android - DialogFragment 和强制显示键盘

Question

我的 DialogFragment 有问题。所以为了创建我的 View ，我使用了 android 博客上描述的方法。这是我的 DialogFragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    final View myLayout = inflater.inflate(R.layout.dialog_connect, null);

    edit = (EditText) myLayout.findViewById(R.id.password_edit);
    edit.requestFocus();
    getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);

    return myLayout;
}

如果我使用 onCreateView()，它可以工作，但我想创建一个 AlterDialog 并执行此操作，我有以下代码:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout
    builder
           .setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    callback.onYesConnectClick(edit.getText().toString());
                }
            })
            .setNegativeButton(R.string.refuse, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    callback.onNoConnectClick();
                }
            });

    return builder.create();
}

如果我从 onCreateView() 注释代码，应用程序可以工作，但我无法强制显示键盘，如果我取消注释 onCreateView()，我会崩溃。这是堆栈跟踪:

所以我的问题 ==> 我可以使用 AlertDialog 并在对话框出现时显示键盘吗？

Answer 1

在您的对话框 fragment 中覆盖 onActivityCreated 并将 getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE); 放在那里
