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)

直接上代买吧：
