Custom action bar does not fill parent

Question

Custom action bar does not fill parent.

I am using custom action bar for navigation drawer purpose. But My action bar keep some space left at left side of action bar.

I used code like this.

// to inflate custom view

            LayoutInflater inflator=   (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View v=inflator.inflate(R.layout.custom_action_top_bar, null);
            getActionBar().setHomeButtonEnabled(false);
            getActionBar().setDisplayShowTitleEnabled(false);
            getActionBar().setDisplayShowCustomEnabled(true);
            getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
            getActionBar().setCustomView(v);

            View v1 = getActionBar().getCustomView();
            LayoutParams lp = (LayoutParams) v1.getLayoutParams();
            lp.width = LayoutParams.FILL_PARENT;
            v1.setLayoutParams(lp);

how make action bar fill width

UPDATED ANSWER

remove android:layout_gravity="center" in root linear to be like this , make height wrap_content

<LinearLayout                 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:orientation="horizontal"
        android:weightSum="1.0" > 

      ......
</LinearLayout>

Prefer use getSupportActionBar() as default activity extends ActionBarActivity

import android.support.v7.app.ActionBar.LayoutParams;
import android.support.v7.widget.Toolbar;


public class MainActivity extends ActionBarActivity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


      getSupportActionBar().setHomeButtonEnabled(false);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().setDisplayShowCustomEnabled(true);
    getSupportActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));



    LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT,
            LayoutParams.MATCH_PARENT);
    getSupportActionBar().setCustomView(v, layoutParams);
    Toolbar parent = (Toolbar) v.getParent();
    parent.setContentInsetsAbsolute(0, 0);

}
}

Summary

I understand why you have a problem , you using eclipse with old support library that dosenot support ToolBar use appcompat-v21 or later

my advice to you , use Android studio as they stop support eclipse

this code working 100% , prove of concept
