}

dialog fragment xml:

<linearlayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="wrap_content"     android:layout_height="match_parent"     android:orientation="vertical">     <textview         android:id="@+id/textview1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:layout_margin="20dp"         android:text="Выберите дополнительный предмет:"         android:textappearance="?android:attr/textappearancelarge">     </textview>      <tablelayout         android:layout_width="match_parent"         android:layout_height="wrap_content">          <button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/inf"             android:id="@+id/btn_inf" />          <button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/phys"             android:id="@+id/btn_phys" />          <button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/soc"             android:id="@+id/btn_soc" />          <button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/chem"             android:id="@+id/btn_chem" />          <button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/biol"             android:id="@+id/btn_biol" />     </tablelayout>  </linearlayout> 

try spinner position:

super.getactivity().addcontentview(textview, lp);  lp.addrule(relativelayout.align_parent_bottom); super.getactivity().addcontentview(spinner, lp);
