        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        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);


        recyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
        recyclerView.setHasFixedSize(true);
        db= new DatabaseHelper(this);
        searchView = (SearchView) findViewById(R.id.searchView);

由于

Answer 1

如果您想使用ads:adSize="SMART_BANNER"，则必须将android:layout_width设为match_parent。否则，您可以使用ads:adSize="BANNER"

Answer 2

添加此项以查看是否有任何错误。

mAdView.setAdListener(new AdListener() {
    @Override
    public void onAdLoaded() {

    }

    @Override
    public void onAdFailedToLoad(int errorCode) {
       ..  print the error code to see if there is one
    }

    @Override
    public void onAdOpened() {

    }

    @Override
    public void onAdLeftApplication() {
    }

    @Override
    public void onAdClosed() {

    }
});
