我有一个带有底部菜单导航栏的Android Activity,它在三个片段和一个应该打开新活动的顶级菜单项之间导航,但顶级菜单ActionBar项目没有响应点击事件。也许有些东西不见了?或者我应该从我的片段中处理菜单?

这是我的代码:

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    // Set Network Connection Listener
    setConnectionListener(this);

    //check the network connectivity when activity is created
    checkConnection();

    BottomNavigationView bottomNavigation = (BottomNavigationView) findViewById(R.id.bottom_navigation);
    bottomNavigation.setOnNavigationItemSelectedListener(this);

    transaction = getSupportFragmentManager().beginTransaction();
    transaction.replace(R.id.frame_layout, HomeFragment.newInstance());
    transaction.commit();

    // Used to select item programmatically
    // bottomNavigation.getMenu().getItem(0).setChecked(true);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.top, menu);
    // return super.onCreateOptionsMenu(menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    Log.i(TAG, "Menu Clicked " + item.getItemId());
    switch (item.getItemId()){
        case R.id.tab_cart:
            Intent intent = new Intent(this, CartActivity.class);
            startActivity(intent);
            return true;
    }
    return super.onOptionsItemSelected(item);
}

我的菜单top.xml res菜单文件

<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.shopcentra.activities.MainActivity">
<item
    android:id="@+id/tab_cart"
    android:icon="@mipmap/cart"
    android:title="@string/cart"
    app:actionLayout="@layout/notification_layout"
    app:showAsAction="always">
</item>
</menu>

我无法在&#34; tab_cart&#34;上看到您添加了View.OnClickListener的位置。如果您已经设置了一个,请分享该代码,否则,在该视图上添加一个OnCLickListener,然后查看问题是否仍然存在。
编辑:在菜单项上添加OnClickListener的代码:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuItem tabCartMenuItem = menu.findItem(R.id.tab_cart);
    View notificationActionView = menuItem.getActionView();
    notificationActionView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onOptionsItemSelected(tabCartMenuItem));
        }
    });
}

尝试将此代码添加到onCreateOptionsMenu()方法。
