获取Uri Android的真实路径

Question

我正在开发一个VideoPlayer.我将已URI启动的意图转换为字符串,它给了我content://media/external......但我需要得到真正的道路.

例如: /storage/extSdcard.....

我该怎么做呢？

如果需要,这是我的代码:

videoURI = getIntent().getData();
vv.setVideoURI(videoURI);

videoName = videoURI.toString();

tvTitle.setText(videoName);

Answer 1

使用此代码.这适用于所有Android版本.这是经过测试的代码.这支持所有设备

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];
                }

Answer 2

您可以将此代码用于选定的vedio路径.

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();

您可以参考以下链接获取帮助.

在 Kotlin 中，通过使用这个函数，我们可以从 URI 中获取真实路径：

这是代码 getRealPathFromURI

fun getRealPathFromURI(context: Context, uri: Uri): String? {
    when {
        // DocumentProvider
        DocumentsContract.isDocumentUri(context, uri) -> {
            when {
                // ExternalStorageProvider
                isExternalStorageDocument(uri) -> {
                    val docId = DocumentsContract.getDocumentId(uri)
                    val split = docId.split(":").toTypedArray()
                    val type = split[0]
                    // This is for checking Main Memory
                    return if ("primary".equals(type, ignoreCase = true)) {
                        if (split.size > 1) {
                            Environment.getExternalStorageDirectory().toString() + "/" + split[1]
                        } else {
                            Environment.getExternalStorageDirectory().toString() + "/"
                        }
                        // This is for checking SD Card
                    } else {
                        "storage" + "/" + docId.replace(":", "/")
                    }
                }
                isDownloadsDocument(uri) -> {
                    val fileName = getFilePath(context, uri)
                    if (fileName != null) {
                        return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName
                    }
                    var id = DocumentsContract.getDocumentId(uri)
                    if (id.startsWith("raw:")) {
                        id = id.replaceFirst("raw:".toRegex(), "")
                        val file = File(id)
                        if (file.exists()) return id
                    }
                    val contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), java.lang.Long.valueOf(id))

获取绕过 URI 的真实路径以getRealPathFromURI在您的活动或片段中发挥作用：

val fileRealPath = getRealPathFromURI(context!!, fileURI) ?: ""

Answer 4

这是我以前用过的东西:

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;
}

Answer 5

大多数答案不适用于画廊和相机图像。这对我有用。

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; 
} 

Answer 6

试试这个:

    @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

            }
        }

Answer 7

以下是如何通过 MediaStore 从 Uri 获取文件的真实路径：

private String getRealPathFromURI(Context context, Uri contentUri) {
    Cursor cursor = null;
    try {
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } catch (Exception e) {
        Log.e(TAG, "getRealPathFromURI Exception : " + e.toString());
        return "";
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}
