我正在尝试使用手势构建器在我的应用上接收上/下和左/右手势。我按照这里的指南(http://www.vogella.com/articles/AndroidGestures/article.html),它似乎工作,但没有完全响应手势正确。它在显示屏上左右显示为亮黄色(找到手势),但当Toast
创建弹出窗口以显示手势的名称时,它会显示右/上/下全部被识别或左/上/下来了。此外,它无法将实际滑动上下识别为有效手势(叠加时淡出黄色)。
我尝试过多次使用Gesture Builder重建Gesture库,以防出现错误,但似乎没有。
正在使用的代码与上面的链接相同。
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
gTap = new GestureDetector(this,(android.view.GestureDetector.OnGestureListener) this);
//Remove title bar
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
//Define textView
textView1 = (TextView) findViewById(R.id.textView1);
textView2 = (TextView) findViewById(R.id.textView2);
textView3 = (TextView) findViewById(R.id.textView3);
textView4 = (TextView) findViewById(R.id.textView4);
GestureOverlayView gestureOverlayView = new GestureOverlayView(this);
View inflate = getLayoutInflater().inflate(R.layout.main, null);
gestureOverlayView.addView(inflate);
gestureOverlayView.addOnGesturePerformedListener(this);
gestureLib = GestureLibraries.fromRawResource(this, R.raw.gestures);
if (!gestureLib.load()) {
finish();
}
setContentView(gestureOverlayView);
//Load font file
Typeface type = Typeface.createFromAsset(getAssets(),"fonts/optima.ttf");
//Set various textViews to font
textView1.setTypeface(type);
textView2.setTypeface(type);
textView3.setTypeface(type);
textView4.setTypeface(type);
prevPass = "Memorable";
}
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
ArrayList<Prediction> predictions = gestureLib.recognize(gesture);
for (Prediction prediction : predictions) {
if (prediction.score > 1.0) {
Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT)
.show();
}
}
}
