修复StackOverflow错误

Question

我已经开发了一个应用程序，其中我有4个选项卡A，B，C，D。每个选项卡都包含一个活动。在第四个选项卡D中，我添加了一个ActivityGroup，在其中我还有3个活动X，Y，Z.In第四个选项卡，我在其中添加了活动组I StackOverflow error.Please帮助我解决此错误。

这是我的stackTrace:--

请帮帮我，...I我对安卓非常陌生。

Answer 1

我想你在某个地方有一个无限循环。

您可能已经在层次结构中的某个位置添加了两次视图的相同实例，现在您已经有了一个循环。

解决这个问题。然后修改你的布局。我看不出有这么复杂的布局的理由。

Answer 2

我已经搜索了所有的谷歌，但没有找到一个解决方案。然后我刚刚想到了这个想法，它完美地工作在我的旧三星Galaxy Nexus和沃达丰VF695！

这是我在非常深的布局的根FrameLayout中的技巧：

public class StackFrameLayout extends FrameLayout {
    private boolean stackOverflow;

    @Override
    public void draw(final Canvas canvas) {
        if (stackOverflow) {
            stackDraw(canvas);
        } else {
            try {
                super.draw(canvas);
            } catch (StackOverflowError e) {
                stackOverflow = true;
                stackDraw(canvas);
            }
        }
    }

    public void stackDraw(final Canvas canvas) {
        Thread thread = new Thread(getContext().getMainLooper().getThread().getThreadGroup(), new Runnable() {
            @Override
            public void run() {
                StackFrameLayout.super.draw(canvas);
            }
        }, "draw-thread", 2000000);
        thread.start();
        try {
            thread.join();
        } catch (InterruptedException e1) {
            e1.printStackTrace();
        }
    }
}

因此，基本上我将复杂的绘制方法传递到一个堆栈较大的线程中。因此，调用的方法堆栈将停止增加该点。然后，UI线程等待绘制线程完成其工作，然后继续确保它像在UI线程上运行一样按顺序绘制。
