'How can I make the cardview's disappear?
When I click on any menu item present in the navigation drawer, the content of the menu item appears below the cards. The cards should disappear and then in their place the content of the menu items should be displayed. The contents of the menu items are written in the form of fragments. Could someone help me out in solving it? Attaching the code below...
Here is the MainActivity Java file
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close);
drawerLayout.setDrawerListener(actionBarDrawerToggle);
////////////////////////////////////////////////////////////////////
navigationView = (NavigationView)findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
switch (menuItem.getItemId())
{
case R.id.menu_profile:
fragmentTransaction=getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.main_container, new ProfileFragment());
fragmentTransaction.commit();
getSupportActionBar().setTitle("Profile");
menuItem.setChecked(true);
drawerLayout.closeDrawers();
break;
case R.id.menu_language:
fragmentTransaction=getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.main_container, new LanguageFragment());
fragmentTransaction.commit();
getSupportActionBar().setTitle("Set Language");
menuItem.setChecked(true);
drawerLayout.closeDrawers();
break;
case R.id.menu_tutorial:
fragmentTransaction=getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.main_container, new TutorialFragment());
fragmentTransaction.commit();
getSupportActionBar().setTitle("Tutorial");
menuItem.setChecked(true);
drawerLayout.closeDrawers();
break;
}
return true;
}
});
}

Solution 1:[1]
Every Android View has an ability to appear and disappear. Just use the setVisibility() in your java code and set it to View.GONE
Example:
CardView cardView1 = findViewById(R.id.card_pest);
cardView1.setVisibility(View.GONE)
Solution 2:[2]
val cardView = findViewById<CardView>(R.id.cardview2)
val destroyer = findViewById<ImageView>(R.id.imageView8)
destroyer.setOnClickListener {
cardView.visibility = View.GONE
}
