Bildname in der Textansicht speichern

Question

Dies ist mein Code zum Speichern von Bildern in ImageView, aber ich möchte den Bildnamen in My TextView Object speichern. Bitte helfen Sie dabei.

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) { 

      filePath = data.getData(); 
      try { 

       bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath); 
       imageView.setImageBitmap(bitmap); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 

    public String getStringImage(Bitmap bmp){ 
     ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
     bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos); 
     byte[] imageBytes = baos.toByteArray(); 
     String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT); 
     return encodedImage; 
    }

Wenn ich auf geklickt mich nehmen jetzt eine Image-Datei zur Galerie wählen Sie Datei von hier zur Auswahl Ich möchte, dass, wenn ich Bild ausgewählt der Name von Bildshows in meiner Textansicht beschreibe mich bitte wie es geht.

Answer 1

Try Code unten, hoffen, dass es für Sie arbeitet

Sie ist kann Dateinamen von URI unter Code erhalten:

File file = getFile(context,filePath); 
String imageName = file.getName(); 
TextView.setText(imageName); 

hier ist die getFile Funktion,

public static File getFile(Context context, Uri uri) { 
     if (uri != null) { 
      String path = getPath(context, uri); 
      if (path != null && isLocal(path)) { 
       return new File(path); 
      } 
     } 
     return null; 
    } 

Answer 2

Aus Ihre Frage, die ich interpretierte, dass Sie den Bildnamen möchten, ist hier ein Code, um den Bildnamen von Ihrem Pfad zu erhalten. Stattdessen können Sie den gesamten Bildnamen und Pfad in einer separaten Hashmap speichern und später einen beliebigen Bildnamen mit dem entsprechenden Bildpfad erhalten.

public static String getImages(Context context) { 
       Uri uri; 
       Cursor cursor; 
       int column_index_data, column_index_file_name; 
       String PathOfImage = null; 
       uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI; 

       String[] projection = { MediaStore.MediaColumns.DATA, 
         MediaStore.MediaColumns.TITLE }; 
       //get you a cursor with which you can search all images in your device 
       cursor = context.getContentResolver().query(uri, projection, null, 
         null, null); 
       //get the column index of the Path of the image 
       column_index_data = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA); 
       //get the column index of the name of the image 
       column_index_file_name = cursor 
         .getColumnIndexOrThrow(MediaStore.MediaColumns.TITLE); 
       while (cursor.moveToNext()) { 
        PathOfImage = cursor.getString(column_index_data); 
        String name = cursor.getString(column_index_file_name); 
        Log.e("Manojit",PathOfImage+"\n"+name); 

        if(PathOfImage.equals(filepath)){ 
    //here you will get the title of the image 
    //from the result set the content of the Textview 
         return cursor.getString(column_index_file_name);} 
       } 
       return null; 
      }
