So erhalten Sie die Schaltfläche in FrameLayout für NavigationDrawer

Question

Ich bin neu in NavigationDrawer, der folgende Code funktioniert.

Aber wie bekomme ich den Knopf in der homeLayout.axml, die wie in HomeFragment.cs nach dem untenstehenden Code angezeigt aufgeblasen wird.

ft.Add(Resource.Id.HomeFrameLayout, new HomeFragment()); 
    ft.Commit(); 

1) Ich brauche Eventhandler zu diesem BTN hinzuzufügen: btnProducts in homeLayout.axml
- wo unter Code hinzufügen
, was ich Setup-Code hinzufügen müssen die btnProducts zu erhalten und fügen Sie Ereignis für diese Taste??

SetContentView (Resource.Layout.????); 
    Btn = FindViewById<Button>(Resource.Id.BtnGM); 
    Btn.Click += Btn_Click1;

Answer 1

in Ihrem HomeFragment.cs im OnCreateView Methode fügen Sie die folgende (zwischen der Erklärung der Ansicht und der Rückkehr statment):

var btnProducts = view.FindViewById<Button>(Resource.Id.btnProducts); 
btnProducts.Click += btnProducts_Click; 

dann die Methode für Ihr Click-Ereignis hinzufügen (irgendwo in Ihrer HomeFragment Klasse):

public void btnProducts_Click(object sender, EventArgs e) 
{ 
    // Action you want to take upon button click 
}
