    <p>It's taken me some time to wrap my head around fragments, but this should be my last question on fragments, since I think I just about have them down. I know this is a huge mess of code to go through. But I'd appreciate the help, to make sure I'm not breaking any fundamental rules with fragments.</p> <p>I am going to post all of my code just to see if someone can "look over it" to see if I'm making any major mistakes or if I should go a simpler route. Lastly, as stated in the title, my fragment is NOT being replaced... it'd being added on top.</p> <p>File Tree:</p> <p><img src="https://i.stack.imgur.com/sxh3L.png" alt="enter image description here"></p> <p>MainActivity.java:</p> <pre><code>package com.example.learn.fragments; import android.app.Activity; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentTransaction; import android.view.LayoutInflater; import android.view.Menu; import android.view.View; import android.view.ViewGroup; public class MainActivity extends FragmentActivity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } /* Add a class to handle fragment */ public static class SSFFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View v = inflater.inflate(R.layout.choose_pill_frag, container, false); return v; } } public void red(View view) { // Create new fragment and transaction ExampleFragments newFragment = new ExampleFragments(); android.support.v4.app.FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); // Replace whatever is in the fragment_container view with this fragment, // and add the transaction to the back stack transaction.replace(R.id.frag, newFragment); transaction.addToBackStack(null); // Commit the transaction transaction.commit(); } public void blue(View view) { //Figure out code for "red" first } } </code></pre> <p>ExampleFragments.java:</p> <pre><code>package com.example.learn.fragments; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class ExampleFragments extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.red_pill_frag, container, false); } } </code></pre> <p>ActivityMain.xml:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;fragment android:id="@+id/frag" android:layout_width="match_parent" android:layout_height="match_parent" class="com.example.learn.fragments.MainActivity$SSFFragment" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>choose_pill_frag.xml</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;ImageButton android:id="@+id/imageButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:onClick="blue" android:src="@drawable/blue" /&gt; &lt;ImageButton android:id="@+id/imageButton2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:onClick="red" android:src="@drawable/red" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>red_pill_frag.xml</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:text="You stay in Wonderland and I show you how deep the rabbit-hole goes." android:textAppearance="?android:attr/textAppearanceLarge" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>The application should show two buttons. The two buttons exist in a single fragment, and then if you hit a button, the fragment gets replaced with a new fragment that shows the proper text. As of right now, it should replace, but it only seems to add it on top.</p>

    1. COI had the same problem, almost made me not want to use fragments any more, I had to remove the old fragment and then replace it for some stupid reason?

    3. CONo, you are not alone. Unless I really, really, really need a dynamic view, old fashioned activities are the way to go. I'm tempted to even write my own preferences activity with get and put shared preferences coded. Google made way to many preprep and postprep steps to the process. And why have an inflator. Stating that it's a fragment and just using a swap in or swap out function should be enough.

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).
