作物のキャンセルイベントを検出する

Question

私はイメージクロッピング機能とその実行中の罰金を開発しました。 From here 今、私はトリミング時にキャンセルイベントを処理する必要があります。2つのボタンが最初にsaveとcancelクロッピングページにあります。私はクリックリスナーを見つけようとしましたが、失敗しました。 Intent intent = new Intent("com.android.camera.action.CROP");機能を使用するので、私はそれを処理することができますので、私は自分のカスタムコードを発射することができますので、私はlistnerを見つけられません。ここ

は私のコードです：（ MainActivity）
