一丶概述

Android側滑效果實現有很多種，這裡先說說，Android系統5.0後自帶的DrawerLayout + NavigationView。

二丶效果圖

三丶看程式碼

DrawerLayout + NavigationViewxml佈局

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/blue_bg">

<com.example.jinboy.codertodeveloperbytcler.java_demo.appdemo.ui.view.CircleImageView
android:id="@+id/iv_mine_avatar"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
android:layout_below="@+id/title_bar"
android:layout_marginStart="10dp"
android:src="@drawable/mine_me"/>

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="CSDN 部落格"
android:textColor="@android:color/black"
android:textSize="20sp"
android:textStyle="bold" />

</RelativeLayout>

</LinearLayout>

<android.support.design.widget.NavigationView
android:id="@+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header"
app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

NavigationView裡的headerLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/bg_evenings"
android:orientation="vertical">

<com.example.jinboy.codertodeveloperbytcler.java_demo.appdemo.ui.view.CircleImageView
android:id="@+id/iv_mine_avatar"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_below="@+id/title_bar"
android:layout_centerHorizontal="true"
android:layout_marginStart="10dp"
android:layout_marginTop="50dp"
android:src="@drawable/mine_me"/>

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:layout_marginEnd="10dp"
android:layout_marginStart="10dp"
android:layout_marginTop="20dp"
android:text="我的部落格地址：\nhttp://blog.csdn.net/dt235201314"
android:textColor="@color/white"
android:textSize="15sp"
android:textStyle="bold" />

</LinearLayout>

menu

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<group android:checkableBehavior="single">
<item
android:id="@+id/nav_csdn"
android:icon="@mipmap/mine_about_icon"
android:title="CSDN" />
<item
android:id="@+id/nav_jianshu"
android:icon="@mipmap/mine_about_icon"
android:title="簡書" />
</group>

</menu>

分別對應

屬性設定注意點：

1.android:layout_gravity="left"或者“star”表示從左邊彈出，這裡跟後面java程式碼關閉相關

drawerLayout.closeDrawer(GravityCompat.START);

2.app:itemIconTint="@color/blue" 設定選單選項圖片顏色，不寫預設為無色（灰色），如需要現實為圖片原本顏色java程式碼設定

navigationView.setItemIconTintList(null);

Activity java程式碼

public class MyCsdnActivity extends Activity implements NavigationView.OnNavigationItemSelectedListener {

private DrawerLayout drawerLayout;
private CircleImageView circleImageView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_csdn_activity);
initView();
}

private void initView() {
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
circleImageView = (CircleImageView) findViewById(R.id.iv_mine_avatar);
NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView);
navigationView.setNavigationItemSelectedListener(this);
navigationView.setItemIconTintList(null);
circleImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
drawerLayout.openDrawer(GravityCompat.START);
}
});
}

/**
* 選單點選響應函式
*
* @param item 選單
* @return boolean
*/
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
drawerLayout.closeDrawer(GravityCompat.START);
switch (item.getItemId()) {
case R.id.nav_csdn:
WebViewActivity.startWebViewActivity(this,"http://my.csdn.net/dt235201314");
break;
case R.id.nav_jianshu:
WebViewActivity.startWebViewActivity(this,"http://www.jianshu.com/u/905c7de5ae83");
break;
default:
}
return false;
}

/**
* 重寫返回鍵響應函式
*/
@Override
public void onBackPressed() {
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
drawerLayout.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
}

3.NavigationView頭部佈局的id

NavigationView navigationView = (NavigationView) findViewById(R.id.navigationView);
View headerView = navigationView.getHeaderView(0);
tv_name = (TextView) headerView.findViewById(R.id.tv_name);
tv_originalArticleNumber = (TextView) headerView.findViewById(R.id.tv_originalArticleNumber);
tv_visitNumber = (TextView) headerView.findViewById(R.id.tv_visitNumber);
