I tried different method, but each time my application crashes. Someone would have an idea of the problem? I have to do this on homework for school and I do not know how to solve this problem.
You are trying to cast LinearLayout into a ConstraintLayout
Change line LinearLayout paramLayout; to ConstraintLayout paramLayout; in your activity

I´ve set up an android app with navigation drawer activity. There is an image of the activity by default and I want to go back to start page by clicking it.
How can I do that?

In my MainActivity in the method onNavigationItemSelected I can switch in the menu, but if I address their the "androidImg" it doesn´t react...
I just have a simple navigation drawer with some linearlayout arranged horizontally.

Now On clicking to this dashboard layout.I want to move to dashboard fragment. Please note that both Navigationdrawer and Dialog fragment should be inside same activity.This is my activity class:
public class Home extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
LinearLayout dashboard;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
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.dashboard, 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();

if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
dashboard= (LinearLayout) findViewById(R.id.dashboard_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
I am just wondering how can I implement this. For clarity this is the screen shot of what I want.

In your main thread start a new thread and let that do all the work. Main should only initialize your app, not perform any other logic.
I have navigation drawer, and a button on the toolbar that when you click it it opens it and make some kind of nice animation.
I'm trying to move the button from the right side to the left side, but unsuccessfully.
I tried to change the gravity of it from start to end, but it didn't change it.
It was made by a template of android studio.
Moreover, when I click this Button it crashes me.
when I change the "android:supportsRtl" to false, it changes the side of the button to the left, as I want, but it then changes the side of the drawer as well.
and I also need to supportsRTL, so it's not a good solution. (I set it to "true" on the manifest)
What is the problem? and How can I get the Navigation Icon on the left side, with the nice animation?
BTH, how can I make the navigation be a little bit smaller(that I can see the toolbar) ?

Just use a custum view in the toolbar if you want something as custom as having the drawer toggle in the opposite side of the drawer.
Uppon click:
mDrawerLayout.closeDrawer(GravityCompat.START);
mDrawerLayout.openDrawer(GravityCompat.START);
And for the toolbar - you can just put the drawer below the toolbar in a vertical LinearLayout
In main activity add these lines:
android:layoutDirection="rtl"
android:textDirection="anyRtl"

Your activity layout is a bit odd. You should have a root parent layout like for example CoordinatorLayout.
Your XML layout however does not have a root layout, the LinearLayouts are all siblings.
Another thing I noticed is that the LinearLayout around the FAB is the one you replace when replacing your fragment. This is wrong. Remove LinearLayout around the FAB and add a FrameLayout with id=fragment_container.
The layout structure could look like this
<CoordinatorLayout>
<AppBarLayout>
<Toolbar/>
//... other layouts here
</AppBarLayout>
<FrameLayout
android:id="#+id/fragment_container"/>
//... rest of your layout here
<FloatingActionButton android:gravity="bottom|end" />
</CoordinatorLayout>
