如何使用drawerlayout

参考博客:http://blog.csdn.net/lmj623565791/article/details/41531475/

今天给简单的介绍下如何去使用DrawerLayout这个控件
首先是布局：

<?xml version="1.0" encoding="utf-8"?><android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:id="@+id/drawerlayout"    android:layout_height="match_parent"    android:background="@android:color/holo_orange_light"    tools:context="com.mag.administrator.drawerlayoutdemo.MainActivity">    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="@drawable/idlefish">    </RelativeLayout>    <fragment        android:id="@+id/left_menu"        android:name="com.mag.administrator.drawerlayoutdemo.MenuLeftFragment"        android:layout_width="200dp"        android:layout_height="match_parent"        android:layout_gravity="left"        android:tag="LEFT" /></android.support.v4.widget.DrawerLayout>这是MainActivity中的代码

private DrawerLayout drawerlayout;

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    //初始化视图    initView();    //设置监听    setListener();}private void setListener() {    drawerlayout.addDrawerListener(new DrawerLayout.DrawerListener() {        @Override        public void onDrawerSlide(View drawerView, float slideOffset) {            //获取第一个子View,就是            View mContentView = drawerlayout.getChildAt(0);            float scale = 1 - slideOffset;            float rightScale = 0.8f + scale * 0.2f;            if (drawerView.getTag().equals("LEFT")) {                float leftScale = 1 - 0.3f * scale;                ViewHelper.setScaleX(drawerView, leftScale);                ViewHelper.setScaleY(drawerView, leftScale);                ViewHelper.setAlpha(drawerView, 0.6f + 0.4f * (1 - scale));                ViewHelper.setTranslationX(mContentView,                        drawerView.getMeasuredWidth() * (1 - scale));                ViewHelper.setPivotX(mContentView, 0);                ViewHelper.setPivotY(mContentView,                        mContentView.getMeasuredHeight() / 2);                mContentView.invalidate();                ViewHelper.setScaleX(mContentView, rightScale);                ViewHelper.setScaleY(mContentView, rightScale);            }        }        @Override        public void onDrawerOpened(View drawerView) {        }        @Override        public void onDrawerClosed(View drawerView) {        }        @Override        public void onDrawerStateChanged(int newState) {        }    });}private void initView() {    drawerlayout = (DrawerLayout) findViewById(R.id.drawerlayout);    // 设置模式    drawerlayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.RIGHT);}

然后写上继承Fragment的类

     @Override            public View onCreateView(LayoutInflater inflater, ViewGroup container,                                     Bundle savedInstanceState)            {                return inflater.inflate(R.layout.layout_menu, container, false);            }

布局文件：

<?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:orientation="vertical">    <TextView        android:id="@+id/tv_one"        android:layout_width="150dp"        android:layout_height="50dp"        android:layout_centerInParent="true"        android:gravity="center"        android:text="itemone"        android:textSize="20sp" />    <TextView        android:layout_width="150dp"        android:layout_height="50dp"        android:layout_below="@id/tv_one"        android:layout_centerInParent="true"        android:gravity="center"        android:text="itemtwo"        android:textSize="20sp" /></RelativeLayout>

这样就完成了。是不是很简单。
