为什么系统的其他软件打开相应的文件呢?
好!!!!!我来先举起"栗子"
文件管理器我就不说了显得很lOW
有些APP在某些服务上会附带相应的PDF文档,难道就为了一个PDF文档你要编写一个PDF查看器吗?就算你有大把的时间难道你能写的比那些专业级别的还要好?
在网络上混了这么久,有句话说的好, No picture you say a jb?
成功举起一个栗子
废话有点多直接贴代码
File file = new File(mQuickAdapter.getItem(position).getPath());
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "text/plain");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}else{
Toast.makeText(getContext(), "文件不存在或已被删除", Toast.LENGTH_SHORT).show();
}
当然写这篇文字为的可不是这两句代码:重点在"txt/plain" 以下是相应文件扩展名对应的类型
