如何在Android的NavigationView上向项目添加点击事件 [英] How to add click event to item on NavigationView of Android

问题描述

我正在尝试在Android项目中实现侧边栏 NavigationDrawer .为此，我在 DrawerLayout 中使用了 NavigationView .为了显示项目，我使用了菜单.我想在该添加的菜单项上添加点击事件.

I am trying to implement Sidebar NavigationDrawer in my Android project. To do so, I have used NavigationView in DrawerLayout. To show items I used menu. I want to add click event on that added menu items.

参考代码:在导航菜单中-

Code for reference: In navigation menu -

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/nav_account" android:title="My Account"/>
    <item android:id="@+id/nav_settings" android:title="Settings"/>
    <item android:id="@+id/nav_layout" android:title="Log Out"/>
</menu>

在视图中:

<android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@menu/navigation_menu"
        android:layout_gravity="start" />

推荐答案

1. 在您的活动"中实现侦听器:

1. Implement the listener in your Activity:

public class HomeActivity extends AppCompatActivity implements 
              NavigationView.OnNavigationItemSelectedListener

Activity的onCreate中的

setNavigationItemSelectedListener

setNavigationItemSelectedListener in onCreate of Activity

NavigationView mNavigationView = (NavigationView) findViewById(R.id.account_navigation_view);

if (mNavigationView != null) {
        mNavigationView.setNavigationItemSelectedListener(this);
}

覆盖方法

Override the method

public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    if (id == R.id.nav_account) {
       // DO your stuff 
    }
}
