使用setMultiChoiceItems的自定义对话框
我想创建一种方式，用户可以选择如下图所示的选项
现在正在做以下
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);
}
}
}
但我想添加像图像一样的所有选项。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，以便减少我对代码的处理。

您可以使用AlertDialog.Builder类的setCustomTitle()方法构建自己的标题，其中包含标题文本以及 all CheckBox，像这样：
new AlertDialog.Builder(getActivity())
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(title)
.setCustomTitle(getLayoutInflater().inflate(R.layout.custom_title, null));
其中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>
应该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，setMultiChoice()方法将无法使用（但最终将很容易复制）。

我已经实现了你在图像中显示的东西。我所使用的是您想要使用的自定义对话。我在xml文件中使用了Listview。
首先定义初始化以下的arraylist。
// Catagory Selection
public static ArrayList<String> acceptpositionwhoesNearMe = new ArrayList<String>();
public static String AcceptCatagotyIDWhoesNearMe = "";
以下是我使用的代码 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 ：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/edittext_back_final"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_height="wrap_content" >
<com.inukshk.CustomTextViewBold
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:text="Interested in"
android:textColor="#3C3C3C"
android:textSize="18sp"
android:textStyle="bold" />
</LinearLayout>
<ListView
android:id="@+id/list_catagory"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:layout_weight="1"
android:cacheColorHint="#00000000"
android:divider="@android:color/transparent" >
</ListView>
<Button
android:id="@+id/btn_close"
android:layout_width="99dp"
android:layout_height="40dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="10dp"
android:background="@drawable/btn_back_final"
android:text="CLOSE"
android:textColor="#ffffff"
android:textSize="16dp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>

我还想继续在我的对话框中使用setMultiChoiceItems()，所以我没有创建自定义对话框，而是这样做：
请勿立即返回AlertDialog。首先创建AlertDialog.Builder，如下所示：
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
设置构建器参数：
builder.setTitle(listTitle)
.setMultiChoiceItems(allTagsArray, containsTag,
new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked){
然后创建AlertDialog本身，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@Lacksprog的setCustomTitle()，总共有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一起滚动（如果列表长于屏幕，这只会有问题。）
希望这有帮助。
重要更新：
不要在复选框列表中使用标题。它导致AlertController.java错误计算勾选了哪个复选框，使其无效。仍然可以使用页脚，这在这种情况下很有用，但在我的情况下不行，所以我正在构建一个自定义对话框。
