IllegalStateException：在使用 onActivityResult 的 onSaveInstanceState 之后无法执行此操作

Question

我是 Android 开发的新手。我有一个问题。我在最后几个小时尝试过，但我无法弄清楚这一点。如果是这样，我有一个受欢迎的问题。 IllegalStateException: Can not perform this action after onSaveInstanceState with ViewPager 但由于缺乏 Android 开发经验而失败。

代码如下：

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == 1) {
            if(resultCode == RESULT_OK) {
                MyCustomDialogFragment newPopup = new MyCustomDialogFragment();
                newPopup.setMyClickListener(MainActivity.this);
                FragmentManager fragmentManager = getSupportFragmentManager();
                newPopup.show(fragmentManager, "CashReceivePopup");  
          } 
       }
   }

这里是错误：

Answer 1

在您的 onActivityResult() 方法中执行任何 FragmentTransactions 之前，您必须先调用 super.onActivityResult(requestCode, resultCode, data)，因为该调用是 'unlocks' FragmentManager 并指出您处于执行 FragmentTransactions 的有效状态。

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // Add this line
        super.onActivityResult(requestCode, resultCode, data);

        // This all remains the same
        if (requestCode == 1) {
            if(resultCode == RESULT_OK) {
                MyCustomDialogFragment newPopup = new MyCustomDialogFragment();
                newPopup.setMyClickListener(MainActivity.this);
                FragmentManager fragmentManager = getSupportFragmentManager();
                newPopup.show(fragmentManager, "CashReceivePopup");  
          } 
       }
   }

这是一个常见问题。您有 2 个选项来处理这个问题。

您可以覆盖 show() 方法并将其内容放入 try-catch 块中

您按以下方式显示对话框

 FragmentManager fm = getSupportFragmentManager();
 MyDialog d = new MyDialog();
 FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
 ft.add(d, "dialog");
 ft.commitAllowingStateLoss();
