Android：残念なことに、Appが停止していますレイアウトの問題

-1

私は自分のアクティビティで作成したクラスを呼び出そうとしていますが、残念ながら、自分のアクティビティを送信するはずのボタンをクリックすると、私はそれをデバッグしようとしており、常にsetContentView（R.layout.activity_draw_triangle）行で停止します。私はオンラインで見て、利用可能なさまざまな回答で問題を解決しようとしましたが、何もしません。ここでAndroid：残念なことに、Appが停止していますレイアウトの問題

遅れて申し訳ありません投稿しました^^ – IHaveProblemsCoding101

DrawingViewにはコンストラクタDrawingView（Context、AttributeSet）が必要です。これは、XMLから膨張するときに呼び出されるものです（さまざまなパラメータが属性セットです）。また、テーマ作成の場合にのみ、DrawingView（Context、AttributeSet、int）を用意する必要があります。

ありがとう、あなたの答えをありがとう！私は属性セットが必要だと思った。しかし、私は次の行を呼び出すとき： 'DV =新しいDrawingView（この）;私は、は、だから私はこれらを考慮することは、XMLのパラメータを変更する必要があり、変数attrsにに値として置くために何を知らない' を私の属性はあなたの答えに基づいて設定されていますか？ – IHaveProblemsCoding101

実際にDrawingViewコンテキスト属性セットはDrawActivityに適用できないと言われています – IHaveProblemsCoding101

あなたはそれを間違ったファイルに入れています。それはDrawingViewクラスに入る必要があります。 –
