現在的專案要增加一個使用者反饋功能，由於是臨時提出的需求也沒有UI設計，就想到參照微信的設計來實現。
先看微信的效果：

在web端實現的，開始也想過做在web端這樣更靈活，但目前的架構還是傳統的純native應用，這麼搞太麻煩，估計要搗鼓一段時間，還是就用android端實現。

功能分析

使用者點選新增圖片按鈕後在手機圖片庫中選擇照片，選定後展示出來，最多選擇4張，水平排列，一行不夠排兩行，就想到GridView結合startActivityForResult+ 執行緒池來實現。因為是上傳圖片，最好轉變為webp格式，再加上畫素壓縮處理，可以大大的節省使用者流量。

流程：
輸入文字->startActivityForResult選擇照片->onActivityResult中更新GridView->點選提交->彈出等待提示框->建立檔案List，文字儲存為txt格式，從GridView中取出圖片儲存為webp格式->執行緒池上傳檔案->上傳結束關閉等待提示框。

功能實現

想起來簡單做起來的時候才發現很多問題，上傳圖片時想彈出一個含旋轉動畫的等待提示框（繼承DialogFragment），每個執行緒執行完後得到執行結果，根據結果設定等待提示框的文字，採用ExecutorService.submit() + future.get()實現時發現一個奇怪的現象：從點選提交到上傳結束沒有看到等待提示框，後來一步步排查問題發現，ExecutorService.submit()之後就會進入future.get()，get()方法會阻塞UI執行緒，導致無法彈出提示框；當執行緒池結束才回到UI執行緒，此時會先處理之前的任務（彈出等待提示框），但由於執行緒池結束又呼叫了DialogFragment的dissmiss()方法，等待提示框很快出現又很快消失了。
好吧，由於沒有搞懂執行緒池浪費了大把時間，程式碼也白寫了，但也讓我對執行緒池加深了認識，這一特性大概幾年都不會忘了，於是又重新考慮實現方式。

最終的實現方式是自定義一個執行緒池，用一個迴圈執行Runnable。
自定義執行緒池：

    class MyThreadPool extends ThreadPoolExecutor {

        private List<File> fileList;
        private MyThreadPool(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit,
                             BlockingQueue<Runnable> workQueue, List<File> files) {
            super
 
(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue);
            fileList = files;
        }

        @Override
        protected void beforeExecute(Thread t, Runnable r) {
            super.beforeExecute(t, r);
        }

        @Override
        protected void afterExecute(Runnable r, Throwable t) {
            super.afterExecute(r, t);
        }

        @Override
        protected void terminated() {
            super.terminated();
            //當呼叫shutDown()或者shutDownNow()時會觸發該方法，關掉等待框
            waitingDialog.dismissAllowingStateLoss();

            for (File file:fileList){
                deleteOldLogcatFile(getApplicationContext(), file.getName());
            }

            //必須用looper才能線上程中用toast
            Looper.prepare();
            if (uploadSucc){
                Toast.makeText(getApplicationContext(), "上傳完成", Toast.LENGTH_LONG).show();
            } else{
                Toast.makeText(getApplicationContext(), "上傳失敗！", Toast.LENGTH_LONG).show();
            }
            Looper.loop();
        }
    }

自定義的好處是線上程池結束後可以自定義提示資訊，在terminated()中刪除了舊檔案，並根據每個執行緒結果提示上傳成功還是失敗。
呼叫自定義執行緒

MyThreadPool myThreadPool = new MyThreadPool(2, 4, 1,
                TimeUnit.MINUTES, new ArrayBlockingQueue<Runnable>(fileCount), files);
        for (int i = 0; i < fileCount; i++) {
            final File file = files.get(i);
            Runnable runnable = new Runnable(){
                @Override
                public void run() {
                    int ret = ftpUpload(ftpUrl, fptPort, ftpUserName, ftpPassword, ftpRemotePath, path, file.getName());
                    ECMLog.i_ui(CLASS_TAG, "ftpUpload ret: " + ret);
                    uploadSucc = ret == FTP_UPLOAD_SUCC;
                }
            };
            myThreadPool.execute(runnable);
        }

        myThreadPool.shutdown();

還有個效果是點選選擇好的圖片後放大顯示圖片，圖片下方有個刪除圖示能刪除圖片，這也是通過startActivityForResult實現，在onActivityResult中刪除GridView中對應圖片。

圖片處理

startActivityForResult要用兩次，一次是新增圖片，一次是點選已新增的圖片然後重新啟動一個activity顯示圖片，在這個activity中能刪除已選擇的圖片。

圖片的壓縮處理：onActivityResult拿到圖片uri，根據uri得到路徑，通過路徑加上畫素壓縮演算法得到bitmap，再呼叫bitmap.compress()得到webp格式的圖片檔案。

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK && requestCode == REQUEST_ADD_PIC) {
            Uri uri = data.getData();

            String picPath = Utils.getFilePathFromUri(getApplicationContext(), uri);
            if (picPath == null){
                ContentResolver cr = this.getContentResolver();
                try {
                    mBitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            }else {
                mBitmap = Utils.getSmallBitmap(picPath, 480, 800);
            }

            //加到第一個
            mGridViewUris.add(0, uri);
            mGridViewDatas.add(0, mBitmap);

            mGridViewAdapter=new GridViewAdapter(getApplication(), mGridViewDatas, MAX_UPLOAD_PIC);
            mGridView.setAdapter(mGridViewAdapter);
            mGridViewAdapter.notifyDataSetChanged();

        }else if (resultCode == RESULT_OK && requestCode == REQUEST_SHOW_PIC){
            int position = data.getIntExtra(PIC_POSITION, 0);
            mGridViewDatas.remove(position);
            mGridViewUris.remove(position);
            mGridViewAdapter=new GridViewAdapter(getApplication(), mGridViewDatas, MAX_UPLOAD_PIC);
            mGridView.setAdapter(mGridViewAdapter);
            mGridViewAdapter.notifyDataSetChanged();
        }

        //包含新增圖片
        int totalPictures = mGridViewDatas.size();
        currentPicTV.setText(String.valueOf(totalPictures - 1));
    }

public static String getFilePathFromUri(final Context context, final Uri uri) {

                // Return the remote address
                if (isGooglePhotosUri(uri))
                    return uri.getLastPathSegment();

                return getDataColumn(context, uri, null, null);
            } else if ("file".equalsIgnoreCase(uri.getScheme())) {
                return uri.getPath();
            }
        }
        return null;
    }

//根據路徑獲得圖片並壓縮，返回bitmap用於顯示
    public static Bitmap getSmallBitmap(String filePath, int reqWidth, int reqHeight) {
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;

        final int width = options.outWidth;
        int inSampleSize = 1;
        if (height > reqHeight || width > reqWidth) {
            final int heightRatio = Math.round((float) height/ (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);
            inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
        }
        return inSampleSize;
    }

通過以上方式，一個截圖檔案原始大小300KB，被壓縮到10KB。
