    <p>As a an inexperienced Android programmer I need some help. I'm designing this app for a church that needs an Activity that can record prayer requests (similar to making a to-do list). At this point I can type items into a list, but they don't seem to save and come back after closing using the Shared Preferences excerpt from below, also looking around this site it looks like I can do this without a physical button to press to save.</p> <p>SharedPreferences prayerRequests = getPreferences(Activity.MODE_PRIVATE);</p> <pre><code>ListView myListViewa = (ListView)findViewById(R.id.myListView); SharedPreferences.Editor editor = prayerRequests.edit(); editor.putString("prayers", myListViewa.toString()); editor.apply(); </code></pre> <p>The entire class is here:</p> <pre><code> package com.direction.investor.prayerjournal; import java.util.ArrayList; import android.annotation.TargetApi; import android.app.Activity; import android.os.Build; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.widget.ArrayAdapter; import android.widget.EditText; import android.widget.ListView; import android.widget.TextView; import android.content.SharedPreferences; import android.content.SharedPreferences.Editor; public class prayerRequests extends Activity { @TargetApi(Build.VERSION_CODES.GINGERBREAD) public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.prayerrequest); ListView myListView = (ListView)findViewById(R.id.myListView); final EditText myEditText = (EditText)findViewById(R.id.myEditText); final ArrayList&lt;String&gt; prayers = new ArrayList&lt;String&gt; (); final ArrayAdapter&lt;String&gt; aa; aa = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, prayers); myListView.setAdapter(aa); SharedPreferences prayerRequests = getPreferences(Activity.MODE_PRIVATE); ListView myListViewa = (ListView)findViewById(R.id.myListView); SharedPreferences.Editor editor = prayerRequests.edit(); editor.putString("prayers", myListViewa.toString()); editor.apply(); myEditText.setOnKeyListener(new View.OnKeyListener() { public boolean onKey(View v, int keyCode, KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_DOWN) if ((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) || (keyCode == KeyEvent.KEYCODE_ENTER)) { prayers.add(0, myEditText.getText().toString()); aa.notifyDataSetChanged(); myEditText.setText(""); return true; } return false; } }); } } </code></pre>

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.
