将 ButterKnife 绑定到 Dialog 失败

Question

我尝试将 ButterKnife 绑定到我使用 DialogBuilder 方法创建的 AleterDialog 并且存在这种方法 ButterKnife.bind(Object,Dialog); 但对我不起作用

import android.support.v4.app.DialogFragment;
import android.support.v7.app.AlertDialog;
public class NewUserDialogFragment extends DialogFragment {
    @Bind(R.id.textuserAccount)
    EditText textuserAccount;
    @Bind(R.id.textPassword)
    EditText textPassword;
    @Bind(R.id.nauta_domains)
    Spinner nauta_domains;
    @Bind(R.id.manualConfig)
    View manualConfig;
    @Bind(R.id.checkViewPass)
    CheckBox checkViewPass;

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        AlertDialog dialog = new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.new_user_dialog__icon)
                .setTitle(R.string.new_user_dialog_title)
                .setView(R.layout.accountlist_dialog_user_)
                .setPositiveButton(R.string.alert_dialog_create, void_OnClickListener)
                .setNegativeButton(R.string.alert_dialog_cancel, void_OnClickListener)
                .create();
      //Fails!!!!!!!
        ButterKnife.bind(this,dialog);  
    ...

错误：

Caused by: java.lang.IllegalStateException: Required view 'textuserAccount' with ID 2131624044 for field 'textuserAccount' was not found. If this view is optional add '@Nullable' annotation.
                                                                                      at butterknife.ButterKnife$Finder.findRequiredView(ButterKnife.java:140)

和 textuserAccount = (EditText) ((Dialog) dialog).findViewById(R.id.textuserAccount); 完美工作

我可以在这个 class?

中以某种方式使用 butterknife

Answer 1

您需要扩充对话框布局并将生成的 View 对象传递给 butterknife。

    view = View.inflate(getContext(), R.layout.accountlist_dialog_user_, null);
    ButterKnife.bind(this, view);

至少，这就是我在对话框中使用 Butterknife 的方式，它对我来说效果很好。

Answer 2

我能够在 DialogFragment 的 onStart 中绑定视图（类似于 this sample app），同时仍然使用 AlertDialog.Builder#setView(int) 方法：

private Unbinder unbinder;

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AlertDialog.Builder(getActivity())
            .setIcon(R.drawable.new_user_dialog__icon)
            .setTitle(R.string.new_user_dialog_title)
            .setView(R.layout.accountlist_dialog_user)
            .setPositiveButton(R.string.alert_dialog_create, void_OnClickListener)
            .setNegativeButton(R.string.alert_dialog_cancel, void_OnClickListener)
            .create();
}

@Override
public void onStart() {
    super.onStart();
    unbinder = ButterKnife.bind(this, getDialog());
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    unbinder.unbind();
}

Answer 3

一切都很完美

Dialog dialog = new Dialog(context); dialog.setContentView(R.layout.dialog_outcome); Unbinder unbinder = ButterKnife.bind(this, dialog);

将 ButterKnife 绑定到 Dialog 失败

Bind ButterKnife to Dialog fails

android
