android 定义手势

手势

1) 定义手势

导入GestureBuilder   (android sample project)

mnt/sdcard/gestures

2) 识别手势

a) 拷贝到res\raw\  

b) layout   新增GestureOverlayView，用来做布局

c) 加载手势库

final GestureLibrary library = GestureLibraries.fromRawResource(this, R.raw.gestures);

library.load();

d) 识别手势

GestureOverlayView overlayView = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);

OnGesturePerformedListen er listener = new OnGesturePerformedListen er()

{

@Override

public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture)

{

ArrayList recognizeList = library.recognize(gesture);

Prediction prediction = recognizeList.get(0);

if (prediction.score >= 5)

{

if ("exit".equals(prediction.name))

{

finish();

}

else if ("open".equals(prediction.name))

{

checkBox.setChecked(true);

}

}

}

};

overlayView.addOnGesturePerformedLis tener(listener );
