    <blockquote> <p>...it will display the new value if I turn my phone and orientation changes</p> </blockquote> <p>Android will destroy and re-create the activity when run-time configuration changes occur. It makes sense that your new variables are being drawn on screen rotation, because the entire activity is re-created:</p> <p><a href="http://developer.android.com/guide/topics/resources/runtime-changes.html" rel="nofollow">http://developer.android.com/guide/topics/resources/runtime-changes.html</a></p> <p>If most of your TextView widgets are updating when your PlayScreenActivity is resumed, your refreshDisplay() call is working (to a degree). Which widget doesn't redraw? I'd also throw in some logging and watch the LogCat like zapl suggested.</p> <p><strong>EDIT</strong></p> <p>Sample code with some logging (I moved the widgets into fields...)</p> <pre><code>public class PlayscreenActivity extends Activity { Data data_; String TAG = "PlayScreenActivity"; TextView lemonsLeftTextLabel; TextView sugarLeftTextLabel; TextView iceLeftLabel; TextView cupsLeftTextLabel; TextView totalCashTextLabel; Button shopButton; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d(TAG, "Creating PlayScreen activity..."); setContentView(R.layout.main); Log.d(TAG, "Assigning buttons..."); lemonsLeftTextLabel = (TextView) findViewById(R.id.lemonsLeftText); sugarLeftTextLabel = (TextView) findViewById(R.id.sugarLeftText); iceLeftLabel = (TextView) findViewById(R.id.iceLeftText); cupsLeftTextLabel = (TextView) findViewById(R.id.cupsLeftText); totalCashTextLabel = (TextView) findViewById(R.id.totalCashText); shopButton = (Button) findViewById(R.id.btnshop); lemonsLeftTextLabel.setText("Lemons: "); sugarLeftTextLabel.setText("Sugar: "); iceLeftLabel.setText("Ice: "); cupsLeftTextLabel.setText("Cups: "); shopButton.setOnClickListener(new SupplyShopListener()); Log.d(TAG, "onCreate() complete"); } private class SupplyShopListener implements View.OnClickListener { public void onClick(View v){ //Intent i = new Intent(v.getContext(), SupplyShopActivity.class); //startActivity(i); refreshDisplay(); } } @Override public void onResume(){ Log.d(TAG, "onResume() called"); super.onResume(); data_ = getData(); Log.d(TAG, "Data fetched"); Log.d(TAG, "Contents of data = " + "Lemons: " + Integer.toString(data_.lemons_) + " | " + "Sugar: " + Integer.toString(data_.sugar_) + " | " + "Ice: " + Integer.toString(data_.ice_) + " | " + "Cups: " + Integer.toString(data_.cups_) + " | " + "Cash: " + data_.cash_ + " | "); refreshDisplay(); } @Override public void onPause(){ Log.d(TAG, "onPause() called"); super.onPause(); saveData(); refreshDisplay(); } @Override public void onConfigurationChanged(Configuration newConfig){ Log.d(TAG, "onConfigurationChanged() called"); super.onConfigurationChanged(newConfig); } private Data getData() { Log.d(TAG, "getData() called - restoring"); GameData player_data = new GameData(this); player_data.open(); Log.d(TAG, "Pulling data from game string..."); Data game_state = new Data(player_data.getGameString()); player_data.close(); Log.d(TAG, "Contents of data = " + "Lemons: " + Integer.toString(game_state.lemons_) + " | " + "Sugar: " + Integer.toString(game_state.sugar_) + " | " + "Ice: " + Integer.toString(game_state.ice_) + " | " + "Cups: " + Integer.toString(game_state.cups_) + " | " + "Cash: " + game_state.cash_ + " | "); return game_state; } private void saveData() { Log.d(TAG, "saveData() called - saving"); GameData player_data = new GameData(this); player_data.open(); Log.d(TAG, "Serializing data into GameData object"); Log.d(TAG, "Contents of data = " + "Lemons: " + Integer.toString(data_.lemons_) + " | " + "Sugar: " + Integer.toString(data_.sugar_) + " | " + "Ice: " + Integer.toString(data_.ice_) + " | " + "Cups: " + Integer.toString(data_.cups_) + " | " + "Cash: " + data_.cash_ + " | "); player_data.setGameString(data_.SerializeGame()); player_data.close(); } private void refreshDisplay() { Log.d(TAG, "refreshDisplay() called - redrawing UI"); NumberFormat nf = NumberFormat.getInstance(); nf.setMinimumFractionDigits(2); nf.setMaximumFractionDigits(2); String totalCash = nf.format(data_.cash_); lemonsLeftTextLabel.setText("Lemons: " + Integer.toString(data_.lemons_)); sugarLeftTextLabel.setText("Sugar: " + Integer.toString(data_.sugar_)); iceLeftLabel.setText("Ice: " + Integer.toString(data_.ice_)); cupsLeftTextLabel.setText("Cups: " + Integer.toString(data_.cups_)); totalCashTextLabel.setText("Cups: " + totalCash); } } </code></pre>

COWell I ran the catlog for Sugar and I pu a log in both the shop activity and the playscreen. when I click the button to buy sugar I have a refreshTotal in that activity that shows total purchased amount before I accept and go back to playscreen.

    3. COWell, I'm not sure about the Data and GameData objects, but you're choosing to create a new GameData object in saveData(), and then you're passing it the entire activity, which seems a bit excessive. If you only want to persist the data, try passing a Bundle instead? Also, you could try using onRetainNonConfigurationInstance() to actually persist a full object. Doesn't really persist it beyond memory, but it might be a useful alternative? http://android-developers.blogspot.ca/2009/02/faster-screen-orientation-change.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
