android - 如何显示或从 Firebase 存储中获取图像

Question

我是 Android 新手，在显示来自 FirebaseStorage 的图像时遇到问题。

这是我在 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 中有这些:

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

您可以使用 Glide。使用 Glide，您也可以显示动画 gif。

String urlImage = "You URL Image";

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

在 gradle-app 中放置:

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