    volumeControl = (SeekBar) findViewById(R.id.volume_bar);
    year = (TextView)findViewById(R.id.year_level);
    volumeControl.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
            progressChanged = progress;
            year.setText(Integer.toString(progressChanged+7));
        }

Please help me.

Answer 1

If it doesn't concern you that the SearchView is collapsed at the start, try configuring the SearchView like this:

 android:showAsAction="collapseActionView|ifRoom"

This should make the actionbar show both, the SearchView and your Button. Plus the SearchView will only take up the remaining space to the left, when it gets expanded.

Answer 2

According to developer.android.com

If your app is using the Support Library for compatibility on versions as low as Android 2.1, the showAsAction attribute is not available from the android: namespace . Instead this attribute is provided by the Support Library and you must define your own XML namespace and use that namespace as the attribute prefix. (A custom XML namespace should be based on your app name, but it can be any name you want and is only accessible within the scope of the file in which you declare it.) For example:

res/menu/main_activity_actions.xml >>>>

   <menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <!-- Search, should appear as action button -->
    <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          yourapp:showAsAction="ifRoom"  />
    ...
 </menu>

Answer 3

A SearchView will default to taking up a majority of, if not all of the action bar in portrait mode. Try decreasing the size of the SearchView in menu.xml and see if the button is displayed.
