How to add click event to item on NavigationView of Android

问题

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.

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>

In View:

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

Implement the listener in your Activity:

public class HomeActivity extends AppCompatActivity implements 
              NavigationView.OnNavigationItemSelectedListener

setNavigationItemSelectedListener in onCreate of Activity

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

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

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 }
    ...
}

You have to use OnNavigationItemSelectedListener(MenuItem item) method.

for more check this documentation.

Here is a Java 8 approach with smaller boilerplate (no "implements" on Activity). Also helpful if your class is abstract and you don't want to implement this functionality in every other child:

@Override
protected void onCreate(
  Bundle savedInstanceState) {

  NavigationView navigationView =
    findViewById(
      R.id.navigationView);

  navigationView.setNavigationItemSelectedListener(
    MyActivity::onNavigationItemSelected);
}

public static boolean onNavigationItemSelected(MenuItem item) {

  if (item.getId() == R.id.my_item) {
    myItemClickHandler();
  }

  return false;
}
