Android 由图片资源ID获取图片的文件名

@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (resultCode == RESULT_OK) {
   Uri uri = data.getData();
   Cursor cursor = getContentResolver().query(uri, null, null, null,
     null);
   cursor.moveToFirst();
   String imgNo = cursor.getString(0); // 图片编号
   String imgPath = cursor.getString(1); // 图片文件路径
   String imgSize = cursor.getString(2); // 图片大小
   String imgName = cursor.getString(3); // 图片文件名
   // Log.e("uri", uri.toString());
   ContentResolver cr = this.getContentResolver();
   try {
    Bitmap bitmap = BitmapFactory.decodeStream(cr
      .openInputStream(uri));
    ImageView imageView = (ImageView) findViewById(R.id.imview);
    /* 将Bitmap设定到ImageView */
    imageView.setImageBitmap(bitmap);
   } catch (FileNotFoundException e) {
    // Log.e("Exception", e.getMessage(),e);
   }
  }
  super.onActivityResult(requestCode, resultCode, data);
 }
