePath);
            mImageView.setImageBitmap(bitmap);
            mImageView.setVisibility(View.VISIBLE);
            mEditText.setVisibility(View.VISIBLE);
            staticSpinner.setVisibility(View.VISIBLE);

            if (TextUtils.isEmpty(mEditText.getText())){
                mEditText.setError("Privalomas laukas");
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

上传方法：

private void UploadImage() {

    if(photoFile != null)
    {
        final ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("Uploading...");
        progressDialog.show();

        StorageReference ref = storageReference.child("images/"+ staticSpinner.getSelectedItem().toString().trim()+"_"+ mEditText.getText().toString());
        ref.putFile(Uri.fromFile(photoFile))
                .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        progressDialog.dismiss();
                        Toast.makeText(MainActivity.this, "Uploaded", Toast.LENGTH_SHORT).show();
                        mImageView.setImageResource(0);
                        mImageView.setVisibility(View.GONE);
                        mEditText.setText("");
                        mEditText.setVisibility(View.GONE);
                        staticSpinner.setVisibility(View.GONE);
                        mCapture.setVisibility(View.VISIBLE);
                        mChoose.setVisibility(View.VISIBLE);
                        //mUpload.setVisibility(View.GONE);
                        photoFile = new File(String.valueOf(photoFile));
                        photoFile.delete();
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        progressDialog.dismiss();
                        Toast.makeText(MainActivity.this, "Failed "+e.getMessage(), Toast.LENGTH_SHORT).show();
                        mImageView.setImageResource(0);
                        mImageView.setVisibility(View.GONE);
                        mEditText.setText("");
                        mEditText.setVisibility(View.GONE);
                        staticSpinner.setVisibility(View.GONE);
                        mCapture.setVisibility(View.VISIBLE);
                        mChoose.setVisibility(View.VISIBLE);
                        //mUpload.setVisibility(View.GONE);
                        photoFile = new File(String.valueOf(photoFile));
                        photoFile.delete();
                    }
                })
                .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                        double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot
                                .getTotalByteCount());
                        progressDialog.setMessage("Uploaded "+(int)progress+"%");
                    }
                });
    }
}

添加了一个else if语句。愚蠢的我

如何不仅从相机上传图像？
