    <p>I'm having a problem with adding elements in code. I want to add two buttons to a horizontal linear layout. My code works, but the second button partially covers the first button.</p> <p><strong>Question:</strong> How can I make it so that the second button doesn't cover the first button?</p> <p>This is the code:</p> <pre><code>public class MainActivity extends Activity { Button buttonFirst, buttonSecond; LinearLayout lau; LayoutParams params; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); buttonFirst = new Button(getApplicationContext()); buttonSecond = new Button(getApplicationContext()); lau = (LinearLayout) findViewById(R.id.layoutmadafaka); params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); lp.setMargins(-30, 0, 0, 0); buttonSecond.setLayoutParams(lp); buttonSecond.setBackgroundColor(Color.BLACK); lau.addView(buttonFirst,params); lau.addView(buttonSecond); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; } } </code></pre> <p>and 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" tools:context=".MainActivity" &gt; &lt;TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:text="@string/hello_world" /&gt; &lt;LinearLayout android:id="@+id/layoutmadafaka" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:orientation="horizontal" &gt; &lt;/LinearLayout&gt; &lt;/RelativeLayout&gt; </code></pre> <p>This must be done programmatically. When I use the bringToFront() method the buttons change positions but I don't want to do that. I want to first button on left side and second button next to first button.</p>

    1. COWhy do you need to create the Button in code? Can you declare it in the xml layout with `android:visibility="gone"` and then just switch it's visibility to visible in code when appropriate?

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.
