I Am trying to create an actionbar without the app logo/text, and with a centralised picture, and i know it is possible with a custom view, here is my code:
this works great too! (read the bugreport comments ;))
actionBar.setLogo(new ColorDrawable(Color.TRANSPARENT));
I used this
ActionBar ab = getSupportActionBar();
ab.setDisplayShowHomeEnabled(true);
ab.setDisplayHomeAsUpEnabled(false);
ab.setHomeButtonEnabled(false);
ab.setLogo(null);
View homeIcon = findViewById(
Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.id.home : R.id.abs__home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
((View) homeIcon).setVisibility(View.GONE);
ab.setDisplayShowTitleEnabled(false);
Here's a simple workaround :
use the following in your onCreate method :
View homeIcon = findViewById(android.R.id.home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
this collapses the home button completely.
PS : i'm using standard ActionBar but this should work the same
Or
if you want to support in Sherlock Actionbar to than you have to use this
actionBar.setLogo(null); // forgot why this one but it helped
View homeIcon = findViewById(
Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.id.home : R.id.abs__home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
((View) homeIcon).setVisibility(View.GONE);
actionBar.setDisplayShowTitleEnabled(false);
It is worth noting that the selected answer will only work with the native ActionBar because the element android.R.id.home doesn't exist on pre-hc. That is, on pre-hc devices, you will get an NPE.
Since you are using ActionBarSherlock, I'm assuming you want to support pre-hc devices so you should use the correct id based on the platform version. ABS will expose the equivalent of android.R.id.home via R.id.abs__home for its implementation of the ActionBar.
So, we can tweak the suggested workaround as:
View homeIcon = findViewById(
Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.id.home : R.id.abs__home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
All post above collapsing the home icon but leaving a blank space. For avoiding that you need to set the logo size to zero . Below added my code snippet.it may help for others who struggle with same problem.thanks
actionBar.setLogo(new ColorDrawable(Color.TRANSPARENT));
View homeIcon = findViewById(
Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.id.home : R.id.abs__home);
((View) homeIcon.getParent()).setLayoutParams(new LinearLayout.LayoutParams(0, 0));
((View) homeIcon).setVisibility(View.GONE);
just remove DISPLAY_SHOW_HOME flag from your actionBar.setDisplayOptions() method.
