Android Studio syntax errors

Question

I just started to learn about Android App Development, and I am about to create a simple application for starter right now.

I followed a tutorial on YouTube, but I don't know why I get some errors when I'm trying to run my app. It says they expect a ;, ), and more. I tried to look into my code, and i've made sure that every ( have ), and every line has ;

But the list expands and I don't know what's actually wrong.

package org.kosmik.infokosmik;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
import android.widget.FrameLayout;
public class MainActivity extends AppCompatActivity {
private BottomNavigationView mMenuUtama;
private FrameLayout mFrameUtama;
private berandaFragment berandaFragment;
private beritaFragment beritaFragment;
private radioFragment radioFragment;
private kegiatanFragment kegiatanFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 mFrameUtama = (FrameLayout) findViewById(R.id.frame_utama);
 mMenuUtama = (BottomNavigationView) findViewById((R.id.menu));
 berandaFragment = new berandaFragment();
 beritaFragment = new beritaFragment();
 radioFragment = new radioFragment();
 kegiatanFragment = new kegiatanFragment();
 mMenuUtama.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
 @Override
 public boolean onNavigationItemSelected(@NonNull MenuItem item) {
 switch (item.getItemId())) {
 case R.id.menu_beranda :
 setFragment(berandaFragment);
 return true;
 case R.id.menu_berita :
 setFragment(beritaFragment);
 return true;
 case R.id.menu_radio :
 setFragment(radioFragment);
 return true;
 case R.id.menu_kegiatan :
 setFragment(kegiatanFragment);
 return true;
 default:
 return false;
 }
 }
 }
}
public void setFragment(Fragment fragment) {
 FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
 fragmentTransaction.replace(R.id.frame_utama, fragment);
 fragmentTransaction.commit();
};}

This is my code on MainActivity.java . Anyway, i would really appreciate it if you would answer and explain it.

• Michael Dodd: Need to remove an extra closing bracket from switch (item.getItemId())). Your brackets should always match up.
• CodeChimp: Android Studio should highlight where missing ; are in red, look down the right hand side scrollbar and you will see a red indicator.
• Michael Dodd: You also only need one set of brackets for findViewById((R.id.menu))
• Michael Dodd: Finally, you don't need the ; at the end of the setFragment function.
• Christopher: And it looks like a closing bracket ) needs to be added after (new BottomNavigationView.OnNavigationItemSelectedListener(), before the opening curly brace {. It would help if you included the error message(s) that you are getting.

Answer 1

Dear You started a method parenthesis named setOnNavigationItemSelectedListener but never closed, please close the method parenthesis as below:

default:
 return false;
 }
 }
 });
}
public void setFragment(Fragment fragment) {
 FragmentTransaction fragmentTransaction = 
 getSupportFragmentManager().beginTransaction();
 fragmentTransaction.replace(R.id.frame_utama, fragment);
 fragmentTransaction.commit();
}

• Dasharath Singh Bajroliya: also need to remove extra parenthesis from switch (item.getItemId())) ... should be like as switch (item.getItemId())
• Yahya98: Thank you very much for the help. I thought i have checked all the parenthesis, seems i need to be more careful.
