我開發一個VideoPlayer。我轉換推出意圖字符串的URI，這讓我content://media/external.....。但我需要得到真正的道路。獲取真實路徑對於開放的安卓
例如：/storage/extSdcard....。
我該怎麼做？
這裏是我的代碼，如果需要的話：
videoURI = getIntent().getData();
vv.setVideoURI(videoURI);
videoName = videoURI.toString();
tvTitle.setText(videoName);
試試這個：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
System.out.println("picturePath +"+ picturePath); //path of sdcard
}
}
您可以使用所選錄象路徑此代碼。
Uri uri = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String yourRealPath = cursor.getString(columnIndex);
} else {
//boooo, cursor doesn't have rows ...
}
cursor.close();
您可以參考下面的鏈接尋求幫助。
Get filename and path from URI from mediastore
我希望你會成功。
這裏的東西之前，我已經使用：
public String getRealPathFromURI (Uri contentUri) {
String path = null;
String[] proj = { MediaStore.MediaColumns.DATA };
Cursor cursor = getContentResolver().query(contentUri, proj, null, null, null);
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
path = cursor.getString(column_index);
}
cursor.close();
return path;
}
我發現了更多的優雅的解決方案：
Uri file_uri = Uri.parse(videoURI); // parse to Uri if your videoURI is string
String real_path = file_uri.getPath(); // will return real file path
這樣稱呼它
Uri selectedImageURI = data.getData(); //where data is intent return by onActivityResult
imageFile = new File(getRealPathFromURI(selectedImageURI));
和代碼gettingPath ..
private String getRealPathFromURI(Uri contentURI)
{
String result = null;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null)
{ // Source is Dropbox or other similar local file path
result = contentURI.getPath();
}
else
{
if(cursor.moveToFirst())
{
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
}
cursor.close();
}
return result;
}
大部分的答案不工作兩個畫廊和相機圖像。這對我有用。
public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
Log.i("URI",uri+"");
String result = uri+"";
// DocumentProvider
// if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
if (isKitKat && (result.contains("media.documents"))) {
String[] ary = result.split("/");
int length = ary.length;
String imgary = ary[length-1];
final String[] dat = imgary.split("%3A");
final String docId = dat[1];
final String type = dat[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
} else if ("audio".equals(type)) {
}
final String selection = "_id=?";
final String[] selectionArgs = new String[] {
dat[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
} else if ("content".equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
使用此代碼。這是工作所有Android version.This測試代碼。此支持的所有設備
public static String getPathFromUri(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 the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection,
String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is ExternalStorageProvider.
*/
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is DownloadsProvider.
*/
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is MediaProvider.
*/
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is Google Photos.
*/
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
在這裏，我得到的URI從onActivityResult（）
Uri selectedImageURI = data.getData();
String realPath = getRealPathFromURI(selectedImageURI);
1）在片段中你可以使用像這樣的功能..
private String getRealPathFromURI(Uri contentURI) {
String filePath;
Cursor cursor = getActivity().getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) {
filePath = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
filePath = cursor.getString(idx);
cursor.close();
}
return filePath;
}
2）和活動，你可以使用這樣的功能。
private String getRealPathFromURI(Uri contentURI) {
String filePath;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) {
filePath = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
filePath = cursor.getString(idx);
cursor.close();
}
return filePath;
}
當'DocumentsContract'本身僅在API級別19 KitKat後纔可用時，這是如何工作在所有Android版本上的？ https://developer.android.com/reference/android/provider/DocumentsContract.html –
使用此代碼，那麼你會知道這是工作中的所有設備，並根據API級別有狀態。 –
