I think this is because you set the state to LOCKED_CLOSED so you cannot move from this state until you set it to the _UNLOCKED state. Check my answer here: https://stackoverflow.com/a/50304856/2873702

Basically you have to recall the function

drawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

with the UNLOCKED parameter instead. I suggest to try using it in the onBackPressed function. You should do something like

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.START)) {
    drawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
    drawer.closeDrawer(GravityCompat.START);
    drawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
    }else{
        super.onBackPressed();
    }
}

You need to close it programmatically because drawer is in lock mode and this will not be automatically close. Implement this method in your activity so that you can close it with programmatically.

See the documentation of DrawerLayout.LOCK_MODE_LOCKED_CLOSED

@Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        }else{
            super.onBackPressed();
        }
    }
