1、进入本地文件（添加文件）：

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);

//显示文件管理器列表
try {
startActivityForResult(Intent.createChooser(intent, "请选择一个要上传的文件"),FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(ProposalActivity.this, "请安装文件管理器", Toast.LENGTH_SHORT).show();
}

查看不同类型文件：

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(“文件路径”);
if(“文件类型”.equals("pdf")){
//使用指定工具打开，参数为工具包名和打开页面的Activity。无改代码时，弹出可打开该文件的工具列表。

intent.setClassName("com.ebensz.pdf", "com.ebensz.pdf.pdfsign.droid.PdfViewerActivity");
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
}else{
Toast.makeText(FileGridActivity.this, "不支持该文件！", Toast.LENGTH_SHORT).show();
return;
}
startActivity(intent);

文件对应类型列表：

  //{后缀名，MIME类型}
            {".3gp",    "video/3gpp"},
            {".apk",    "application/vnd.android.package-archive"},
