[移动开发]android 11如何剪裁上传图片

1、剪裁代码

 /**
     * 图片裁剪，裁剪后存放在沙盒目录下(沙盒目录/picture/子文件夹)
     *
     * @param activity activity
     * @param uri      图片uri
     * @return 裁剪后的图片uri
     */
    public static void openCrop(Activity activity, Uri uri) {
        if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
            //未挂在存储设备或者没有读写权限
            return;
        }
        imgName = System.currentTimeMillis() + ".jpg";
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        intent.setDataAndType(uri, "image/*");
        // 设置裁剪
        intent.putExtra("crop", "true");
        // aspectX aspectY 是宽高的比例
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);

//        intent.putExtra(MediaStore.EXTRA_OUTPUT, resultUri);
        // 图片格式
        intent.putExtra("outputFormat", "png");
        intent.putExtra("noFaceDetection", true);// 取消人脸识别
        intent.putExtra("return-data", true);// true:不返回uri，false：返回uri
        if (Build.VERSION.SDK_INT >= 30) {
            //android 11以上，将文件创建在公有目录
            String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath();
            //storage/emulated/0/Pictures
            File mOnputFile = new File(path, imgName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.parse("file://" + mOnputFile.getAbsolutePath()));
        }
        activity.startActivityForResult(intent, REQUEST_CODE_CAPTURE_CROP);
    }

2、上传代码

  /**
     * @param bmpPath
     */
    public static void uploadImg(Activity activity, String bmpPath, String name) {
        Log.d(TAG, "uploadImg utils: " + bmpPath + "," + name);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
            file = new File(Environment.getExternalStoragePublicDirectory(DIRECTORY_PICTURES) + File.separator + name);
            Log.d(TAG, "uploadImg file: " + file.getAbsolutePath());
            FileUtils.uploadHeadImage(activity, file, Constant.HEAD_URL);
        } 
    }

具体上传逻辑根据自己需要编写。

其中file = new File(Environment.getExternalStoragePublicDirectory(DIRECTORY_PICTURES) + File.separator + name);很重要
