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 );
