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" > <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" 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
