如何使用复选框列表视图上工作了MultipleChoice过滤器 [英] How to work out MultipleChoice filters on Listview using checkbox

问题描述

我有不同类别的像ID，姓名，性别，地域，种姓，宗教的过滤器。现在，我想使用多重选择器显示复选框，我怎么能制定出具有多种选择的过滤器，因为有很多类型的过滤器，这样置换和放大器;组合是最差的。
目前，我带过滤器的单一选择（1复选框真正在同一时间）完成的。

解决方案

 字符串str [] =新的String [（'Z' - 'A'）+ 1];
布尔selectedItems [] =新的布尔[str.length]
保护的ArrayList＆LT;＆CharSequence的GT; selectedChars =新的ArrayList＆LT;＆CharSequence的GT;（）;
私人AlertDialog alertBox;私人无效showSpinner（）{    AlertDialog.Builder alertBuilder =新AlertDialog.Builder（本）;    INT A = 0;
    对于（字符C ='A'; C＆LT;'Z'; C ++）{
        STR [A +] =将String.valueOf（C）;
    }
    布尔[] = checkedChars新的布尔[str.length]
    诠释计数= str.length;
    的for（int i = 0; I＆LT;计数;我++）
        checkedChars [I] = selectedChars.contains（STR [I]）;    alertBuilder.setTitle（选择国家）;
    alertBuilder.setCancelable（真）;
    alertBuilder.setMultiChoiceItems（STR，selectedItems，
            新OnMultiChoiceClickListener（）{                @覆盖
                公共无效的onClick（DialogInterface对话，诠释它，
                        布尔器isChecked）{
                    如果（器isChecked）
                        selectedChars.add（STR [它]）;
                    其他
                        selectedChars.remove（STR [它]）;
                }
            }）;    alertBox = alertBuilder.create（）;
    alertBox.show（）;
}
 

将JST显示与多张的选择选项微调。

I have different categories of filters like id, name, gender, area, caste, religion. Now i want to use multiple choice filters showing checkboxes, how can i work out with multiple choice filters because there are many kind of filters so permutation & combination is worst for it. currently i am done with single selection of filter (1 checkbox true at a time).

解决方案

String str[] = new String[('Z' - 'A') + 1];
boolean selectedItems[] = new boolean[str.length];
protected ArrayList<CharSequence> selectedChars = new ArrayList<CharSequence>();
private AlertDialog alertBox;

private void showSpinner() {

    AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);

    int a = 0;
    for (char c = 'A'; c < 'Z'; c++) {
        str[a++] = String.valueOf(c);
    }
    boolean[] checkedChars = new boolean[str.length];
    int count = str.length;
    for (int i = 0; i < count; i++)
        checkedChars[i] = selectedChars.contains(str[i]);

    alertBuilder.setTitle("Select Country");
    alertBuilder.setCancelable(true);
    alertBuilder.setMultiChoiceItems(str, selectedItems,
            new OnMultiChoiceClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which,
                        boolean isChecked) {
                    if (isChecked)
                        selectedChars.add(str[which]);
                    else
                        selectedChars.remove(str[which]);
                }
            });

    alertBox = alertBuilder.create();
    alertBox.show();
}

it will jst display the spinner with mulitple selection options.
