C# 结束活动时,将产品保存在篮子中
当我从产品列表中添加产品时,我有篮子活动 添加属性的代码C# 结束活动时,将产品保存在篮子中,c#,android,xamarin,mono,C#,Android,Xamarin,Mono,当我从产品列表中添加产品时,我有篮子活动 添加属性的代码 add.Click += delegate { var intent = new Intent (this, typeof(CartActivity)); intent.PutExtra ("title", (string)(firstitem ["post_title"])); intent.PutExtra ("price", (string)(firstitem ["price"] +
add.Click += delegate {
var intent = new Intent (this, typeof(CartActivity));
intent.PutExtra ("title", (string)(firstitem ["post_title"]));
intent.PutExtra ("price", (string)(firstitem ["price"] + " грн"));
intent.PutExtra ("weight", (string)(firstitem ["weight"] + "г"));
StartActivity (intent);
};
productname.Text = Intent.GetStringExtra("title");
price.Text = Intent.GetStringExtra("price");
weight.Text = Intent.GetStringExtra("weight");
接收属性代码
add.Click += delegate {
var intent = new Intent (this, typeof(CartActivity));
intent.PutExtra ("title", (string)(firstitem ["post_title"]));
intent.PutExtra ("price", (string)(firstitem ["price"] + " грн"));
intent.PutExtra ("weight", (string)(firstitem ["weight"] + "г"));
StartActivity (intent);
};
productname.Text = Intent.GetStringExtra("title");
price.Text = Intent.GetStringExtra("price");
weight.Text = Intent.GetStringExtra("weight");
我试着停下来
namespace MurakamiKiev
{
[Activity(Label = "Murakami", Icon = "@drawable/logo", Theme = "@android:style/Theme.Black.NoTitleBar", ScreenOrientation = ScreenOrientation.Portrait)]
public class CartActivity : Activity
{
protected override void OnPause()
{
base.OnPause();
但当我运行“活动”时,我出现了黑屏您是否在OnCreate()中调用了SetContentView() 像这样
namespace MurakamiKiev
{
[Activity(Label = "Murakami", Icon = "@drawable/logo", Theme = "@android:style/Theme.Black.NoTitleBar", ScreenOrientation = ScreenOrientation.Portrait)]
public class CartActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.YourLayout);
}
}
}
可能重复的
