android 调用系统图片浏览器并返回图片路径

调用系统图片浏览器的方法如下：

Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, IMAGE_SELECT);

 activitity回调方法如：

protected void onActivityResult(int requestCode, int resultCode, Intent data)
	{
		if (resultCode == Activity.RESULT_OK)
		{
			Uri uri = data.getData();
			Cursor cursor = this.getContentResolver().query(uri, null, null, null, null);
			cursor.moveToFirst();
			for (int i = 0; i < cursor.getColumnCount(); i++)
			{// 取得图片uri的列名和此列的详细信息
				System.out.println(i + "-" + cursor.getColumnName(i) + "-" + cursor.getString(i));
			}
		}
	}
