Android的 - startActivityForResult获取文件的路径 [英] Android - startActivityForResult for getting file's path

问题描述

我为Android编写一个简单的图像浏览器。我的应用程序有按钮，在从库打开文件。所以，当我从选用画廊的形象，它必须返回到文件到我的应用程序的路径，但它返回一个奇怪的Uri，它看起来像内容：//媒体/存储/ 2CH / 30128 。

I'm writing a simple image viewer for Android. My app have the "Open file from Gallery" button. So, when I've choosed the image from Gallery, it must return the path to file into my app, but it return a strange Uri, which looks like content://media/storage/2ch/30128.

我如何得到这个开放的绝对路径？
下面是一些code发动画廊：

How I can get an absolute file path from this Uri? Here's some code for launching Gallery:

    Intent i = new Intent();
    i.setType("image/*");
    i.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(i, "Выберите файл"), PICTURE_REQUEST_CODE);

推荐答案

使用此code

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  

   super.onActivityResult(requestCode, resultCode, data); 
   if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data){

      Uri selectedImage = data.getData();
      String[] filePathColumn = { MediaStore.Images.Media.DATA };
      Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
      cursor.moveToFirst();
      int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
      String picturePath = cursor.getString(columnIndex);
      cursor.close();
}
