I have created an activity to hold fragments. There is no up button displayed in the toolbar when it is run or in the xml preview.
This is the code I used to add the toolbar to the activity
Toolbar mToolbar = (Toolbar) findViewById(R.id.category_toolbar);
setSupportActionBar(mToolbar);
if(getSupportActionBar() != null){
getSupportActionBar().setTitle("Test");
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
I've used all the correct libraries (AppCompatActivity). This Activity holds a fragment and thats were it doesn't show.
XML for the activity
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="@+id/category_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/toolbar">
</android.support.v7.widget.Toolbar>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/fragment_container">
</LinearLayout>
</LinearLayout>
I've also set the parent activity in the manifest file
<activity android:name=".TestActivity"
android:parentActivityName=".MainActivity">
</activity>
Is there anything else I need to add to make it work?
Thanks
Since you are using AppCompatActivity
as base activity, using setDisplayHomeAsUpEnabled(true)
rather than setDefaultDisplayHomeAsUpEnabled(true)
, would resolve your problem.
setDefaultDisplayHomeAsUpEnabled(true)
would work if you use ActionBarActivity.
