Android 抽屉式

之前一直以为Android的抽屉式特别麻烦，今天做了demo，废话不多说了，直接代码。

package com.lizw.menudome;

import android.app.ActionBar;
import android.app.Activity;
import android.content.res.Configuration;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;


public class MainActivity extends Activity {

	private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;
    private Drawable drawerArrow;
    
    ActionBar ab = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ab = getActionBar();
        ab.setDisplayHomeAsUpEnabled(true);
        ab.setDisplayShowHomeEnabled(false);
        ab.setHomeButtonEnabled(true);
//        ab.setDisplayShowCustomEnabled(true);
        ab.setTitle("检测");

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.navdrawer);

        drawerArrow = getResources().getDrawable(R.drawable.ic_drawer);
        
        
		mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,false,R.drawable.ic_drawer, 0, 0) {
			public void onDrawerClosed(View view) {
				super.onDrawerClosed(view);
				invalidateOptionsMenu();
				ab.setTitle("检测中心");
			}

			public void onDrawerOpened(View drawerView) {
				super.onDrawerOpened(drawerView);
				invalidateOptionsMenu();
				ab.setTitle("个人中心");
			}

		};
        
		
        
        mDrawerLayout.setDrawerListener(mDrawerToggle);
        mDrawerToggle.syncState();


        String[] values = new String[]{
            "列表导航",
            "列表导航",
            "列表导航",
            "列表导航"
        };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, android.R.id.text1, values);
        mDrawerList.setAdapter(adapter);
        
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {
            if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
                mDrawerLayout.closeDrawer(mDrawerList);
            } else {
                mDrawerLayout.openDrawer(mDrawerList);
            }
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
