java - FirebaseStorage.getReferenceFromUrl(来源未知)

Question

过去两天我收到此错误，我不知道如何解决它，我需要在我使用 RecycleView 的 Android 应用程序中获取存储在 Firebase 中的数据(图像)作为 ListView ；

这是主类:

public class MainActivityPersistent extends AppCompatActivity {

    private static final String G_DB_URL = "https://fir-test-ca03d.firebaseio.com/tutorial/list";
    //where the data stored in the firebase
    private boolean isEnabled;

    @Override protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if(!isEnabled) {
            try {
                FirebaseDatabase.getInstance().setPersistenceEnabled(true);
                isEnabled = true;
            } catch (RuntimeException e) { }
        }

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        RecyclerView mRecyclerView = (RecyclerView) findViewById(R.id.list);
        final ProgressBar mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
        mProgressBar.setVisibility(View.VISIBLE);
        LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager( this );

        mRecyclerView.setLayoutManager(mLinearLayoutManager);
        DatabaseReference ref = FirebaseDatabase.getInstance().getReferenceFromUrl(G_DB_URL);

        FirebaseRecyclerAdapter<DataModel, ListRowHolder> mAdapter = new FirebaseRecyclerAdapter<DataModel, ListRowHolder>(
            DataModel.class,
            R.layout.list_row_item, ListRowHolder.class, ref
        ) {
            @Override protected void populateViewHolder(final ListRowHolder viewHolder,
            DataModel model, int position) {
                mProgressBar.setVisibility(View.GONE);

                final StorageReference ref = FirebaseStorage.getInstance().getReferenceFromUrl(model.image);

                viewHolder.description.setText(model.description);
                Glide.with(MainActivityPersistent.this)
                    .using(new FirebaseImageLoader())
                    .load(ref)
                    .into(viewHolder.image);
            }
        };
    }
}

这是我运行应用程序时遇到的错误:

E/AndroidRuntime: FATAL EXCEPTION: main
                  Process: com.myapplication, PID: 21238
                  java.lang.IllegalArgumentException: The storage Uri could not be parsed.

Answer 1

FirebaseDatabase.getInstance().getReference(G_DB_URL);

从您的 Firebase 引用中更改此设置
