从操作栏中删除后退箭头按钮

Question

In my Android Project, whenever I go from First Activity to Second, I get an left arrow button followed by the some text in the action bar. That left arrow only comes when I set my First Activity as the hierarchical parent of the Second Activity.

I want to remove that back button and replace it with an icon. I have read other posts for the same question, and so I have already tried the following code in my onCreate() method.

getActionBar().setDisplayHomeAsUpEnabled(false);

But after reaching to the second activity, the app gets crashed.

Please help me out.

Answer 1

Use getSupportActionBar() bar:

getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(false);

Answer 2

getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);
