最近做了安卓仿微信上传图片，果断把大神的demo拷了过来，后来发现上传的时候出现了几个问题，那个博客下老是提醒链接过多，评论不了，就搬到这了##

---------首先先贴大神的demo地址：http://blog.csdn.net/jdsjlzx/article/details/44160603#html

获取的图片就是null，尤其是拍照的，我就把那个FileUtil那个存储bitmap的方法给返回了一个路径，然后就好了，下面是照相机返回的路径

//照相机
public void photo() {
    Intent openCameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(openCameraIntent, TAKE_PICTURE);
}


//照相机返回的图片
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
    switch (requestCode) {
        case TAKE_PICTURE:
            if (Bimp.tempSelectBitmap.size() < 9 && resultCode == RESULT_OK) {
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        String fileName = String.valueOf(System.currentTimeMillis() + ".png");
                        Bitmap bm = (Bitmap) data.getExtras().get("data");
                        String path = FileUtils.saveBitmap(bm, fileName);
                        ImageItem takePhoto = new ImageItem();
                        takePhoto.setBitmap(bm);
                        takePhoto.setImagePath(path);
                        Bimp.tempSelectBitmap.add(takePhoto);
                    }
                }).start();
            }
            break;
    }
}

--------Fileutil中return SDPATH + picName;就可以了，办法有点笨，但是不出错

2.在GridAdapter中的update()方法中，要么给loading()中的else后面添加break；要么改成adapter.notifyDataSetChanged();
之后就不会出现oom，并且导致时不时点不了的情况了

 //所选图片适配
    @SuppressLint("HandlerLeak")
    public class GridAdapter extends BaseAdapter {
        private LayoutInflater inflater;
        private int selectedPosition = -1;
        private boolean shape;

        public boolean isShape() {
            return shape;
        }

        public void setShape(boolean shape) {
            this.shape = shape;
        }

        public GridAdapter(Context context) {
            inflater = LayoutInflater.from(context);
        }

        public void update() {
            // loading();
            adapter.notifyDataSetChanged();
        }

        public int getCount() {
            if (Bimp.tempSelectBitmap.size() == 9) {//最多选9张图片
                return 9;
            }
            return (Bimp.tempSelectBitmap.size() + 1);
        }

        public Object getItem(int arg0) {
            return null;
        }

        public long getItemId(int arg0) {
            return 0;
        }

        public void setSelectedPosition(int position) {
            selectedPosition = position;
        }

        public int getSelectedPosition() {
            return selectedPosition;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder;
            if (convertView == null) {
                convertView = inflater.inflate(R.layout.item_upload_gridview,
                        parent, false);
                holder = new ViewHolder();
                holder.image = (ImageView) convertView
                        .findViewById(R.id.item_grida_image);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }
            if (Bimp.tempSelectBitmap != null) {
                if (position == Bimp.tempSelectBitmap.size()) {
                    holder.image.setImageBitmap(BitmapFactory.decodeResource(
                            getResources(), R.mipmap.ic_add_img));//加号

                    if (position == 9) {//只能选9张图片
                        holder.image.setVisibility(View.GONE);
                    }
                } else {
                    holder.image.setImageBitmap(Bimp.tempSelectBitmap.get(position).getBitmap());
                    imagePath = Bimp.tempSelectBitmap.get(position).getImagePath();//这是相册选中的图片路径，大神有说的
                    map.put(position, imagePath);
                    System.out.println("list选中上传的集合---" + map.size());
                    System.out.println("list选中上传的集合Path---" + map.get(position));

                }
            }
            return convertView;
        }

        public class ViewHolder {
            public ImageView image;
        }

        Handler handler = new Handler() {
            public void handleMessage(Message msg) {
                switch (msg.what) {
                    case 1:
                        adapter.notifyDataSetChanged();
                        break;
                }
                super.handleMessage(msg);
            }
        };

        //添加break，就可以调用
        public void loading() {
            new Thread(new Runnable() {
                public void run() {
                    while (true) {
                        if (Bimp.max == Bimp.tempSelectBitmap.size()) {
                            Message message = new Message();
                            message.what = 1;
                            handler.sendMessage(message);
                            break;
                        } else {
                            Bimp.max += 1;
                            Message message = new Message();
                            message.what = 1;
                            handler.sendMessage(message);
                            break;//在这添加
                        }
                    }
