Android中调用第三方打开本地doc、pdf、ppt、text等文件功能的实现

本文主要是介绍Android中调用第三方打开本地doc、pdf、ppt、text等文件功能的实现，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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;  public class FileUtils {  //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;  }
