我正在使用一个应用程序，该应用程序可以使用PHP WebService将不同的文件上传到服务器，我的问题是我可以上传诸如视频，图像和音频之类的文件，问题是我无法发送PDF，EXCEL或纯文本文件，当我尝试选择文件时，它甚至无法看到我必须能够发送的文本文件。
我尝试使用intent.setType（“ * / *”）;
我尝试通过setType（“ application / *”）更改setType（），也尝试使用setType（“ textplain / *”），但它们都不起作用
我使用的代码如下：
这是我使用INTENT的方法：
public void subirDocumento(){
Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(Intent.createChooser(intent, "Selecciona un archivo"), 4);
}
这是我用来恢复文件路径的代码：
@RequiresApi(api = Build.VERSION_CODES.KITKAT)
public static String getPath(final Context context, final Uri uri) {
// check here to KITKAT or new version
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];
}
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("com.android.providers.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())) {
Log.i("X","Valor: "+uri.getScheme());
return uri.getPath();
}
else if (isExternalStorageDocument(uri)){
Log.i("DOCUMENTO","Valor: "+uri.getScheme());
return getDataColumn(context, uri, null, null);
}
return null;
}
/**
* Get the value of the data column for this Uri. This is useful for
* MediaStore Uris, and other file-based ContentProviders.
*
* @param context

* @param uri
* The Uri to query.
* @param selection
* (Optional) Filter used in the query.

*/
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());
}
最后这是我在onActivityResult中的代码，如果我执行我的代码以将文件发送到服务器，则为其他代码：
else if(requestCode == 4 && resultCode == RESULT_OK){
Uri rutaFile = data.getData();
//Obtener toda la ruta del archivo
final String ruta = getPath(getApplicationContext(), rutaFile);
if(ruta != null){
Log.i("SOLID","Valor: "+ruta);
}
final ProgressDialog cargando = ProgressDialog.show(this, "Subiendo...","Espere por favor");
//Codigo para enviar
Thread t = new Thread(new Runnable() {
@Override
public void run() {
Log.i("SOLID", "Enviando: "+ruta);
File f = new File(ruta);
String content_type = getMimeType(f.getPath());
String file_path = f.getAbsolutePath();
OkHttpClient client = new OkHttpClient();
RequestBody file_body = RequestBody.create(MediaType.parse(content_type),f);
RequestBody request_body = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("type",content_type)
.addFormDataPart("uploaded_file",file_path.substring(file_path.lastIndexOf("/")+1), file_body)
.build();
okhttp3.Request request = new okhttp3.Request.Builder()
.url("http://192.168.1.75/webServ/save_file.php")
.post(request_body)
.build();
try {
okhttp3.Response response = client.newCall(request).execute();
if(!response.isSuccessful()){
throw new IOException("Error : "+response);
}
Log.i("PROBLEMA","Error: "+response);
cargando.dismiss();
} catch (IOException e) {
e.printStackTrace();
Log.i("PROBLEMA","Error: "+e.toString());
}
}
});
t.start();
}
我不明白为什么我无法选择文档以将其发送到服务器。
