I'm getting an error when I'm running my project. I was just following this tutorial and used it in my project.
my code which is exactly alike in the tutorial
public class MainEventActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_event_activity);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new OneFragment(), "ONE");
adapter.addFragment(new TwoFragment(), "TWO");
adapter.addFragment(new ThreeFragment(), "THREE");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
Im calling the MainEventActivity like this :
btnNext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(MainActivity.this, MainEventActivity.class);
startActivity(i);
finish();
}
});
my error log:

error in this line:
tabLayout.setupWithViewPager(viewPager);
All the support libraries have to be the same version. Try changing either appcompat-v7 and support-v4 to 23.0.1 or design to 23.1.1
If you download higher version of support library, gradle uses upper version silently even if you defined as 23.1.1
.
You can check gradlew app:dependencies -q
whether correct version is used or not.
To fix its upper version handover, set force = true
to all of support libraries as below.
compile ('com.android.support:support-v4:23.1.1'){
force = true;
}
compile ('com.android.support:appcompat-v7:23.1.1'){
force = true;
}
compile ('com.android.support:design:23.1.1'){
force = true;
}
compile ('com.android.support:cardview-v7:23.1.1'){
force = true;
}
compile ('com.android.support:recyclerview-v7:23.1.1'){
force = true;
}
I fixed a similar issue by changing my dependence from:
compile 'com.android.support:design:23.1.1'
to
compile 'com.android.support:design:23.+'
My units at the end were in this way:
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.0.0'
compile 'com.android.support:cardview-v7:23.0.0'
compile 'com.android.support:design:23.+'
I think that is because the lib "compile 'com.mcxiaoke.volley:library-aaa:1.0.0' " used in your gradle including the different version of 'com.android.support::' as define in your gradle.
so you should do it like:
compile ('com.mcxiaoke.volley:library-aaa:1.0.0') {
transitive = false
}
I solved this issues by adding compile 'com.android.support:design:23.+' though my supporting dependencies are similar
Before
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:design:23.1.1'
After - this works for me
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:design:23.+'
