android 打开文本

一、OpenFiles类

 

package com.caojing.about;import java.io.File;import android.content.Intent;import android.net.Uri;public class OpenFiles {// android获取一个用于打开HTML文件的intentpublic static Intent getHtmlFileIntent(File file) {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intentpublic static Intent getImageFileIntent(File file) {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intentpublic static Intent getPdfFileIntent(File file) {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intentpublic static Intent getTextFileIntent(File file) {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intentpublic static Intent getAudioFileIntent(File file) {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intentpublic static Intent getVideoFileIntent(File file) {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intentpublic static Intent getChmFileIntent(File file) {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intentpublic static Intent getWordFileIntent(File file) {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intentpublic static Intent getExcelFileIntent(File file) {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intentpublic static Intent getPPTFileIntent(File file) {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intentpublic static Intent getApkFileIntent(File file) {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;}}

二、OpenFileHelper类

package com.caojing.about;import java.io.File;import com.caojing.mysharedemo.R;import android.content.ActivityNotFoundException;import android.content.Context;import android.content.Intent;import android.util.Log;import android.widget.Toast;public class OpenFileHelper{private Context context;public OpenFileHelper(Context context) {this.context = context;}public  void openFile(File currentPath){Log.d("OpenFileHelper",currentPath.toString());if (currentPath != null && currentPath.isFile()) {String fileName = currentPath.toString();Intent intent;try{if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingImage))) {intent = OpenFiles.getImageFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingWebText))) {intent = OpenFiles.getHtmlFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingPackage))) {intent = OpenFiles.getApkFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingAudio))) {intent = OpenFiles.getAudioFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingVideo))) {intent = OpenFiles.getVideoFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingText))) {intent = OpenFiles.getTextFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingPdf))) {intent = OpenFiles.getPdfFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingWord))) {intent = OpenFiles.getWordFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingExcel))) {intent = OpenFiles.getExcelFileIntent(currentPath);context.startActivity(intent);} else if (checkEndsWithInStringArray(fileName, context.getResources().getStringArray(R.array.fileEndingPPT))) {intent = OpenFiles.getPPTFileIntent(currentPath);context.startActivity(intent);} else {showMessage("无法打开，请安装相应的软件！");}}catch(ActivityNotFoundException e){showMessage("无法打开，请安装相应的软件！");}} else {showMessage("对不起，这不是文件！");}}private void showMessage(String msg){Toast.makeText(context, msg, Toast.LENGTH_LONG).show();}//检查文件类型是否在fileEndings.xml列表中private boolean checkEndsWithInStringArray(String checkItsEnd,String[] fileEndings) {for (String aEnd : fileEndings) {if (checkItsEnd.endsWith(aEnd))return true;}return false;}}

三、arrays.xml文件

 

<?xml version="1.0" encoding="utf-8"?><resources>    <array name="country_codes">        <item>-</item>        <item>AR</item>        <item>AU</item>        <item>BR</item>        <item>BG</item>        <item>CA</item>        <item>CN</item>        <item>CZ</item>        <item>DE</item>        <item>DK</item>        <item>ES</item>        <item>FI</item>        <item>FR</item>        <item>GB</item>        <item>GR</item>        <item>HU</item>        <item>ID</item>        <item>IT</item>        <item>JP</item>        <item>KR</item>        <item>NL</item>        <item>PL</item>        <item>PT</item>        <item>RU</item>        <item>SE</item>        <item>SK</item>        <item>SI</item>        <item>TR</item>        <item>TW</item>        <item>US</item>    </array>    <string-array name="array_checkbox">        <item>草约</item>        <item>确认</item>        <item>执行生效</item>        <item>发货完成</item>        <item>结算完成</item>        <item>合同完成</item>    </string-array>    <string-array name="array_checkbox_fzjdh">        <item>合同录入</item>        <item>合同审核</item>        <item>合同生效</item>        <item>合同生产</item>        <item>合同准发完成</item>        <item>合同发货完毕</item>        <item>合同结算完成</item>        <item>合同变更</item>        <item>合同完成</item>    </string-array>    <string-array name="bankroll_array_checkbox">        <item>草约</item>        <item>合同新增</item>        <item>合同已收款</item>        <item>合同生效</item>        <item>发货完成</item>        <item>结算完成</item>    </string-array>    <array name="fileEndingImage">        <item>.png</item>        <item>.gif</item>        <item>.jpg</item>        <item>.jpeg</item>        <item>.bmp</item>        <item>.tif</item>        <item>.tiff</item>    </array>    <array name="fileEndingAudio">        <item>.mp3</item>        <item>.wav</item>        <item>.ogg</item>        <item>.midi</item>    </array>    <array name="fileEndingVideo">        <item>.mp4</item>        <item>.rmvb</item>        <item>.avi</item>        <item>.flv</item>    </array>    <array name="fileEndingPackage">        <item>.jar</item>        <item>.zip</item>        <item>.rar</item>        <item>.gz</item>        <item>.apk</item>        <item>.img</item>    </array>    <array name="fileEndingWebText">        <item>.htm</item>        <item>.html</item>        <item>.php</item>        <item>.jsp</item>    </array>    <array name="fileEndingText">        <item>.txt</item>        <item>.java</item>        <item>.c</item>        <item>.cpp</item>        <item>.py</item>        <item>.xml</item>        <item>.json</item>        <item>.log</item>    </array>    <array name="fileEndingWord">        <item>.doc</item>        <item>.docx</item>    </array>    <array name="fileEndingExcel">        <item>.xls</item>        <item>.xlsx</item>    </array>    <array name="fileEndingPPT">        <item>.ppt</item>        <item>.pptx</item>    </array>    <array name="fileEndingPdf">        <item>.pdf</item>    </array>    <array name="gbfwType">        <item>产品</item>        <item>物流</item>        <item>财务</item>        <item>系统</item>        <item>其他</item>        <item>异议</item>    </array>    <array name="gbfwStatus">        <item>待处理</item>        <item>处理中</item>        <item>完成</item>    </array>   <array name="region">        <item>总部</item>        <item>东北区域</item>        <item>华北区域</item>        <item>华东地区</item>         <item>华中区域</item>        <item>西部区域</item>         <item>南方区域</item>        <item>专营公司</item>    </array></resources>
