在我的应用中打开某种文件类型 [英] Open a certain file type in my app

问题描述

我的应用程序生成.smbf文件，当用户希望使用文件管理器应用程序打开文件时，我想选择在我的应用程序中打开这些文件.搜索之后，我发现了使用意图过滤器的方法，这是我的代码:

My app generates .smbf files and I want to make an option to open these files in my app when user want to open them using file manager apps. After searching I found a way using intent filter and this is my code:

[Android.App.Activity(Label = "Setting", Theme = "@style/MyTheme", WindowSoftInputMode = SoftInput.StateHidden, Icon = "@drawable/Icon")]
[Android.App.IntentFilter(actions: new string[] { Intent.ActionView, Intent.ActionEdit }, Categories = new string[] { Intent.CategoryDefault }, DataPathPattern = @".*\\.smbf", DataHost = "*", DataScheme = "file")]
public class Setting : MyActivity
{..}

生成的清单:

<activity android:icon="@drawable/icon" android:label="Setting" android:theme="@style/MyTheme" android:windowSoftInputMode="stateHidden|adjustUnspecified" android:name="md5307edafcc42f816474105a485627044f.Setting">
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <action android:name="android.intent.action.EDIT" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:host="*" android:pathPattern=".*\\.smbf" android:scheme="file" />
  </intent-filter>
</activity>

但是可以打开* .smbf文件的应用列表中没有显示我的应用.(已通过solid和es文件浏览器测试)我还有什么需要做的?

But my app isn't shown in the list of apps that can open *.smbf file. (tested with solid and es file explorers) Is there anything more that I should do?

推荐答案

添加mimeType属性后，我的问题已解决: DataMimeType ="*/*" android:mimeType ="*/*

My problem has been solved after I added mimeType attribute: DataMimeType = "*/*" android:mimeType="*/*
