Android 打开PDF,PPT,WORD,EXCEL,CHM,HTML,TEXT,AUDIO,VIDEO 格式文件代码

importandroid.app.Activity;

importandroid.content.Intent;

importandroid.net.Uri;

importandroid.content.Intent;

//PDF,PPT,WORD,EXCEL,CHM,HTML,TEXT,AUDIO,VIDEO

示例:

//这个不行，可能是因为PDF.apk程序没有权限访问其它APK里的asset资源文件,又或者是路径写错?

//Intentit=getPdfFileIntent("file:///android_asset/helphelp.pdf");

//下面这些都OK

//Intentit=getHtmlFileIntent("/mnt/sdcard/tutorial.html");//SD卡主目录

//Intentit=getHtmlFileIntent("/sdcard/tutorial.html");//SD卡主目录,这样也可以

Intentit=getHtmlFileIntent("/system/etc/tutorial.html");//系统内部的etc目录

//Intentit=getPdfFileIntent("/system/etc/helphelp.pdf");

//Intentit=getWordFileIntent("/system/etc/help.doc");

//Intentit=getExcelFileIntent("/mnt/sdcard/Book1.xls")

//Intentit=getPptFileIntent("/mnt/sdcard/download/Android_PPT.ppt");//SD卡的download目录下

//Intentit=getVideoFileIntent("/mnt/sdcard/ice.avi");

//Intentit=getAudioFileIntent("/mnt/sdcard/ren.mp3");

//Intentit=getImageFileIntent("/mnt/sdcard/images/001041580.jpg");

//Intentit=getTextFileIntent("/mnt/sdcard/hello.txt",false);
