Android 高仿QQ5.2双向侧滑菜单DrawerLayout实现源码

Android 高仿QQ5.2双向侧滑菜单DrawerLayout实现源码

左右侧滑效果图





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为左侧菜单，第三个View为右侧侧滑菜单，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，这里是左菜单的例子)

<?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" >

android:textColor="#f0f0f0"
android:textSize="20sp" />
</RelativeLayout>

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >

<ImageView

</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，

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
