Question

在Android上运行时，我们的LibGdx项目在恢复时崩溃。

以下跟踪显示出现了什么问题。但无法弄清楚如何处理这个问题。

以下是AndroidInput.java的第561行的代码段：

            if (keyCode == Keys.BUTTON_CIRCLE) {
                if (keys[Keys.BUTTON_CIRCLE]) {
                    keyCount--;
                    keys[Keys.BUTTON_CIRCLE] = false;
                }
            } else {
                if (keys[e.getKeyCode()]) { // Line 561
                    keyCount--;
                    keys[e.getKeyCode()] = false;
            }

keys数组有256个条目，因此Libgdx不会期望一个大到1026的密钥代码。

Answer 1

在第561行中，if语句有一个数组，当if语句编码执行时，你得到的是keycode作为索引变量，这可能导致数组越界，就像Logcat所说的那样。如果这导致问题，请尝试更改它，看看它是否解决了问题。

第561行中的 if语句使用 else 语句执行。如果第一个 if 是 false 。验证您是否可以更改该行中的代码并查看这是否真的导致崩溃，我不知道 e 对象的含义是什么，因为您没有在代码中发布他的工作内容

LibGdx安卓游戏在恢复时因奇数键码而崩溃（1026）
