Question

我有这个导航抽屉，它工作得非常好。重构我的代码我删除了活动中的所有onOptionsItemSelecteds，并使所有活动都继承自扩展AppComplatActivity和实现所有必要方法的基本活动。在此之后，即使我有syncstate（）和所有东西，点击汉堡包图标也不再有效。

为什么这不起作用的任何线索？

其中一项活动：

public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {

NavigationView navigationView;
DrawerLayout drawerLayout;

private Tracker mTracker;

@Override
protected void onResume() {
    super.onResume();
    drawerLayout.openDrawer(GravityCompat.START);
}

@Override
protected void onPostResume() {
    super.onPostResume();
    mTracker.setScreenName("MainActivity" + "-----");
    mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerLayout.openDrawer(GravityCompat.START);
    navigationView = (NavigationView) findViewById(R.id.navigation_view_primary);
    navigationView.setNavigationItemSelectedListener(new NavigationDrawerListener(this));
    setupToolbar();
    Haftdong application = (Haftdong) getApplication();
    mTracker = application.getDefaultTracker();
}

private void setupToolbar() {
    // Show menu icon
    final ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);// will make the icon clickable and add the < at the left of the icon.
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    mDrawerToggle.syncState();//for hamburger icon
}

@Override
public void onFragmentInteraction(Uri uri) {
}

}

BaseActivity：

public class BaseActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@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_base, 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();
    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

您正在使用var async = require('async'); async.waterfall([ function function_1(callback) { var curr_1 = coll_1.find({}) curr_1.each(function(err, doc) { if (err) { callback(err, null) } else { allback(null, doc) } }); }, function function_2(obj, callback) { coll_2.findOne({}, function(err, document) { if (err) { callback(err, null); } else { dosomeprocess(obj) callback(null, obj); } }) } ], function done() { obj.db.close(); process.exit(); });的四参数构造函数，这意味着您必须在CREATE TABLE helpToolStatsTest ( customer nvarchar2(25), data nvarchar2(7), myDate Date DEFAULT CURRENT_DATE NOT NULL )中调用切换的ActionBarDrawerToggle方法＆{ ＃39; s onOptionsItemSelected()覆盖以打开/关闭抽屉。

例如：

MainActivity

如果您恰好提供自己的onOptionsItemSelected() - 例如，作为支持@Override public boolean onOptionsItemSelected(MenuItem item) { if(mDrawerToggle.onOptionsItemSelected(item)) { return true; } return super.onOptionsItemSelected(item); }（虽然没有必要设置它） - 那么您可以改为通过Toolbar {1}}作为ActionBar构造函数调用中的第三个参数。例如：

Toolbar

抽屉打开/关闭将在内部由ActionBarDrawerToggle处理，您无需拨打Toolbar toolbar = findViewById(R.id.toolbar); ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);中的切换。

此设置也不需要ActionBarDrawerToggle来电，如果您不想将onOptionsItemSelected()设置为setDisplayHomeAsUpEnabled()，则会很方便。

单击工具栏上的汉堡图标无法打开导航抽屉
