    <p>I have this nested view created from another activity. The values (texts to show, background color, etc) mainly are inputted by the user from the other activity. Here is the code on how I dynamically create the views:</p> <pre><code>@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); if (resultCode == RESULT_OK) { if (requestCode == 1) { // Create a New Linear Layout LinearLayout ll = new LinearLayout(this); ll.setOrientation(LinearLayout.VERTICAL); LinearLayout.LayoutParams llParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); float scale = getResources().getDisplayMetrics().density; //Set Bottom Margin float margin = 5; //RESIZE BOTTOM MARGIN HERE! int margs = (int) (margin * scale + 0.5f); //Set padding in dp float padding = 5; //RESIZE PADDING HERE! int pads = (int) (padding * scale + 0.5f); llParams.setMargins(0,0,0,margs); //Set Parameters for Android ll.setLayoutParams(llParams); ll.setPadding(pads, pads, pads, pads); //Set Background Color on Layout String chosenColor = data.getStringExtra("sendChosenColor"); if (chosenColor.equals("Green")){ ll.setBackgroundResource(R.color.HoloGreen); }else if (chosenColor.equals("Blue")){ ll.setBackgroundResource(R.color.HoloBlue); }else if (chosenColor.equals("Gray")){ ll.setBackgroundResource(R.color.HoloGray); }else if (chosenColor.equals("Orange")){ ll.setBackgroundResource(R.color.HoloOrange); }else { ll.setBackgroundResource(R.color.HoloYellow); } //Adding Layout to Appropriate Container int layoutCountLeft = subjectLeft.getChildCount(); int layoutCountRight = subjectRight.getChildCount(); if (layoutCountLeft &lt;= layoutCountRight){ subjectLeft.addView(ll); } else { subjectRight.addView(ll); } //Create TextView for SubjectName TextView SubjectName = new TextView(this); SubjectName.setText(data.getStringExtra("sendSubjectName")); SubjectName.setLayoutParams(new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); SubjectName.setTextSize(22); SubjectName.setTypeface(Typeface.DEFAULT_BOLD); //Create TextView for SubjectNumber TextView SubjectNumber = new TextView(this); SubjectNumber.setText(data.getStringExtra("sendSubjectNumb")); SubjectNumber.setLayoutParams(new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); SubjectNumber.setTextSize(16); //Creating the divider line ImageView divider = new ImageView(this); LinearLayout.LayoutParams dividerParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 2); divider.setLayoutParams(dividerParams); divider.setBackgroundResource(R.color.Black); //Add Views into the Layout ll.addView(SubjectNumber); ll.addView(SubjectName); ll.addView(divider); } } } </code></pre> <p>Can I save this without using databases?</p>

    1. COYou can do this with SharedPreferences. Check http://stackoverflow.com/questions/3624280/how-to-use-sharedpreferences-in-android-to-store-fetch-and-edit-values

    2. COSharedPrefs are used for key-value pairs, I think. How can I implement the Shared Prefs in saving nested views.

    3. COmaybe i misunderstood your question, but instead of save your view, you only save the values to create your view and recreate the view if needed?!

Guidance
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).
