How to put Array value to Database on dbSqlite?

My project used to save products information into shoppingCart on a database with dbSqlite. But, for now it should save information of product from server. According to web service, one variable type is List Array. It was String before. And one of them is double, it was String also. I changed real in dbSqlite but what I should do for Array? How can save it on dbSqlite again?
error: no suitable method found for put(String,List) method

You can read the array like this :
String[] myArray = `put your array here`
for (int i = 0; i < myArray.size(); i++)
{
//Here u insert the data by getting what u need from the array
data.put("Cost",myArray.get(i).Cost);
}

You should be fine serializing the list to string. I. e. you could serialize it to json and deserialize it if you need it again.
Here is a small code example for two functions you could use in your DatabaseHelper.
private String serialize(List<String) list) {
JSONArray jsonArray = new JSONArray();
for (String s : list) {
jsonArray.put(s);
}
return jsonArray.toString();
}
private List<String> deserialize(String json) {
JSONArray jsonArray = new JSONArray(json);
List<String> list = new ArrayList<>();
for (int i=0; i<jsonArray.getLength(); ++i) {
list.add(jsonArray.getString(i));
}
return list;
}
And then you can use these functions:
data.put("Image",serialize(Image));
List<String> image = deserialize(rs.getString(rs.getColumnIndexOrThrow("Image")));
(This is only pseudo-code. Maybe you need to adjust it. Furthermore the functions don't handle null-parameters and may throw NullPointerExceptions!)

How to get the real data text, with already substring text?

I'm doing create an Catalogue Movie app. I have a ListView which contains an ImageView, title, description, and release date.
In the ListView, I take a substring of the description, because it's too long if showed in a ListView, and now I want to get the real description, in the DetailActivity (setOnItemClickListener).
This is my code:
try {
String title = object.getString("title");
String description = object.getString("overview");
double movieRatet = object.getDouble("vote_average");
String movieRate = new DecimalFormat("#.#").format(movieRatet);
String releaseDate = object.getString("release_date");
String posterUrl = object.getString("poster_path");
posterUrl = POSTER_BASE_URL + "w185" + posterUrl;
description = description.length() > 64 ? description.substring(0,64)+"...":description;
Log.d("movie poster", posterUrl);
Log.d("movie title ", title);
Log.d("movie description ", description);
Log.d("movie release ", releaseDate);
this.title = title;
this.description = description;
this.rate = releaseDate;
this.imgurl = posterUrl;
}catch (Exception e){
e.printStackTrace();
}
This is my OnItemClickListener:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getApplicationContext(), "Clicked"+position,Toast.LENGTH_LONG).show();
RelativeLayout listItem = (RelativeLayout) view.findViewById(R.id.rl_item);
TextView clickedItemView = (TextView) listItem.findViewById(R.id.tv_judul);
TextView clickedItemView2 = (TextView) listItem.findViewById(R.id.tv_deskripsi);
TextView clickedItemView3 = (TextView) listItem.findViewById(R.id.tv_rate);
String title = clickedItemView.getText().toString();
String desk = clickedItemView2.getText().toString();
String rate = clickedItemView3.getText().toString();
Intent i = new Intent(getApplicationContext(), DetailActivity.class);
desk.substring(0);
i.putExtra("title", title);
i.putExtra("desk", desk);
i.putExtra("rate", rate);
startActivity(i);
}
});
Picture of the DetailActivity:
I want to get the full description, how?

you can add a params "fullMessage" to storage the all of the message,and "description" to storage some message.Then use i.putExtra("desk", fullMessage) to carry full message to another activity.
Another solution is to add those attribute to your TextView in ListView
<TextView
<!-- other value -->
android:maxLines="3"
android:ellipsize="end"/>
And you can put full message to this TextView,it will folding itself when the message is too long.

Just do not overwrite your description variable. Instead of above have one more variable that holds your truncated value, say overview.
String overview = description.length() > 64 ? description.substring(0,64)+"...":description;
Then your description variable will continue to hold the original value. Just use that where you need.

Try this :
mymodalclass:make class
public class MyModal {
String title ;
String description ;
double movieRatet ;
String movieRate;
String releaseDate;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public double getMovieRatet() {
return movieRatet;
}
public void setMovieRatet(double movieRatet) {
this.movieRatet = movieRatet;
}
public String getMovieRate() {
return movieRate;
}
public void setMovieRate(String movieRate) {
this.movieRate = movieRate;
}
public String getReleaseDate() {
return releaseDate;
}
public void setReleaseDate(String releaseDate) {
this.releaseDate = releaseDate;
}
public String getPosterUrl() {
return posterUrl;
}
public void setPosterUrl(String posterUrl) {
this.posterUrl = posterUrl;
}
String posterUrl ;
}
//****************************************
while parsing data :
Arraylist list = new ArrayList();
for(int i=0;i<yourjsonarray.length();i++){
JSONObject object = yourjsonarray.getJSONObject(i);
MyModal m = new MyModal();
m.setTitle(object.getString("title"));//like this set all data
//now add this object to list
list.add(m);
}
//now when you click list just get clicked position and by this position get that particular object and pass that to next activity
ex: position = your_clicked_position
MyModal clicked_modal_object = (MyModal) list.get(your_clicked_position);
//now pass this clicked_modal_object to next activity

You can use two variables.(I'm sure this is what #Gautam mentioned) The first is the full description and the second is the shorter description.
String description = object.getString("overview"); // full
String shortDesc = description.length() > 64 ? description.substring(0,64)+"...":description; // add this to listView
Log.d("movie description ", shortDesc);
I want to get the real description, in the DetailActivity
(setOnItemClickListener)
When button clicked, get the description string instead
i.putExtra("desk", description);
Note: Make sure you set description as globally.

getParcelableArrayExtra null pointer

I am using Parcelable for a custom Song object I have in my class. However, when ever I am trying to get an arraylist extra of type Song I always get a null pointer exception. I have no problem getting string extras from the intent but when I try to get this ArrayList I need I always get null. I am also getting a null when I just try to pass a Song object, so I am assuming there is some issue with it but I cannot figure it out for the life of me.
This is my song class
import android.os.Parcel;
import android.os.Parcelable;
public class Song implements Parcelable {
private String uri;
private String title;
private String artist;
private String album;
private String length;
private int count;
private int source;
public Song () {
}
public Song (String title, String artist, String album, String uri, String length, int count,
int source) {
this.uri = uri;
this.title = title;
this.artist = artist;
this.album = album;
this.length = length;
this.count = count;
this.source = source;
}
public String getUri() {
return uri;
}
public String getArtist() {
return artist;
}
public String getTitle() {
return title;
}
public String getLength() {
return length;
}
public int getCount() {return count;}
#Override
public String toString() {
return title + " - " +artist;
}
#Override
public boolean equals(Object o){
if (o instanceof Song) {
Song song = (Song) o;
if (title.equals(song.title) && length.equals(song.length)) {
return true;
}
}
return false;
}
public int compareTo(Song s) {
if (this.count < s.getCount()) {
return -1;
}
else if(this.count > s.getCount()){
return 1;
}
return 0;
}
public String getAlbum() {
return album;
}
public void setAlbum(String album) {
this.album = album;
}
public int getSource() {
return source;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.uri);
dest.writeString(this.title);
dest.writeString(this.artist);
dest.writeString(this.album);
dest.writeString(this.length);
dest.writeInt(this.count);
dest.writeInt(this.source);
}
protected Song(Parcel in) {
this.uri = in.readString();
this.title = in.readString();
this.artist = in.readString();
this.album = in.readString();
this.length = in.readString();
this.count = in.readInt();
this.source = in.readInt();
}
public static final Creator<Song> CREATOR = new Creator<Song>() {
#Override
public Song createFromParcel(Parcel source) {
return new Song(source);
}
#Override
public Song[] newArray(int size) {
return new Song[size];
}
};
}
This is the line I use to package the arraylist
Intent intent = new Intent();
Log.d("UTILS ", " size: " +queue.size()); // Making sure it is not null before passing
intent.setClass(context, PlayerService.class);
intent.putParcelableArrayListExtra(PlayerService.EXTRA_TRACK_LIST, queue);
context.startService(intent);
This is retrieving the arraylist in PlayerService class
public static final String EXTRA_TRACK_LIST = "EXTRA_TRACK_LIST";
private ArrayList<Song> trackList;
.
.
.
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent == null || intent.getAction() == null) {
Log.d(TAG, "unspecified command");
return START_STICKY;
}
trackList=intent.getParcelableArrayListExtra(PlayerService.EXTRA_TRACK_LIST);
if (trackList == null) {
Log.d("TRACKLIST", "IS NULL");
} else {
Log.d(TAG, "size: "+trackList.size());
}
.
.
.
// more irrelevant code

your parameter is wrong
public static final String EXTRA_TRACK_LIST = "EXTRA_TRACK_LIST";
so change like this
trackList = intent.getParcelableArrayListExtra(PlayerService.EXTRA_TRACK_LIST);

Is queue a Queue/List or similar? Or is it an array? If array, should be queue.length, right? From List to array try this. This should work.
intent.putParcelableArrayListExtra(PlayerService.EXTRA_TRACK_LIST, queue);
If not, let me know to keep trying. Also, you could also pass it as String. You could use GSON to convert it to JSON string. After converted to String, pass it as a single String.
Intent intent = new Intent(ActivityA.this, Service.class);
intent.putExtra(new Gson().toJson(queue), PlayerService.EXTRA_TRACK_LIST);
context.startService(intent);
And to retrieve that object again:
Song song = new Gson().fromJson(intent.getStringExtra(PlayerService.EXTRA_TRACK_LIST), Song.class);
Or, if list (I believe you case):
Type listType = new TypeToken<ArrayList<Song.class>>(){}.getType();
List<Song> songList = new Gson().fromJson(intent.getStringExtra(PlayerService.EXTRA_TRACK_LIST), listType);

How to addsong in User class using Playlist arrays?

addSong(title:String,filePath: String, artist:String):int
adds the song to the play list and returns 0 if added and –1 if the song can not be added because the list is full.
*** I keep on getting errors like method addsong(String, String, String) is not applicable for agrument int and also the getArtist method is not defined. How do I go upon it? Any suggestions or solutions to make it work?

Why won't my user-defined object construct?

I have an Parcelable object called Book and another called Author. I can't tell why the object constructor for Book is not working. The first bit of code is where i try to make it so I can send it to a parent activity. The values were checked before, and when I do the .toString() method on book, I get null Price: null
Activity Code
EditText editText = (EditText) findViewById(R.id.search_title);
String title = editText.getText().toString();
editText = (EditText) findViewById(R.id.search_author);
String author = editText.getText().toString();
editText = (EditText) findViewById(R.id.search_isbn);
int isbn = Integer.parseInt(editText.getText().toString());
...
Parcel p = Parcel.obtain();
p.writeInt(isbn);
p.writeString(title);
p.writeString(author);
p.writeString(editText.getText().toString());
p.writeString("$15.00");

Hi so I just gave up and made a new constructor that doesn't use Parcels.
But what was written below p.setDataPosition(0); may work as well for future users
