死循环？？？？？？？？

Question

List<Integer> drawableList=new ArrayList<Integer>();
       
       public List<Integer> getDrawableList(){
        drawableList.add(R.drawable.emo_im_cool);
        drawableList.add(R.drawable.emo_im_crying);
        drawableList.add(R.drawable.emo_im_first);
        drawableList.add(R.drawable.emo_im_happy);
        drawableList.add(R.drawable.emo_im_kissing);
        drawableList.add(R.drawable.emo_im_laughing);
        drawableList.add(R.drawable.emo_im_lips_are_sealed);
        drawableList.add(R.drawable.emo_im_money_mouth);
        drawableList.add(R.drawable.emo_im_sad);
        drawableList.add(R.drawable.emo_im_tongue_sticking_out);
        drawableList.add(R.drawable.emo_im_undecided);
        drawableList.add(R.drawable.emo_im_winking);
        drawableList.add(R.drawable.emo_im_wtf);
        drawableList.add(R.drawable.emo_im_yelling);  
       return drawableList;
       }for(int i=0;i<d.getDrawableList().size();i++){
         Log.d(TAG, "123");
         //break;
//         values.put("STU_PHOTO",d.getDrawableList().get(i) );
//         values.put("STU_NAME", "WangChen");
//         values.put("STU_TITLE", "TB0904060");
//         getContentResolver().insert(uri, values);
        }
我用list数组大小作为循环的条件,这个是死循环吗?...我去.......

Answer 1

d.getDrawableList().size()   //d是神马情况？for(int i=0;i<getDrawableList().size();i++){
  Log.d(TAG, "123");

Answer 2

测试用的。看看打印了几次。这句无关紧要的啊。就相当于main函数里的额System.out.print("123")

Answer 3

for(int i=0;i<getDrawableList().size();i++)一般数组的长度是用.length吧
你调试看看.size()是不是获得的是与你图片大小相关的数

Answer 4

for(int i=0;i<d.getDrawableList().size();i++){
d 是哪来的??

Answer 5

d是    实例化的那个类的一个变量。用不了lentha啊/晕

Answer 6

d.getDrawableList() 的返回类型是List<Integer>，
当然只能用size()了，试着在循环前打出d.getDrawableList().size()的大小
就知道是什么原因了

Answer 7

确实是死循环，for(int i=0;i<getDrawableList().size();i++),循环时每次getDrawableList()，你都往drawableList加数据
public List<Integer> getDrawableList(){  drawableList.clear();  //.......  drawableList.add(R.drawable.emo_im_cool);
  drawableList.add(R.drawable.emo_im_crying);
  drawableList.add(R.drawable.emo_im_first);
  drawableList.add(R.drawable.emo_im_happy);
  drawableList.add(R.drawable.emo_im_kissing);
  drawableList.add(R.drawable.emo_im_laughing);
  drawableList.add(R.drawable.emo_im_lips_are_sealed);
  drawableList.add(R.drawable.emo_im_money_mouth);
  drawableList.add(R.drawable.emo_im_sad);
  drawableList.add(R.drawable.emo_im_tongue_sticking_out);
  drawableList.add(R.drawable.emo_im_undecided);
  drawableList.add(R.drawable.emo_im_winking);
  drawableList.add(R.drawable.emo_im_wtf);
  drawableList.add(R.drawable.emo_im_yelling);   
  return drawableList;
  }

Answer 8

呵呵 我2了 8楼正解 调试一下是不是size每次都会变大~~

Answer 9

死的好惨以后别这样用size了，你这还好是加的，要是减的你会丢数据，到时候就是一个隐藏的大bug
