Java ACTION\u MOVE每次在OnTouch中调用时都返回相同的值

java android

Java ACTION\u MOVE每次在OnTouch中调用时都返回相同的值,java,android,ontouch,Java,Android,Ontouch,我试图调用一个方法，每次调用ACTION\u MOVE时都用不同的值更新tts元素。但是，它每次调用时都返回相同的值。respondCoordinates（v）方法有一个if语句来更改值 public boolean onTouch(View v, MotionEvent event) { //_gestureDetector.onTouchEvent(event); int eventAction = event.getAction(); // you may ne

如果（（iTo>=0）&&（iTo=8）&（iTo=16）&&（iTo=24）&（iTo=32）&（iTo=40）&（iTo=48）&（iTo=56）&（iTo这需要检查，但我相信，如果你在一个动作之前离开一个视图，你仍然会得到该视图的一个动作，因此你的视图v始终是你的动作之前的视图，即使你继续另一个动作

这可能是预期的行为

我想他们可能会证实这一点。不过，他们的解决方案可能不适合您的情况，因为您将获得您所接触的所有视图的输出，而不仅仅是当前视图的输出


这是一个问题，但我认为解决方案是在网格上有一个监听器，而不是在单元格上，并找出您从x和y接触的单元格。
我认为我正确理解了这个问题。您假设传递给
onTouch
的
视图是棋盘上64个视图之一，但事实并非如此e
View
传递给
onTouch
是您将
OnTouchListener
设置为打开的
视图。在本例中，它是棋盘本身

相反，您应该使用
MotionEvent
的坐标来查找单个工件的索引


private int mLastChildIndex = -1;

public boolean onTouch(View view, MotionEvent event) {
    int x = (int) event.getRawX();
    int y = (int) event.getRawY();

    switch(event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            mLastChildIndex = getChildIndex((ViewGroup) view, x, y);
            playNotificationForIndex(mLastChildIndex);
            break;
        case MotionEvent.ACTION_MOVE:
            int currentIndex = getChildIndex((ViewGroup) view, x, y);
            if (currentIndex != mLastChildIndex) {
                playNotificationForIndex(currentIndex);
                mLastChildIndex = currentIndex;
            } break;
        case MotionEvent.ACTION_UP:
            performClickForIndex(mLastChildIndex);
            mLastChildIndex = -1;
            break;
    }

    return true; // This method eats all MotionEvent actions for the View
}

private int getChildIndex(ViewGroup viewGroup, int x, int y) {
    for (int i = 0; i < viewGroup.getChildCount(); i++) {
        View child = viewGroup.getChildAt(i);

        int[] coordinates = new int[2];
        child.getLocationOnScreen(coordinates);

        Rect bounds = new Rect(coordinates[0], coordinates[1],
                coordinates[0] + child.getWidth(), coordinates[1] + child.getHeight());
        if (bounds.contains(x, y)) {
            return i;
        }
    } return -1;

我应该注意，action\u down每次都会生成正确的值，因此它与我创建的方法无关。看起来它与
respondCoordinates（）完全相关
方法。您提到
操作_DOWN
生成正确的值，但是正确的值是什么？
x
和
y
？但是
响应坐标（）
方法不采用
x
和
y
坐标，而是采用
视图
；因此，如果该方法产生了错误的值，似乎一定是它导致了问题。我建议发布
响应坐标（）
method，并更深入地了解您正试图实现的目标。@Bryan我已附上响应坐标（v）代码。我想做的是给屏幕上的不同按钮视图分配一个字母、数字和片段。然后将其返回到onTouch，以便用户可以在屏幕上拖动手指，它将读出不同的
