    copied!<p>I am trying to display information from a database as checkboxes. Right now it works fine, but places one column of checkboxes on the screen. What I want to do is have it split into 2.</p> <p><strong>What it Does Now:</strong><br> item1<br> item2<br> item3<br> item4<br> item5</p> <p><strong>What I Want:</strong><br> item1 item2<br> item3 item4<br> item5</p> <p>Preferably the new 2 column list would be evenly sized, each getting 50% of the screen, even if the text assigned is different lengths. </p> <p>I have searched a lot, and tried like 3 different things. Havn't found anything that works. Below is my code as it is (creating one column). </p> <pre><code>private void listStudents() { st = (LinearLayout)findViewById(R.id.studTable); ml = (RelativeLayout)findViewById(R.id.main); ArrayList&lt;ArrayList&lt;String&gt;&gt; studentlst = new ArrayList&lt;ArrayList&lt;String&gt;&gt;(); studentlst = db.getAllStudentsRowsAsArrays(); final int sllen = studentlst.size(); final String student[][] = new String[sllen][3]; CheckBox cb[] = new CheckBox[sllen]; TextView pemail[] = new TextView[sllen]; int num = st.getChildCount(); if(num != 0) st.removeAllViews(); String tsl = sllen + ""; nos.setText(tsl); for(int x=0; x &lt; sllen; x++) { /************************ * student[x][case] * * case options * * 0 = id * * 1 = name * * 2 = email * ************************/ String curstudent = studentlst.get(x).toString(); student[x][0] = curstudent.substring(1,curstudent.indexOf(",")); student[x][1] = curstudent.substring(curstudent.indexOf(" ")+1,curstudent.lastIndexOf(",")); student[x][2] = curstudent.substring(curstudent.lastIndexOf(" ")+1, curstudent.length() - 1); } Arrays.sort(student, new Comparator&lt;String[]&gt;() { @Override public int compare(String[] entry1, String[] entry2) { String name1 = entry1[1]; String name2 = entry2[1]; return name1.compareTo(name2); } }); for(int x=0;x&lt;sllen;x++) { cb[x] = new CheckBox(this); cb[x].setId(x+100); cb[x].setText(student[x][1]); pemail[x] = new TextView(this); pemail[x].setText(student[x][2]); pemail[x].setId(x+1000); pemail[x].setVisibility(View.INVISIBLE); st.addView(cb[x],x); ml.addView(pemail[x],x); } } </code></pre> <p>XML File</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;TextView android:id="@+id/lblmainselclass" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="82dp" android:layout_marginTop="7dp" android:text="@string/lblmainselectclass" /&gt; &lt;Spinner android:id="@+id/mainclassspinner" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/lblmainselclass" /&gt; &lt;ScrollView android:id="@+id/scrollView1" android:layout_width="wrap_content" android:layout_height="250dp" android:layout_below="@+id/lblmainselstudents" android:layout_centerHorizontal="true" &gt; &lt;LinearLayout android:id="@+id/studTable" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" &gt; &lt;/LinearLayout&gt; &lt;/ScrollView&gt; &lt;TextView android:id="@+id/lblmainselstudents" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/mainclassspinner" android:layout_centerHorizontal="true" android:layout_marginTop="5dp" android:text="@string/lblselectstud" /&gt; &lt;Button android:id="@+id/btnsend" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:text="@string/btnlblsend" /&gt; &lt;Spinner android:id="@+id/mainresponsespinner" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/btnsend" android:layout_centerHorizontal="true" android:layout_marginBottom="30dp" /&gt; &lt;TextView android:id="@+id/mainnumofstudents" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:text="@string/invis" android:visibility="invisible" /&gt; &lt;TextView android:id="@+id/classselected" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/invis" android:visibility="invisible" /&gt; &lt;TextView android:id="@+id/responseselected" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/invis" android:visibility="invisible" /&gt; &lt;TextView android:id="@+id/numchecked" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/invis" android:visibility="invisible" /&gt; </code></pre> <p></p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
