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",

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:image animation using separate layout

I am building an app for wallpaper. I am trying get image from server. I am able to get image from server but when I am trying to animate and change image of imageview and it is work but it work in only in last 13 images not on all images.

It is because you use android:padding="5dp" in grid_single.xm in LinearLayout. If you want remove spaces you need use xml like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/grid_image"

android:layout_height="wrap_content"
android:gravity="center"></ImageView>

Here's my code, I'm getting these JSON Array values from my database. I just want to know how to change an image's src inside a list view. Because I will only use 5 images, I decided to include these images in my assets folder instead of uploading them to the web.
Can someone give me an idea to make this possible?
Here's my XML code:
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tvUserFullName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="12dip"
android:textStyle="bold"/>
//This is the imageView where I will display the image from the assets folder
<ImageView
android:id="#+id/ivUserRating"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:src="#drawable/zerostar"/>
</LinearLayout>
<TextView
android:id="#+id/tvUserEmail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="EmailAddress#domain.com"
android:textSize="9dip"/>
<TextView
android:id="#+id/tvUserComment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text='"This is a comment. This is a comment. This is a comment. This is a comment. This is a comment."'
android:textSize="10dip"
android:layout_margin="3dip"
android:textColor="#000000"
android:maxLength="300"/>
<TextView
android:id="#+id/tvDate"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="August 1, 2010"
android:textColor="#000000"
android:textSize="8dip"
android:layout_gravity="right"/>
<TextView
android:id="#+id/tvTime"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="08:20 PM"
android:textColor="#000000"
android:textSize="8dip"
android:layout_gravity="right"/>

Use SimpleAdapter as normal, but be sure to override you "adapter"'s the setViewBinder method like:
adapter.setViewBinder(new ViewBinder() {
public boolean setViewValue(View view, Object data,
String textRepresentation) {
// Check wether it's ImageView and the data
if(view instanceof ImageView && data instanceof Bitmap){
ImageView iv = (ImageView) view;
iv.setImageBitmap((Bitmap) data);
return true;
}else
return false;
}
});
then use a getBitmap() to get the assert image
public Bitmap getBitmap( String path, int i ){
Bitmap mBitmap = null;
try {
AssetManager assetManager = getAssets();
String[] files = null;
files = assetManager.list( "smartmodel/" + path );
Log.i( "Assert List", files[1].toString() );
// Pass ur file path, here is one in assert/smartmodel/ filer
mBitmap = BitmapFactory.decodeStream( this.getAssets().open( "smartmodel/" + path + "/"+ files[i]) );
} catch (Exception e) {
e.printStackTrace();
}
return mBitmap;
}
Last, in your Simple adapter List parameter, put
map.put( "ItemImage", getBitmap( gridItemName, i ));
Your passed getBitmap(...) will be show.

check position and use like,
Bitmap bmp=null;
if(position==0){
bitmap=getBitmap("img0.png");
}else if (position==1){
bitmap=getBitmap("img1.png");
}
.
.
.
Method::
private Bitmap getBitmap(String name) throws IOException
{
AssetManager asset = getAssets();
InputStream is = asset.open(name);
Bitmap bitmap = BitmapFactory.decodeStream(is);
return bitmap;
}

Scrolling is not perform in Listview in android
