当我从活动组调用活动时，我得到 java.lang.StackOverflowError。

以下是代码：

Intent i = new Intent(PermissionsScreen.this,DownloadActivity.class);
replaceContentView("Activity10",i);
public void replaceContentView(String id, Intent newIntent) {
View view = getLocalActivityManager().startActivity(id,newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) .getDecorView();
this.setContentView(view);
    }

当我调用不同的活动代替 DownloadActivity.class 时，我没有收到 java.lang.StackOverflowError，如图所示

Intent i = new Intent(PermissionsScreen.this,PaymentScreen.class);
replaceContentView("Activity10",i);

PaymentScreen 和DownloadActivity 的区别在于，PaymentScreen 是一个简单的活动。而 DownloadActivity 使用 asynctask 来下载文件。

是什么导致 StackOverflowError 在我启动一个活动时发生而在另一种情况下不发生？

我找不到任何明显的原因。

任何帮助表示赞赏。

根据您的堆栈跟踪，您有一个巨大的嵌套视图层次结构，它试图自行绘制。

要么它是一个非常深的层次结构，要么你以编程方式在你的内部构建\膨胀子视图ViewGroup，并最终创建一个递归视图包含。

无论哪种方式，它似乎都与您发布的代码无关，而是与有问题的活动的实际 UI 内容有关。

如果您在活动布局中没有发现问题（从堆栈跟踪中看起来很明显），请在您的问题中发布您的布局 XML 或布局代码。
