android上传图片（相机，相册）

实现思路：
1.popWindow选择图片来自相机还是相册：

/**
     * 显示popWindow
     *
     */
    private void showPopWindow() {
        Log.i(TAG, "...showPop:");
        View popView = View.inflate(this.getActivity(), R.layout.popupwindow_camera_layout, null);
        Button fromLocalBtn = (Button) popView.findViewById(R.id.pop_fromlocal);
        Button fromCameraBtn = (Button) popView.findViewById(R.id.pop_fromcamera);
        Button cancelBtn = (Button) popView.findViewById(R.id.pop_cancel);

        //得到屏幕的宽高
        int width = getResources().getDisplayMetrics().widthPixels;
        int height = getResources().getDisplayMetrics().heightPixels * 1 / 3;
        final PopupWindow popupWindow = new PopupWindow(popView, width, height);
//        popupWindow.setAnimationStyle(R.style.anim_pop_dir);
        popupWindow.setFocusable(true);
        popupWindow.setOutsideTouchable(true);//点击外部pop消失
        WindowManager.LayoutParams lp = getActivity().getWindow().getAttributes();
        lp.alpha = 0.5f;
        getActivity().getWindow().setAttributes(lp);
        popupWindow.showAtLocation(popView, Gravity.BOTTOM, 0, 50);

        fromCameraBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                takeCamera(RESULT_CAMERA_IMAGE);
                popupWindow.dismiss();
            }
        });
        fromLocalBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, RESULT_LOCAL_IMAGE);
                popupWindow.dismiss();
            }
        });
        cancelBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                popupWindow.dismiss();
            }
        });

        //popupWindow消失屏幕变为不透明
        popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
            @Override
            public void onDismiss() {
                WindowManager.LayoutParams lp = getActivity().getWindow().getAttributes();
                lp.alpha = 1.0f;
                getActivity().getWindow().setAttributes(lp);
            }
        });

    }

贴一下布局文件吧，哎，虽然不屑于这样做。。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_margin="10dp"
        android:paddingBottom="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_alignParentBottom="true">

        <Button
            android:id="@+id/pop_fromcamera"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/fromCamera" />

        <Button
            android:id="@+id/pop_fromlocal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/fromLocal" />

        <Button
            android:layout_marginTop="10dp"
            android:id="@+id/pop_cancel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/cancel" />
    LinearLayout>
RelativeLayout>

2.打开相机：

/**
     * 打开相机拍照
     * @param resultCameraImage
     */
    private void takeCamera(int resultCameraImage) {
//        Intent takePicturIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        //确定第三方是否可以被打开
//        if (takePicturIntent.resolveActivity(getActivity().getPackageManager()) != null) {
//            File photoFile = null;
//            photoFile = createImageFile();
//            // Continue only if the File was successfully created
//            if (photoFile != null) {
//                takePicturIntent.putExtra(MediaStore.EXTRA_OUTPUT,
//                        Uri.fromFile(photoFile));
//            }
//        }
//        startActivityForResult(takePicturIntent, resultCameraImage);//跳转界面传回拍照所得数据

        if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
            File photoFile = null;
            photoFile = createImageFile();
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

//            Uri uri = getUriForFile(this.getActivity(), photoFile);
//            Log.i(TAG,"....uri:" + uri.toString());

            //这部分代码感觉就是鸡肋
//            ContentValues values = new ContentValues();
//            values.put(MediaStore.Images.Media.TITLE, photoFile.getName());
//            uri = getActivity().getContentResolver().insert(
//                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//            Log.i(TAG,"....uri:" + uri.toString());
//            intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);

            //测试发现，不加传递内容，onActivityResult中data才不为空，但是传递过去一个缩略图，要想获取原图，需要从保存图片的路径中拿
//            intent.putExtra(MediaStore.EXTRA_OUTPUT, getUriForFile(this.getActivity(), photoFile));
            intent.putExtra("imagePath", photoFile.getAbsoluteFile());
            startActivityForResult(intent, resultCameraImage);
        } else {
            Toast.makeText(getActivity(),"....",Toast.LENGTH_SHORT).show();
        }

    }

这么注释，就知道这个data有多纠结。不加传递内容，onActivityResult方法中data才不为空，但是data中的图片为缩略图，网上有同仁说跟手机机型有关系。
这里我加了传递参数，因为我把拍好的照片存起来了，在onActivityResult中从保存的路径中找这张图片，那必须就是原图了。

 private File createImageFile() {
        File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
        File image = null;
        try {
            image = File.createTempFile(
                    generateFileName(),  /* prefix */
                    ".jpg",         /* suffix */
                    storageDir      /* directory */
            );
        } catch (IOException e) {
            e.printStackTrace();
        }
        mCurrentPhotoPath = image.getAbsolutePath();
        Log.i(TAG,"....mCurrentPhotoPath" + mCurrentPhotoPath);
        return image;
    }

public static String generateFileName() {
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_" + timeStamp + "_";
        return imageFileName;
    }

拍好的图片就是在这个路径下的。

3.从相册选择：
主要就是这个意图：

 Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, RESULT_LOCAL_IMAGE);

4.onActivityResult方法接收数据的操作：

/**
     * 在onActivityResult方法中获取图片数据
     * @param requestCode
     * @param resultCode
     * @param data
     */
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.i(TAG,"....onActivityResult" + "...requestCode:" + requestCode + "...resultCode:" + resultCode + "...data:" + data);
        if (resultCode == RESULT_OK) {
            if (requestCode == RESULT_LOCAL_IMAGE && null != data) {
                Uri selectedImage = data.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getActivity().getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                final String picturePath = cursor.getString(columnIndex);//拿出了图片的路径
                Log.i(TAG,"...picturePath:" + picturePath);

                Map map = new HashMap();
                map.put("name", "lucas");
                ImageUpdateUtil.getInstance().uploadFile(picturePath, "file", UserContents.imageGetUrl, map);


                cursor.close();
            } else if (requestCode == RESULT_CAMERA_IMAGE ) {
                //你妹！data根本什么东东都没有好不好
//                String path = data.getStringExtra("imagePath");
//                Log.i(TAG,"...path:" + path);

//                Bundle extras = data.getExtras();
//                Bitmap b = (Bitmap) extras.get("data");
//                img.setImageBitmap(b);
//                String name = new SimpleDateFormat("yyyyMMddhhmmss").format(new Date());
//                String fileNmae = Environment.getExternalStorageDirectory().toString()+File.separator+"dong/image/"+name+".jpg";
//                String srcPath = fileNmae;
//                Log.i(TAG,"....srcPath:" + srcPath);
//                File myCaptureFile =new File(fileNmae);

                Map map = new HashMap();
                map.put("name", "lucas");
                ImageUpdateUtil.getInstance().uploadFile(mCurrentPhotoPath, "file", UserContents.imageGetUrl, map);



            }
        }

    }

5.来看上传的代码，我封装在ImageUpdateUtil这个类中，调用方式为：

Map<String, String> map = new HashMap<String, String>();
                map.put("name", "lucas");
                ImageUpdateUtil.getInstance().uploadFile(mCurrentPhotoPath, "file", UserContents.imageGetUrl, map)
