Android側滑菜單DrawerLayout的使用

現在側滑菜單使用很多，大都是通過SlidingMenu實作。現在也可以通過DrawerLayout

建立抽屜布局

frament_content.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="25sp" />

</LinearLayout>
           

activity_main.xml

<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" >

    <!-- The main content view -->

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>

    <!-- The navigation view -->

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#ffffcc"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" >
    </ListView>

</android.support.v4.widget.DrawerLayout>
           

需要注意的是，在DrawerLayout中，從左側開始使用 android:layout_gravity="start" ，從右側開始，使用 android:layout_gravity="end"

然後建立一個類繼承Fragment類

/**
 * ContentFragment.java
 * 版權所有(C) 2015
 * 建立者:cuiran 2015-1-3 下午3:25:44
 */
package com.cayden.drawerlayoutdemo;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

/**
 * TODO 
 * @author cuiran
 * @version 1.0.0
 */
public class ContentFragment extends Fragment {

	private TextView textView;
	
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View view = inflater.inflate(R.layout.fragment_content, container, false);
		textView = (TextView) view.findViewById(R.id.textView);
		
		String text = getArguments().getString("text");
		textView.setText(text);
		
		return view;
	}
	
}
           

完成Activity代碼

package com.cayden.drawerlayoutdemo;

import java.util.ArrayList;

import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.content.Intent;
import android.content.res.Configuration;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;


public class MainActivity extends Activity implements OnItemClickListener {

	private DrawerLayout mDrawerLayout;
	private ListView mDrawerList;
	private ArrayList<String> menuLists;
	private ArrayAdapter<String> adapter;
	private ActionBarDrawerToggle mDrawerToggle;
	private String mTitle;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		mTitle = (String) getTitle();

		mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
		mDrawerList = (ListView) findViewById(R.id.left_drawer);
		menuLists = new ArrayList<String>();
		for (int i = 0; i < 5; i++)
			menuLists.add("菜單0" + i);
		adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_1, menuLists);
		mDrawerList.setAdapter(adapter);
		mDrawerList.setOnItemClickListener(this);

		mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
				R.drawable.ic_drawer, R.string.drawer_open,
				R.string.drawer_close) {
			@Override
			public void onDrawerOpened(View drawerView) {
				super.onDrawerOpened(drawerView);
				getActionBar().setTitle("請選擇");
				invalidateOptionsMenu(); // Call onPrepareOptionsMenu()
			}

			@Override
			public void onDrawerClosed(View drawerView) {
				super.onDrawerClosed(drawerView);
				getActionBar().setTitle(mTitle);
				invalidateOptionsMenu();
			}
		};
		mDrawerLayout.setDrawerListener(mDrawerToggle);
		
		//開啟ActionBar上APP ICON的功能
		getActionBar().setDisplayHomeAsUpEnabled(true);
		getActionBar().setHomeButtonEnabled(true);

	}

	@Override
	public boolean onPrepareOptionsMenu(Menu menu) {
		boolean isDrawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
		menu.findItem(R.id.action_websearch).setVisible(!isDrawerOpen);
		return super.onPrepareOptionsMenu(menu);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		//将ActionBar上的圖示與Drawer結合起來
		if (mDrawerToggle.onOptionsItemSelected(item)){
			return true;
		}
		switch (item.getItemId()) {
		case R.id.action_websearch:
			Intent intent = new Intent();
			intent.setAction("android.intent.action.VIEW");
			Uri uri = Uri.parse("http://www.baidu.com");
			intent.setData(uri);
			startActivity(intent);
			break;
		}
		return super.onOptionsItemSelected(item);
	}
	
	@Override
	protected void onPostCreate(Bundle savedInstanceState) {
		super.onPostCreate(savedInstanceState);
		//需要将ActionDrawerToggle與DrawerLayout的狀态同步
		//将ActionBarDrawerToggle中的drawer圖示，設定為ActionBar中的Home-Button的Icon
		mDrawerToggle.syncState();
	}
	
	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		mDrawerToggle.onConfigurationChanged(newConfig);
	}
	
	
	
	
	
	
	

	@Override
	public void onItemClick(AdapterView<?> arg0, View arg1, int position,
			long arg3) {
		// 動态插入一個Fragment到FrameLayout當中
		Fragment contentFragment = new ContentFragment();
		Bundle args = new Bundle();
		args.putString("text", menuLists.get(position));
		contentFragment.setArguments(args);

		FragmentManager fm = getFragmentManager();
		fm.beginTransaction().replace(R.id.content_frame, contentFragment)
				.commit();

		mDrawerLayout.closeDrawer(mDrawerList);
	}
