安卓:导航菜单不适用于按钮，但适用于触摸

Question

嗨！

我在安卓应用程序中构建了一个导航抽屉。我使用了 http://blog.teamtreehouse.com/add-navigation-drawer-android 的操作方法，并在布局的一个地方对其进行了修改。当我从左到右触摸和摆动手指时，我可以激活菜单。但是，如果我触摸汉堡菜单，则不会有任何意外。怎么了？如果我在菜单中滑动，图标将变为箭头，因此存在连接。希望有人能帮助我。

我的Java类（主要活动）：

public class AmericanFootball extends AppCompatActivity {
    private MenuItem mi;
    public static Context context;
    private ListView mDrawerList;
    private ArrayAdapter<String> mAdapter;
    private ActionBarDrawerToggle mDrawerToggle;
    private DrawerLayout mDrawerLayout;
    private String mActivityTitle;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        context = (Context) this;
        setContentView(R.layout.activity_american_football);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitle(getText(R.string.app_name));
        setSupportActionBar(toolbar);
        mDrawerList = (ListView)findViewById(R.id.navList);
        mDrawerLayout = (DrawerLayout)findViewById(R.id.drawerLayout);
        mActivityTitle = getTitle().toString();
        addDrawerItems();
        setupDrawer();
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        checkInternet ci = new checkInternet();
        boolean internet=ci.isNetzwerkVerfuegbar((Context) this);
        TextView tv = (TextView) findViewById(R.id.tv_hello);
        tv.setTypeface(FontManager.getTypeface((Context) this, FontManager.FONTAWESOME));
        tv.setText(R.string.fa_icon_areachart);
        tv.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimaryLight));
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_american_football, menu);
        MenuItem mi = menu.findItem(R.id.action_refresh);
        TextDrawable td = new TextDrawable((Context) this);
        td.setText(getString(R.string.fa_refresh));
        td.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimaryLight));
        td.setTextSize(30);
        mi.setIcon(td);
        LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        ImageView iv = (ImageView)inflater.inflate(R.layout.iv_refresh, null);
        iv.setImageDrawable(td);
        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
        if (id == R.id.action_settings) {
            return true;
        }
        if (id == R.id.action_refresh) {
            doRefreshGames(item);
        }
        return super.onOptionsItemSelected(item);
    }
    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
    private void addDrawerItems() {
        String[] osArray = { "Android", "iOS", "Windows", "OS X", "Linux" };
        mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, osArray);
        mDrawerList.setAdapter(mAdapter);
        mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(AmericanFootball.this, "Time for an upgrade!", Toast.LENGTH_SHORT).show();
            }
        });
    }
    private void setupDrawer() {
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) {
            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getSupportActionBar().setTitle("Navigation!");
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getSupportActionBar().setTitle(mActivityTitle);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        };
        mDrawerToggle.setDrawerIndicatorEnabled(true);
        mDrawerLayout.setDrawerListener(mDrawerToggle);
    }
}

我发现了我的错误。忘了一件小事：

public boolean onOptionsItemSelected(MenuItem item) {
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
}
