自定義對話框與setMultiChoiceItems

我想創建一種方式用戶可以選擇以下自定義對話框與setMultiChoiceItems

enter image description here

像圖像選項眼下正在做以下

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); 
     } 
    } 

}

，但我想添加的所有選項像圖像。所以我想我將不得不建立一個自定義的對話框。我是否仍然可以擴展原生setMultiChoiceItems，以便減少對代碼的處理。

'Builder'有一個'setCustomTitle（View）'方法。 – Luksprog

@Luksprog它需要有一個複選框。如圖中所示。所以當我點擊時，我想檢查或取消選中對話內容中的所有內容。 –

那麼爲包含'TextView'（實際標題）和'all'' CheckBox'的方法提供一個View。 – Luksprog

你也許可以使用AlertDialog.Builder類的setCustomTitle()方法，並構建自己的標題具有的標題文字，也是所有CheckBox，這樣的事情：

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>

其他風格的調整應該使它看起來更好。但看到整個對話框佈局，您可能需要使用自定義的Dialog類，因此setMultiChoice()方法將不可用（但最終很容易複製）。

類型DialogFragment中的方法getLayoutInflater（Bundle）不適用於參數（） –

@HarshaMV'getActivity（）。getLayoutInflater（）' – Luksprog

我做了上述，我實現了我的自定義標題，但我怎麼才能得到值對象？ findViewById不起作用：/ –

我已經實現了你在圖像中顯示的東西。我正在使用的是Custom Dialogue，因爲您正在考慮使用它。我在xml文件中使用了Listview。

首先定義初始化下面的數組列表。

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

下面是代碼的ShowDialog（）我已經使用。

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(); 
    }

這裏是我logout_dialogue.xml：

是不是有可能在DialogFragments中使用setMultiChoiceItems？ –

@HarshaMV：我還沒有使用SherlockDialogFragment。所以不能給你正確的建議。真對不起。 –

沒問題。你可以分享代碼做到全選，也可以不選全部。只要你提到你已經實現了這一點。我想我們可以很容易地將你的代碼移到DialogFragment –

我也想用setMultiChoiceItems()與我的對話，以保持，所以不是創建一個自定義對話框，我這樣做：

不要立即返回AlertDialog。創建AlertDialog.Builder它首先是這樣的：

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

設置你的建設者參數：

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

然後創建AlertDialog本身調用create()。這不會顯示對話框。

AlertDialog dialog = builder.create();

然後拿到ListView，添加頁眉和/或頁腳，並將其返回。

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

這也適用於@ Luksprog的setCustomTitle()給你一共有三個定製空間，而無需實現自定義適配器。對於某些人來說，唯一可能的缺點是頁眉和頁腳與列表一起滾動（顯然，如果列表比屏幕更長，這隻會產生問題）。

希望這會有所幫助。

重要更新：請勿在複選框列表中使用標題。它導致AlertController.java錯誤地計算了哪個複選框被打勾，使其無效。一個頁腳仍然可以使用，在這種情況下非常有用，但在我的情況下不是這樣，所以我正在構建一個自定義對話框。
