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;
}

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.

Display full screen image in ImageView

I want to display full screen image on another activity after clicking an imageview. I have 6 ImageViews in my layout and each ImageView is getting image from Parse backend. How can I display image on fetching the imagepath ?
public ImageLoader imgl;
ImageView ad1,ad2,ad3,ad4,ad5,ad6;
List<ParseObject> ob;
private ImageView[] imgs = new ImageView[5];
int k=0;
ad1=(ImageView) findViewById(R.id.ad1);
ad2=(ImageView) findViewById(R.id.ad2);
ad3=(ImageView) findViewById(R.id.ad3);
ad4=(ImageView) findViewById(R.id.ad4);
ad5=(ImageView) findViewById(R.id.ad5);
ad6=(ImageView) findViewById(R.id.ad6);
imgs[0] = ad2;
imgs[1] = ad3;
imgs[2] = ad4;
imgs[3] = ad5;
imgs[4] = ad6;
ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Adverts");
query.orderByDescending("updatedAt");
query.whereEqualTo("Status", true);
try {
ob = query.find();
System.out.println("the urls areeee "+ob);
for (ParseObject country : ob) {
ParseFile image = (ParseFile) country.get("imageFile");
imgl.DisplayImage(image.getUrl(), imgs[k]);
k=k+1;
System.out.println("the urls are"+image.getUrl());
pd.dismiss();
}
} catch (com.parse.ParseException e) {
// TODO Auto-generated catch block
pd.dismiss();
e.printStackTrace();
}
ad1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent ent= new Intent(HomeActivity.this,AdvertsActivity.class);
startActivity(ent);
}
});
}

Set click listener on your ImageView and pass your image url in argument and call method
private void viewImage(String url)
{

nagDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

ivPreview = (ImageView)nagDialog.findViewById(R.id.imageView1);
BitmapDrawable bmd = (BitmapDrawable)getDrawableFromUrl(url)
Bitmap bitmap = bmd.getBitmap();
ivPreview.setImageBitmap(bitmap);
nagDialog.show();
}
public Drawable getDrawableFromUrl(String imgUrl)
{
if(imgUrl == null || imgUrl.equals(""))
return null;
try
{
URL url = new URL(imgUrl);
InputStream in = url.openStream();
Drawable d = Drawable.createFromStream(in, imgUrl);
return d;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}

Please Help me.

You are not setting the adapter again in onTextChange. Add this inside onTextChange at the end:
setListAdapter(searchResult);
and remove
adapter.notifyDataSetChanged();
