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

</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
