问题描述
我已经在Android中制作了一个导航抽屉，我想在其中实现onClick.这是我的主要活动:
I have made a navigation drawer in Android in which I want to implement onClick for it. This is my main activity:
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle aToggle;
private Toolbar toolbar;
private RecyclerView recyclerView;
private RecyclerAdapter recyclerAdapter;
private RecyclerView.Adapter adapter;
private NavigationView navigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
aToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.navig, R.string.open, R.string.Close);
navigationView = (NavigationView) findViewById(R.id.nav_view);
mDrawerLayout.addDrawerListener(aToggle);
toolbar = (Toolbar) findViewById(R.id.nav_action);
toolbar.setNavigationIcon(R.drawable.navig);
setSupportActionBar(toolbar);
aToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
navigationView.setItemIconTintList(null);
recyclerView = (RecyclerView) findViewById(R.id.recycler);
recyclerAdapter = new RecyclerAdapter(getApplicationContext());
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(this, 2);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerAdapter);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (aToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}}
这是我的活动XML布局:
This is my XML layout for the activity:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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"
android:id="@+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.alpit.formula2.MainActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="0dp"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="58dp"
android:orientation="vertical"></android.support.v7.widget.RecyclerView>
<android.support.v7.widget.Toolbar
android:id="@+id/nav_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#EF6C00"
android:orientation="vertical"
android:theme="@style/ThemeOverlay.AppCompat.Dark"></android.support.v7.widget.Toolbar>
</RelativeLayout>
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFA726"
app:menu="@menu/navigation_menu"
app:theme="@style/NavigationTheme">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
这是我的菜单项:
<group
android:id="@+id/gp1"
android:checkableBehavior="single">
<item
android:id="@+id/nav_maths"
android:icon="@drawable/maths"
android:title="Maths" />
<item
android:id="@+id/nav_physics"
android:icon="@drawable/physics"
android:title="Physics" />
<item
android:id="@+id/nav_chem"
android:icon="@drawable/chem"
android:title="Chemistry" />
<item
android:id="@+id/EEE"
android:icon="@drawable/lightbulb"
android:title="Electronics Electrical" />
</group>
<group
android:id="@+id/gp2"
android:checkableBehavior="single">
<item
android:id="@+id/unitconversion"
android:icon="@drawable/unitconversion"
android:title="Unit Conversion" />
<item
android:id="@+id/Scientist"
android:icon="@drawable/scientist"
android:title="Scientist" />
<item
android:id="@+id/favourite"
android:icon="@drawable/favourite"
android:title="Favourite" />
</group>
<group
android:id="@+id/gp3"
android:checkableBehavior="single">
<item
android:id="@+id/Share"
android:icon="@drawable/share"
android:title="Share" />
<item
android:id="@+id/Rate"
android:icon="@drawable/rate"
android:title="Rate" />
<item
android:id="@+id/ads"
android:icon="@drawable/ad"
android:title="Remove Ads" />
<item
android:id="@+id/aboutus"
android:icon="@drawable/aboutus"
android:title="About Us" />
</group>
</menu>
问题是我无法理解如何在导航抽屉中实现onClick，因为它是由我们给定的列表而不是由任何listView填充的.
The problem is I am not able to understand how to implement the onClick on the navigation drawer as it is populated by the list given by us not by any listView.

How can I implement onClick on the items of navigation drawer?
推荐答案
您需要添加 实现NavigationView.OnNavigationItemSelectedListener
You need to add implements NavigationView.OnNavigationItemSelectedListener
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener
并添加方法
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
// Handle navigation view item clicks here.
switch (item.getItemId()) {
case R.id.nav_maths: {
//do somthing
break;
}
}
//close navigation drawer
mDrawerLayout.closeDrawer(GravityCompat.START);
return true;
}
设置监听器的方法
private void setNavigationViewListener() {
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
onCreate()中的
调用方法
call method in onCreate()
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setNavigationViewListener()
}
