I am using collapsible action bar. While trying to start new activity got error: Cannot resolve constructor 'Intent(anonymous android.support.design.widget.NavigationView.OnNavigationItemSelectedListener, java.lang.Class)'
Please help me on this:
Can we use start new activity from navigation drawer menu item click ?
Or
We have only option to replace and show fragments from navigation drawer on menu item click
FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.containerView,new SentFragment()).commit();
if yes, then how can I replace tab activity and viewpager and set action bar height ?

According to Android Docs to start new activity you have to do:
1) Add this line in your class:
import android.content.Intent;
2) Add new activity to manifest, looks like this:
<activity
android:name=".YourActivityName"
android:label="YourActivityName">
<intent-filter>
<action android:name="package.name.YOURACTIVITYNAME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
3) Start activity with startActivity() method, like this:
Intent newAct = new Intent(getApplicationContext(), YourActivityName.class);
startActivity(newAct);
3a) If your class extends Activity you can pass this instead of getApplicationContext():
Intent newAct = new Intent(this, YourActivityName.class);
startActivity(newAct);
3b) If your class extends Fragment you must use getActivity() to pass Context:
Intent newAct = new Intent(getActivity(), YourActivityName.class);
startActivity(newAct);
