安卓上傳圓角頭像到服務(wù)器功能

第一次寫技術(shù)文章，有啥不對的地方往多多指教。
今天為大家?guī)硪黄蟼鲌A角頭像的功能吧。

功能邏輯流程

第一步 選擇照片/拍照(選擇照片和拍照分別需要文件讀取和相機(jī)權(quán)限)
第二步 剪切圓角
第三部 上傳圖片
這里我使用的是OkHttp（一款強(qiáng)大的網(wǎng)絡(luò)請求三方）來進(jìn)行網(wǎng)絡(luò)請求
GitHub地址

代碼如下：

    類屬性
    // 頁面返回參數(shù)
    private final int CHOOSE_PICTURE = 0;
    private final int TAKE_PICTURE = 1;
    private final int CROP_SMALL_PICTURE = 2;
    private final int MY_PERMISSIONS_REQUEST_CALL_PHONE = 6;
    // 圓角圖片地址
    private  Uri tempUri;

檢查權(quán)限

public void choosePhone(){
    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.WRITE_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    MY_PERMISSIONS_REQUEST_CALL_PHONE);

    }else {
        showChoosePicDialog();
    }
}

彈出選擇框

protected void showChoosePicDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("設(shè)置頭像");
        String[] items = { "選擇本地照片", "拍照" };
        builder.setNegativeButton("取消", null);
        builder.setItems(items, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                switch (which) {
                    case CHOOSE_PICTURE: // 選擇本地照片
                        // 判斷當(dāng)前系統(tǒng)版本
                        String intentactiong = "";
                        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {//4.4版本前
                            intentactiong = Intent.ACTION_GET_CONTENT;
                        } else {//4.4版本后
                            intentactiong = Intent.ACTION_PICK;
                        }
                        Intent openAlbumIntent = new Intent(intentactiong);
                        openAlbumIntent.setDataAndType(
                                MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
                        startActivityForResult(openAlbumIntent, CHOOSE_PICTURE);
                        break;
                    case TAKE_PICTURE: // 拍照
                        Intent openCameraIntent = new Intent(
                                MediaStore.ACTION_IMAGE_CAPTURE);
                        tempUri = Uri.fromFile(new File(Environment
                                .getExternalStorageDirectory(), "image.jpg"));
                        // 指定照片保存路徑（SD卡），image.jpg為一個(gè)臨時(shí)文件，每次拍照后這個(gè)圖片都會被替換
                        openCameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, tempUri);
                        startActivityForResult(openCameraIntent, TAKE_PICTURE);
                        break;
                }
            }
        });
        builder.create().show();
    }

裁剪圓角方法

protected void startPhotoZoom(Uri uri) {
        if (uri == null) {
            Log.i(TAG, "The uri is not exist.");
        }
        tempUri = uri;
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setDataAndType(uri, "image/*");
        // 設(shè)置裁剪
        intent.putExtra("crop", "true");
        // aspectX aspectY 是寬高的比例
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        // outputX outputY 是裁剪圖片寬高
        intent.putExtra("outputX", 150);
        intent.putExtra("outputY", 150);
        intent.putExtra("return-data", true);
        startActivityForResult(intent, CROP_SMALL_PICTURE);
        Log.d(TAG, "startPhotoZoom: 剪切完畢");
    }

保存裁剪之后的圖片數(shù)據(jù)

protected void setImageToView(Intent data) {
        Bundle extras = data.getExtras();
        if (extras != null) {
            Bitmap photo = extras.getParcelable("data");
            photo = ImgUtils.toRoundBitmap(photo, tempUri); // 這個(gè)時(shí)候的圖片已經(jīng)被處理成圓形的了
            avatar.setImageBitmap(photo);
            // 上傳頭像文件
            imgUriList.clear();
            String imagePath = ImgUtils.savePhoto(photo, Environment
                    .getExternalStorageDirectory().getAbsolutePath(), String
                    .valueOf(System.currentTimeMillis()));
            // 這里我是封裝的多文件上傳，所以使用list保存文件地址;
            imgUriList.add(imagePath);
        }
    }

重寫頁面返回值方法

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Log.d(TAG, "onActivityResult: resultCode=" + resultCode);
        if (resultCode == RESULT_OK) { // 如果返回碼是可以用的
            switch (requestCode) {
                case TAKE_PICTURE:
                    startPhotoZoom(tempUri); // 開始對圖片進(jìn)行裁剪處理
                    break;
                case CHOOSE_PICTURE:
                    startPhotoZoom(data.getData()); // 開始對圖片進(jìn)行裁剪處理
                    break;
                case CROP_SMALL_PICTURE:
                    if (data != null) {
                        setImageToView(data); // 讓剛才選擇裁剪得到的圖片顯示在界面上
                    }
                    break;
            }
        }
      
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)
    {

        if (requestCode == MY_PERMISSIONS_REQUEST_CALL_PHONE)
        {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                choosePhone();
            } else
            {
                // Permission Denied
                Toast.makeText(SettingAccounts.this, "Permission Denied", Toast.LENGTH_SHORT).show();
            }
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

好了，到了最后一步，也就是根據(jù)后臺給你的接口上傳圖片到你們服務(wù)器了

public void changeUserInfo() {
        // 檢查網(wǎng)絡(luò)狀態(tài)
        if (NetUtil.isNetworkAvalible(this)) {
    
            String address = "功能模塊地址";
            Map<String, Object> map = new HashMap<>();
            map.put("鍵", 值);
          
            try {
                HttpUtil.sendFileUpdataRequest(map, imgUriList, "pic", address, this, new HttpResponseInfo() {
                    @Override
                    public void responseOk() {
                    }

                    @Override
                    public void responseErr() {
                        runOnUiThread(new Runnable() {
                            @Override

                                loadingDialog.dismiss();
                                Toast.makeText(SettingAccounts.this, "修改失敗!", Toast.LENGTH_SHORT).show();
                            }
                        });
                    }

                    @Override
                    public void responseInfo(final String response) {
                        runOnUiThread(new Runnable() {

                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }
                 
                            }
                        });
                    }

                    @Override
                    public void requestErr() {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                    
                                Toast.makeText(SettingAccounts.this, "網(wǎng)絡(luò)請求失敗!", Toast.LENGTH_SHORT).show();
                            }
                        });
                    }
                });
            } catch (IOException e) {
                e.printStackTrace();
            }
        } else {
            NetUtil.checkNetwork(this);
        }
    }

網(wǎng)絡(luò)請求的方法(比較懶，就把多圖和單圖封裝了一個(gè)方法)，可根據(jù)自己后臺的需求改動
