ScrollView重叠ActionBar，防止选择按钮

Question

当我更改活动中片段的布局时，操作栏中的菜单选项似乎停止工作。按钮（搜索图标和导航拖动器图标）无响应。

这是具有工作菜单选项的片段的布局文件： activity_login.xml（正常工作）

while((blarp = getchar()) != EOF)
while((blarp = getchar()) != EOF && blarp != '\n')

这是似乎打破按钮的布局文件： activity_login.xml（非工作）

我似乎无法锻炼为什么更改布局会打破ActionBar菜单选项，任何帮助都会受到赞赏。

修改 将public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener, LoginFragment.OnLoginCallback { MenuItem register; MenuItem login; MenuItem logout; MenuItem completeListing; MenuItem expiredListing; MenuItem activeListing; NavigationView navigationView; UserCredentialHandler userStatus; protected static final String KEY_USER_STATUS = "USER_STATUS"; protected static final String USER_PREFS = "userNamePrefs"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); userStatus = new UserCredentialHandler(); final HomeFragment homeFragment = new HomeFragment(); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle( this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); drawer.setDrawerListener(toggle); toggle.syncState(); FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent i = new Intent(getApplicationContext(), CreateListingActivity.class); startActivity(i); } }); navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); getMenuItems(navigationView); if(userStatus.checkIfUserIsLoggedIn(getApplicationContext())){ userStatus.setNavHeaderOnLogin(getApplicationContext(), navigationView); updateNavDrawer("login", register, login, logout, expiredListing, completeListing, activeListing); } else { userStatus.setNavHeaderOnLogout(navigationView); updateNavDrawer("logout", register, login, logout, expiredListing, completeListing, activeListing); } FragmentManager fragmentManager = getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); fragmentTransaction.replace(R.id.main_container,homeFragment); fragmentTransaction.commit(); } @Override public void onLoginSuccess() { HomeFragment homeFragment = new HomeFragment(); userStatus.setNavHeaderOnLogin(getApplicationContext(), navigationView); updateNavDrawer("login",register,login,logout, expiredListing, completeListing, activeListing); register.setVisible(false); login.setVisible(false); logout.setVisible(true); FragmentManager fragmentManager = getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); fragmentTransaction.replace(R.id.main_container,homeFragment); fragmentTransaction.commit(); } @Override public void onBackPressed() { DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); if (drawer.isDrawerOpen(GravityCompat.START)) { drawer.closeDrawer(GravityCompat.START); } else { getSupportFragmentManager().popBackStack(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main_activity_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } else if (id == R.id.search_mag_icon){ SearchFragment searchFragment = new SearchFragment(); getSupportFragmentManager() .beginTransaction() .replace(R.id.main_container, searchFragment) .addToBackStack(null) .commit(); } return super.onOptionsItemSelected(item); } @SuppressWarnings("StatementWithEmptyBody") @Override public boolean onNavigationItemSelected(MenuItem item) { // Handle navigation view item clicks here. int id = item.getItemId(); if (id == R.id.nav_register) { final RegisterFragment registerFragment = new RegisterFragment(); getSupportFragmentManager() .beginTransaction() .replace(R.id.main_container, registerFragment) .addToBackStack(null) .commit(); } else if (id == R.id.nav_login) { final LoginFragment loginFragment = new LoginFragment(); getSupportFragmentManager() .beginTransaction() .replace(R.id.main_container, loginFragment) .addToBackStack(null) .commit(); } else if(id == R.id.nav_logout) { userStatus.logoutUser(getApplicationContext()); userStatus.setNavHeaderOnLogout(navigationView); updateNavDrawer("logout",register,login,logout, expiredListing, completeListing, activeListing); } else if (id == R.id.nav_my_listings) { // navigate to my listings } else if (id == R.id.nav_how) { // navigate to how it works page } else if (id == R.id.nav_help) { // navigate to help page } else if (id == R.id.nav_contact_us) { // navigate to contact page, } DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); drawer.closeDrawer(GravityCompat.START); return true; } private void updateNavDrawer(String action, MenuItem register, MenuItem login, MenuItem logout, MenuItem expiredListing, MenuItem completeListing, MenuItem activeListing){ if(action=="login"){ register.setVisible(false); login.setVisible(false); logout.setVisible(true); completeListing.setVisible(true); activeListing.setVisible(true); expiredListing.setVisible(true); } else { register.setVisible(true); login.setVisible(true); logout.setVisible(false); completeListing.setVisible(false); activeListing.setVisible(false); expiredListing.setVisible(false); } } private void getMenuItems(NavigationView nv){ register = nv.getMenu().getItem(0); login = nv.getMenu().getItem(1); logout = nv.getMenu().getItem(2); activeListing = nv.getMenu().getItem(3); completeListing = nv.getMenu().getItem(4); expiredListing = nv.getMenu().getItem(5); } } 元素更改为<ScrollView>似乎可以解决它，但我需要一个ScrollView。 ScrollView似乎与ActionBar重叠并位于顶部。

尝试将ScrollView上的android：layout_height设置为“match_parent”而不是“wrap_content”
