Android(安卓)实现头像上传功能

之前做这个功能还是花了好多时间的今天我将我的代码分享给大家先看效果图

首先看上传图片的工具类，一点都没有少复制就可以用

从相册获取图片的方法

/** * 从相册选择图片来源 */private void getPhoto() {    Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);    intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,            "image/*");    startActivityForResult(intent, PHOTO_REQUEST);}

从系统相机拍照获取照片

/** * 从系统相机选择图片来源 */private void getCamera() {    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);    // 下面这句指定调用相机拍照后的照片存储的路径    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(            Environment.getExternalStorageDirectory(), "hand.jpg")));    startActivityForResult(intent, CAMERA_REQUEST);}

调用系统裁剪工具裁剪图片

/**** * 调用系统自带切图工具对图片进行裁剪 * 微信也是 * * @param uri */private void photoClip(Uri uri) {    // 调用系统中自带的图片剪裁    Intent intent = new Intent("com.android.camera.action.CROP");    intent.setDataAndType(uri, "image/*");    // 下面这个crop=true是设置在开启的Intent中设置显示的VIEW可裁剪    intent.putExtra("crop", "true");    // aspectX aspectY 是宽高的比例    intent.putExtra("aspectX", 1);    intent.putExtra("aspectY", 1);    // outputX outputY 是裁剪图片宽高    intent.putExtra("outputX", 150);    intent.putExtra("outputY", 150);    intent.putExtra("return-data", true);    startActivityForResult(intent, PHOTO_CLIP);}

上传服务器的方法

/** * 上传图片到服务器 */private void toUploadFile() {    pd = ProgressDialog.show(this, "", "正在上传文件...");    pd.show();    String fileKey = "avatarFile";    UploadUtil uploadUtil = UploadUtil.getInstance();    uploadUtil.setOnUploadProcessListener(MainActivity.this); //设置监听器监听上传状态    Map, String> params = new HashMap, String>();//上传map对象    params.put("userId", "");    uploadUtil.uploadFile(filepath, fileKey, "上传头像的地址", params);    Toast.makeText(this, "上传成功", Toast.LENGTH_LONG).show();}

重新服务器响应方法

/** * 上传服务器响应回调 */@Overridepublic void onUploadDone(int responseCode, String message) {    //上传完成响应    pd.dismiss();    Message msg = Message.obtain();    msg.what = UPLOAD_FILE_DONE;    msg.arg1 = responseCode;    msg.obj = message;}@Overridepublic void onUploadProcess(int uploadSize) {    //上传中    Message msg = Message.obtain();    msg.what = UPLOAD_IN_PROCESS;    msg.arg1 = uploadSize;}@Overridepublic void initUpload(int fileSize) {    //准备上传    Message msg = Message.obtain();    msg.what = UPLOAD_INIT_PROCESS;    msg.arg1 = fileSize;}

重写这些方法需要实现接口

public class MainActivity extends AppCompatActivity implements View.OnClickListener, UploadUtil.OnUploadProcessListener {

重写onActivityResult获取数据

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    switch (requestCode) {        case CAMERA_REQUEST:            switch (resultCode) {                case -1://-1表示拍照成功                    File file = new File(Environment.getExternalStorageDirectory()                            + "/hand.jpg");//保存图片                    if (file.exists()) {                        //对相机拍照照片进行裁剪                        photoClip(Uri.fromFile(file));                    }            }            break;        case PHOTO_REQUEST://从相册取            if (data != null) {                Uri uri = data.getData();                //对相册取出照片进行裁剪                photoClip(uri);            }            break;        case PHOTO_CLIP:            //完成            if (data != null) {                Bundle extras = data.getExtras();                if (extras != null) {                    Bitmap photo = extras.getParcelable("data");                    try {                        //获得图片路径                        filepath = UploadUtil.saveFile(photo, Environment.getExternalStorageDirectory().toString(), "hand.jpg");                        //上传照片                        toUploadFile();                    } catch (IOException e) {                        e.printStackTrace();                    }                    //上传完成将照片写入imageview与用户进行交互                    mImageView.setImageBitmap(photo);                }            }            break;    }}
