Retrieve method: ``` public void retrievedb() { strquery = "SELECT * FROM api_settings"; Cursor mCursor = (MainscreenActivity.JEEMAAndroSMSDB).rawQuery( strquery, null); if (mCursor.getCount() != 0) { mCursor.moveToLast(); for (int i = mCursor.getCount() - 1; i >= 0; i--) { dbid = mCursor.getString(0); dbapiname = mCursor.getString(1); dbURL = mCursor.getString(2); dbUnameVar = mCursor.getString(3); dbUnameVal = mCursor.getString(4); dbPwdVar = mCursor.getString(5); dbPwdVal = mCursor.getString(6); dbsendername = mCursor.getString(7); dbdestinationvar = mCursor.getString(8); dbmsgvariable = mCursor.getString(9); dbchars = mCursor.getString(10); } } if ((dbapiname == null) || (dbURL == null) || (dbUnameVar == null) || (dbUnameVal == null) || (dbPwdVar == null) || (dbPwdVal == null) || (dbsendername == null) || (dbdestinationvar == null) || (dbmsgvariable == null) || (dbchars == null)) { tvText = (TextView) findViewById(android.R.id.text1); tvText.setVisibility(1); } else { adapter = new ArrayAdapter<Settingsmodel>(this, android.R.layout.simple_list_item_1, listItems); tvText = (TextView) findViewById(android.R.id.text1); tvText.setVisibility(View.GONE); strquery = "SELECT ID,API_Name FROM api_settings"; mCursor = (MainscreenActivity.JEEMAAndroSMSDB).rawQuery(strquery, null); if (mCursor.getCount() != 0) { mCursor.moveToFirst(); do { dbid = mCursor.getString(0); dbapiname = mCursor.getString(1); listItems.add(new Settingsmodel(dbapiname, dbid)); adapter.notifyDataSetChanged(); } while (mCursor.moveToNext()); } } } ``` Context Menu: ``` @Override public void onCreateContextMenu(ContextMenu menu, final View v, ContextMenuInfo menuInfo) { if (v.getId() == android.R.id.list) { AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo; Settingsmodel selectedValue = (Settingsmodel) getListAdapter() .getItem(info.position); String tempo = selectedValue.getSpinnerText(); menu.setHeaderTitle(tempo); String[] menuItems = getResources().getStringArray(R.array.menu); for (int i = 0; i < menuItems.length; i++) { menu.add(Menu.NONE, i, i, menuItems[i]); } } } @Override public boolean onContextItemSelected(MenuItem item) { AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item .getMenuInfo(); int menuItemIndex = item.getItemId(); String[] menuItems = getResources().getStringArray(R.array.menu); String menuItemName = menuItems[menuItemIndex]; Settingsmodel selectedValue = (Settingsmodel) getListAdapter().getItem( info.position); String temp0 = selectedValue.getSpinnerText(); String temp1 = selectedValue.getValue(); int id = Integer.parseInt(temp1); if (menuItemName.equalsIgnoreCase("Set as Default")) { ContentValues values = new ContentValues(); values.put(MainscreenActivity.COL_Set_Default, value); MainscreenActivity.JEEMAAndroSMSDB.update( MainscreenActivity.TABLE_Name, values, "ID=" + id, null); values.put(MainscreenActivity.COL_Set_Default, 0); Toast.makeText(getBaseContext(), temp0 + " is set as Default", Toast.LENGTH_LONG).show(); MainscreenActivity.JEEMAAndroSMSDB.update( MainscreenActivity.TABLE_Name, values, "ID!=" + id, null); } if (menuItemName.equalsIgnoreCase("Delete")) { MainscreenActivity.JEEMAAndroSMSDB.delete( MainscreenActivity.TABLE_Name, "ID=" + id, null); Toast.makeText(getBaseContext(), "API Deleted Successfully", Toast.LENGTH_SHORT).show(); retrievedb(); } return true; } ```
