Question

I have this SQLite containing a number of ‘Projects’. Each ‘Project’ with its attributes from the SQLite Database Table are displayed in an activity. What I wanna do is, when a button inside the activity is clicked, it updates the C_FAVORITE row of that ‘Project’.

How am I able to do so? Which arguments do I need to put inside the update method below?

public void makeFavorite() {
Database.Project.C_FAVORITE.update(.......);
}

this is how I display the attributes of the Project on the activity:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.project);

        loader = new ImageLoader(this);
            Intent intent = getIntent();
            if (intent != null) {
                Uri uri = intent.getData();
                if (uri != null) {
                    final Cursor cursor = managedQuery(uri, new String[] {
                            BaseColumns._ID, Database.Project.C_PROJECTTITLE, Database.Project.C_ORGANIZATIONTITLE,
                            Database.Project.C_PROJECTDESCRIPTION,Database.Project.C_BIGIMAGE,Database.Project.C_DONATIONAMOUNT,Database.Project.C_ADDRESS,Database.Project.C_WEBSITE,Database.Project.C_SHORTCODE,Database.Project.C_KEYWORD,Database.Project.C_PRICE,Database.Project.C_CAMPAIGNID,Database.Project.C_PAYPALEMAIL,Database.Project.C_ELVAVAILABLE}, null, null, null);

                    if (cursor == null) {
                        finish();
                    } else {
                        if (cursor.moveToFirst()) {
                            ImageView img = (ImageView) findViewById(R.id.project_image);
                            TextView project_title = (TextView)findViewById(R.id.txt_project_title);
                               project_title.setText(cursor.getString(1));

Answer 1

You can try as follows:

public SQLiteDatabase sqd;

//Create connection of database

public void makeFavorite(String fieldname,String c_fav_value) {
ContentValues cv = new ContentValues();
cv.put(fieldname,c_fav_value);
int i= sqd.update(table_name, cv, where, where_clause);
}

If you have no where clause you can pass null there.
