我在Oracle的VirtualBox中使用VM =“WSVGA 7.0 Tablet - 4.2.2 - API17”进行测试
我无法使用此代码使用Intent连接到应用程序:
Intent intent = new Intent("com.estrongs.action.PICK_FILE"); Intent intent = new Intent("com.example.filechooser.PICK_DIRECTORY"); // intent.setDataAndTypeAndNormalize(Uri.parse("file://"), "*/*"); //No Activity found to handle Intent { act=com.estrongs.action.PICK_FILE dat=file:// typ=*/* } //No Activity found to handle Intent { act=com.estrongs.action.PICK_FILE } // intent.setType("*/*"); //No Activity found to handle Intent { act=com.estrongs.action.PICK_FILE typ=file/* } //No Activity found to handle Intent { act=com.estrongs.action.PICK_FILE typ=*/* } // NOTE: Extra space at end of action above. removed below //No Activity found to handle Intent { act=com.estrongs.action.PICK_FILE typ=*/* } //No Activity found to handle Intent { act=com.example.filechooser.PICK_DIRECTORY typ=*/* } //No Activity found to handle Intent { act=com.example.filechooser.PICK_DIRECTORY }
// startActivityForResult(intent, FolderChosen);

来自我的AndroidManifest.xml:
<intent-filter> <action android:name="android.intent.action.VIEW" /> <action android:name="android.intent.action.SEND" /> <action android:name="android.intent.action.GET_CONTENT" /> <category android:name="android.intent.category.OPENABLE" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:mimeType="*/*" /> </intent-filter> <intent-filter> <action android:name="com.example.filechooser.PICK_DIRECTORY" /> </intent-filter>
&GT; 我确实让这个工作:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setDataAndTypeAndNormalize(Uri.parse(“file://”),“ / ”); // file:// WORKED
// onCreate intent=Intent { act=android.intent.action.GET_CONTENT dat=file:// typ=*/*
// flg=0x3000000 cmp=com.example.filechooser/.FileChooser } <<<<<<<<<<<<<NOTE: WORKED
我应该如何编写可以由以下意图选择的intent-filter:
Intent intent = new Intent(“com.estrongs.action.PICK_FILE”); Intent intent = new Intent(“com.example.filechooser.PICK_DIRECTORY”);
答案 0 :(得分:2)
<intent-filter>
<action android:name="com.estrongs.action.PICK_FILE" />
<action android:name="com.example.filechooser.PICK_DIRECTORY" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.OPENABLE" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
我假设您接受所有MIME类型,因为您的元素包含“ / ”,所以我建议您省略该元素。默认情况下,如果不存在过滤器元素(即),Android将匹配任何值。
