Android:在列表中显示对话框中的多个选择

// 创建一个列表对话框
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("选择项");
final String[] items = {"选项1", "选项2", "选项3", "选项4"};
final boolean[] checkedItems = {false, false, false, false};
builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
        checkedItems[which] = isChecked;
    }
});

// 处理用户的选择
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        StringBuilder selectedItems = new StringBuilder();
        for (int i = 0; i < items.length; i++) {
            if (checkedItems[i]) {
                selectedItems.append(items[i]).append(", ");
            }
        }
        // 处理选中的选项
        // ...
    }
});
builder.setNegativeButton("取消", null);

// 显示对话框
AlertDialog dialog = builder.create();
dialog.show();
