我想创建一种用户可以选择选项的方式，如下图所示

在此处输入图像描述

现在正在做以下事情

public static class CategoriesDialogFragment extends SherlockDialogFragment {

    public static CategoriesDialogFragment newInstance(int title) {
        CategoriesDialogFragment frag = new CategoriesDialogFragment();
        Bundle args = new Bundle();
        args.putInt("title", title);
        frag.setArguments(args);
        return frag;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        int title = getArguments().getInt("title");

        return new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.alert_dialog_icon)
                .setTitle(title)
                .setMultiChoiceItems(_categories, _selections,
                        new DialogSelectionClickHandler())
                .setPositiveButton(R.string.alert_dialog_ok,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                ((MainActivity) getActivity())
                                        .doPositiveClick();
                            }
                        }).create();

        /*
         * .setNegativeButton(R.string.alert_dialog_cancel, new
         * DialogInterface.OnClickListener() { public void
         * onClick(DialogInterface dialog, int whichButton) {
         * ((MainActivity) getActivity()) .doNegativeClick(); } })
         */
    }

    public class DialogSelectionClickHandler implements
            DialogInterface.OnMultiChoiceClickListener {
        public void onClick(DialogInterface dialog, int clicked,
                boolean selected) {
            // Log.i("ME", _options[clicked] + " selected: " + selected);
        }
    }

}

但我想像图像一样添加所有选项。所以我想我将不得不建立一个自定义对话框。我是否仍然可以扩展本机 setMultiChoiceItems 以减少我对代码的处理。

您可能可以使用该类的setCustomTitle()方法AlertDialog.Builder并构建自己的标题，该标题具有标题文本以及all CheckBox，如下所示：

new AlertDialog.Builder(getActivity())
                .setIcon(R.drawable.alert_dialog_icon)
                .setTitle(title)
                .setCustomTitle(getLayoutInflater().inflate(R.layout.custom_title, null));

哪里R.layout.custom_title是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/textView1"
        style="?android:attr/textAppearanceLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Dialog title"
        android:textColor="#ffffff" />

    <TextView
        android:id="@+id/all"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="All"
        android:textColor="#ffffff" />

    <CheckBox
        android:id="@+id/checkBox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

应进行其他样式调整以使其看起来更好。但是看到整个对话框布局，您可能希望使用自定义Dialog类，该setMultiChoice()方法将不可用（但最终它很容易复制）。

我已经实现了您在图像中显示的东西。我使用的是您正在考虑使用的自定义对话。我在 xml 文件中使用了 Listview。

首先定义初始化下面的arraylist。

// Catagory Selection
    public static ArrayList<String> acceptpositionwhoesNearMe = new ArrayList<String>();
    public static String AcceptCatagotyIDWhoesNearMe = "";

下面是我使用的代码showDialog()。

public void showDialog() {
        Log.i(TAG, "Inside Show Dialog");
        final Dialog warning = new Dialog(logout_dialogue.this);
        warning.requestWindowFeature(Window.FEATURE_NO_TITLE);
        warning.setContentView(R.layout.YOUR_XML);
        warning.setCancelable(false);
        warning.getWindow().setGravity(Gravity.CENTER);

        WindowManager mWinMgr;
        mWinMgr = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
        int displayWidth = mWinMgr.getDefaultDisplay().getWidth();

        warning.getWindow().setLayout(displayWidth - 75,
                LayoutParams.WRAP_CONTENT);
        warning.setOnDismissListener(new OnDismissListener() {
            public void onDismiss(DialogInterface dialog) {
                Log.i(TAG, "Inside Dialog interface");
                // test = true;
                warning.dismiss();
            }
        });
        ListView listinterest = (ListView) warning
                .findViewById(R.id.list_catagory);
        /*
         * ArrayList<String> count = new ArrayList<String>(); count.clear();
         * count.add("Hotels"); count.add("Restaurants"); count.add("Gardens");
         * count.add("Theater");
         */
        CatagorySummaryAdapter adapter;
        adapter = new CatagorySummaryAdapter(YOUR_ACTIVITY.this,
                YOUR_ARRAYLIST_OF_CATAGORY, true);

        listinterest.setAdapter(adapter);

        Button btnOk = (Button) warning.findViewById(R.id.btn_close);
        btnOk.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                // TODO Auto-generated method stub

                String Catagory = "";
                int count = HomeActivity.acceptpositionwhoesNearMe.size();

                if (count > 0) {
                    for (int i = 0; i < HomeActivity.acceptpositionwhoesNearMe
                            .size(); i++) {

                        int pos = Integer
                                .parseInt(HomeActivity.acceptpositionwhoesNearMe
                                        .get(i));
                        if (Catagory.equals("")) {
                            Catagory = GetUserDetailsJsonParser.CategoryName
                                    .get(pos);
                            HomeActivity.AcceptCatagotyIDWhoesNearMe = GetUserDetailsJsonParser.CategoryID
                                    .get(pos);
                        } else {

                            Catagory = Catagory
                                    + ","
                                    + GetUserDetailsJsonParser.CategoryName
                                            .get(pos);
                            HomeActivity.AcceptCatagotyIDWhoesNearMe = HomeActivity.AcceptCatagotyIDWhoesNearMe
                                    + ","
                                    + GetUserDetailsJsonParser.CategoryID
                                            .get(pos);
                        }

                    }

                    Log.i(TAG, "Accept Catagory IDs WhoseNear Me"
                            + HomeActivity.AcceptCatagotyIDWhoesNearMe);

                    GetUserDetailsJsonParser.InterestedIn = HomeActivity.AcceptCatagotyIDWhoesNearMe;
                    UpdateMap = true;
                    /*
                     * startActivity(new Intent(WhosNearMe.this,
                     * BuildInukshk_4.class));
                     */
                    new GetUsersInRadiusAsyncTask().execute();

                    warning.dismiss();

                } else {
                    Toast.makeText(WhosNearMe.this,
                            "Please Select One or More Catagory", 3).show();
                }
                // test = true;

            }
        });

        warning.show();
    }

这是我的 logout_dialogue.xml：

                    }
                });

        holder.txtinterestname.setText(Count.get(pos));

        return convertView;
    }

}

尝试通过它可能会帮助你。

我还想继续使用setMultiChoiceItems()我的对话框，所以我没有创建自定义对话框，而是这样做了：

不要AlertDialog立即退货。AlertDialog.Builder首先像这样创建它：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

设置您的构建器参数：

builder.setTitle(listTitle)
.setMultiChoiceItems(allTagsArray, containsTag,
            new DialogInterface.OnMultiChoiceClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which, boolean isChecked){

然后创建AlertDialog自身调用create()。这还不会显示对话框。

AlertDialog dialog = builder.create();

然后获取ListView，添加页眉和/或页脚，然后返回。

ListView dialogList = dialog.getListView();
dialogList.addFooterView(yourHeader);
return dialog;

这也适用于@Luksprog setCustomTitle()，为您提供总共三个可自定义的空间，而无需实现自定义适配器。对于某些人来说，唯一可能的缺点是页眉和页脚随列表滚动（显然，如果列表比屏幕长，这只会有问题）。

希望这可以帮助。

重要更新：不要在复选框列表中使用标题。它会导致AlertController.java错误计算选中了哪个复选框，使其无用。仍然可以使用页脚，这在这种情况下很有用，但在我的情况下没有，所以我正在构建一个自定义对话框。
