I'm developing a business profile page which contains profile image contact data and a photo gallery. I'm using Listview to check the urls from the received JSON data.
The problem is: the listview is not displayed on profile_layout. not inflated. Anyone can help?
Thanks a lot.
Here're the codes: ProfileActivity.java
private void getGalleryJSON(String url) {
listView = (ListView) findViewById(R.id.gallery_listview);
galleryAdapter = new GalleryAdapter(this, R.layout.gallery_layout);
listView.setAdapter(galleryAdapter);
class GetGalleryJSON extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... params) {
String uri2 = params[0];
BufferedReader bufferedReader = null;
try {
URL url = new URL(uri2);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
StringBuilder sb = new StringBuilder();
bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));
String json;
while((json = bufferedReader.readLine())!= null){
sb.append(json+"\n");
}
bufferedReader.close();
con.disconnect();
return sb.toString().trim();
}catch(Exception e){
return null;
}
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
gallery_json = s;
//TextView tv = (TextView)findViewById(R.id.gallery_content);
//tv.setText(gallery_json);
//=====================================
//======================================
// JSON OBJECT RECEIVED PERFECTLY
//======================================
//======================================
try {
gallery_jsonObject = new JSONObject(gallery_json);
gallery_jsonArray = gallery_jsonObject.getJSONArray("result");
int count = 0;
String thumb;
while (count < gallery_jsonArray.length()){
JSONObject JO = gallery_jsonArray.getJSONObject(count);
thumb = JO.getString("thumburl");
Gallery gallery = new Gallery(thumb);
galleryAdapter.add(gallery);
count++;
}
} catch (JSONException e1) {
e1.printStackTrace();
}
}
}
GetGalleryJSON ggj = new GetGalleryJSON();
ggj.execute(url);
}
This is the adapter GalleryAdapter.java
public class GalleryAdapter extends ArrayAdapter{
List list = new ArrayList();
public GalleryAdapter(Context context, int resource)
{
super(context, resource);
}
public void add(Profiles object) {
super.add(object);
list.add(object);
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return list.get(position);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row;
row = convertView;
GalleryHolder galleryHolder;
if(row == null){
LayoutInflater layoutInflater = (LayoutInflater)this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = layoutInflater.inflate(R.layout.gallery_layout, parent, false);
galleryHolder = new GalleryHolder();
galleryHolder.img_url = (TextView) row.findViewById(R.id.img_url);
row.setTag(galleryHolder);
}
else {
galleryHolder = (GalleryHolder) row.getTag();
}
Gallery gallery = (Gallery) this.getItem(position);
galleryHolder.img_url.setText(gallery.getUrl());
//=====================================
//======================================
// LATER I WILL USE THIS FOR IMAGEVIEW
//======================================
//===== //Picasso.with(this.getContext()).load(gallery.getUrl()).into(galleryHolder.img_url);
return row;
}
static class GalleryHolder{
TextView img_url;
}}
And this is the Gallery.java
public class Gallery {
private String url;
public Gallery(String url)
{
this.setUrl(url);
}
public void setUrl(String url){
this.url = url;
}
public String getUrl(){
return url;
}}
I use this layout on profile page
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fitsSystemWindows="true"
android:orientation="horizontal"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
screen-wide thumb
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:id="@+id/data">contact data
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:padding="10dp"
android:id="@+id/content">
<TextView
android:id="@+id/txt_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:editable="false"
android:text="Content" />
</LinearLayout>
<TextView
android:id="@+id/gallery_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Gallery"
android:textAlignment="center"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:padding="10dp"
android:id="@+id/gallery">
<ListView
android:id="@+id/gallery_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:columnWidth="100dp"
android:drawSelectorOnTop="true"
android:gravity="center"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="5dp"
android:focusable="true"
android:clickable="true"
android:background="#FF0000"
/>
</LinearLayout>
</LinearLayout>
</ScrollView>
And this is the gallery_layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="85dp">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/img_url"
/>
</RelativeLayout>
Note: I am using listview to check the urls only. I will change to GridView later
