изображение не обновляется после обновления

Question

новый ученик здесь. поэтому я только начал изучать андроид. более конкретно на изображении. и теперь я пытаюсь использовать библиотеку picasso. моя проблема в том, когда я использую picasso, новое изображение, которое я загрузил в базу данных, не обновляется на imageView (2.PreviewImage.java). делать помощь и tqvm в продвинутом режиме. FYI. При загрузке изображения в базу данных проблема не возникает.

1.MainActivity.java

    button = (Button)findViewById(R.id.btnSendSp); 
    button.setOnClickListener(this);

public void saveSpEmail(){ 
    SharedPreferences preferences = getSharedPreferences("PassingEmail", MODE_PRIVATE); 
    SharedPreferences.Editor editor = preferences.edit(); 
    editor.putString("passEmail", editText.getText().toString()); 
    editor.commit();

Answer 1

В PreviewImage.java внутри onResponse способа заменить

Picasso.with(PreviewImage.this) 
    .load(imagePath) 
    //.placeholder(R.drawable.placeholder) // optional 
    //.error(R.drawable.error)  // optional 
    .resize(400, 400)      // optional 
    .into(imageViewCoProfilePageClinicImage); 

с

runOnUiThread(new Runnable() { 
      @Override 
      public void run() { 
        Picasso.with(PreviewImage.this) 
        .load(imagePath) 
       //.placeholder(R.drawable.placeholder) // optional 
       //.error(R.drawable.error)  // optional 
        .resize(400, 400)      // optional 
        .into(imageViewCoProfilePageClinicImage); 
      } 
     });
