在alertDialog

Question

我給陣列選擇通過警告對話框我想禁用選擇多個選項，如果數組滿禁用複選框項目

我已經能夠停止添加項目陣列到達極限，但不能後禁用複選框

AlertDialog.Builder builder=new AlertDialog.Builder(this); 
View view=inflater.inflate(R.layout.dialog_genre,null,false); 
builder.setView(view).setTitle("Select Genres"); 

builder.setMultiChoiceItems(array, checkedGenres, new DialogInterface.OnMultiChoiceClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
      if(isChecked) { 
       if (!selectedgenre.contains(String.valueOf(which))) 
        if(selectedgenre.size()<5) 
       { 
        selectedgenre.add(String.valueOf(which)); 
        checkedGenres[which]=true; 
       } 
       else{ 
         Toast.makeText(getApplicationContext(),"you can't add more genres",Toast.LENGTH_LONG).show(); 
        } 
      } 
      else if (selectedgenre.contains(String.valueOf(which))) 
      { 
      selectedgenre.remove(String.valueOf(which)); 
      checkedGenres[which]=false; 
     } 
    } 
}

好吧，我已經解決了這個問題，兩天後我才知道禁用複選框漫長而忙碌的過程，但我們可以禁止的選擇，這就是我想做的事。這裏是我的解決方案

builder.setMultiChoiceItems(array, checkedGenres, new DialogInterface.OnMultiChoiceClickListener() { 
     int count = 0; 
     @Override 
     public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
      if(isChecked) { 
       if (!selectedgenre.contains(String.valueOf(array[which]))) 
        if(selectedgenre.size()<5) 
       { 
        selectedgenre.add(String.valueOf(array[which])); 
        checkedGenres[which]=true;      
       } 
       else{ 
         count--; 
         ((AlertDialog) dialog).getListView().setItemChecked(which, false); 
         checkedGenres[which]=false; 
         Toast.makeText(getApplicationContext(),"you can't add this genre",Toast.LENGTH_LONG).show(); 
        } 
      } 
      else if (selectedgenre.contains(String.valueOf(array[which]))) 
      { 
       selectedgenre.remove(String.valueOf(array[which])); 
       checkedGenres[which]=false; 
      } 
     } 
    }

builder.setMultiChoiceItems(array, checkedGenres, new DialogInterface.OnMultiChoiceClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
       if(isChecked) { 
        if (!selectedgenre.contains(String.valueOf(which))) 
         if(selectedgenre.size()<5) 
        { 
         selectedgenre.add(String.valueOf(which)); 
         checkedGenres[which]=true; 
        } 
        else{ 
         //set your checkbox to false here 
         //yourCheckbox.setchecked(false); 
          Toast.makeText(getApplicationContext(),"you can't add more genres",Toast.LENGTH_LONG).show(); 
         } 
       } 
       else 
       { 
       selectedgenre.remove(String.valueOf(which)); 
       checkedGenres[which]=false; 
      } 
     } 
    } 

這一嘗試..問題在你的其他部分

在您的其他部分，在您的複選框上放置可點擊的false，並更改顏色以便用戶識別它。
