1.xml代码
xmlns:android="/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
android:id="@+id/fragment_layout"
android:layout_width="match_parent"

android:layout_width="match_parent"

2.MainActivity继承FragmentActivity
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.AdapterView.OnItemClickListener;
public class MainActivity extends FragmentActivity
{
/*
* DrawerLayout与Fragment的联用
* DrawerLayout相关：
* 1.一般内容层使用framelayout
* 2.slidingLayout需要设置一个layout_grative属性
* 文档建议使用android:layout_gravity="start"
*/
public static final String[] TITLES =
{ "Henry IV (1)", "Henry V", "Henry VIII", "Richard II", "Richard III", "Merchant of Venice", "Othello", "King Lear" };
private DrawerLayout mDrawer_layout;
private RelativeLayout mMenu_layout;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawer_layout = (DrawerLayout) findViewById(R.id.drawer_layout);
mMenu_layout = (RelativeLayout) findViewById(R.id.menu_layout);
ListView menu_listview = (ListView) mMenu_layout.findViewById(R.id.menu_listView);
menu_listview.setAdapter(new ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, TITLES));
//监听菜单
menu_listview.setOnItemClickListener(new DrawerItemClickListener());
}
public class DrawerItemClickListener implements OnItemClickListener
{
@Override
public void onItemClick(AdapterView> parent, View view, int position, long id)
{
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
Fragment fragment = null;
//根据item点击行号判断启用哪个Fragment
switch (position)
{
case 0:
fragment = new FirstFragment();
break;
case 1:
fragment = new NextFragment();
break;
default:
break;
}
ft.replace(R.id.fragment_layout, fragment);
mit();
mDrawer_layout.closeDrawer(mMenu_layout);//点击后关闭mMenu_layout
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
3.Fragment类
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FirstFragment extends Fragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View layout = inflater.inflate(R.layout.firstlayout, null);
return layout;
}
}
public class NextFragment extends Fragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View layout = inflater.inflate(R.layout.nextlayout, null);
return layout;
}
}
