如何使用下载URI设置导航抽屉中显示的用户图像

我使用firebase存储来存储图像，我做得很好，但是我无法在导航抽屉图像查看器中显示我为用户上传的图像

Answer 1

更改此ID是不匹配的

使用此

final ImageView imageViewUser =  (ImageView)headerView.findViewById(R.id.profile_image);

而不是

final ImageView imageViewUser =  (ImageView)headerView.findViewById(R.id.txtFullName);

修改

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    View headerView = navigationView.getHeaderView(0);

    final ImageView imageViewUser =  (ImageView)headerView.findViewById(R.id.profile_image);



    StorageReference storageRef = fStorage.getReference().child("users").child(mAuth.getCurrentUser().getUid());
    storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
        @Override
        public void onSuccess(Uri uri) {

            Log.i("URI VALUE","->"+ uri)
            progressDialog.dismiss();

            Picasso.with(UserProfileActivity.this).load(uri).fit().centerCrop().into(imageViewUser);

        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
 cannot be converted to OnNavigationItemSelectedListener get this error on the line View headerView = navigationView.getHeaderView(0);
            progressDialog.dismiss();
            Toast.makeText(UserProfileActivity.this, "" + e.getMessage(), Toast.LENGTH_SHORT).show();

        }
    });

编辑新

final ImageView imageViewUser =  (ImageView)navigationView.getHeaderView(0).(R.id.profile_image);

Answer 2

尝试以下代码

  NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);


StorageReference storageRef = fStorage.getReference().child("users").child(mAuth.getCurrentUser().getUid());
storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
    @Override
    public void onSuccess(Uri uri) {
        View headerView = navigationView.getHeaderView(0);

final ImageView imageViewUser =  (ImageView)headerView.findViewById(R.id.profile_image);
        progressDialog.dismiss();

        Picasso.with(UserProfileActivity.this).load(uri).fit().centerCrop().into(imageViewUser);

    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {

        progressDialog.dismiss();
        Toast.makeText(UserProfileActivity.this, "" + e.getMessage(), Toast.LENGTH_SHORT).show();

    }
});

Answer 3

使用此方法，我将url保存到我的数据库存储

    private void changeUserPhoto() {

    StorageReference storageRef = fStorage.getReference().child("users").child(mAuth.getCurrentUser().getUid());
    storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
        @Override
        public void onSuccess(Uri uri) {

            photoURL = uri.toString();
            Picasso.with(UserProfileActivity.this).load(uri).fit().centerCrop().into(imageView);

        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {


        }
    });

}

另外，我使用url制作导航标题图像

private void changePhoto(String myUrl) {

    Picasso.with(this).load(myUrl).transform(new PhotoCircleTransform()).into(profile_image);
}
