Android DrawerLayout 高仿QQ5.2双向侧滑菜单

转载出处:http://blog.csdn.net/lmj623565791/article/details/41531475

1、概述

之前写了一个Android 高仿 QQ5.0 侧滑菜单效果 自定义控件来袭 ,恰逢QQ5.2又加了一个右侧菜单,刚好看了下DrawerLayout,一方面官方的东西,我都比较感兴趣;另一方面,这玩意用起来的确方便,于是简单写了个demo,高仿QQ5.2双向侧滑,分享给大家。

首先看看效果图:

DrawerLayout用起来真的很方便,下面一起看看用法~

2、DrawerLayout的使用

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为左侧菜单,第三个View为右侧侧滑菜单,当前第三个是可选的。

第一个View的宽高应当设置为match_parent,当然了,这也理所当然。

第二、三个View需要设置android:layout_gravity=”left”,和android:layout_gravity=”right”且一搬高度设置为match_parent,宽度为固定值,即侧滑菜单的宽度。

按照上面的描述写个布局文件,然后设置给Activity就添加好了左右侧滑了,是不是很简单~~~

比如我们的布局文件:

  1. <android.support.v4.widget.DrawerLayout xmlns:android=“http://schemas.android.com/apk/res/android”
  2.     xmlns:tools=“http://schemas.android.com/tools”
  3.     android:id=“@+id/id_drawerLayout”
  4.     android:layout_width=“match_parent”
  5.     android:layout_height=“match_parent”
  6.     android:background=“@drawable/img_frame_background” >
  7.     <RelativeLayout
  8.         android:layout_width=“match_parent”
  9.         android:layout_height=“match_parent”
  10.         android:background=“@drawable/qq” >
  11.         <Button
  12.             android:layout_width=“40dp”
  13.             android:layout_height=“30dp”
  14.              android:layout_marginTop=“10dp”
  15.             android:layout_alignParentRight=“true”
  16.             android:background=“@drawable/youce”
  17.             android:onClick=“OpenRightMenu” />
  18.     </RelativeLayout>
  19.     <fragment
  20.         android:id=“@+id/id_left_menu”
  21.         android:name=“com.zhy.demo_zhy_17_drawerlayout.MenuLeftFragment”
  22.         android:layout_width=“200dp”
  23.         android:layout_height=“match_parent”
  24.         android:layout_gravity=“left”
  25.         android:tag=“LEFT” />
  26.     <fragment
  27.         android:id=“@+id/id_right_menu”
  28.         android:name=“com.zhy.demo_zhy_17_drawerlayout.MenuRightFragment”
  29.         android:layout_width=“100dp”
  30.         android:layout_height=“match_parent”
  31.         android:layout_gravity=“right”
  32.         android:tag=“RIGHT” />
  33. </android.support.v4.widget.DrawerLayout>

这里我们的主内容区域为RelativeLayout

菜单用的两个Fragment,左侧为200dp,右侧为100dp;

好了,看了我们的布局文件,接下来看下我们的详细代码。

3、代码是最好的老师

1、MenuLeftFragment

  1. package com.zhy.demo_zhy_17_drawerlayout;
  2. import android.os.Bundle;
  3. import android.support.v4.app.Fragment;
  4. import android.view.LayoutInflater;
  5. import android.view.View;
  6. import android.view.ViewGroup;
  7. public class MenuLeftFragment extends Fragment
  8. {
  9.     @Override
  10.     public View onCreateView(LayoutInflater inflater, ViewGroup container,
  11.             Bundle savedInstanceState)
  12.     {
  13.         return inflater.inflate(R.layout.layout_menu, container, false);
  14.     }
  15. }

  115.         </RelativeLayout>
  116.     </LinearLayout>
  117. </RelativeLayout>

其实就是堆出来的布局~~没撒意思~

2、MenuRightFragment

  1. package com.zhy.demo_zhy_17_drawerlayout;
  2. import android.os.Bundle;
  3. import android.support.v4.app.Fragment;
  4. import android.view.LayoutInflater;
  5. import android.view.View;
  6. import android.view.ViewGroup;
  7. public class MenuRightFragment extends Fragment
  8. {
  9.     @Override
  10.     public View onCreateView(LayoutInflater inflater, ViewGroup container,
  11.             Bundle savedInstanceState)
  12.     {
  13.         return inflater.inflate(R.layout.menu_layout_right, container, false);
  14.     }
  15. }

对应布局文件:

  1. <?xml version=“1.0” encoding=“utf-8”?>
  2. <LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android”
  3.     android:layout_width=“match_parent”
  4.     android:layout_height=“match_parent”
  5.     android:gravity=“center_vertical”
  6.     android:orientation=“vertical” >
  7.     <LinearLayout
  8.         android:layout_width=“match_parent”
  9.         android:layout_height=“wrap_content”
  10.         android:layout_centerVertical=“true”
  11.         android:layout_gravity=“center_vertical”
  12.         android:layout_marginBottom=“20dp”
  13.         android:orientation=“vertical” >
  14.         <ImageView
  15.             android:layout_width=“60dp”
  16.             android:layout_height=“60dp”
  17.             android:layout_gravity=“center”
  18.             android:src=“@drawable/wode” />
  19.         <TextView
  20.             android:layout_width=“fill_parent”
  21.             android:layout_height=“wrap_content”
  22.             android:gravity=“center”
  23.             android:text=“扫一扫”
  24.             android:textColor=“#ffffff” />
  25.     </LinearLayout>
  26.     <LinearLayout
  27.         android:layout_width=“match_parent”
  28.         android:layout_height=“wrap_content”
  29.         android:layout_centerVertical=“true”
  30.         android:layout_gravity=“center_vertical”
  31.         android:layout_marginBottom=“20dp”
  32.         android:orientation=“vertical” >
  33.         <ImageView
  34.             android:layout_width=“60dp”
  35.             android:layout_height=“60dp”
  36.             android:layout_gravity=“center”
  37.             android:src=“@drawable/saoma” />
  38.         <TextView
  39.             android:layout_width=“fill_parent”
  40.             android:layout_height=“wrap_content”
  41.             android:gravity=“center”
  42.             android:text=“讨论组”
  43.             android:textColor=“#ffffff” />
  44.     </LinearLayout>
  45.     <LinearLayout
  46.         android:layout_width=“match_parent”
  47.         android:layout_height=“wrap_content”
  48.         android:layout_centerVertical=“true”
  49.         android:layout_gravity=“center_vertical”
  50.         android:layout_marginBottom=“20dp”
  51.         android:orientation=“vertical” >
  52.         <ImageView
  53.             android:layout_width=“60dp”
  54.             android:layout_height=“60dp”
  55.             android:layout_gravity=“center”
  56.             android:src=“@drawable/wode” />
  57.         <TextView
  58.             android:layout_width=“fill_parent”
  59.             android:layout_height=“wrap_content”
  60.             android:gravity=“center”
  61.             android:text=“扫一扫”
  62.             android:textColor=“#ffffff” />
  63.     </LinearLayout>
  64.     <LinearLayout
  65.         android:layout_width=“match_parent”
  66.         android:layout_height=“wrap_content”
  67.         android:layout_centerVertical=“true”
  68.         android:layout_gravity=“center_vertical”
  69.         android:layout_marginBottom=“20dp”
  70.         android:orientation=“vertical” >
  71.         <ImageView
  72.             android:layout_width=“60dp”
  73.             android:layout_height=“60dp”
  74.             android:layout_gravity=“center”
  75.             android:src=“@drawable/saoma” />
  76.         <TextView
  77.             android:layout_width=“fill_parent”
  78.             android:layout_height=“wrap_content”
  79.             android:gravity=“center”
  80.             android:text=“讨论组”
  81.             android:textColor=“#ffffff” />
  82.     </LinearLayout>
  83. </LinearLayout>

依旧很简单,除了图标比较难找以外~~

3、MainActivity

MainActivity的布局文件已经贴过了~~

  1. package com.zhy.demo_zhy_17_drawerlayout;
  2. import android.os.Bundle;
  3. import android.support.v4.app.FragmentActivity;
  4. import android.support.v4.widget.DrawerLayout;
  5. import android.support.v4.widget.DrawerLayout.DrawerListener;
  6. import android.view.Gravity;
  7. import android.view.View;
  8. import android.view.Window;
  9. import com.nineoldandroids.view.ViewHelper;
  10. public class MainActivity extends FragmentActivity
  11. {
  12.     private DrawerLayout mDrawerLayout;
  13.     @Override
  14.     protected void onCreate(Bundle savedInstanceState)
  15.     {
  16.         super.onCreate(savedInstanceState);
  17.         requestWindowFeature(Window.FEATURE_NO_TITLE);
  18.         setContentView(R.layout.activity_main);
  19.         initView();
  20.         initEvents();
  21.     }
  22.     public void OpenRightMenu(View view)
  23.     {
  24.         mDrawerLayout.openDrawer(Gravity.RIGHT);
  25.         mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED,
  26.                 Gravity.RIGHT);
  27.     }
  28.     private void initEvents()
  29.     {
  30.         mDrawerLayout.setDrawerListener(new DrawerListener()
  31.         {
  32.             @Override
  33.             public void onDrawerStateChanged(int newState)
  34.             {
  35.             }
  36.             @Override
  37.             public void onDrawerSlide(View drawerView, float slideOffset)
  38.             {
  39.                 View mContent = mDrawerLayout.getChildAt(0);
  40.                 View mMenu = drawerView;
  41.                 float scale = 1 – slideOffset;
  42.                 float rightScale = 0.8f + scale * 0.2f;
  43.                 if (drawerView.getTag().equals(“LEFT”))
  44.                 {
  45.                     float leftScale = 1 – 0.3f * scale;
  46.                     ViewHelper.setScaleX(mMenu, leftScale);
  47.                     ViewHelper.setScaleY(mMenu, leftScale);
  48.                     ViewHelper.setAlpha(mMenu, 0.6f + 0.4f * (1 – scale));
  49.                     ViewHelper.setTranslationX(mContent,
  50.                             mMenu.getMeasuredWidth() * (1 – scale));
  51.                     ViewHelper.setPivotX(mContent, 0);
  52.                     ViewHelper.setPivotY(mContent,
  53.                             mContent.getMeasuredHeight() / 2);
  54.                     mContent.invalidate();
  55.                     ViewHelper.setScaleX(mContent, rightScale);
  56.                     ViewHelper.setScaleY(mContent, rightScale);
  57.                 } else
  58.                 {
  59.                     ViewHelper.setTranslationX(mContent,
  60.                             -mMenu.getMeasuredWidth() * slideOffset);
  61.                     ViewHelper.setPivotX(mContent, mContent.getMeasuredWidth());
  62.                     ViewHelper.setPivotY(mContent,
  63.                             mContent.getMeasuredHeight() / 2);
  64.                     mContent.invalidate();
  65.                     ViewHelper.setScaleX(mContent, rightScale);
  66.                     ViewHelper.setScaleY(mContent, rightScale);
  67.                 }
  68.             }
  69.             @Override
  70.             public void onDrawerOpened(View drawerView)
  71.             {
  72.             }
  73.             @Override
  74.             public void onDrawerClosed(View drawerView)
  75.             {
  76.                 mDrawerLayout.setDrawerLockMode(
  77.                         DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.RIGHT);
  78.             }
  79.         });
  80.     }
  81.     private void initView()
  82.     {
  83.         mDrawerLayout = (DrawerLayout) findViewById(R.id.id_drawerLayout);
  84.         mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,
  85.                 Gravity.RIGHT);
  86.     }
  87. }

嗯,代码基本没什么注释~~维撒呢?是因为的确没什么好注释的。

提几点:

1、为了模拟QQ的右侧菜单需要点击才能出现,所以在初始化DrawerLayout的时候,使用了mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT);意思是只有编程才能将其弹出。

然后在弹出以后,需要让手势可以滑动回去,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,关于动画各种偏移量、缩放比例的计算请参考Android 高仿 QQ5.0 侧滑菜单效果 自定义控件来袭 基本是一致的,唯一的不同的地方,给Content设置了ViewHelper.setTranslationX(mContent, mMenu.getMeasuredWidth() * (1 – scale));让Content在菜单的右侧,默认情况下Menu在菜单之上,所以我们根据菜单划出的距离给Content设置X方向的偏移量。

好了,其实看到可以这么做,基本上任何的侧滑菜单效果都能写出来了。有兴趣的话,可以拿DrawerLayout实现这篇博客的所有效果:Android 实现形态各异的双向侧滑菜单 自定义控件来袭 。

3、setDrawerListener

通过代码也能看出来,可以使用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判断是通过TAG判断的,我觉得使用gravity应该也能判断出来~~

好了,没撒了,由于DrawerLayout默认只能从边界划出菜单,但是QQ划出菜单的手势区域比较大,大家有兴趣,可以重写Activity的onTouchEvent,在里面判断,如果是左右滑动手势神马的,弹出菜单,应该不麻烦~~~
