android中打开本地doc、pdf、ppt、text等文件功能的实现

最近在做一个项目用到了打开本地的doc、pdf文件，对此做一个记录！希望有所帮助！

首先是一个打开各种格式文件的工具类，代码如下

import android.content.Intent;import android.net.Uri;import java.io.File;/** * Created by FengJD on 2016/11/10. */public class OpenFiles {    //android获取一个用于打开HTML文件的intent    public static Intent getHtmlFileIntent(String Path)    {        File file = new File(Path);        Uri uri = Uri.parse(file.toString()).buildUpon().encodedAuthority("com.android.htmlfileprovider").scheme("content").encodedPath(file.toString()).build();        Intent intent = new Intent("android.intent.action.VIEW");        intent.setDataAndType(uri, "text/html");        return intent;    }    //android获取一个用于打开图片文件的intent    public static Intent getImageFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "image/*");        return intent;    }    //android获取一个用于打开PDF文件的intent    public static Intent getPdfFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "application/pdf");        return intent;    }    //android获取一个用于打开文本文件的intent    public static Intent getTextFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "text/plain");        return intent;    }    //android获取一个用于打开音频文件的intent    public static Intent getAudioFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);        intent.putExtra("oneshot", 0);        intent.putExtra("configchange", 0);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "audio/*");        return intent;    }    //android获取一个用于打开视频文件的intent    public static Intent getVideoFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);        intent.putExtra("oneshot", 0);        intent.putExtra("configchange", 0);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "video/*");        return intent;    }    //android获取一个用于打开CHM文件的intent    public static Intent getChmFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "application/x-chm");        return intent;    }    //android获取一个用于打开Word文件的intent    public static Intent getWordFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "application/msword");        return intent;    }    //android获取一个用于打开Excel文件的intent    public static Intent getExcelFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "application/vnd.ms-excel");        return intent;    }    //android获取一个用于打开PPT文件的intent    public static Intent getPPTFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        Uri uri = Uri.fromFile(file);        intent.setDataAndType(uri, "application/vnd.ms-powerpoint");        return intent;    }    //android获取一个用于打开apk文件的intent    public static Intent getApkFileIntent(String Path)    {        File file = new File(Path);        Intent intent = new Intent();        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        intent.setAction(android.content.Intent.ACTION_VIEW);        intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");        return intent;    }}

这边是打开本地文件的界面，代码如下：
