初めてビットマップをクリックするとビットマップが変更されますが、他をクリックすると例外が表示され、ビットマップは変更されません。私はビットマップのどれかをクリックすると、他のビットマップによって変更されてしまいます。誰かが私を助けてくれないなら、どうすればいいですか？ビットマップ上でイベントをクリックすると例外が発生します

そのためにそのbitmapField1.setBitmap(bitmapField6);ようなあなたのイメージをreplce何例外あなたが得るのですか？ – BBdev

例外：マネージャ。置き換え：newFieldは既にマネージャーを持っています – Amar

HorizontalFieldmanagerのように置き換えないでくださいhfm.replace(bitmapField1, bitmapField6);。ただ、
