POSaving dynamically added LinearLayouts without using savedInstanceState?

Body
copied!<p>I have a layout in which I have dynamically added custom views at a push of a button. These layouts extend LinearLayout and each carry their own unique Action objects.</p> <p>The views will disappear, however, if onCreate is called again, when the user navigates away or rotates the screen. I want to keep these custom ActionHolder views there. To add to the problem, the ActionHolder objects contain sensitive information. The Action objects themselves store a live timer(that is supposed to keep on ticking even if the app is off), as well as other information.</p> <p>According to an answer below, I have done the following, but to no avail. Here is what I have so far:</p> <pre><code>public class ActionHolder extends LinearLayout implements Serializable { /** * */ private static final long serialVersionUID = 2271402255369440088L; private Action action; private String timer; public static final int ACTION_TITLE = 0, ACTION_TIMER = 1, PAUSEANDPLAY_BTN = 2, FINISH_BTN = 3; public ActionHolder(Context context) { super(context); } public ActionHolder(Context context, AttributeSet attr) { super(context, attr); } public ActionHolder(Context context, AttributeSet attr, int defStyle) { super(context, attr, defStyle); } public void initiate(Action input) { // int hashedID = input.getActionName().hashCode(); // if (hashedID < 0) // hashedID *= -1; // this.setId(hashedID); this.setOrientation(LinearLayout.VERTICAL); this.setLayoutParams(new LinearLayout.LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); action = input; LayoutInflater inflater = LayoutInflater.from(getContext()); View view = inflater.inflate(R.layout.action_holder_layout, this, true); TextView actionTitle = (TextView) view .findViewById(com.tonimiko.mochi_bean.R.id.action_holder_title); actionTitle.setText(action.getActionName()); actionTitle.setId(ActionHolder.ACTION_TITLE); TextView actionTimer = (TextView) view .findViewById(R.id.action_holder_timer); actionTimer.setId(ActionHolder.ACTION_TIMER); Button pauseBtn = (Button) view .findViewById(com.tonimiko.mochi_bean.R.id.pause_and_play_timer_btn); pauseBtn.setId(ActionHolder.PAUSEANDPLAY_BTN); Button finishBtn = (Button) view .findViewById(com.tonimiko.mochi_bean.R.id.finish_activity_button); finishBtn.setId(ActionHolder.FINISH_BTN); action.setActivityStartTime(); } public Action finishAction() { action.setActivityStopTime(); return action; } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { super.onLayout(changed, l, t, r, b); } public String toString() { return "Action stored: " + action.getActionName(); } @Override public boolean equals(Object other) { ActionHolder otherObj = (ActionHolder) other; if (this.action.getActionName().toUpperCase() .equals(otherObj.action.getActionName().toUpperCase())) return true; return false; } @Override public int hashCode() { return action.getActionName().hashCode(); } @Override protected Parcelable onSaveInstanceState() { Parcelable superState = super.onSaveInstanceState(); Bundle data = new Bundle(); data.putString("Timer", timer); data.putSerializable("Action", action); Log.e("debug", "View onSaveInstanceState called!"); // TODO Parcelable test = new ActionHolderSavedState(superState, data); if(test==null) Log.e("debug", "NULL PARCELABLE"); // TODO return new ActionHolderSavedState(superState, data); } @Override protected void onRestoreInstanceState(Parcelable state) { Log.e("debug", "View onRestore called!"); if (state instanceof ActionHolderSavedState) { final ActionHolderSavedState savedState = (ActionHolderSavedState) state; this.action = savedState.getAction(); this.timer = savedState.getTimer(); // this.initiate(action); super.onRestoreInstanceState(savedState.getSuperState()); Log.e("debug", "View onRestoreInstanceState finished"); // TODO } } static class ActionHolderSavedState extends BaseSavedState { private Action storedAction; private String storedTimer; public ActionHolderSavedState(Parcelable superState, Bundle data) { super(superState); storedTimer = data.getString("Timer"); storedAction = (Action) data.getSerializable("Action"); } private ActionHolderSavedState(Parcel in) { super(in); storedTimer = in.readString(); storedAction = in.readParcelable(ActionHolder.class.getClassLoader()); } public Action getAction() { return storedAction; } public String getTimer() { return storedTimer; } @Override public void writeToParcel(final Parcel out, final int flags) { super.writeToParcel(out, flags); out.writeString(storedTimer); out.writeSerializable(storedAction); } // required field that makes Parcelables from a Parcel public static final Parcelable.Creator<ActionHolderSavedState> CREATOR = new Parcelable.Creator<ActionHolderSavedState>() { public ActionHolderSavedState createFromParcel(final Parcel in) { return new ActionHolderSavedState(in); } public ActionHolderSavedState[] newArray(int size) { return new ActionHolderSavedState[size]; } }; } } </code></pre> <p>Is there SOMETHING I am doing wrong? I've spend almost 4 days already on this.</p>
