Change layout programmatically

yudi — Tue, 30 Sep 2014 10:15:48 GMT

I managed to add TextView into LinearLayout by overriding OnCreate method. The snippet code below shows how.

public class SimpleActivity : Activity<SimpleViewModel>
{
    #region Constructors

    public SimpleActivity()
        : base(Resource.Layout.MainLayout)
    {
    }

    protected override void OnCreate(global::Android.OS.Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
                                                                   
        LinearLayout mainView = this.FindViewById<LinearLayout>(Resource.Id.Container);

        TextView txtView = new TextView(this);
        txtView.SetTextColor(global::Android.Graphics.Color.ParseColor("#FFFFFF"));
        txtView.SetTextAppearance(this, global::Android.Resource.Style.TextAppearanceMedium);
        txtView.Text = "test";

        mainView.AddView(txtView);
    }

    #endregion
}

Hope this helps.

Change layout programmatically

Hello Crosslight Support,

what is the best/recommended way to change layouts programmatically (e.g. adding buttons or textviews)?

I tried this on Android, but I got stuck.

I wasn't able to get the main view of the current activity to add additional "sub"views.

I have the following code as constructor of my activity:

public SimpleActivity(): base(Resource.Layout.MainLayout){}

To get a reference to the main view (MainLayout) of the "SimpleActivity" I tried:

LinearLayout mainView = (LinearLayout)this.FindViewById(this.ContentLayoutId);

within OnViewCreated, OnViewInitialized, InitializeView but the mainView variable is always "null".

Thanks for your support.

Thomas
