I'm sorry, my question was just one row appear
and in my project image_url1,2,3,4,5 is act on another activity by intent, and it works well already
i can't upload image, please look below picture
┌──────┐┌──────┐┌──────┐┌──────┐┌──────┐
│■■■■■■││ ││ ││ ││ │
│■■■■■■││ ││ ││ ││ │
└──────┘└──────┘└──────┘└──────┘└──────┘
only first url parsing works another didn't....
(first box parsed to image_url, when it clicks image_url1,2,3,4,5 appear)
i want all rows appear, not one row
before i ask question, i need to learn English more......
I want these json array response on my application imagebuttons(or gridview)
i get an array of images from WAS and each row data act as button
json array is here
{
"total" : 2,
"row" : [
{
"id": "c3asfasfas35sd4a35as5d4a3",
"image_name": "20150913151562135",

but i try this code, only the first image show, another didn't appear
help me!!
receive just one data sheet (one row) is success. i don't know how to receive total row data.... please help me. save my life please

Try this Code Its Work..
HttpEntity entity = response.getEntity();
String resJson = EntityUtils.toString(entity);
System.out.println("**** = " + resJson);
jsonStr = resJson;
JSONTokener jsonParser = new JSONTokener(resJson);
JSONObject itemList = (JSONObject) jsonParser.nextValue();
int total = itemList.getInt("total");
int currentPage = itemList.getInt("currentPage");
JSONArray jsonObjs = itemList.getJSONArray("rows");
String demoUrl = "";
String s = "";
List<String> imageUrlList = new ArrayList<String>();
for (int i = 0; i < jsonObjs.length(); i++) {
JSONObject jsonObj = jsonObjs.getJSONObject(i);
// String id = jsonObj.getInt("id");
String image_name = jsonObj.getString("image_name");
String image_url = jsonObj.getString("image_url");
String image_url1 = jsonObj.getString("image_url1");
String image_url2 = jsonObj.getString("image_url2");
String image_url3 = jsonObj.getString("image_url3");
String image_url4 = jsonObj.getString("image_url4");
String image_url5 = jsonObj.getString("image_url5");
String image_url6 = jsonObj.getString("image_url6");
String price = jsonObj.getString("price");
imageUrlList.add(image_url);
imageUrlList.add(image_url1);
imageUrlList.add(image_url2);
imageUrlList.add(image_url3);
imageUrlList.add(image_url4);
imageUrlList.add(image_url5);
imageUrlList.add(image_url6);

Because you add just one image_url in your list.
If you want to add all url in list you have to do like below,
imageUrlList.add(image_url);
imageUrlList.add(image_url1);
imageUrlList.add(image_url2);
imageUrlList.add(image_url3);
imageUrlList.add(image_url4);
imageUrlList.add(image_url5);
imageUrlList.add(image_url6);
But Instead of this,
Better way is to create JSONArray of your all Images.

Android while using cardview image is loading very lazy

I am loading pictures (below ~3MB in size) into Cardview from a database and it was infalte in Listviewstview.
The loading and browsing of these pictures is way too slow.
Is there any method to downscale these pictures to speed up & sometimes dispalyind [Duplicate] images on other card view?

Try scale your bitmap to lower its actual resolution, I've used the following codes to reduce bitmap's size.
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
For you case, add the following codes into your adapter class AsyncTask's doInBackground method
try {
bitmap = BitmapFactory.decodeStream((InputStream) new URL(args[0]).getContent());
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
} catch (Exception e) {
e.printStackTrace();
}
return scaled;
Return scaled bitmap instead of original bitmap.

Scrolling is not perform in Listview in android

I have a problem that, I am adding listview in LinearLayout dynamically through code and set the EndlessAdapter into that, Data is shown correctly but we are unable to scroll from top to bottom in the list. I don't know why? please suggest me any solution regarding the same.
Code:

Thanks in adavance.

Try adding a ScrollView in the xml file.

cannot setvisibility in listview

Here is to control visibility of the layout
if (!(imagepath[i].toString().equals("no picture"))) {
try {
aURL = new URL("http://www.orientaldaily.com.my/"
+ imagepath[i]);
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
Bitmap bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
layout_image.setVisibility(View.VISIBLE);
imageview.setVisibility(View.VISIBLE);
imageview.setScaleType(ScaleType.CENTER_CROP);
imageview.setImageBitmap(bm);
} catch (IOException e) {
Log.e("DEBUGTAG", "Remote Image Exception", e);
}
}
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps,
R.layout.main_alllatestnewslist, from, to);
lv.setAdapter(adapter);
Here is to initialize it
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_alllatestnews);
lv = (ListView) findViewById(android.R.id.list);
RelativeLayout temp = (RelativeLayout)findViewById(R.id.layout_temp);
LayoutInflater liInflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
temp.addView(liInflater.inflate(R.layout.main_alllatestnewslist, null));
Here is the main_alllatestnews.xml
<LinearLayout
android:id="#+id/layout_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#id/layout_menu"
android:layout_below="#id/layout_title"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Here is the main_alllatestnewslist.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_temp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_news_list" >
<LinearLayout
android:id="#+id/layout_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10px"
android:layout_marginTop="10px" >
<ImageView
android:id="#+id/image_alllatestnewstitle"
android:layout_width="134px"
android:layout_height="80px"
android:src="#drawable/image_loading_failed_1"
android:visibility="invisible" />
</LinearLayout>
When i run this, it gave me Nullpointerexception at line
temp.addView(liInflater.inflate(R.layout.main_alllatestnewslist, null)); <-- inflater still null...
How to solve this?

Change
setContentView(R.layout.main_alllatestnews);
to
setContentView(R.layout.main_alllatestnewslist);
because layout_image is in layout main_alllatestnewslist
Edited:
LayoutInflater liInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
yourView.addView(liInflater.inflate(R.layout.main_alllatestnewslist, null))
something like that.
