androidQ(兼容) uri获取绝对路径和uri获取获取文件

//获取文件绝对路径

关于AndroidQ获取文件路径适配方案向下兼容
重要的事情说三遍
一定要有权限
一定要有权限
一定要有权限
这两个权限在AndroidQ上会默认转为AndroidQ所需要的权限，也可以用AndroidQ的新的权限（androidQ以下没有试过用androidQ的新权限）<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />//（需要拍照时使用）<uses-permission android:name="android.permission.CAMERA" />
  //获取拍照和选取的图片的绝对路径public static String getFilePathFromURI(Context context, Uri contentUri) {File rootDataDir = context.getExternalFilesDir(null);
//        MyApplication.getMyContext().getExternalFilesDir(null).getPath();String fileName = getFileName(contentUri);if (!TextUtils.isEmpty(fileName)) {File copyFile = new File(rootDataDir + File.separator + fileName);copyFile(context, contentUri, copyFile);return copyFile.getAbsolutePath();}return null;}public static String getFileName(Uri uri) {if (uri == null) return null;String fileName = null;String path = uri.getPath();int cut = path.lastIndexOf('/');if (cut != -1) {fileName = path.substring(cut + 1);}return fileName;}public static void copyFile(Context context, Uri srcUri, File dstFile) {try {InputStream inputStream = context.getContentResolver().openInputStream(srcUri);if (inputStream == null) return;OutputStream outputStream = new FileOutputStream(dstFile);copyStream(inputStream, outputStream);inputStream.close();outputStream.close();} catch (Exception e) {e.printStackTrace();}}public static int copyStream(InputStream input, OutputStream output) throws Exception, IOException {final int BUFFER_SIZE = 1024 * 2;byte[] buffer = new byte[BUFFER_SIZE];BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);int count = 0, n = 0;try {while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {out.write(buffer, 0, n);count += n;}out.flush();} finally {try {out.close();} catch (IOException e) {}try {in.close();} catch (IOException e) {}}return count;}

//uri获取绝对路径

String path=getFilePathFromURI(context,uri);

//uri获取文件(使用上面的方法)

File file = new File(getFilePathFromURI(context,uri));
