添加GestureOverlayView我SurfaceView类，如何添加，查看层次？ [英] Adding GestureOverlayView to my SurfaceView class, how to add to view hierarchy?
问题描述
我被告知在后面的答案，我要补充我在code创建我的看法层次的GestureOverlayView，我不是100％，如何做到这一点。下面是完整的原来的问题。
I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
我希望我的游戏能够识别手势。我有我做了一个OnDraw中吸取我的精灵这个漂亮的SurfaceView类，我有一个线程，多数民众赞成在运行它来调用OnDraw的等等。
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
这一切的伟大工程。
我想给GestureOverlayView添加到这一点，它只是不工作。最后砍死它不会崩溃，但是这是我
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
public class Panel extends SurfaceView implements SurfaceHolder.Callback, OnGesturePerformedListener
{
public Panel(Context context)
{
theContext=context;
mLibrary = GestureLibraries.fromRawResource(context, R.raw.myspells);
GestureOverlayView gestures = new GestureOverlayView(theContext);
gestures.setOrientation(gestures.ORIENTATION_VERTICAL);
gestures.setEventsInterceptionEnabled(true);
gestures.setGestureStrokeType(gestures.GESTURE_STROKE_TYPE_MULTIPLE);
gestures.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
//GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
}
...
...
onDraw...
surfaceCreated(..);
...
...
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) {
// Show the spell
Toast.makeText(theContext, prediction.name, Toast.LENGTH_SHORT).show();
}
}
}
}
该onGesturePerformed永远不会被调用。他们的例子在XML中GestureOverlay，我不使用，我的活动很简单：
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
Panel p = new Panel(this);
setContentView(p);
}
所以我在有点缺少的部分这里信息的损失，它不叫onGesturePerformed和漂亮的pretty的黄色你是画一个手势一直没有出现。
So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.
推荐答案
这是一个重大的痛苦，但我终于想通了解决方案。我们绝对在这个任何地方没有很好的在线文档。我终于得到它通过使用一种叫做的FrameLayout，然后添加两个surfaceview和手势观点有工作的工作。一旦你这样做，你设置的FrameLayout作为内容视图。
This was a major pain but I finally figured out the solution. There is absolutely no good documentation on this anywhere online. I finally got it work work by using something called a "FrameLayout" and then adding both the surfaceview and the gesture view there. Once you do that, you set the FrameLayout as your content view.
不幸的是，RomanGuy提供的上述方案似乎并没有工作（或可能的话，我只是无法得到它的工作）的一些原因。有无.addView（）函数可用于SurfaceView类像有一个常规视图。该函数存在ViewGroups和做工精细上以外的任何其他surfaceview我想加入的手势。
Unfortunately, the above solution offered by RomanGuy didn't seem to work (or possibly, I just couldn't get it to work) for some reason. There is no .addView() function available for the SurfaceView class like there is for a regular view. That function exists for ViewGroups and will work fine for adding gestures on anything other than a surfaceview I think.
您的活动必须实现OnGesturePerformedListener接口为此工作。
Your activity must implement the OnGesturePerformedListener interface for this to work.
