android - Android中的手势识别

Question

我是 Android 新手，我正在开发Gestures. 我对如何识别文本有疑问。当用户绘制一个必须被识别并且必须打印在屏幕顶部的字母或数字时。我开始知道它可以通过GestureOverlayView但不知道如何实现它。

谁能帮我提供一些示例代码。

用这个

public class YourClass extends Activity implements OnGesturePerformedListener {  
  private GestureLibrary mLibrary;   
mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures);  
 if (!mLibrary.load()) {     
    finish();   
  }     
 GestureOverlayView gestures =    (GestureOverlayView)findViewById(R.id.gestures);
     gestures.addOnGesturePerformedListener(this);  
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {  
   ArrayList<Prediction> predictions = mLibrary.recognize(gesture); 
    Log.v("performed","performed");  
   // 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.equalsIgnorecase("right")){    
                       //do you thing here//       
                }
