我正在尝试通过使用生成器并设置自定义 View 来创建AlertDialog。当我尝试在onCreateDialog内填充 View 时,出现StackOverflowError。
这是直到循环回到onCreateDialog的代码:
@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的输出:

...etc
编辑:我在DialogFragment.getLayoutInflater()的源代码中找到了这一行:
mDialog = onCreateDialog(savedInstanceState);
所以..如果在不引起无限递归的情况下无法在onCreateDialog内获取LayoutInflator,如何为自定义AlertDialog填充 View ?
最佳答案
如果发现问题。 DialogFragment.getLayoutInflater()包含对onCreateDialog()
的调用,因此从onCreateDialog()
中调用getLayoutInflater()
会创建一个无限循环。

我不确定这是否是一种好的形式,因为它看起来并不是真的,但是我将其替换
getLayoutInflater(savedInstanceState)
与
getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
编辑:它们是相同的。有关详细信息,请参见此答案:https://stackoverflow.com/a/20995083/2020340
