2010.12.28(3)——— android alertDialog 复选框问题

需求：要一个有复选框的alertDialog，并且数据一个bean的list集合

思路：刚开始想既然是list集合就用Adapter吧，但是在alertDialog.builder的set方法里面只有setAdapter和setSingleChoiceItems的参数是ListAdapter，但是无法有复选框当然用setAdapter是可以构建复选框的但是需要一个layout的xml文件很麻烦
而alertDialog.builder的setMultiChoiceItems只能传一个字符串数组所以我就选择了把list拆开组成一个数组

代码：

String json = QueryService.queryRgncdGcxz();String[] str = json.split(";");String str_rgncd = str[0];List<GC_RGNCD>  list_rgncd = JSONUtil.parseJSON_GCRGNCD(str_rgncd);String[] arrs = new String[list_rgncd.size()];boolean[] boos = new boolean[list_rgncd.size()];final List<Integer> checks = new ArrayList<Integer>();for(int i=0;i<list_rgncd.size();i++){GC_RGNCD bean = list_rgncd.get(i);arrs[i] = bean.getRGNNM();boos[i] = false;}new AlertDialog.Builder(XZJL_UploadActivity.this).setTitle("请选择: ").setMultiChoiceItems(arrs, boos, new OnMultiChoiceClickListener(){public void onClick(DialogInterface dialog, int which,boolean isChecked) {// TODO Auto-generated method stubif(isChecked){checks.add(which);}else{checks.remove(which);}}}).setPositiveButton("发送", new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface dialog, int whichButton) {                    SmsManager manager = SmsManager.getDefault();ArrayList<String> texts = manager.divideMessage("重大安全事故，请领导查看");String[] mobiles = {"15311222","152104642","13084566"};for(Integer in : checks){String mobile = mobiles[in];for(String text : texts){manager.sendTextMessage(mobile, null, text, null, null);}}Toast.makeText(XZJL_UploadActivity.this, "上报成功", 0).show();Intent intent = new Intent(XZJL_UploadActivity.this,MainActivity.class);startActivity(intent);                    }                })                .setNegativeButton("取消", new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface dialog, int whichButton) {                        /* User clicked No so do some stuff */                    }                })                .create().show();

就是一个群发短信的例子
