Question

我正在使用一个最后有线程操作的活动来初始化一个新片段。运行应用程序时没有问题。但是当从另一个窗口（例如设置）返回时，它会崩溃。

我的代码如下。请注意，实际错误是ft.commit（）。

private void preHaberler()
{
    try
    {
        new Thread(new Runnable(){
            @Override 
            public void run(){
                haberler();
            }
        }).start();
    }
    catch(Exception ex)
    {
        test(ex.getMessage());
    }
}

private void haberler()
{
    try
    {
        int sayfa = 1;
        int sayi = 10;
        int modul = -1;
        int ekModul = -1;
        HaberlerListModel[] haberler = Haberler.list(modul, ekModul, sayi, sayfa);
        final Bundle arguments = new Bundle();  
        arguments.putParcelableArray(HaberListesiFragment.ARG_HABERLER, haberler);
        arguments.putInt(HaberListesiFragment.ARG_SAYFA, sayfa);
        arguments.putInt(HaberListesiFragment.ARG_SAYI, sayi);
        arguments.putInt(HaberListesiFragment.ARG_MODUL, modul);
        arguments.putInt(HaberListesiFragment.ARG_EKMODUL, ekModul);

        runOnUiThread(new Runnable(){
            @Override 
            public void run(){
                HaberListesiFragment hlf = new HaberListesiFragment();
                hlf.setArguments(arguments);
                FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                //ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
                ft.setCustomAnimations(R.anim.enter, R.anim.exit, R.anim.pop_enter, R.anim.pop_exit);
                ft.replace(R.id.main_container, hlf);
                ft.addToBackStack("bir");
                ft.commit(); // here is the error
//
        }
        });
    }
    catch(Exception ex)
    {
        test(ex.getMessage());
    }
}

这是堆栈：

    Thread [<1> main] (Suspended (exception RuntimeException))  
        <VM does not provide monitor information>

如何克服这个问题？

非常感谢任何帮助。

您需要创建活动才能执行任何FragmentTransaction。

请尝试将您的呼叫转移到onActivityCreated方法。

Android从另一个窗口返回后崩溃
