I have a url as
eg: http://movie.org/movie/popular?api_key=c68&page=1
Right now I am able to display for page 1 alone,my question is how to change page and display in listview when scrolling. Right now I am able to display for first page. But I couldn't proceed where to increment page and use it.
My code is as follows:
int page=1; // i don't know where to add increment of this page and display.
private class MovieTop extends AsyncTask {
@Override
protected ArrayList<HashMap<String, String>> doInBackground(
Object... params) {
try {
return displayTopMovies();
} catch (IOException e) {
return null;
}
}
public ArrayList<HashMap<String, String>> displayTopMovies()
throws IOException {
StringBuilder stringBuilder = new StringBuilder();
stringBuilder
.append("https://movie.org/movie/popular?");
stringBuilder.append("?api_key=" + "c68"+"&&"+page);
// right now i am displaying for page 1 alone. I have issue where to add page++ and use it.
URL url = new URL(stringBuilder.toString());
InputStream stream = null;
try {
// Establish a connection
HttpURLConnection conn = (HttpURLConnection) url
.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
conn.addRequestProperty("Accept", "application/json"); conn.setDoInput(true);
conn.connect();
int responseCode = conn.getResponseCode();
Log.d(DEBUG_TAG, "The response code is: " + responseCode + " "
+ conn.getResponseMessage());
stream = conn.getInputStream();
return parseTopMovies(stringify(stream));
} finally {
if (stream != null) {
stream.close();
}
}
}
parsing been done here..
private ArrayList<HashMap<String, String>> parseTopMovies(String result) {
String streamAsString = result;
ArrayList<HashMap<String, String>> results = new ArrayList<HashMap<String, String>>();
try {
JSONObject jsonObject = new JSONObject(streamAsString);
JSONArray array = (JSONArray) jsonObject.get("results");
for (int i = 0; i < array.length(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
JSONObject jsonMovieObject = array.getJSONObject(i);
map.put(KEY_TITLE,
jsonMovieObject.getString("original_title"));
results.add(map);
}
} catch (JSONException e) {
System.err.println(e);
Log.d(DEBUG_TAG, "Error parsing JSON. String was: "
+ streamAsString);
}
return results;
}
public String stringify(InputStream stream) throws IOException,
UnsupportedEncodingException {
Reader reader = null;
reader = new InputStreamReader(stream, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(reader);
return bufferedReader.readLine();
}
}
@Override
protected void onPostExecute(Object result) {
update2((ArrayList<HashMap<String, String>>) result);
};
here i am displaying result
public void update2(ArrayList<HashMap<String, String>> result) {
ListView listView =(ListView)findViewById(R.id.container);
// Add results to listView.
adapter = new UpcomingMovieAdapters(this, R.layout.upcoming,result);
listView.setAdapter(adapter);
// Update Activity to show listView
//setContentView(listView);
}
Thanks in advance.
