Android：UI控件DrawerLayout、Fragment、SlidingLayout、侧滑菜单

DrawerLayout与Fragment的联用

1.xml代码

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <FrameLayout
        android:id="@+id/fragment_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>
    <RelativeLayout
        android:id="@+id/menu_layout"
        android:layout_width="300dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="#ff333333">
        <ListView
            android:id="@+id/menu_listView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
        </ListView>
    </RelativeLayout>
</android.support.v4.widget.DrawerLayout>

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<String>(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);
            ft.commit();
                            
            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;
    }
}
