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);

Method getParcelableExtra() returns null when creating an intent

I have a problem regarding the creation of an intent and the handover of an object with the getParcelableExtra() method to it.
The aim of the project is the creation of a recycler view. If an item from the recycler is selected a new intent gets started and should display more detailed data.
Because the data is fetched from an external MySQL DB I'm using Volley for most of the networking stuff.
The recycler is implemented inside the Volley onResponse() method which is first called at app start (onCreate). Until this point everything works fine and the recycler is loaded and displayed correctly.
public class UserAreaActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_area);
initializeRecycler();
}
public void initializeRecycler() {
operations.getFoodFromDB(getFoodID(), new IDatabaseOperations() {
#Override
public void onSuccess(final ArrayList<Food> food_list) {
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
mLayoutmanager = new LinearLayoutManager(UserAreaActivity.this);
mAdapter = new FoodAdapter(food_list);
mRecyclerView.setLayoutManager(mLayoutmanager);
mRecyclerView.setAdapter(mAdapter);
mAdapter.setOnItemClickListener(new FoodAdapter.OnItemClickListener() {
#Override
public void OnItemClick(int position) {
Intent intent = new Intent(UserAreaActivity.this, FoodProfile.class);
GETS CORRECT OBJECT----->intent.putExtra("food", food_list.get(position));
startActivity(intent);
}
});
}
});
}
}
As you see I created an interface for the Volley onResponse method called onSuccess. Inside this method I am creating an onItemClickListener and this is where it gets ugly.
The onItemClickListener opens up the more detailed view of the item, but the method getParcelableExtra() returns NULL. Whatever I do it never returns an object of the class Food.
public class FoodProfile extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_food_profile);
Food food = getIntent().getParcelableExtra("food");<----RETURNS NULL
String price = food.getPrice();
String name = food.getName();
String rating = ((Float)food.getRating()).toString();
String imageRes = food.getmimgId();
TextView mPrice = (TextView) findViewById(R.id.Price);
mPrice.setText(price);
TextView mName = (TextView) findViewById(R.id.Name);
mName.setText(name);
TextView mRating = (TextView) findViewById(R.id.Rating);
mRating.setText(rating);
}
}
So the putExtra() works as intended and gets the correct object of the food class. But getParcelableExtra() returns NULL everytime. So no value is displayed in the started intent.
Food class:
public class Food implements Parcelable {
public int id;
public String name;
public String category;
public String date;
public int vegan;
public int vegetarian;
public String price;
public String uuid;
public float rating;
public String mimgId;
public Food(int id, String name, String category, int vegan, int vegetarian, String price, String uuid, float rating, String mimgId){
this.id = id;
this.name = name;
this.category = category;
this.date = date;
this.vegan = vegan;
this.vegetarian = vegetarian;
this.price = price;
this.uuid = uuid;
this.rating = rating;
this.mimgId = mimgId;
}
protected Food(Parcel in) {
id = in.readInt();
name = in.readString();
category = in.readString();
date = in.readString();
vegan = in.readInt();
vegetarian = in.readInt();
price = in.readString();
uuid = in.readString();
rating = in.readFloat();
mimgId = in.readString();
}
public static final Creator<Food> CREATOR = new Creator<Food>() {
#Override
public Food createFromParcel(Parcel in) {
return new Food(in);
}
#Override
public Food[] newArray(int size) {
return new Food[size];
}
};
public int getId() {
return id;
}
public String getName() {
if(name != null) {
name = name.replaceAll(System.getProperty("line.separator"), (""));
}
return name;
}
public String getDate() {
return date;
}
public int isVegan() {
return vegan;
}
public int isVegetarian() {
return vegetarian;
}
public String getPrice() {
return price;
}
public String getUuid() {
return uuid;
}
public float getRating(){return rating;}
public String getmimgId() {
return mimgId;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(price);
dest.writeString(name);
dest.writeString(((Float)rating).toString());
dest.writeString(mimgId);
}
}
Has anyone an idea whats causing the getParcelableExtra() to return null?
Thanks for your help in advance!

As I commented above, the writeToParcel() is problematic. The parcel should be written and read in the same order.

From Json To ViewPager

I'm trying to pass data from a json file to a viewpager. I have followed most of the advice previously given to me here but it returns blank, without even crashing.
The four files involved in this:
1. The main fragment:
public class FashionFeed extends Fragment {
ViewPager viewPager;
PagerAdapter adapter;
ThePagerAdapter newdapter;
public static final String URL =
"http://celebirious.com/bey/data/space.json";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_whats_hot, null);
// Locate the ViewPager in viewpager_main.xml
viewPager = (ViewPager) v.findViewById(R.id.pager);
viewPager.setClipToPadding(false);
viewPager.setPadding(4, 0, 4, 0);
int margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 20 * 2, getResources().getDisplayMetrics());
viewPager.setPageMargin(-margin);
new SimpleTask().execute(URL);
return v;
}
private class SimpleTask extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {
// Create Show ProgressBar
}
protected String doInBackground(String... urls) {
String result = "";
try {
HttpGet httpGet = new HttpGet(urls[0]);
HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
InputStream inputStream = response.getEntity().getContent();
BufferedReader reader = new BufferedReader
(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
result += line;
}
}
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
return result;
}
protected void onPostExecute(String jsonString) {
showData(jsonString);
}
}
private void showData(String jsonString) {
Gson gson = new Gson();
Style style = gson.fromJson(jsonString, Style.class);
List<Space> space = style.getSpace();
newdapter = new ThePagerAdapter(getActivity(), space);
viewPager.setAdapter(newdapter);
}
}
The Adapter extending the Pager:
public class ThePagerAdapter extends PagerAdapter {
List<Space> list;
LayoutInflater inflater;
Context context;
#Override
public int getCount() {
return list.size();
}
#Override
public boolean isViewFromObject(View view, Object object) {
return false;
}
public ThePagerAdapter(Context context,List<Space> list) {
this.list = list;
this.context = context; // red as well
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
// Declare Variables
TextView txtrank;
TextView txtcountry;
TextView txtpopulation;
ImageView imgflag;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.styledeets, container,
false);
// Locate the TextViews in viewpager_item.xml
txtrank = (TextView) itemView.findViewById(R.id.date);
txtcountry = (TextView) itemView.findViewById(R.id.where);
txtpopulation = (TextView) itemView.findViewById(R.id.info);
// Capture position and set to the TextViews
txtrank.setText(list.get(position).getName());
txtcountry.setText(list.get(position).getDates());
txtpopulation.setText(list.get(position).getInfo());
String url = (list.get(position).getAvatarUrl());
imgflag = (ImageView) itemView.findViewById(R.id.photo);
Picasso.with(context)
.load(url)
.placeholder(R.mipmap.ic_launcher)
.error(R.drawable.ic_launcher_gmail)
.fit()
.tag(context)
.into(imgflag);
// Locate the ImageView in viewpager_item.xml
// Capture position and set to the ImageView
//imgflag.setImageResource(flag[position]);
// Add viewpager_item.xml to ViewPager
((ViewPager) container).addView(itemView);
return itemView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((ViewPager) container).removeView((RelativeLayout) object);
}
}
Gson data retreived from jsonschema2pojo.org:
Space.java
public class Space {
#Expose

#Expose
private String type;
#Expose

public String getName() {
return name;
}
/**

}
/**

public String getDates() {
return dates;
}

public void setDates(String dates) {
this.dates = dates;
}
/**

public String getType() {
return type;
}
/**

}
/**

public void setAvatarUrl(String avatarUrl) {
this.avatarUrl = avatarUrl;
}
Lastly, Style.java
public class Style {
#Expose
private List<Space> space = new ArrayList<Space>();
/**
*
* #return
* The space
*/
public List<Space> getSpace() {
return space;
}
/**
*
* #param space
* The space
*/
public void setSpace(List<Space> space) {
this.space = space;
}
}
All the xml data is properly linked 'cause this all works when it is retrieving data locally. What could be wrong?

I figured this out !!!!! How silly of me.
Was
#Override
public boolean isViewFromObject(View view, Object object) {
return false;
}
should have been:
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((RelativeLayout) object);
}

Android: Exception Unmarshalling unknown type

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

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"
