android toolbar 假标题居中

<android.support.v7.widget.Toolbar    android:id="@+id/toolbar_top"    android:layout_height="wrap_content"    android:layout_width="match_parent"    android:minHeight="?attr/actionBarSize">    <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);

If anyone else can’t remove the default app name title, do this:

1、Call setSupportActionBar(yourToolbar) 
2、CallgetSupportActionBar().setDisplayShowTitleEnabled(false);`
