Start activity without ActionBar and add it in the onCreate event

Question

I'm using the AppCompat/ActionBarCompat library and I need to create a custom ActionBar. I need to open the activity without an ActionBar and enable it only when I add the custom view. How can I do this?

PS: I need to define the activity to not use an ActionBar through the AndroidManifest.xml and my application minimum API level is 10.

Answer 1

.hide() the action bar and then .show() the action bar when your ready for it

import android.support.v7.app.ActionBar;

...

private ActionBar mActionbar;

...

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mActionbar = getSupportActionBar();
    mActionbar.hide()
}

... somewhere when something cool happens

mActionbar.show();
