Android 高仿QQ5.2雙向側(cè)滑菜單DrawerLayout實(shí)現(xiàn)源代碼

左右側(cè)滑效果圖

1.主頁的實(shí)現(xiàn)

直接將DrawerLayout作為根布局，然后其內(nèi)部第一個View為內(nèi)容區(qū)域，第二個View為左側(cè)菜單，第三個View為右側(cè)側(cè)滑菜單，當(dāng)前第三個是可選的。

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>

代碼

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.左菜單和右菜單布局(左菜單和右菜單的布局和代碼隨便你怎么寫，這里是左菜單的樣例)

<?

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

1、為了模擬QQ的右側(cè)菜單須要點(diǎn)擊才干出現(xiàn)。所以在初始化DrawerLayout的時候，使用了mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT);意思是僅僅有編程才干將其彈出。然后在彈出以后。須要讓手勢能夠滑動回去，所以在OpenRightMenu中又編寫了：mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED,Gravity.RIGHT); UNLOCK了一下。

最后在onDrawerClosed回調(diào)中。繼續(xù)設(shè)置mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT)。

2、動畫效果動畫用了nineoldandroids。

3、setDrawerListener
通過代碼也能看出來，能夠使用setDrawerListener監(jiān)聽菜單的打開與關(guān)閉等等。這里對于當(dāng)前操作是哪個菜單的推斷是通過TAG推斷的。我認(rèn)為使用gravity應(yīng)該也能推斷出來
