这里给大家分享我在网上总结出来的一些知识,希望对大家有所帮助
在AndroidManifest.xml注册ACTION事件
<activityandroid:name="com.test.app.MainActivity"android:configChanges="orientation|keyboardHidden|screenSize"android:label="这里的名称会对外显示"android:launchMode="singleTask"android:screenOrientation="portrait">//注册接收分享<intent-filter><action android:name="android.intent.action.SEND" /><category android:name="android.intent.category.DEFAULT" />//接收分享的文件类型<data android:mimeType="image/*" /><data android:mimeType="application/msword" /><data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" /><data android:mimeType="application/vnd.ms-excel" /><data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /><data android:mimeType="application/vnd.ms-powerpoint" /><data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" /><data android:mimeType="application/pdf" /><data android:mimeType="text/plain" /></intent-filter>//注册默认打开事件,微信、QQ的其他应用打开<intent-filter><action android:name="android.intent.action.VIEW" /><category android:name="android.intent.category.DEFAULT" />//接收打开的文件类型<data android:scheme="file" /><data android:scheme="content" /><data android:mimeType="image/*" /><data android:mimeType="application/msword" /><data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" /><data android:mimeType="application/vnd.ms-excel" /><data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /><data android:mimeType="application/vnd.ms-powerpoint" /><data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" /><data android:mimeType="application/pdf" /><data android:mimeType="text/plain" /></intent-filter></activity>
在用于接收分享的Activity里面加接收代码
- 当APP进程在后台时,会调用Activity的onNewIntent方法
- 当APP进程被杀死时,会调用onCreate方法
所以在两个方法中都需要监听事件
@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);receiveActionSend(intent);}@Overrideprotected void onNewIntent(Intent intent) {super.onNewIntent(intent);receiveActionSend(intent);}
receiveActionSend方法如下
public void receiveActionSend(Intent intent) {String action = intent.getAction();String type = intent.getType();//判断action事件if (type == null || (!Intent.ACTION_VIEW.equals(action) && !Intent.ACTION_SEND.equals(action))) {return;}//取出文件uriUri uri = intent.getData();if (uri == null) {uri = intent.getParcelableExtra(Intent.EXTRA_STREAM);}//获取文件真实地址String filePath = UriUtils.getFileFromUri(EdusohoApp.baseApp, uri);if (TextUtils.isEmpty(filePath)) {return;}//业务处理...}
获取真实路径getFileFromUri方法
/*** 获取真实路径** @param context*/public static String getFileFromUri(Context context, Uri uri) {if (uri == null) {return null;}switch (uri.getScheme()) {case ContentResolver.SCHEME_CONTENT://Android7.0之后的uri content:// URIreturn getFilePathFromContentUri(context, uri);case ContentResolver.SCHEME_FILE:default://Android7.0之前的uri file://return new File(uri.getPath()).getAbsolutePath();}}
Android7.0之后的uri content:// URI需要对微信、QQ等第三方APP做兼容
- 在文件管理选择本应用打开时,url的值为content://media/external/file/85139
- 在微信中选择本应用打开时,url的值为 content://com.tencent.mm.external.fileprovider/external/tencent/MicroMsg/Download/111.doc
- 在QQ中选择本应用打开时,url的值为 content://com.tencent.mobileqq.fileprovider/external_files/storage/emulated/0/Tencent/QQfile_recv/
第一种为系统统一文件资源,能通过系统方法转化为绝对路径;
微信、QQ的为fileProvider,只能获取到文件流,需要先将文件copy到自己的私有目录。
方法如下:
/*** 从uri获取path** @param uri content://media/external/file/109009* <p>* FileProvider适配* content://com.tencent.mobileqq.fileprovider/external_files/storage/emulated/0/Tencent/QQfile_recv/* content://com.tencent.mm.external.fileprovider/external/tencent/MicroMsg/Download/*/private static String getFilePathFromContentUri(Context context, Uri uri) {if (null == uri) return null;String data = null;String[] filePathColumn = {MediaStore.MediaColumns.DATA, MediaStore.MediaColumns.DISPLAY_NAME};Cursor cursor = context.getContentResolver().query(uri, filePathColumn, null, null, null);if (null != cursor) {if (cursor.moveToFirst()) {int index = cursor.getColumnIndex(MediaStore.MediaColumns.DATA);if (index > -1) {data = cursor.getString(index);} else {int nameIndex = cursor.getColumnIndex(MediaStore.MediaColumns.DISPLAY_NAME);String fileName = cursor.getString(nameIndex);data = getPathFromInputStreamUri(context, uri, fileName);}}cursor.close();}return data;}/*** 用流拷贝文件一份到自己APP私有目录下** @param context* @param uri* @param fileName*/private static String getPathFromInputStreamUri(Context context, Uri uri, String fileName) {InputStream inputStream = null;String filePath = null;if (uri.getAuthority() != null) {try {inputStream = context.getContentResolver().openInputStream(uri);File file = createTemporalFileFrom(context, inputStream, fileName);filePath = file.getPath();} catch (Exception e) {} finally {try {if (inputStream != null) {inputStream.close();}} catch (Exception e) {}}}return filePath;}private static File createTemporalFileFrom(Context context, InputStream inputStream, String fileName)throws IOException {File targetFile = null;if (inputStream != null) {int read;byte[] buffer = new byte[8 * 1024];//自己定义拷贝文件路径targetFile = new File(context.getExternalCacheDir(), fileName);if (targetFile.exists()) {targetFile.delete();}OutputStream outputStream = new FileOutputStream(targetFile);while ((read = inputStream.read(buffer)) != -1) {outputStream.write(buffer, 0, read);}outputStream.flush();try {outputStream.close();} catch (IOException e) {e.printStackTrace();}}return targetFile;}
