Question

嗨我下载存储它的图像并试图分享它但我的应用程序刷新我转发预先准备，如果有人能找到错误并解释为什么会发生这种情况

   \b[\d]+[.,][\d]+\b

firebase stuf @覆盖 protected void onStart（）{ super.onStart（）;

public class NoticiasActivity extends AppCompatActivity {

    private RecyclerView mBlogList;
    FirebaseDatabase database;
    DatabaseReference myRef;
    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_noticias);

    //Recycler View
    mBlogList = (RecyclerView)findViewById(R.id.blog_list);
    mBlogList.setHasFixedSize(true);
    mBlogList.setLayoutManager(new LinearLayoutManager(this));

    // Send a Query to the database
    database = FirebaseDatabase.getInstance();
    myRef = database.getReference("Data");
}

在这里我实现所有它似乎有问题找到文件

    FirebaseRecyclerAdapter<ModelClass, BlogViewHolder> firebaseRecyclerAdapter =
            new FirebaseRecyclerAdapter<ModelClass, BlogViewHolder>(
                    ModelClass.class,
                    R.layout.design_row,
                    BlogViewHolder.class,
                    myRef)  {



                @Override
                protected void populateViewHolder(BlogViewHolder viewHolder, ModelClass model, final int position) {
                    viewHolder.setTitle(model.getTitle());
                    viewHolder.setImage(getApplicationContext(), model.getImage());

这是我的日志
