问题的DialogFragment膨胀的自定义视图AlertDialog [英] Problem inflating custom view for AlertDialog in DialogFragment

问题描述

我试图创建一个 DialogFragment 用在 AlertDialog 自定义视图。这种观点必须从XML充气。在我的 DialogFragment I类有：

I'm trying to create a DialogFragment using a custom view in an AlertDialog. This view must be inflated from xml. In my DialogFragment class I have:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AlertDialog.Builder(getActivity())
        .setTitle("Title")
        .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, null))
        .setPositiveButton(android.R.string.ok, this)
        .setNegativeButton(android.R.string.cancel, null)
        .create();
}

我已经尝试过其他的通货膨胀的方法 .setView（）如：

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getView(), false))

和

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getTargetFragment().getView(), false))

设置在片段中的目的片段后，即显示该对话框。

After setting the target fragment in the fragment that is showing this dialog.

所有这些企图夸大我的自定义视图导致以下异常：

All of these attempts to inflate my custom view result in the following exception:

而如果我尝试使用 DialogFragment 的 getLayoutInflator（捆绑）是这样的：

.setView(getLayoutInflater(savedInstanceState).inflate(R.layout.dialog, null))

我收到了的StackOverflowError 。

有谁知道如何膨胀的自定义视图的 AlertDialog 在 DialogFragment ？

Does anyone know how to inflate a custom view for an AlertDialog in a DialogFragment?

推荐答案

第一个错误行给我的暗示，这是关系到你如何创建你的对话 - 而不是对话本身

The first error line gives me the hint that this is related to how you are creating your dialog - not the dialog itself.

您自动创建的对话框（这可能意味着这个被称为意见之前，都设置了），或者响应按钮点击？我最初有问题，因为实例化为了碎片。

Are you creating the dialog automatically (which could mean this gets called before the views are all set up) or in response to a button click? I initially had problems with fragments due to instantiation order.

我用同样的code设置视图为你，我的结果有效。我切出的其它设置，使这个看起来干净，但它的作品有或没有它。

I used the same code to set the view as you have, and my result works. I cut out the other setup to make this look cleaner, but it works with or without it.

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

    View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_layout, null);
    builder.setView(view);

    return builder.create();
}
