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);
