CoordinatorLayout 使用 IndexOutOfBoundsException 使应用程序崩溃

Question

我的应用程序因CoordinatorLayout 中的onLayout 函数而崩溃（来自Crashlytics，无法在本地重现）：

由于我自己无法重现这一点，并且使用 CoordinatorLayouts 有 6 个活动，我该如何调试它？

编辑：看起来会在next support library release中修复

Answer 1

我遇到了类似的问题，降级到较旧的 Android 支持库版本 (v24.1.1) 对我有用。这似乎是库中的问题，您可以在 Android 问题跟踪器here 中查看问题。

更新 1 ：似乎它将在下一个版本的 Android 支持库 (v24.2.1) 中得到解决，感谢Daniel Rampelt 的更新

更新 2：24.2.1 已于今天发布，错误似乎已解决——至少我无法用当前版本重现它。 – PattaFeuFeu

更新 3：24.2.1 引入了新错误：post – AAverin

Answer 2

我也有同样的问题

我的问题是因为显示快餐栏 我附上了用 try catch 显示小吃条代码，现在它可以正常工作了

 /**
 * try catch becuase of SupportLibrary bug link "https://code.google.com/p/android/issues/detail?id=220762"
 *
 * @param v
 */
public void showConnectionErr(View v) {
    try {
        Snackbar b = getFailureSnackBar(v, "Bluetooth connection lost", false);
        b.setAction("RETRY", new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                new ConnectThread().execute();
            }
        });
        b.show();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
