Question

我是Android的新用户，我在从FirebaseStorage显示图片时遇到问题。

这是MainActivity.java中的代码：

ImageView image = (ImageView) findViewById(R.id.profilePic_image_view);

mStorage = FirebaseStorage.getInstance().getReference();
Uri downloadURI = mStorage.child("circleako.png").getDownloadUrl().getResult();

Picasso.with(MainActivity.this).load(downloadURI).fit().centerCrop().into(image);

在我的gradle里面是这些：

compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.firebase:firebase-storage:9.6.1'
compile 'com.google.android.gms:play-services-base:10.0.1'
compile 'com.google.android.gms:play-services-maps:10.0.1'
compile 'com.google.android.gms:play-services-location:10.0.1'
compile 'com.google.android.gms:play-services-analytics:10.0.1'
compile 'com.squareup.picasso:picasso:2.5.2'
testCompile 'junit:junit:4.12'

这是错误：

Answer 1

你可以使用Glide。使用Glide，您也可以显示GIF动画。

String urlImage = "You URL Image";

Glide.with(yourActivity.this)
        .load(urlImage)
        .into(yourImageView);

在gradle-app中：

compile 'com.github.bumptech.glide:glide:3.7.0'

Answer 2

清理项目并在设备上完全重新安装应用程序，这似乎是即时运行的问题。

另外，我建议使用Glide而不是Picasso和Firebase存储（或者从URL加载图像的情况）。毕加索没有很好地处理EXIF，因此在某些情况下它可能会导致图像方向问题等问题。

编辑：

mStorage.child("circleako.png").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
    @Override
    public void onSuccess(Uri uri) {
        Picasso.with(MainActivity.this).load(uri).fit().centerCrop().into(image);
    }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception exception) {
            // Handle any errors
        }
});
