您可以使用android设计支持库创建NavigationView,而无需创建listview或RecyclerView,它们都是由android创建的。
要将其添加到您的项目中,您需要将 android 设计支持库添加到您的项目中,在 build.gradle 中添加以下行
compile 'com.android.support:design:22.2.0
查看android设计支持功能here
首先创建一个header(header.xml)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="190dp"
android:background="@drawable/background_material"
android:orientation="vertical"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="nyname"
</RelativeLayout>
接下来创建一个菜单资源文件,菜单中的项目将是抽屉中显示的项目(drawer.xml)
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/first1"
android:checked="false"
android:icon="@drawable/icon1"
android:title="@string/string1" />
<item
android:id="@+id/second2"
android:checked="false"
android:icon="@drawable/icon2"
android:title="@string/string2" />
</menu>
接下来创建一个DrawerLayout 文件,在drawerlayout 中你可以看到我包含了一个Toolbar 和一个“FrameLayout”。当点击drawerlayout中的item时,可以替换fragment。
其中还有带有这些参数的 NavigationView:
app:headerLayout="@layout/header"
app:menu="@menu/drawer"
android:layout_gravity="start"
app:headerLayout 是我们在步骤 1 中创建的 header.xml。
app:menu 是菜单资源项,即drawer.xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
>
<include
android:id="@+id/toolbar"
layout="@layout/tool_bar"
/>
<FrameLayout
android:id="@+id/frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
app:headerLayout="@layout/header"
app:menu="@menu/drawer"
/>
</android.support.v4.widget.DrawerLayout>
接下来在您的 MainActivity 中扩展 AppcompatActivity,
public class MainActivity extends AppCompatActivity {
............................................
初始化 NavigationView 并调用 setNavigationItemSelectedListener 获取点击事件,
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initializing Toolbar and setting it as the actionbar
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//Initializing NavigationView
navigationView = (NavigationView) findViewById(R.id.navigation_view);
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if(menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()){
//Replacing the main content with ContentFragment
case R.id.first1:
SomeFragment fragment = new SomeFragment();
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame,fragment);
fragmentTransaction.commit();
return true;
