I want my view to look like this:

I want to add the back button in the left of the action bar.

I added this code

ActionBar actionBar = getActionBar();  actionBar.setDisplayHomeAsUpEnabled(true); 

but it doesn't work.

How can I fix this?

Answer 1

After setting actionBar.setHomeButtonEnabled(true);

Add the following code:

@Override public boolean onOptionsItemSelected(MenuItem item) {     switch (item.getItemId()) {         case android.R.id.home:             // app icon in action bar clicked; goto parent activity.             this.finish();             return true;         default:             return super.onOptionsItemSelected(item);     } }
