Xamarinアンドロイドコンパイルされたアプリが空です

Question

私はVS 2015 EnterpriseとXamarinで新しいアンドロイドプロジェクトを作成し、ウィジェットを追加しました。私は、プロジェクトをビルドして実際のアンドロイド4.4デバイスで実行するたびに空のフォームを取得しています。アンドロイド4.1を使用してコンパイルします。ここ

はmain.axmlコードです：

Answer 1

コンテンツは次のようなレイアウトになります。

[Activity(Label = "Chasp", MainLauncher = true, Icon = "@drawable/icon")] 
public class MainActivity : Activity 
{ 
    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 
     SetContentView (Resource.Layout.Main); 
    } 
} 

これはあなたのAXMLファイルをロードし、コンテンツとして設定します。

これはデフォルトでは行われない理由は、UIを構築する方法が複数あるからです。コードで定義することもできます。おそらくこのデフォルトコードは別のプロジェクトテンプレートにあります。とにかく、いつでもすぐにこれを忘れることはありません！あなたの `ベースの後に`;

Answer 2

あなたは私はあなたがまだ `SetContentView（Resource.Layout.Main）のようなコンテンツとしてレイアウトを設定する必要があると思う

base.OnCreate(bundle); 
SetContentView (Resource.Layout.Main);
