Gente estou com esse código :
public class Inicial extends AppCompatActivity {
private ImageButton button,button2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_inicial);
button = (ImageButton)findViewById(R.id.imageButton8);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent it = new Intent(Inicial.this,MainActivity.class);
startActivity(it);
}
});Quando clicar no botão ele abre essa Class:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Praça XV - Araribóia"));
tabLayout.addTab(tabLayout.newTab().setText("Araribóia - Praça XV"));
tabLayout.addTab(tabLayout.newTab().setText("Tempo de viagem"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}}E tem esse PAGE ADAPTER
class PagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
TabFragment1 tab1 = new TabFragment1();
return tab1;
case 1:
TabFragment2 tab2 = new TabFragment2();
return tab2;
case 2:
TabFragment3 tab3 = new TabFragment3();
return tab3;
default:
return null;
}
}
@Override
public int getCount() {
return mNumOfTabs;
}
}Com todos os layouts e etc.
Agora eu quero colocar outro button pra abrir uma outra Activity com as mesmas 3 abas, mas com conteúdos diferentes.
Eu copiei e colei mas da CRASH no App.
Como eu posso fazer?
