グラフィカルなレイアウトが壊れています

Question

パレットの要素をエディタに追加できません。エディタに何も表示されず、パレットが表示されます。このメッセージは、新しく作成したプロジェクトからmain.xmlレイアウトファイルを開くときに表示されます。

The project target (Android 2.2) is still loading. 

プロセスが完了すると、レイアウトは自動的にリフレッシュされます。

また、エラーログに：

ヘルプ？

Answer 1

グラフィカルエディタのエラーが表示されず開かない理由はたくさんあるようですが、自分のカスタムデバイス設定を削除してエディタを修正しました。

グラフィカルエディタでこれを行うには、エディタに表示されているデバイスに関連するドロップダウンを開きます。たとえば、3.7インチのWVGA Nexus。 下部に「カスタムを追加...」オプションをクリックします。 の設定をポップアップに選択し、を削除してください。グラフィカルなエディタを開いた後、私のために働いた。

うまくいけば、これは他の誰かを助けてくれるでしょう。
