Here my navigation drawer intent was working fine while but after adding tabs to the actionbar i cant intent to other pages from navigation bar.
For example: if i click navigation bar and select "settings" tab it's not directing to settings layout. Kindly give better suggestions so as it helps me out in future.

I am new with Android development, so this is probably a rookie mistake but, I am stuck.
I want to start an activity when clicking on the menu, but the following exception shows up:

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.mygymroutine.mygymroutine.activities.ActivitySchedule">
</android.support.constraint.ConstraintLayout>
Here:
getSupportFragmentManager().beginTransaction().add(R.id.fragment_schedule, fg)
.commit();
You are passing R.id.fragment_schedule as the container of the fragment. Where the fragment will be inserted. However, R.id.fragment_schedule is part of your Fragment. So, it was not inflated yet. You can't use it as container since it was not created yet.
I think you want is:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.mygymroutine.mygymroutine.activities.ActivitySchedule"
<!-- ADD LINE BELOW -->
android:id="#+id/fragment_container" >
</android.support.constraint.ConstraintLayout>
And change this:
getSupportFragmentManager().beginTransaction().add(R.id.fragment_schedule, fg)
.commit();
to this:
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, fg)
.commit();
In. The onOptionsItemSelected method add the following
(This method brings a parameter - MenuItem item)
switch (item.getItemId())
case R.id.myFirst
startActivity(new Intent(this, MyFirstActivity.class));
case R.id.mySecond
startActivity (newIntent(this, MySecondActivity.class));
And so on. You may define a layout for the activity with necessary views. You may also declare the activity in the Manifest file.
This works. I am starting my activities from the main like this.
I'm working the first time with Fragments, so sorry if I did smt very stupid :D
I have a Navigation Drawer Activity. When I click in it on the first item i want to open a Fragment. When I open it, there is not only the Layout of the Fragment shown, but also the layout of my MainActivity, it looks very strange.
[1]: https://i.stack.imgur.com/iqTAq.png MainActivity

[3]: https://i.stack.imgur.com/T2vDJ.png First Fragment
How can I solve the problem?
Here is my code if you need it:
MainActivity(Navigation Drawer Templated, I wrote only in the onNavigationItemSelected, so that it goes to the fragment when I click on the first item:

fab.setOnClickListener(new View.OnClickListener() {

.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement

return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {

first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, first).commit();
} else if (id == R.id.nav_gallery) {

I hope someone can help me :)
Add a background to your fragment layout, it should solve your problem.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white" //Your background color
tools:context="com.gsr.fragmenttest.first">
<!-- TODO: Update blank fragment layout -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
...
I think the problem is in your activity layout
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
try to change your main activity layout like above. Hope it will solve your problem.
1) implements first.OnOnFragmentInteractionListener
2) in onNavigationItemSelected method put this code
if (id == R.id.nav_camera) {
setTitle("First Fragment");
first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, new first()).commit();
3)In first fragment use this line
import android.app.Fragment;
I have created a Navigation Drawer "BaseActivity" to be extended by multiple activities however when I open the Navigation Drawer none of the menu items can be clicked, there is a semi-opaque layer over them which suggests to me the z-order in which they are loaded is incorrect. How would I go about fixing this?

If the problem is with the Z-index as you said, then you can make it always on top using bringToFront() call this method to your DrawerLayout or NavigationView!
I am having trouble implementing both Navigation drawer and swipe tabs.
When I use navigation drawer and I click on some items a new fragment replaces a FrameView (called content_frame) in my project. The problem became apparent when I implemented swipe tabs using PageAdapter. Now when I click on navigation drawer and a new Fragment is commited into content_frame it overlaps with current Tab.
It's because I use content_frame to replace fragments from Navigation drawer and use pageadapter to create 3 fixed tabs. Is there a way to make it so for example a fragment would replace current tab or tabs would just dynamically load into a FrameLayout like my content_frame? It would help with further development as well.
