1 个 TAB 下的多个活动，更改活动时崩溃

发布于 2025-01-06 07:48:29 字数 2052 浏览 4 评论 0原文

我在一个选项卡下有 2 个简单的活动（每个活动托管 1 个按钮的相对布局）。它们中的每一个都具有彼此的链接，因此您可以从一项活动转到另一项活动（所有操作都在同一选项卡下进行）。程序在第三次循环后崩溃（第一个活动 - 第二个 - 第一个 - 第二个 - 第一个 - 第二个）。

我使用以下代码从一个活动转到另一个活动：

Tabs s = (Tabs) getParent();
Intent myIntent = new Intent(getApplicationContext(), Map.class);
View view = s.getLocalActivityManager().startActivity("map",
    myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
setContentView(view);

无论我在活动中拥有什么布局，基本上它仍然会在每个第三个循环中崩溃。

我没有其他想法，除了 android 将此导航（从同一个选项卡下的 1 个活动到另一个活动）解释为不定式循环？这基本上是用户所做的，而不是我正在编程的循环。

这是android的bug还是我做错了什么？

我收到此错误：

编辑： 好的，我知道为什么会出现这个错误。每次我从一项活动转到另一项活动时，我都会创建新的意图并开始新的活动。情况可能就是这样。但我怎样才能重用它们呢？如果我尝试重用该视图，则会收到此错误：

02-17 13:14:03.429: E/AndroidRuntime(5374): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

原文

I have 2 simple activities (relative layouts hosting 1 button each) under one tab. Each of them has a link to each other so you can go from one activity to another (everything works under the same tab). The program crashes after the 3rd loop (1st activity - 2nd - 1st - 2nd - 1st - 2nd).

I go from one activity to another with the following code:

Tabs s = (Tabs) getParent();
Intent myIntent = new Intent(getApplicationContext(), Map.class);
View view = s.getLocalActivityManager().startActivity("map",
    myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
setContentView(view);

It doesn't matter what layouts I have in the activities, basically it still crashes every 3rd loop.

I have no other ideas except that android interprets this navigation (from 1 activity to another under the same tab) as an infinitive loop? Which basically users does, not a loop that is being programmed by me.

Is it some android bug or I am doing something wrong?

I am getting this error:

EDIT:
OK, I have an idea why this error appears. Every time I go from one activity to another I'm creating new Intent and starting new Activity. That might be the case.
But how can I reuse them? If I try to reuse the view I get this error:

02-17 13:14:03.429: E/AndroidRuntime(5374): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
