Android DialogFragment是空白的

Question

我在创建对话框时遇到问题.它看起来确实如此,但它内部空洞,只显示一个空白框.

对话类:

public class SomeDialog extends DialogFragment{

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

    builder.setView(inflater.inflate(R.layout.somelayout, null));

    return super.onCreateDialog(savedInstanceState);
}
}

在活动中,创建对象并调用show方法:

SomeDialog obj = new SomeDialog();
obj.show(getFragmentManager(), "randomtag");

Answer 1

return super.onCreateDialog(savedInstanceState);

您正在返回父方法.你应该归还自己的.改成 :

 return builder.create();
