我知道现在我们不能使用getDownloadUrl在firebase-firestore上更新图像，但是我找不到找到它的一种方法。
您在其中的图片onClickListenner：
imagem.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
if(ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED){
Toast.makeText(getActivity(),"Permission Denied", Toast.LENGTH_LONG).show();
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},1);
}else {
CropImage.activity().setGuidelines(CropImageView.Guidelines.ON).setAspectRatio(1,1).start(getActivity());
}
}
}
});
我正在像这样使用CropImage：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
mainImage = result.getUri();
imagem.setImageURI(mainImage);
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
Toast.makeText(getActivity(),"Erro "+ error, Toast.LENGTH_LONG).show();
}
}
}
您可以在其中将按钮保存在Firestore-firebase上的图像：
bGuardar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mainImage != null){
StorageReference image_path = storageReference.child("profile_images").child(user_id + ".jpg");
image_path.putFile(mainImage).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()){
//AQUI
Uri download_uri = task.getResult().getDownloadUrl();
Log.d("Erro", "errrrooooo: " + download_uri);
}else{
String erro = task.getException().getMessage();
Toast.makeText(getActivity(),"Erro: "+erro, Toast.LENGTH_LONG).show();
}
}
});
}
}
});
我正在使用片段，这就是为什么我使用“ getActivity”而不是“ this”的原因
