Question

首次启动应用程序时，登录后图片开始闪烁。重新启动后，此问题已解决。是MainActivity.java还是AndroidManifest.xml中的错误？

Android Studio出现错误。始终仅显示一个ViewPointer 0。

感谢您的帮助！

这是我的MainActivity.java

public class MainActivity extends AppCompatActivity {
    private Fragment selectedfragment = null;
    private FirebaseUser firebaseUser;
    private DatabaseReference reference;

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

        firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
        reference = FirebaseDatabase.getInstance().getReference("Users").child(firebaseUser.getUid());

        BottomNavigationView bottom_navigation = findViewById(R.id.bottom_navigation);
        bottom_navigation.setOnNavigationItemSelectedListener(navigationItemSelectedListener);

        bottom_navigation.getMenu().findItem(R.id.home).setChecked(true);

        Bundle intent = getIntent().getExtras();
        if (intent != null) {
            String publisher = intent.getString("publisherid");

            SharedPreferences.Editor editor = getSharedPreferences("PREFS", MODE_PRIVATE).edit();
            editor.putString("profileid", publisher);
            editor.apply();

            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new ProfileFragment()).commit();
        } else {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new HomeFragment()).commit();
        }

        ImageButton ClickImageButton = findViewById(R.id.btnLaunchCamera);
        ImageButton ClickImageButton2 = findViewById(R.id.imageButton2);

        ClickImageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(MainActivity.this, PostActivity.class));
            }
        });

        ClickImageButton2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(MainActivity.this, OptionsActivity.class));
            }
        });

        SearchView searchView = (SearchView) findViewById(R.id.searchView_home);

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });
    }

    private final BottomNavigationView.OnNavigationItemSelectedListener navigationItemSelectedListener =
            new BottomNavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(@NonNull MenuItem item) {

                    switch (item.getItemId()) {
                        case R.id.chat_notification:
                            selectedfragment = new ChatNotificationFragment();
                            break;
                        case R.id.home:
                            selectedfragment = new HomeFragment();
                            break;
                        case R.id.profile:
                            SharedPreferences.Editor editor = getSharedPreferences("PREFS", MODE_PRIVATE).edit();
                            editor.putString("profileid", Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getUid());
                            editor.apply();
                            selectedfragment = new ProfileFragment();
                            break;
                    }
                    if (selectedfragment != null) {
                        getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, selectedfragment).commit();
                    }
                    return true;
                }
            };

    private void status(String status){
        reference = FirebaseDatabase.getInstance().getReference("Users").child(firebaseUser.getUid());

        HashMap<String, Object> hashMap = new HashMap<>();
        hashMap.put("status", status);

        reference.updateChildren(hashMap);
    }

    @Override
    protected void onResume() {
        super.onResume();
        status("online");
    }

    @Override
    protected void onPause() {
        super.onPause();
        status("offline");
    }
}

还有LoginActivity.class

public class LoginActivity extends AppCompatActivity {

    private EditText email;
    private EditText password;
    private FirebaseAuth auth;

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

        email = findViewById(R.id.email);
        password = findViewById(R.id.password);
        Button login = findViewById(R.id.login);
        TextView txt_signup = findViewById(R.id.txt_signup);
        auth = FirebaseAuth.getInstance();

        txt_signup.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(LoginActivity.this, RegisterActivity.class));
            }
        });

        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final ProgressDialog pd = new ProgressDialog(LoginActivity.this);
                pd.setMessage("Please wait...");
                pd.show();

                String str_email = email.getText().toString();
                String str_password = password.getText().toString();

                if (TextUtils.isEmpty(str_email) || TextUtils.isEmpty(str_password)){
                    Toast.makeText(LoginActivity.this, "All fields are required!", Toast.LENGTH_SHORT).show();
                } else {

                    auth.signInWithEmailAndPassword(str_email, str_password)
                            .addOnCompleteListener(LoginActivity.this, new OnCompleteListener<AuthResult>() {
                                @Override
                                public void onComplete(@NonNull Task<AuthResult> task) {
                                    if (task.isSuccessful()) {

                                        DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("Users")
                                                .child(Objects.requireNonNull(auth.getCurrentUser()).getUid());

                                        reference.addValueEventListener(new ValueEventListener() {
                                            @Override
                                            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                                                pd.dismiss();
                                                Intent intent = new Intent(LoginActivity.this, MainActivity.class);
                                                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                                                startActivity(intent);
                                                finish();
                                            }

                                            @Override
                                            public void onCancelled(@NonNull DatabaseError databaseError) {
                                                pd.dismiss();
                                            }
                                        });
                                    } else {
                                        pd.dismiss();
                                        Toast.makeText(LoginActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show();
                                    }
                                }
                            });
                }
            }
        });
    }
}

这是我发现很重要的日志。

Answer 1

我完全确定您遇到的问题。但是，我可以指出一些在您更改代码以解决问题时考虑到的有用信息。

首先，让我们考虑以下消息。

未使用平台默认值指定网络安全配置

您需要按照guideline here进行设置，以设置网络配置。

跳过88帧！该应用程序可能对其进行了过多的工作主线程

正如您已经提到的那样，您的应用程序在其主线程中做了太多工作。因此，您需要检查是否有可能在后台任务中移动任何内容，以便主线程仅执行填充初始视图所需的操作。

在课程中找不到视图的设置器/字段 com.bbinkconnect.bbinktattoo.model.Story

请检查此类，并写二传手的观点，并将二传手公开。

登录后，我认为您正在加载HomeFragment，这在主线程中工作量很大。如果它正在从网络从主线程加载图像，请考虑使用Glide。

希望对您有所帮助！

当应用程序首次启动时，图片开始闪烁。重新启动后，此问题已解决。为什么？
