导航抽屉插入主事件

Question

我使用下面的抽屉布局。所以我的片段附加到工具栏下面的框架布局。当我显示片段时，我将home按钮从humburger更改为箭头：

drawerToggle.setDrawerIndicatorEnabled(b);
getSupportActionBar().setDisplayHomeAsUpEnabled(show);

问题是-当我单击箭头按钮时，活动或片段中没有onOptionsItemSelec的事件。如果我没有使用抽屉oggle.set抽屉指示器启用（b）；箭头按钮将打开抽屉菜单。如何修复这种行为？

布局

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true"
        android:orientation="vertical">

        <include
            android:id="@+id/toolbar"
            layout="@layout/tool_bar" />

        <FrameLayout
            android:id="@+id/frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

        </FrameLayout>
    </RelativeLayout>

    <LinearLayout

    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

导航抽屉设置

public void setUpNavigationDrawer(){
        int width = getResources().getDisplayMetrics().widthPixels * 3 / 4;
        DrawerLayout.LayoutParams params =
            (android.support.v4.widget.DrawerLayout.LayoutParams) navigationHolder.getLayoutParams();
        params.width = width;
        navigationHolder.setLayoutParams(params);
        mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
        drawerToggle = new ActionBarDrawerToggle(
            this, mDrawerLayout, mToolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close
        ){

            @Override
            public void onDrawerOpened(View drawerView){
                super.onDrawerOpened(drawerView);

                if(!mUserLearnedDrawer){
                    mUserLearnedDrawer = true;
                    SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(
                        mContext
                    );
                    sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).apply();
                }
                invalidateOptionsMenu();

            }


            @Override
            public void onDrawerSlide(View drawerView, float slideOffset){
                super.onDrawerSlide(drawerView, slideOffset);
            }


            @Override
            public void onDrawerClosed(View drawerView){
                super.onDrawerClosed(drawerView);
                if(needToChangePage){
                    onNavigationDrawerItemSelected(
                        (int) drawerView.getTag()
                    );
                }
                needToChangePage = false;

            }
        };

        if(!mUserLearnedDrawer){
            mDrawerLayout.openDrawer(navigationHolder);
        }
        mDrawerLayout.post(
            new Runnable(){

                @Override
                public void run(){
                    drawerToggle.syncState();
                }
            }
        );
        mDrawerLayout.setDrawerListener(drawerToggle);
    }

使用碎片时，在Android导航抽屉图像和插入符号之间切换尝试了从这里开始的方法，但结果相同

要收听点击android. R.id.home当抽屉菜单设置它的必要添加工具栏侦听器

drawerToggle.setToolbarNavigationClickListener(
            new View.OnClickListener(){

                @Override
                public void onClick(View v){
                    getSupportFragmentManager().popBackStackImmediate();
                }
            }
        );

此侦听器将只发，如果抽屉oggle.setDrawerIndicator启用（false）；
