Question

当单击Cardview时，我的应用程序将显示开始活动，该活动将在Recycler视图中显示附近的地方。但是，每当我单击cardview时，都会出现以下错误。当我在NeighborhoodActivity.java中注释public class StackX { private final int maxSize; private final long[] stackArray; private int top; public StackX(final int size) { maxSize = size; stackArray = new long[maxSize]; top = -1; } /** Puts an item on top of the stack. */ public void push(final long value) { if (isFull()) { throw new UnsupportedOperationException("Stack is full"); } stackArray[++top] = value; } /** Takes an item from top of the stack. */ public long pop() { if (isEmpty()) { throw new UnsupportedOperationException("Stack is empty"); } return stackArray[top--]; } /** Peeks an item at top of the stack. */ public long peek() { return stackArray[top]; } /** Returns {@code true} if stack is empty. */ public boolean isEmpty() { return top == -1; } /** Returns {@code true} if stack is full. */ public boolean isFull() { return top == maxSize - 1; } }时，程序不会崩溃。这是可能的，因为nearByPlace（“ restaurant”）也使用相同的ID，我该如何解决

ItemOneFragment.Java

        stackX.push(20);
        stackX.push(40);
        stackX.push(60);
        stackX.push(80);

        removeDownTo(stackX, 60);

        // Prints remaining elements
        while (!stackX.isEmpty()) {
            System.out.println(stackX.pop());
        }

是的，您已经为自己的活动正确实施了onPause，但没有为您的Fragment实施。

在Fragment内的init方法中，创建一个新的GoogleApiClient。这与您的Activity中的代码不同，在onPause中，您正确地实现了onPause。

因此，解决该问题的方法应该是为您的Fragment实现//toggle hitbox on and off public void EnableHitbox(bool enabled) { coll.enabled = enabled; Debug.Log("Hitbox enabled: " + enabled); } //check for collisions with hurtboxes private void OnTriggerEnter2D(Collider2D collision) { if (collision.transform.tag == "Hurtbox" && collision.transform.parent.transform.tag == "Enemy") { Debug.Log("Hitbox hit enemy"); } }。

我希望这能解决您的问题

尽管实现了onPause（），但已经管理了ID为0的GoogleApiClient错误
