Cannot display images in Html.fromHtml() in text view for images coming dynamically

I am developing an app in android studio in which contents are coming form an Api in a recyclerview. In the api there is an element "content" that sends all html tags with images like a full page. I have to display that page in textview. I have tried Htm.fromHtml method but it is not displaying the images. I have searched all answers and got the solution of ImageGetter method, but I am not able to display dynamic content in the recycleradapter from ImageGetter. I have to keep the images in the drawable of my app and match the source URL that is being parsed. Please help. Below is my code.

I also faced a similar problem month ago and used this and it works fine :
String htmlData = listData.get(position).getValue();
String showData = htmlData.replace("\n", "");
URLImageParser p = new URLImageParser(holder.textt, context);
Spanned htmlAsSpanned = Html.fromHtml(showData,p,null);
holder.yourTextView.setText(htmlAsSpanned);
Now copy and paste these 2 methods :
First method :
public class URLDrawable extends BitmapDrawable {
protected Drawable drawable;
#Override
public void draw(Canvas canvas) {
if(drawable != null) {
drawable.draw(canvas);
}
}
}
///Second Method :
public class URLImageParser implements Html.ImageGetter {
Context c;
TextView container;
/***
* Construct the URLImageParser which will execute AsyncTask and refresh the container
* #param t
* #param c
*/
public URLImageParser(TextView t, Context c) {
this.c = c;
this.container = t;
}
public Drawable getDrawable(String source) {
URLDrawable urlDrawable = new URLDrawable();
// get the actual source
ImageGetterAsyncTask asyncTask =
new ImageGetterAsyncTask( urlDrawable);
asyncTask.execute(source);
// return reference to URLDrawable where I will change with actual image from
// the src tag
return urlDrawable;
}
public class ImageGetterAsyncTask extends AsyncTask<String, Void, Drawable> {
URLDrawable urlDrawable;
public ImageGetterAsyncTask(URLDrawable d) {
this.urlDrawable = d;
}
#Override
protected Drawable doInBackground(String... params) {
String source = params[0];
return fetchDrawable(source);
}
#Override
protected void onPostExecute(Drawable result) {
// set the correct bound according to the result from HTTP call
urlDrawable.setBounds(0, 0, 0 + result.getIntrinsicWidth(), 0
+ result.getIntrinsicHeight());
// change the reference of the current drawable to the result
// from the HTTP call
urlDrawable.drawable = result;
// redraw the image by invalidating the container
URLImageParser.this.container.invalidate();
URLImageParser.this.container.setHeight((URLImageParser.this.container.getHeight()
+ result.getIntrinsicHeight()));
}
/***
* Get the Drawable from URL
* #param urlString
* #return
*/
public Drawable fetchDrawable(String urlString) {
try {
InputStream is = fetch(urlString);
Drawable drawable = Drawable.createFromStream(is, "src");
drawable.setBounds(0, 0, 0 + drawable.getIntrinsicWidth(), 0
+ drawable.getIntrinsicHeight());
return drawable;
} `enter code here`catch (Exception e) {
return null;
}
}
private InputStream fetch(String urlString) throws MalformedURLException, IOException {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(urlString);
HttpResponse response = httpClient.execute(request);
return response.getEntity().getContent();
}
}
}

try this
load your image using piccaso
add below library in your build.gradle
implementation 'com.squareup.picasso:picasso:2.71828'
when you need to set image use piccaso this way
Picasso.get()
.load(your_image)
.placeholder(R.drawable.user_placeholder)
.error(R.drawable.your_error_image_or_blank)
.into(your_imageView);

P.S. I would share github link but I should give you my personal API key. :(

You need to start the AsyncTask in onCreate() (like you did before) and in finished() you take the results and add them to the Adapter's data list.
Finally, don't forget to call notifyDatasetChanged().
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_movie_details);
// skipping some lines of code here...
mReviewRecycle.setAdapter(mReviewAdapter);
ReviewAsyncTask reviewAsyncTask = new ReviewAsyncTask(this);
reviewAsyncTask.execute();
}
#Override
public void finished(ArrayList<ReviewData> output) {
mReviewList.addAll(output);
mReviewAdapter.notifyDatasetChanged();
}
(Please note that I skipped null checks and error handling for brevity's sake)

In MovieDetails onCreate retrieve current movie ID like you do in displayMovieDetail.
Send that ID to ReviewAsyncTask (you'll need to modify constructor of ReviewAsyncTask)
Retrieve id in ReviewAsyncTask, save it as member variable, and then in doInBackground method send that id to buildReviewUrl as an argument.

Broadcast receiver in BaseAdaper

I want to update a textview into a listView when i get my current position (GPS).
So i send a broadcast in my activity when i had my position. In my listViewAdapter, i have a receiver who set text. But i don't know where i can registrer and unregistrer my broadcast.
May be there is an other solution to send parameter to my listViewAdapter when my current position is available.

** ANSWER : **
public void updateEstablishmentList(ArrayList<Establishment> newlist) {
establishmentsList = newlist;
this.notifyDataSetChanged();
}

You shouldn't put the BroadcastReceiver in the Adapter, it doesn't belong there. Put it in the Activity or Fragment which contains the ListView. To pass a new location to the ListView you need to implement a method to set the location to a specific row in the Adapter:
Of course your class Establishment needs to contain a field to store the Location along with appropriate getters and setters:
public void setLocationAtPosition(int position, Location location) {
Establishment e = (Establishment) getItem(position);
e.setLocation(location);
notifyDataSetChanged();
}
And in getView() of your Adapter:
Establishment e = (Establishment) getItem(position);
if (e != null) {
holder.Name.setText(e.getName());
holder.Description.setText(e.getDescription());
Location location = e.getLocation();
double longitude = location.getLongitude();
double latitude = location.getLatitude()
holder.Distance.setText(longitude + "/" + latitude);
}

Android: Exception Unmarshalling unknown type

I have to pass a ArrayList from one activity to another activity. So I use
intent.putParcelableArrayListExtra("Items",sendinglist);
And I get the sendinglist through
ArrayList<GeoItem> revd = new ArrayList<GeoItem>();
Bundle b = getIntent().getExtras();
if (b != null)
revd = b.getParcelableArrayList("Items");
Log.i("Element details",revd.get(0).getLatitude()+"");// Error
But i cant access the GeoItem object in that list.
UPDATE the class based on the answers...
My GeoItem class is
public class GeoItem implements Parcelable, Serializable {
/** id of item. */
protected long id_;
/** item location in GeoPoint. */

Please provide me the best way...

GeoPoint is not a Parceable therefore it can be marshalled. You may want to save the data somehow without GeoPoint or extend GeoPoint so it implements Parceable

**To pass an arraylist of Category to another activity,**
intent i = new Intent(_av.getContext(), ItemList.class);
Bundle b = new Bundle();
b.putParcelableArrayList("categories", categories);
b.putInt("index", _index);
i.putExtras(b);
startActivityForResult(i, ITEM_LIST);
**To retrieve the data,**
Bundle b = this.getIntent().getExtras();
ArrayList<Category> cats = b.getParcelableArrayList("categories");
int index = b.getInt("index");

My actual task is to send the list of GeoItems object through intent. Also My GeoItems class is serializable . Obviously list of serializable object is also serialibale So I used,
Intent listview = new Intent(context, ReportList.class);
Bundle send = new Bundle();
send.putSerializable("Items", (Serializable) items);
listview.putExtras(send);
context.startActivity(listview);
where items is a list of GeoIems objects
And in receiving activity,
Bundle b = this.getIntent().getExtras();
if (b != null) {
data = (List<GeoItem>) b.getSerializable("Items");
}
where data is a list of GeoIems objects
Without using Parceable interface, now i can set my list of serializable objects through intent to next activity

error when setting an onclick to a listview/json

I'm getting a json exception when I try to run my code.
The problem happens on the onclick listener. I'm trying to have the application go to the article of the rss feed on click
Here is the main activity
public class Blocku extends ListActivity {
private RssListAdapter adapter;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
List<JSONObject> jobs = new ArrayList<JSONObject>();
try {
jobs = BlockuReader.getLatestRssFeed();
} catch (Exception e) {
Log.e("RSS ERROR", "Error loading RSS Feed Stream >> " + e.getMessage() + " //" + e.toString());
}
adapter = new RssListAdapter(this,jobs);
setListAdapter(adapter);
}
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
String link = null;
try {
String url = Article.getUrl().toString();
link = adapter.getItem(position).getString(url).toString();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(link));
startActivity(i);
} catch (JSONException e) {
Context context = getApplicationContext();
CharSequence text = "error";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
e.printStackTrace();
}
}
}
here is the adapter:
public class RssListAdapter extends ArrayAdapter<JSONObject> {
public RssListAdapter(Activity activity, List<JSONObject> imageAndTexts) {
super(activity, 0, imageAndTexts);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Activity activity = (Activity) getContext();
LayoutInflater inflater = activity.getLayoutInflater();
// Inflate the views from XML
View rowView = inflater.inflate(R.layout.image_text_layout, null);
JSONObject jsonImageText = getItem(position);
//////////////////////////////////////////////////////////////////////////////////////////////////////
//The next section we update at runtime the text - as provided by the JSON from our REST call
////////////////////////////////////////////////////////////////////////////////////////////////////
TextView textView = (TextView) rowView.findViewById(R.id.job_text);
try {
Spanned text = (Spanned)jsonImageText.get("text");
textView.setText(text);
} catch (JSONException e) {
textView.setText("JSON Exception");
}
return rowView;
}
}
and the article class
public class Article {
private long articleId;
private long feedId;
private String title;
private String description;
private String pubDate;
private static URL url;
private String encodedContent;
private static String link;
/**
* #return the articleId
*/
public long getArticleId() {
return articleId;
}
/**
* #param articleId the articleId to set
*/
public void setArticleId(long articleId) {
this.articleId = articleId;
}
/**
* #return the feedId
*/
public long getFeedId() {
return feedId;
}
/**
* #param feedId the feedId to set
*/
public void setFeedId(long feedId) {
this.feedId = feedId;
}
/**
* #return the title
*/
public String getTitle() {
return title;
}
/**
* #param title the title to set
*/
public void setTitle(String title) {
this.title = title;
}
/**
* #return the url
*/
public static URL getUrl() {
return url;
}
/**
* #param url the url to set
*/
public void setUrl(URL url) {
Article.url = url;
}
/**
* #param description the description to set
*/
public void setDescription(String description) {
this.description = description;
}
/**
* #return the description
*/
public String getDescription() {
return description;
}
/**
* #param pubDate the pubDate to set
*/
public void setPubDate(String pubDate) {
this.pubDate = pubDate;
}
/**
* #return the pubDate
*/
public String getPubDate() {
return pubDate;
}
/**
* #param encodedContent the encodedContent to set
*/
public void setEncodedContent(String encodedContent) {
this.encodedContent = encodedContent;
}
/**
* #return the encodedContent
*/
public String getEncodedContent() {
return encodedContent;
}
}

JSONException is usually thrown when there are issues with parsing. Check how you are parsing the JSON. this says that you are trying to get a value for a key named "then it lists the site i want"
