如何设置DialogFragment的标题? [英] How to set the title of DialogFragment?

问题描述

这应该是一个简单的任务，但是由于某种原因，我可以找到一种方法来设置 DialogFragment . (我正在使用onCreateView重载设置对话框的内容.)

This should be a simple task, but for some reason I can find a way to set the title of a DialogFragment. (I am setting the dialog contents using onCreateView overload).

默认样式保留了标题的位置，但是我找不到DialogFragment类上的任何方法来设置它.

The default style leaves a place for the title, but I can't find any method on the DialogFragment class to set it.

使用onCreateDialog方法设置内容时以某种方式神奇地设置了标题，所以我想知道这是设计使然，还是使用onCreateView重载时设置它的特殊技巧.

The title is somehow magically set when the onCreateDialog method is used to set the contents, so I wonder if this is by design, or there is a special trick to set it when using the onCreateView overload.

推荐答案

您可以使用getDialog().setTitle("My Dialog Title")

就像这样:

public static class MyDialogFragment extends DialogFragment {
    ...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Set title for this dialog
        getDialog().setTitle("My Dialog Title");

        View v = inflater.inflate(R.layout.mydialog, container, false);
        // ...
        return v;
    }
    // ...
}
