工具栏和导航视图的问题

我有一个活动，里面有工具栏和navigationView。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.start_page_activity);
    getFragment(new MainFragment());
    mToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(mToolbar);
    mNavigationView = (NavigationView) findViewById(R.id.main_drawer);
    mNavigationView.setNavigationItemSelectedListener(this);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_widget);
    drawerToggle
            = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_open, R.string.drawer_close);
    mDrawerLayout.setDrawerListener(drawerToggle);
}
    @Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    Log.i("StartPageActivity", "onPostCreate");
    drawerToggle.syncState();
}

首次启动活动时称为Main Fragment。 当我在NavigationView中选择项目时打开新的片段。 当出现第二个片段时，我在里面使用

ActionBar a = ((AppCompatActivity) getActivity()).getSupportActionBar();
    a.setDisplayHomeAsUpEnabled(true);

出现向上箭头，但是当我点击此向上箭头打开NavigationVIEW !!! inOptionsItemSelected里面的片段我有

case android.R.id.home:{
            Log.i("One", "Dude");
          }

该程序不符合此代码。它没有达到它。我认为onCreate（活动）里面的问题。也许它在ActionBarDrawerToggle，NavigationView和Toolbar之间发生冲突。

添加第二个片段

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.reminder_list_fragment, container, false);
    getActivity().setTitle("Fragment1");
    mRecyclerView = (RecyclerView)v. findViewById(R.id.my_recycler_view);
    //{RecyclerAdapter}
    ActionBar a = ((AppCompatActivity) getActivity()).getSupportActionBar();
    a.setDisplayHomeAsUpEnabled(true);
    a.setHomeButtonEnabled(true);
    return v;
}
@Override
public void onResume() {
    super.onResume();
    mRecyclerView.getAdapter().notifyDataSetChanged();
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    menu.clear();
    inflater.inflate(R.menu.reminder_toolbar, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    Log.d("Testing", "ID == " + id);
    switch (id) {
        case R.id.add_information : {
            Forget f = new Forget();
            ForgetLab.get(getActivity()).addForget(f);
            FragmentManager fm = getFragmentManager();
            Fragment mFragment = fm.findFragmentById(R.id.fragment_container);
            Bundle bundle = new Bundle();
            bundle.putSerializable(ReminderFragment.EXTRA_FORGET_ID, f.getId());
            if (mFragment != null) {
                mFragment = new ReminderPagerFragment();
                mFragment.setArguments(bundle);
                fm.beginTransaction().addToBackStack(null)
                        .replace(R.id.fragment_container, mFragment)
                        .commit();
            }
            return true;
        }
        case android.R.id.home:{
            Log.i("One", "Dude");
          }
    }
    return super.onOptionsItemSelected(item);
}

您应该在setHasOptionsMenu(true)

内调用onCreate(Bundle savedInstanceState)和 @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(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 == android.R.id.home) { getActivity().onBackPressed(); } return super.onOptionsItemSelected(item); } I hope this works....

使用此完整示例。

 public abstract class BaseActivity extends AppCompatActivity{
    protected Toolbar toolbar;
    protected User mMe;
    protected DrawerLayout mDrawerLayout;
    protected ActionBarDrawerToggle drawerToggle;

    @Override
    public void setContentView(int layoutResID) {
        super.setContentView(layoutResID);
        mMe = SessionUtils.getUser();
        if (mMe == null) {
            return;
        }
        initToolbar();
        initInstances();

    }

    private void initToolbar() {
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
    }

    private void initInstances() {
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
        if (mDrawerLayout != null) {
            final NavigationView navigationView = (NavigationView) findViewById(R.id.navigation);
            ImageView profileImage = (ImageView) navigationView.findViewById(R.id.profileImage);
            profileImage.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ActivityUtils.launchProfileActivity(BaseActivity.this, SessionUtils.getUser());
                }
            });
            TextView name = (TextView) navigationView.findViewById(R.id.name);
            final String fullName = StringUtils.getFullName(mMe.firstName, mMe.lastName);
            name.setText(fullName);
            GlideUtils.load(profileImage, mMe.getImage(), GlideUtils.getCircularFallbackDrawable(this, fullName), new CircleTransformGlide(this));

            navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

                }
            });

您的主要活动必须扩展BaseActivity 

public class MainActivity extends BaseActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (!LoginManager.isFirstFlowFinished(this)) {
        LoginManager.launchCurrentFragment(this);
        finish();
        return;
    }
    Intent intent = getIntent();
    handleIntent(intent);
    setContentView(R.layout.activity_main_new);
    LogUtils.LOGD(">>Intent", "onCreate");
}

@Override
public void onResume() {
    super.onResume();
    LocationTracker.promptIfNeededForEnableLocation(this);
    CommonUtils.checkIfPlayServicesNeedToUpdate(this);
    AppEventsLogger.activateApp(this);
}

@Override
protected void onPause() {
    super.onPause();
    AppEventsLogger.deactivateApp(this);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_search, menu);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_search_icon:
            ActivityUtils.launchSearchActivity(this);
            break;
    }
    return true;
}

@Override
public void onBackPressed() {
    super.onBackPressed();
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    LogUtils.LOGD(">>Intent", "on handle Intent");
    handleIntent(intent);
}

}

这是activity_main_new.xml
