In View Pager nur die letzten Bilder von Json wiederholt in Android

Question

Ich habe Probleme beim Anzeigen von Bildern für Image Slider in Android.Ich hole die Bilder aus JSON aber immer nur das letzte Bild des Index anzeigen, Angenommen, wenn ich die verschieben kann Sehen Sie Pager immer wieder dasselbe Bild an, das für das Bildgleiten in Android anzeigt. Ich weiß nicht, was das Problem ist, versuchte ich fast wie ich kann, aber ich konnte diesen Fehler wirklich nicht finden. Wer hilft mein Problem zu lösen.

Code:

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_zoomproduct_); 
    options = new DisplayImageOptions.Builder() 
     .showStubImage(R.drawable.b2) 
     .showImageForEmptyUri(R.drawable.b2) 
     .showImageOnFail(R.drawable.b2) 
     .build(); 


    /******************** this is for single page product ***********************/ 

    Intent singleproductpage = getIntent(); 
    singlepro = singleproductpage.getStringExtra("currentinedx"); 
    Intent multipleimages = getIntent(); 
    multipleimg = multipleimages.getStringExtra("multipleimages"); 
    Intent productpath = getIntent(); 
    productpaths = productpath.getStringExtra("productpath"); 
    Intent seller = getIntent(); 
    sellers = seller.getStringExtra("sellerid"); 
    // pDialog = new ProgressDialog(Zoomproduct_Activity.this); 
    // pDialog.setMessage("Please wait..."); 
    // pDialog.setCancelable(false); 
    singleproduct(); 
    viewPager = (ViewPager) findViewById(R.id.pager); 
    // Pass results to ViewPagerAdapter Class 
    adapter = new ZoomAdapter(Zoomproduct_Activity.this, adlist); 
    // Binds the Adapter to the ViewPager 
    viewPager.setAdapter(adapter); 
    adapter.notifyDataSetChanged(); 
} 

multipleimage = new JSONArray(multiimg); 
if (multipleimage.length() > 0) { 
    for (int i = 0; i < multipleimage.length(); i++) { 

     JSONObject singleimg = multipleimage.getJSONObject(i); 
     /*oneimg = singleimg.getString("original_res"); 
     String singleImages= productpath+sid+ '/'+ oneimg;*/ 
     // zoom.setImageUrl(productpaths+sellers+ '/'+singleimg.getString("original_res")); 
     // imgs.add(zoom); 
     String imagesone = productpaths + sellers + '/' + singleimg.getString("original_res"); 
     map.put(TAG_IMAGE, imagesone); 
     adlist.add(map); 
     String imgs1 = String.valueOf(adlist); 
     //String zoom1=String.valueOf(imgs1); 
     // Log.d(zoom1,"zoom"); 
     Log.d(imgs1, "ararlist"); 

    } 
}

Glad zu schätzen mein Problem

Answer 1

Sie zu lösen, können dieändernbis ArrayList<String> wie es scheint HashMap ist nicht von Ihrem Code erforderlich.

Next in Ihrem for Schleife Sie, wo Sie Bildpfad zu HashMap hinzufügen, anstatt dass direkt hinzufügen ArrayList,

Und dann in getView() Ihrer PagerAdapter das Bild erhalten von ArrayList<>slideShowImages.get(position) verwenden,
