上面这个是核心的工具类，就是打开各种文档的跳转写法，然后在对应的点击事件调用 就可以，举列
protected void openFile(String path) {
String format = path.substring(path.lastIndexOf(".") + 1);
File file = new File(path);
try {
if (file.exists() || FileUtil.fileAvailable(file)) {
if (TextUtils.equals(“doc”, format) || TextUtils.equals(“docx”, format)) {
mContext.startActivity(IntentDocumentView.getWordFileIntent(path));
} else if (TextUtils.equals(“xls”, format) || TextUtils.equals(“xlsx”, format)) {
mContext.startActivity(IntentDocumentView.getExcelFileIntent(path));
} else if (TextUtils.equals(“zip”, format) || TextUtils.equals(“rar”, format)) {
mContext.startActivity(IntentDocumentView.getZipRarFileIntent(path));
}else if (TextUtils.equals(“pdf”, format) || TextUtils.equals(“PDF”, format)) {
mContext.startActivity(IntentDocumentView.getPdfFileIntent(path));
}else {
ToastUtil.showToast(mContext, “新增文件类型，请联系软件开发商”);
}
} else {
ToastUtil.showToast(mContext, “请先下载文件”);
}
} catch (Exception e) {
e.printStackTrace();
ToastUtil.showToast(mContext, “请先安装可以查看” + format + “格式的软件”);
}
ToastUtil.showToast(mContext, “请先下载文件”);
}
} catch (Exception e) {
e.printStackTrace();
