尝试为DialogFragment中的AlertDialog充气自定义布局时出现StackOverflowError

Question

我正在尝试使用Builder并设置自定义视图来创建AlertDialog.当我尝试给onCreateDialog里面的视图充气时,我得到一个StackOverflowError ..

这是代码,直到它循环回onCreateDialog:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle(R.string.enter_time);

    LinearLayout outerLayout = (LinearLayout) getLayoutInflater(savedInstanceState)
            .inflate(R.layout.time_entry_dialog, null);
    ...
}

这是LogCat输出:

...etc

编辑:我在DialogFragment.getLayoutInflater()的源代码中找到了这一行:

mDialog = onCreateDialog(savedInstanceState);

那么..如果我无法在onCreateDialog中获取LayoutInflator而不会导致无限递归,我该如何为自定义AlertDialog提供视图？

Answer 1

如果发现问题.DialogFragment.getLayoutInflater()包含一个调用onCreateDialog(),因此onCreateDialog()从内部调用getLayoutInflater()会创建一个无限循环.

我在这个答案中找到了解决方案:https://stackoverflow.com/a/10585164/2020340

我不确定这是不是很好的形式,因为它看起来并不像,但我更换了

getLayoutInflater(savedInstanceState)

同

getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

编辑:他们是一样的.有关详细信息,请参阅此答案:https://stackoverflow.com/a/20995083/2020340
