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" >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/qq" >

        <Button
            android: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>

    <fragment
        android: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" />

    <fragment
        android: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;

	@Override
	protected 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() {

			@Override
			public void onDrawerSlide(View drawerView, float slideOffset) {
				// TODO Auto-generated method stub
				View 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);
				}
			}

			@Override
			public void onDrawerOpened(View drawerView) {
				// TODO Auto-generated method stub

			}

			@Override
			public void onDrawerClosed(View drawerView) {
				// TODO Auto-generated method stub
				mDrawerLayout.setDrawerLockMode(
						DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.RIGHT);
			}

			@Override
			public 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)

</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
