先看布局

DrawerLayout＋NavigationView

headerLayout+menu

---

代码

第一步:NavigationView设置监听事件 

setNavigationItemSelectedListener

第二步:DrawerLayout和toolbar整合

toolBar.inflateMenu(R.menu.toolbar_menu);

ActionBarDrawerToggledrawerToggle=newActionBarDrawerToggle(this,myDrawerlayout,toolBar,R.string.open,R.string.close);

drawerToggle.syncState();

myDrawerlayout.addDrawerListener(drawerToggle);

private voidinitDrawerLayout(){

view=myNavigationview.getHeaderView(0);

view.setOnClickListener(newView.OnClickListener(){

@Override

public voidonClick(Viewview){

Toast.makeText(MainActivity.this,"点击了header",Toast.LENGTH_SHORT).show();

}

});

myNavigationview.setNavigationItemSelectedListener(newNavigationView.OnNavigationItemSelectedListener(){

@Override

public booleanonNavigationItemSelected(@NonNullMenuItemitem){

switch(item.getItemId()){

caseR.id.menu_app_update:

Toast.makeText(MainActivity.this,"应用更新",Toast.LENGTH_SHORT).show();

break;

caseR.id.menu_message:

Toast.makeText(MainActivity.this,"消息中心",Toast.LENGTH_SHORT).show();

break;

caseR.id.menu_setting:

Toast.makeText(MainActivity.this,"设置",Toast.LENGTH_SHORT).show();

break;

}

return false;

}

});

toolBar.inflateMenu(R.menu.toolbar_menu);

ActionBarDrawerToggledrawerToggle=newActionBarDrawerToggle(this,myDrawerlayout,toolBar,R.string.open,R.string.close);

drawerToggle.syncState();

myDrawerlayout.addDrawerListener(drawerToggle);

}
