在android中使用默认摄像头获取捕捉video的videopath

我正在为stringselectedImagePath声明一个全局variables。 点击button,我正在调用video捕捉代码

Intent intent=new Intent("android.media.action.VIDEO_CAPTURE"); intent.putExtra("android.intent.extra.durationLimit", 120); startActivityForResult(intent, REQUEST_VIDEO_CAPTURED); 

OnActivity结果我得到videopathselectedImagePath = getPath(selectedImageUri);

onActivityResult代码我在这里得到正确的值

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub if(resultCode==RESULT_OK) { if(requestCode==REQUEST_VIDEO_CAPTURED) { Toast.makeText(VideoPostActivity.this, "Video Recorded", Toast.LENGTH_LONG).show(); Uri selectedImageUri = data.getData(); selectedImagePath = getPath(selectedImageUri); System.out.println("selected image path"+selectedImagePath); /* imgPublishVideo.setEnabled(true); imgRecordVideo.setEnabled(false);*/ } } if(resultCode == RESULT_CANCELED) { Toast.makeText(VideoPostActivity.this, "Cancelled!", Toast.LENGTH_LONG).show(); } } 

我在这里没有得到价值

 SetMyVideoPostAsyncTask myVideoPostAsyncTask=new SetMyVideoPostAsyncTask(VideoPostActivity.this,videoTitle,videoComment,selectedImagePath); myVideoPostAsyncTask.execute(); public String getPath(Uri uri) { String[] projection = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(uri, projection, null, null, null); if(cursor!=null) { int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } else return null; } 

但我不能够通过selectedImagePath值从活动是空的任何人都可以告诉什么是问题? 我该怎么办?

试试这个:

 private String videoPath = ""; @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(resultCode==RESULT_OK) { Uri vid = data.getData(); videoPath = getRealPathFromURI(vid); } } public String getRealPathFromURI(Uri contentUri) { String[] proj = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(contentUri, proj, null, null, null); int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } 

managedQuery被弃用,我正在testingMarshmallow 6.0

所以你可以使用在Marshmallow 6.0和以前的较低版本上testing的FilePath类。 您必须通过FilePath.getPath(your_context, uri);来调用它FilePath.getPath(your_context, uri);

  import android.content.ContentUris; import android.content.Context; import android.database.Cursor; import android.net.Uri; import android.os.Build; import android.os.Environment; import android.provider.DocumentsContract; import android.provider.MediaStore; public class FilePath { public static String getPath(final Context context, String string) { return getPath(context, Uri.parse(string)); } public static String getPath(final Context context, final Uri uri) { final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT; // DocumentProvider if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) { // ExternalStorageProvider if (isExternalStorageDocument(uri)) { final String docId = DocumentsContract.getDocumentId(uri); final String[] split = docId.split(":"); final String type = split[0]; if ("primary".equalsIgnoreCase(type)) { return Environment.getExternalStorageDirectory() + "/" + split[1]; } // TODO handle non-primary volumes } // DownloadsProvider else if (isDownloadsDocument(uri)) { final String id = DocumentsContract.getDocumentId(uri); final Uri contentUri = ContentUris.withAppendedId( Uri.parse("content://downloads/public_downloads"), Long.valueOf(id)); return getDataColumn(context, contentUri, null, null); } // MediaProvider else if (isMediaDocument(uri)) { final String docId = DocumentsContract.getDocumentId(uri); final String[] split = docId.split(":"); final String type = split[0]; Uri contentUri = null; if ("image".equals(type)) { contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; } else if ("video".equals(type)) { contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI; } else if ("audio".equals(type)) { contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI; } final String selection = "_id=?"; final String[] selectionArgs = new String[] { split[1] }; return getDataColumn(context, contentUri, selection, selectionArgs); } } // MediaStore (and general) else if ("content".equalsIgnoreCase(uri.getScheme())) { return getDataColumn(context, uri, null, null); } // File else if ("file".equalsIgnoreCase(uri.getScheme())) { return uri.getPath(); } return null; } /** * Get the value of the data column for this Uri.
