我试图实现上述设计。我可以更改图标,但无法更改底部文本。我正在使用材质底部导航栏
我通过为每个图标实现单独的选择器可绘制对象来实现图标更改。有什么方法可以让我对导航标题做同样的事情吗?
MainActivity.class
public class MainActivity extends AppCompatActivity {
BottomNavigationView navView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
navView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
R.id.navigation_home, R.id.navigation_saved, R.id.navigation_applied, R.id.navigation_profile, R.id.navigation_more)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(navView, navController);
}
