我在我的应用中创建了侧边栏导航。现在我想在其上创建一个click事件。
我已经搜索过了,我收到了文档,但是我无法理解。
所以请任何人都可以建议一个更好的来源,这将有所帮助。 youtube上的教程会有所帮助。
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/nav_account"
android:icon="@mipmap/ic_person_black_24dp"
android:title="My Account"/>
<item android:id="@+id/nav_setting"
android:icon="@mipmap/ic_settings_black_24dp"
android:title="Settings"/>
<item android:id="@+id/nav_logout"
android:icon="@mipmap/ic_logout_black_24dp"
android:title="Logout"/>
</menu>

答案 0 :(得分:0)
只需实现NavigationView.OnNavigationItemSelectedListener
接口,然后覆盖方法onNavigationItemSelected(MenuItem menuItem)
,如下所示:
public class MainActivity extends AppCompatActivity implements
NavigationView.OnNavigationItemSelectedListener{
NavigationView navigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// declaring the NavigationView
navigationView = (NavigationView) findViewById(R.id.navigationView);
// assigning the listener to the NavigationView
navigationView.setNavigationItemSelectedListener(this);
}
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
switch (menuItem.getItemId()) {
case R.id.nav_account:
// do you click actions for the first selection
break;
case R.id.nav_setting:
// do you click actions for the second selection
break;
case R.id.nav_logout:
// do you click actions for the third selection
break;
}
return true;
}
}
当然,不要忘记将id
提供给xml-layout中的NavigationView
:
<android.support.design.widget.NavigationView
android:id="@+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigation_header"
app:menu="@menu/navigation_menu">
</android.support.design.widget.NavigationView>
