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
You can insert this code in your xml file
<androidx.appcompat.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimaryDark"
android:elevation="4dp"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Toolbar Title"
android:textColor="#000000"
android:textSize="20dp"
android:id="@+id/toolbar_title" />
</androidx.appcompat.widget.Toolbar>
Setting android:gravity="center"
worked for me
No styling nothing. Toolbar is basically a ViewGroup
all you need to do is set gravity of elements in it.
<android.support.v7.widget.Toolbar
android:id="@+id/htab_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="top"
android:background="@color/partial_transparent"
android:gravity="center"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
A very quick and easy way to set a custom font is to use a custom titleTextAppearance
with a fontFamily
:
Add to styles.xml:
<style name="ToolbarTitle" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">16sp</item>
<item name="android:textColor">#FF202230</item>
<item name="android:fontFamily">@font/varela_round_regular</item>
</style>
In your res folder create a font folder (Ex: varela_round_regular.ttf)
Read the official guide to find out more https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml.html
Solution that I used for this problem:
public static void applyFontForToolbarTitle(Activity a){
Toolbar toolbar = (Toolbar) a.findViewById(R.id.app_bar);
for(int i = 0; i < toolbar.getChildCount(); i++){
View view = toolbar.getChildAt(i);
if(view instanceof TextView){
TextView tv = (TextView) view;
if(tv.getText().equals(a.getTitle())){
tv.setTypeface(getRuneTypefaceBold(a));
break;
}
}
}
}
For center gravity I think it would be necessary to change layout params to match_parent horizontally and then:
tv.setGravity(Gravity.CENTER);
private void makeTitleCenter(String title, Toolbar toolbar) {
if (title != null && !TextUtils.isEmpty(title.trim())) {
final String tag = " ";
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle(tag);
}
TextView titleTv = null;
View leftBtn = null;
for (int i = 0; i < toolbar.getChildCount(); i++) {
View view = toolbar.getChildAt(i);
CharSequence text = null;
if (view instanceof TextView && (text = ((TextView) view).getText()) != null && text.equals(tag)) {
titleTv = (TextView) view;
} else if (view instanceof ImageButton) {
leftBtn = view;
}
}
if (titleTv != null) {
final TextView fTitleTv = titleTv;
final View fLeftBtn = leftBtn;
fTitleTv.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
fTitleTv.getViewTreeObserver().removeOnGlobalLayoutListener(this);
int leftWidgetWidth = fLeftBtn != null ? fLeftBtn.getWidth() : 0;
fTitleTv.setPadding(DimenUtil.getResources().getDisplayMetrics().widthPixels / 2 - leftWidgetWidth - fTitleTv.getWidth() / 2, 0, 0, 0);
fTitleTv.requestLayout();
}
});
}
}
}
for custom font in toolbar you can override textView font in style and then every textView in your app also toolbar title font changed automatically i tested it in android studio 3.1.3
in style do it:
<style name="defaultTextViewStyle" parent="android:Widget.TextView">
<item name="android:fontFamily">@font/your_custom_font</item>
</style>
and then in your theme use this:
<item name="android:textViewStyle">@style/defaultTextViewStyle</item>
