身振りを認識するAndroid

Question

こんにちは私はユーザーが画面上にジェスチャーを描き、画像ビュー内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比較します。私はあなたがドン何かが」そこだ画像が表示され、ユーザーはそれを画像で表示されるものとは別の何かを描画するたびに、それがうまくどのように行われると言うことです私はこの問題を解決することができますか？...とにかくここにコード

だ

Answer 1

"I".equals(prediction)は、文字列を完全に分離したオブジェクトタイプandroid.gesture.Predictionに等しいと言っているため、間違っています。

私はしばらく前にこれに関連するカレンダーのために書いた、これを引くことができたいくつかのコードに掘っ

：

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(); 
      } 
     } 

私は実際に私がロードジェスチャーライブラリを作成するには、Googleのサンプルアプリケーションのいずれかを使用mLibraryに;これが何らかの形で役立つことを願っています...
