Adding a toolbar to a FragmentActivity

Question

Am extends a FragmentActivityin the classroom, which serves as my main activity, where my other activities spread. My problem is that I am expanding my other activities from my basic activity, I am losing the functionality of the toolbar. How can I add this to my base activity so that my actions can inherit the toolbar? Any pointers?

Answer 1

In case fragments should have a custom look ToolBar, you can implement ToolBarfor each fragment separately.

add ToolBarto fragment_layout:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"/>

find it in the fragment:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment, container, false);
        Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);

        //set toolbar appearance
        toolbar.setBackground(R.color.material_blue_grey_800);

        //for crate home button
        ActionBarActivity activity = (ActionBarActivity) getActivity();
        activity.setSupportActionBar(toolbar);
        activity.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

Menu listener

:

1.override onOptionsItemSelected :

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId()){
        case android.R.id.home:
            getActivity().onBackPressed();
    }
    return super.onOptionsItemSelected(item);
}

2.set listener onCreateView():

toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem menuItem) {
                return false;
            }
});

AppCompatActivity,

public class MainActivity extends AppCompatActivity { ...

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    FragmentTransaction ft = getSupportFragmentManager.beginTransaction();
    ....
    ....
