C# 使布局不可见

我有线性布局

我希望它在文本添加到文本字段之前不可见

代码

private void显示（）{
LinearLayout display2=FindViewById（Resource.Id.LinearLayout2）；
//LinearLayout display=findviewbyd（Resource.Id.linearLayout13）；
TextView productname=FindViewById（Resource.Id.PostTitle）；
TextView price=findviewbyd（Resource.Id.price）；
TextView-weight=findviewbyd（Resource.Id.weight）；
productname.Text=Intent.GetStringExtra（“标题”）；
price.Text=Intent.GetStringExtra（“价格”）；
weight.Text=Intent.GetStringExtra（“重量”）；
display2.Visibility=ViewStates.Visible；
productname.Visibility=ViewState.Visible；
price.Visibility=ViewStates.Visible；
weight.Visibility=ViewStates.Visible；
}

我的axml

将使您的线性布局不可见

    display2.setVisibility(View.VISIBLE);

将使它出现。

这就是答案

    private void Display (){
        LinearLayout display2 = FindViewById<LinearLayout> (Resource.Id.linearLayout12);        
        //LinearLayout display = FindViewById<LinearLayout> (Resource.Id.linearLayout13);           
        TextView productname = FindViewById<TextView> (Resource.Id.posttittle);
        TextView price = FindViewById<TextView> (Resource.Id.price);
        TextView weight = FindViewById<TextView> (Resource.Id.weight);


        productname.Text = Intent.GetStringExtra ("title");

        if (productname.Text == Intent.GetStringExtra ("title")) {
            display2.Visibility = ViewStates.Visible;
        } 
        else {
            display2.Visibility = ViewStates.Gone;
        }


        price.Text = Intent.GetStringExtra("price");
        weight.Text = Intent.GetStringExtra("weight");
        //display2.Visibility = ViewStates.Visible;
        productname.Visibility = ViewStates.Visible;
        price.Visibility = ViewStates.Visible;
        weight.Visibility = ViewStates.Visible;
    }

private void显示（）{
LinearLayout display2=FindViewById（Resource.Id.LinearLayout2）；
//LinearLayout display=findviewbyd（Resource.Id.linearLayout13）；
TextView productname=FindViewById（Resource.Id.PostTitle）；
TextView price=findviewbyd（Resource.Id.price）；
TextView-weight=findviewbyd（Resource.Id.weight）；
productname.Text=Intent.GetStringExtra（“标题”）；
如果（productname.Text==Intent.GetStringExtra（“标题”））{
display2.Visibility=ViewStates.Visible；
} 
否则{
display2.Visibility=ViewStates.Gone；
}
price.Text=Intent.GetStringExtra（“价格”）；
weight.Text=Intent.GetStringExtra（“重量”）；
//display2.Visibility=ViewStates.Visible；
productname.Visibility=ViewState.Visible；
price.Visibility=ViewStates.Visible；
weight.Visibility=ViewStates.Visible；
}

yourView.setVisibility（View.INVISIBLE）；这是java代码。我用c#。我在axml中将其设置为不可见。当Display（）运行@SarthakMittalshow您的xml时，我需要它可见。如果您根本不调用“Display（）”，布局（display2）是可见的还是不可见的？如果我不调用它visible@0X0nosugarnope. 看，我已经在axml文件中将其设置为不可见。我希望它在Display（）运行时可见。但当我启动Activity投票否决这个问题时，它是可见的，因为C#/xamarin问题的Java解决方案毫无意义

    display2.setVisibility(View.VISIBLE);

    private void Display (){
        LinearLayout display2 = FindViewById<LinearLayout> (Resource.Id.linearLayout12);        
        //LinearLayout display = FindViewById<LinearLayout> (Resource.Id.linearLayout13);           
        TextView productname = FindViewById<TextView> (Resource.Id.posttittle);
        TextView price = FindViewById<TextView> (Resource.Id.price);
        TextView weight = FindViewById<TextView> (Resource.Id.weight);


        productname.Text = Intent.GetStringExtra ("title");

        if (productname.Text == Intent.GetStringExtra ("title")) {
            display2.Visibility = ViewStates.Visible;
        } 
        else {
            display2.Visibility = ViewStates.Gone;
        }


        price.Text = Intent.GetStringExtra("price");
        weight.Text = Intent.GetStringExtra("weight");
        //display2.Visibility = ViewStates.Visible;
        productname.Visibility = ViewStates.Visible;
        price.Visibility = ViewStates.Visible;
        weight.Visibility = ViewStates.Visible;
    }
