Navigation drawer is under other widgets

I'm trying to add fragment with Navigation drawer to the main activity, where are two buttons. However, when Navigation drawer is opened, buttons are above it. Moreover, Navigation drawer is not clickable, but buttons are.

Here is my code.

Activity ActionBar is invisible in fragment

I have problem with ActionBar in my fragment. It's invisible in it, so I can't execute getActionBar().setDisplayHomeAsUpEnabled(true); in my SignUpActivity.java. In every other Activity (not Fragment) it's visible.
Could You tell me what I am doing wrong? Probably something is missing.

You can use Toolbar inside an AppBarLayout in your activity:
SignUpActivity.java
...
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final ActionBar ab = getSupportActionBar();
ab.setHomeAsUpIndicator(R.drawable.ic_menu);
ab.setDisplayHomeAsUpEnabled(true);
...

Would appreciate too much if I get somebody to assist me. Regards.

At this line:
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_background_123);
you are decoding high resolution image. In order to manage that with a library you can use one of these:
Glide
picasso
or if you want to generate palette by picasso first read this article
Picassopalette
is another library you can use to generate palette by picasso.
or you can use this code for glide:
Glide.with(this)
.load(your image path,id,...)
.asBitmap()
.into(new SimpleTarget<Bitmap>() {
#Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
Palette.Builder palette = Palette.from(resource);
palette.generate(new Palette.PaletteAsyncListener() {
#Override
public void onGenerated(Palette palette) {
}
});
}
});

Try by add header view to your listview (header will also scroll in this case), You need to do like this in your MainActivity :
View header = (View) getLayoutInflater().inflate(
R.layout.header_layout, null);
ImageView img=(ImageView)header.findViewById(R.id.imgView);
img.setBackgroundResource(R.drawable.icon);
mainListView.addHeaderView(header);
Or you can use DesignLibrary like here or here.

Add another view in your XML and position it above activity_main_drawer inside your DrawerLayout. The header is probably not supposed to scroll so it shouldn't be in your listview. Also, remove drawer_image from the listview item layout. Since it's not supposed to be in all the items.

Or use http://developer.android.com/reference/android/support/design/widget/NavigationView.html and add your image as header view.
navView = (NavigationView) findViewById(R.id.navView);
navView.inflateHeaderView(R.layout.myheader)
or in XML
app:headerLayout="#layout/myheader"
