Add back button to action bar

android, android-actionbar, android-layout

Solution

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);
    }
}

Problem

I have been trying to add a back button to the action bar. 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?
