Android 高仿QQ5.2双向側滑菜单DrawerLayout实现源代码

左右側滑效果图

1.主页的实现

直接将DrawerLayout作为根布局，然后其内部第一个View为内容区域，第二个View为左側菜单，第三个View为右側側滑菜单，当前第三个是可选的。

布局：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/id_drawerLayout"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/img_frame_background" ><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/qq" ><Buttonandroid:layout_width="40dp"android:layout_height="30dp"android:layout_marginTop="10dp"android:layout_alignParentRight="true"android:layout_alignParentEnd="true" android:background="@drawable/youce"android:onClick="OpenRightMenu" /></RelativeLayout><fragmentandroid:id="@+id/id_left_menu"android:name="com.pcachy.drawerlayout.MenuLeftFragment"android:layout_width="200dp"android:layout_height="match_parent"android:layout_gravity="start"android:tag="LEFT" /><fragmentandroid:id="@+id/id_right_menu"android:name="com.pcachy.drawerlayout.MenuRightFragment"android:layout_width="100dp"android:layout_height="match_parent"android:layout_gravity="end"android:tag="RIGHT" /></android.support.v4.widget.DrawerLayout>

代码

package com.pcachy.drawerlayout;import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.widget.DrawerLayout;
import android.view.Gravity;
import android.view.View;
import android.view.Window;import com.nineoldandroids.view.ViewHelper;public class MainActivity extends FragmentActivity {private DrawerLayout mDrawerLayout;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);//requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);initView();initEvents();}private void initView(){mDrawerLayout = (DrawerLayout) findViewById(R.id.id_drawerLayout);mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.END);}private void initEvents(){mDrawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {@Overridepublic void onDrawerSlide(View drawerView, float slideOffset) {// TODO Auto-generated method stubView mContent = mDrawerLayout.getChildAt(0);View mMenu = drawerView;float scale = 1 - slideOffset;float rightScale = 0.8f + scale * 0.2f;if (drawerView.getTag().equals("LEFT")){float leftScale = 1 - 0.3f * scale;ViewHelper.setScaleX(mMenu, leftScale);ViewHelper.setScaleY(mMenu, leftScale);ViewHelper.setAlpha(mMenu, 0.6f + 0.4f * (1 - scale));ViewHelper.setTranslationX(mContent,mMenu.getMeasuredWidth() * (1 - scale));ViewHelper.setPivotX(mContent, 0);ViewHelper.setPivotY(mContent,mContent.getMeasuredHeight() / 2);mContent.invalidate();ViewHelper.setScaleX(mContent, rightScale);ViewHelper.setScaleY(mContent, rightScale);} else{ViewHelper.setTranslationX(mContent,-mMenu.getMeasuredWidth() * slideOffset);ViewHelper.setPivotX(mContent, mContent.getMeasuredWidth());ViewHelper.setPivotY(mContent,mContent.getMeasuredHeight() / 2);mContent.invalidate();ViewHelper.setScaleX(mContent, rightScale);ViewHelper.setScaleY(mContent, rightScale);}}@Overridepublic void onDrawerOpened(View drawerView) {// TODO Auto-generated method stub}@Overridepublic void onDrawerClosed(View drawerView) {// TODO Auto-generated method stubmDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.RIGHT);}@Overridepublic void onDrawerStateChanged(int newState) {// TODO Auto-generated method stub}});}public void OpenRightMenu(View view){mDrawerLayout.openDrawer(Gravity.RIGHT);mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED, Gravity.RIGHT);}}

2.左菜单和右菜单布局(左菜单和右菜单的布局和代码随便你怎么写，这里是左菜单的样例)

<?

xml version="1.0" encoding="utf-8"?

> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#00000000" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:orientation="vertical" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:id="@+id/one" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:src="@drawable/img_1" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_toRightOf="@id/one" android:text="第1个Item" android:textColor="#f0f0f0" android:textSize="20sp" /> </RelativeLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:id="@+id/two" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:src="@drawable/img_2" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_toRightOf="@id/two" android:text="第2个Item" android:textColor="#f0f0f0" android:textSize="20sp" /> </RelativeLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:id="@+id/three" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:src="@drawable/img_3" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_toRightOf="@id/three" android:text="第3个Item" android:textColor="#f0f0f0" android:textSize="20sp" /> </RelativeLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:id="@+id/four" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:src="@drawable/img_4" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_toRightOf="@id/four" android:text="第4个Item" android:textColor="#f0f0f0" android:textSize="20sp" /> </RelativeLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:id="@+id/five" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" android:src="@drawable/img_5" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_toRightOf="@id/five" android:text="第5个Item" android:textColor="#f0f0f0" android:textSize="20sp" /> </RelativeLayout> </LinearLayout> </RelativeLayout>

1、为了模拟QQ的右側菜单须要点击才干出现。所以在初始化DrawerLayout的时候，使用了mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT);意思是仅仅有编程才干将其弹出。然后在弹出以后。须要让手势能够滑动回去，所以在OpenRightMenu中又编写了：mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED,Gravity.RIGHT); UNLOCK了一下。

最后在onDrawerClosed回调中。继续设置mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT)。

2、动画效果动画用了nineoldandroids。

3、setDrawerListener
通过代码也能看出来，能够使用setDrawerListener监听菜单的打开与关闭等等。这里对于当前操作是哪个菜单的推断是通过TAG推断的。我认为使用gravity应该也能推断出来
