Android toolbar center title and custom font

Question

I\'m trying to figure out the right way to use a custom font for the toolbar title, and center it in the toolbar (client requirement).

At the moment, i\'m using the

Answer 1

I don't know if anything changed in the appcompat library but it's fairly trivial, no need for reflection.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

// loop through all toolbar children right after setting support 
// action bar because the text view has no id assigned

// also make sure that the activity has some title here
// because calling setText() with an empty string actually
// removes the text view from the toolbar

TextView toolbarTitle = null;
for (int i = 0; i < toolbar.getChildCount(); ++i) {
    View child = toolbar.getChildAt(i);

    // assuming that the title is the first instance of TextView
    // you can also check if the title string matches
    if (child instanceof TextView) {
        toolbarTitle = (TextView)child;
        break;
    }
}

I was facing the same issue, fixed by doing this in MainActivity

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);

And In Fragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    if (view == null) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_example, container, false);
        init();
    }
    getActivity().setTitle("Choose Fragment");
    return view;
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.example_menu, menu);
}

I found another way to add custom toolbar without any adicional Java/Kotlin code.

• First: create a XML with your custom toolbar layout with AppBarLayout as the parent:

  <?xml version="1.0" encoding="utf-8"?>
  <android.support.design.widget.AppBarLayout                     
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:theme="@style/AppTheme.AppBarOverlay">
  
  <android.support.v7.widget.Toolbar
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="?attr/actionBarSize"
      android:background="?attr/colorPrimary"
      app:popupTheme="@style/AppTheme.PopupOverlay">
  
      <ImageView
          android:layout_width="80dp"
          android:layout_height="wrap_content"
          android:layout_gravity="right"
          android:layout_marginEnd="@dimen/magin_default"
          android:src="@drawable/logo" />
  
  </android.support.v7.widget.Toolbar>
  

• Second: Include the toolbar in your layout:

  <?xml version="1.0" encoding="utf-8"?>                
  <android.support.constraint.ConstraintLayout 
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@color/blue"
      tools:context=".app.MainAcitivity"
      tools:layout_editor_absoluteY="81dp">
  
      <include
          layout="@layout/toolbar_inicio"
          app:layout_constraintEnd_toEndOf="parent"
          app:layout_constraintStart_toStartOf="parent"
          app:layout_constraintTop_toTopOf="parent" />
  
      <!-- Put your layout here -->
  
  </android.support.constraint.ConstraintLayout>

To use a custom title in your Toolbar all you need to do is remember is that Toolbar is just a fancy ViewGroup so you can add a custom title like so:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_top"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="@color/action_bar_bkgnd"
    app:theme="@style/ToolBarTheme" >


     <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Toolbar Title"
        android:layout_gravity="center"
        android:id="@+id/toolbar_title" />


    </android.support.v7.widget.Toolbar>

This means that you can style the TextView however you would like because it's just a regular TextView. So in your activity you can access the title like so:

Toolbar toolbarTop = (Toolbar) findViewById(R.id.toolbar_top);
TextView mTitle = (TextView) toolbarTop.findViewById(R.id.toolbar_title);

Answer 5

No one has mentioned this, but there are some attributes for Toolbar:

app:titleTextColor for setting the title text color

app:titleTextAppearance for setting the title text appearance

app:titleMargin for setting the margin

And there are other specific-side margins such as marginStart, etc.

Answer 6

I solved this solution , And this is a following codes:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Order History"
            android:layout_gravity="center"
            android:id="@+id/toolbar_title"
            android:textSize="17sp"
            android:textStyle="bold"
            android:textColor="@color/colorWhite"
            />

    </android.support.v7.widget.Toolbar>

And you can change title/label , in Activity, write a below codes:

Toolbar toolbarTop = (Toolbar) findViewById(R.id.toolbar_top);

TextView mTitle = (TextView) toolbarTop.findViewById(R.id.toolbar_title); mTitle.setText("@string/....");
