DrawerLayout手势打开侧边栏

首先，来看看布局文件：
acivity_main.xml
http://schemas.android.com/apk/res/android "
    android:id="@+id/main_layout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

   
        android:id="@+id/main_content"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
   
   
   
        android:id="@+id/left_drawer"
        android:layout_width="150dp"
        android:background="@android:color/background_dark"
        android:layout_height="fill_parent"
        android:layout_gravity="start" />


再来看看Activiy中的内容：
public class MainActivity extends FragmentActivity {
public DrawerLayout drawerLayout;// 侧边栏布局
public ListView leftList;// 侧边栏内的选项
public ArrayAdapter arrayAdapter;
private String[] items;
@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  initViews();
}
// 初始化控件
private void initViews() {
  drawerLayout = (DrawerLayout) findViewById(R.id.main_layout);
  items = getResources().getStringArray(R.array.left_array);
  leftList = (ListView) findViewById(R.id.left_drawer);
  arrayAdapter = new ArrayAdapter(this, R.layout.list_item, items);
  leftList.setAdapter(arrayAdapter);
  leftList.setOnItemClickListener(itemListener);
  initFragments();
}
// 添加碎片
private void initFragments() {
  FragmentManager manager = getSupportFragmentManager();
  FragmentTransaction transaction = manager.beginTransaction();
  DrawerFragment fragment = new DrawerFragment();
  // 设置在fragment中按钮来控制侧边栏的打开
  fragment.setDrawerLayout(drawerLayout, leftList);
  transaction.add(R.id.main_content, fragment);
  transaction.commit();
}
// 选项点击事件
OnItemClickListener itemListener = new OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView arg0, View view, int position,
    long arg3) {
   // TODO Auto-generated method stub
   // 设置Activity的标题，这里只是用来做一个测试，你可以在这里用来处理单击侧边栏的选项事件
   setTitle(items[position]);
   // 关闭侧边栏
   drawerLayout.closeDrawer(leftList);
   Log.i("onItemSelected",
     "open?:" + drawerLayout.isDrawerOpen(leftList));
  }
};
/*
  * (non-Javadoc)
  * 
  *  @See  android.support.v4.app.FragmentActivity#onKeyDown(int,
  * android.view.KeyEvent)
  */
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
  // TODO Auto-generated method stub
  // 使用menu键打开或关闭侧边栏
  if (keyCode == KeyEvent.KEYCODE_MENU) {
   if (drawerLayout.isDrawerOpen(leftList)) {
    drawerLayout.closeDrawer(leftList);
   } else {
    drawerLayout.openDrawer(leftList);
   }
  }
  return super.onKeyDown(keyCode, event);
}
}

还有内容填充的片段代码：

public class DrawerFragment extends Fragment implements OnClickListener {
public DrawerLayout layout;
public View view;
public DrawerFragment() {
  super();
  // TODO Auto-generated constructor stub
}
public void setDrawerLayout(DrawerLayout layout, View view) {
  this.layout = layout;
  this.view = view;
}
/*
  * (non-Javadoc)
  * 
  * @see
  * android.support.v4.app.Fragment#onCreateView(android.view.LayoutInflater
  * , android.view.ViewGroup, android.os.Bundle)
  */
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
   Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  View rootView = inflater.inflate(R.layout.fragment_layout, container,
    false);
  Button openBtn = (Button) rootView.findViewById(R.id.open);
  openBtn.setOnClickListener(this);
  return rootView;
}
/*
  * (non-Javadoc)
  * 
  * @see android.view.View.OnClickListener#onClick(android.view.View)
  */
@Override
public void onClick(View v) {
  // TODO Auto-generated method stub
  if (v.getId() == R.id.open) {
   //打开侧边栏
   if (!layout.isDrawerOpen(view)) {
    layout.openDrawer(view);
   }
  }
}
}

使用方法还是很简单的，在关键部分我都有注释。
具体的使用效果图如下：
