こんにちは、ユーザーが画面上でジェスチャーを描画し、imageview の画像が描画されたジェスチャーと同じであるかどうかを比較し、「よくやったかもう一度やり直してください」などのメッセージを表示するアプリを構築しています。私の問題は、画像が表示されるたびにユーザーは、画像に表示されるものとは異なるものを描きます

"I".equals(prediction)完全に別のオブジェクト type で文字列 equals を呼び出しているため、この言い方が間違っていると確信していますandroid.gesture.Prediction。

しばらく前にこれに関連するカレンダー用に書いたコードを掘り下げて、これを引き出すことができました：

    public void onGesturePerformed(GestureOverlayView overlay,
            Gesture gesture) {
        ArrayList<Prediction> predictions = mLibrary.recognize(gesture);

        // We want at least one prediction
        if (predictions.size() > 0) {
            Prediction prediction = predictions.get(0);
            // We want at least some confidence in the result
            if (prediction.score > 1.0) {
                if (prediction.name.equals("gest_right")) {
                    // Toast.makeText(this, "previous month",
                    // Toast.LENGTH_SHORT).show();

                    userMonth.set(Calendar.DAY_OF_MONTH, 1);
                    userMonth.add(Calendar.DATE, -1);

                    // goingForward = false;
                } else {
                    // Toast.makeText(this, "next month",
                    // Toast.LENGTH_SHORT).show();

                    userMonth.set(Calendar.DAY_OF_MONTH, 1);
                    userMonth.add(Calendar.DATE, userMonth
                            .getActualMaximum(Calendar.DAY_OF_MONTH));

                    // goingForward = true;
                }
                updateCalendarUI();
            }
        }

私は実際にGoogleのサンプルアプリの1つを使用してジェスチャーライブラリを作成し、それをmLibraryにロードしました。これが何らかの形で役立つことを願っています...
