解决: android11 系统裁剪图片

FileProvider.getUriForFile 请自行查阅资料

    public void startPhotoZoom(Uri uri){
        if(uri == null)
        {
            finish();
            return;
        }
        String name = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()) +"cut.jpg";
        File CropPhoto = new File(getExternalCacheDir(), name);
        //m_ResultImagePath = CropPhoto.getPath();
        mPhotoUri = Uri.fromFile(CropPhoto);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)
        {
            CropPhoto = uriToFileApiQ(uri, context);
            mPhotoUri = FileProvider.getUriForFile(context,
                    getPackageName() + ".fileprovider", CropPhoto);
        }
        headPath = CropPhoto.getPath();

        Intent intent = new Intent("com.android.camera.action.CROP");
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q)
        {
            intent.setDataAndType(mPhotoUri, "image/*");
        }
        else
        {
            intent.setDataAndType(uri, "image/*");
        }

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION ); //添加这一句表示对目标应用临时授权该Uri所代表的文件
        }
        intent.putExtra("crop", "true");
        intent.putExtra("scale", true);
        if(Build.MANUFACTURER.equals("HUAWEI")) {
            intent.putExtra("aspectX", 9998);
            intent.putExtra("aspectY", 9999);
        }
        else {
            intent.putExtra("aspectX", 1);
            intent.putExtra("aspectY", 1);
        }

        intent.putExtra("outputX", headWidth);
        intent.putExtra("outputY", headHight);
        intent.putExtra("return-data", false);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
        intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
        //intent.putExtra("noFaceDetection", true); // no face detection

        try {
            startActivityForResult(intent, RESULT_REQUEST_CODE);//这里的RESULT_REQUEST_CODE是在startActivityForResult里使用的返回值。
        } catch (Exception e) {
            // 解决截取后部分机型秒退
            e.printStackTrace();
        }
    }

uriToFileApiQ函数:

    @TargetApi(Build.VERSION_CODES.Q)
    public static File uriToFileApiQ(Uri uri, Context context) {
        File file = null;
        if(uri == null) return file;
        //android10以上转换
        if (uri.getScheme().equals(ContentResolver.SCHEME_FILE)) {
            file = new File(uri.getPath());
        } else if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
            //把文件复制到沙盒目录
            ContentResolver contentResolver = context.getContentResolver();
            String displayName = System.currentTimeMillis()+ Math.round((Math.random() + 1) * 1000)
                    +"."+ MimeTypeMap.getSingleton().getExtensionFromMimeType(contentResolver.getType(uri));

//            注释掉的方法可以获取到原文件的文件名，但是比较耗时
//            Cursor cursor = contentResolver.query(uri, null, null, null, null);
//            if (cursor.moveToFirst()) {
//                String displayName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));}

            try {
                InputStream is = contentResolver.openInputStream(uri);
                File cache = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES).getAbsolutePath(), displayName);
                FileOutputStream fos = new FileOutputStream(cache);
                FileUtils.copy(is, fos);
                file = cache;
                fos.close();
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return file;
    }
