Android 抽屉效果的导航菜单实现

發(fā)布時(shí)間:2025/6/15 Android 19 豆豆
生活随笔 收集整理的這篇文章主要介紹了 Android 抽屉效果的导航菜单实现 小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

抽屜效果的導(dǎo)航菜單

  看了很多應(yīng)用,覺(jué)得這種側(cè)滑的抽屜效果的菜單很好。

  不用切換到另一個(gè)頁(yè)面,也不用去按菜單的硬件按鈕,直接在界面上一個(gè)按鈕點(diǎn)擊,菜單就滑出來(lái),而且感覺(jué)能放很多東西。

?

  關(guān)于實(shí)現(xiàn),搜索了一下,有如下兩種:

  1.用SlidingDrawer:

  http://developer.android.com/reference/android/widget/SlidingDrawer.html

  但是不知道為什么這個(gè)類官方不建議再繼續(xù)用了:

  Deprecated since API level 17

  2.用DrawerLayout:

  http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html

  Guide在這里:

  http://developer.android.com/training/implementing-navigation/nav-drawer.html

?

庫(kù)的引用

?  首先,?DrawerLayout這個(gè)類是在Support Library里的,需要加上android-support-v4.jar這個(gè)包。

  然后程序中用時(shí)在前面導(dǎo)入import android.support.v4.widget.DrawerLayout;

  如果找不到這個(gè)類,首先用SDK Manager更新一下Android Support Library,然后在Android SDK\extras\android\support\v4路徑下找到android-support-v4.jar,復(fù)制到項(xiàng)目的libs路徑,將其Add to Build Path.

代碼1

  布局:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent" ><android.support.v4.widget.DrawerLayoutxmlns: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 --><!-- main content must be the first element of DrawerLayout because it will be drawn first and drawer must be on top of it --><FrameLayoutandroid:id="@+id/content_frame"android:layout_width="match_parent"android:layout_height="match_parent" /><!-- The navigation drawer --><ListViewandroid:id="@+id/left_drawer"android:layout_width="240dp"android:layout_height="match_parent"android:layout_gravity="left"android:background="#111"android:choiceMode="singleChoice"android:divider="@android:color/transparent"android:dividerHeight="0dp" /></android.support.v4.widget.DrawerLayout></RelativeLayout>

? 

  DrawerLayout的第一個(gè)子元素是主要內(nèi)容,即抽屜沒(méi)有打開(kāi)時(shí)顯示的布局。這里采用了一個(gè)FrameLayout,里面什么也沒(méi)放。

  DrawerLayout的第二個(gè)子元素是抽屜中的內(nèi)容,即抽屜布局,這里采用了一個(gè)ListView。

  主要的Activity(從官方實(shí)例中扒出來(lái)的):

?

package com.example.hellodrawer;import android.os.Bundle; import android.app.Activity; import android.content.res.Configuration; 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; import android.support.v4.app.ActionBarDrawerToggle; import android.support.v4.view.GravityCompat; import android.support.v4.widget.DrawerLayout;public class HelloDrawerActivity extends Activity {private String[] mPlanetTitles;private DrawerLayout mDrawerLayout;private ActionBarDrawerToggle mDrawerToggle;private ListView mDrawerList;@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_hello_drawer);mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);// init the ListView and Adapter, nothing new initListView();// set a custom shadow that overlays the main content when the drawer// opens mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,GravityCompat.START);mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,R.drawable.ic_drawer, R.string.drawer_open,R.string.drawer_close){/** Called when a drawer has settled in a completely closed state. */public void onDrawerClosed(View view){invalidateOptionsMenu(); // creates call to// onPrepareOptionsMenu() }/** Called when a drawer has settled in a completely open state. */public void onDrawerOpened(View drawerView){invalidateOptionsMenu(); // creates call to// onPrepareOptionsMenu() }};// Set the drawer toggle as the DrawerListener mDrawerLayout.setDrawerListener(mDrawerToggle);// enable ActionBar app icon to behave as action to toggle nav drawergetActionBar().setDisplayHomeAsUpEnabled(true);// getActionBar().setHomeButtonEnabled(true);// Note: getActionBar() Added in API level 11 }private void initListView(){mDrawerList = (ListView) findViewById(R.id.left_drawer);mPlanetTitles = getResources().getStringArray(R.array.planets_array);// Set the adapter for the list viewmDrawerList.setAdapter(new ArrayAdapter<String>(this,R.layout.list_item, mPlanetTitles));// Set the list's click listenermDrawerList.setOnItemClickListener(new OnItemClickListener(){@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id){// Highlight the selected item, update the title, and close the// drawermDrawerList.setItemChecked(position, true);setTitle(mPlanetTitles[position]);mDrawerLayout.closeDrawer(mDrawerList);}});}@Overrideprotected void onPostCreate(Bundle savedInstanceState){super.onPostCreate(savedInstanceState);// Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState();}@Overridepublic void onConfigurationChanged(Configuration newConfig){super.onConfigurationChanged(newConfig);mDrawerToggle.onConfigurationChanged(newConfig);}@Overridepublic boolean onOptionsItemSelected(MenuItem item){// Pass the event to ActionBarDrawerToggle, if it returns// true, then it has handled the app icon touch eventif (mDrawerToggle.onOptionsItemSelected(item)){return true;}// Handle your other action bar items...return super.onOptionsItemSelected(item);}}

  比較糾結(jié)的是用了Level 11的一個(gè)API,這樣minSdkVersion就有限制,不能太低。

  圖片資源Android官網(wǎng)示例處提供下載了。

  程序運(yùn)行后效果如下:

  

  抽屜打開(kāi)前:

  抽屜打開(kāi)后:

代碼2

  今天又看了一下DrawerLayout的類,發(fā)現(xiàn)有很多方法可以直接用的。

  重新試了一下,其實(shí)不用上面那么麻煩,隨便自己定義一個(gè)按鈕控制抽屜的打開(kāi)就行:

  布局:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:paddingBottom="@dimen/activity_vertical_margin"android:paddingLeft="@dimen/activity_horizontal_margin"android:paddingRight="@dimen/activity_horizontal_margin"android:paddingTop="@dimen/activity_vertical_margin"tools:context=".DrawerActivity" ><android.support.v4.widget.DrawerLayoutandroid:id="@+id/drawer_layout"android:layout_width="match_parent"android:layout_height="match_parent" ><!-- The main content view --><FrameLayoutandroid:id="@+id/content_frame"android:layout_width="match_parent"android:layout_height="match_parent" ><Buttonandroid:id="@+id/btn"android:layout_width="match_parent"android:layout_height="wrap_content"android:text="open" /></FrameLayout><!-- The navigation drawer --><ListViewandroid:id="@+id/left_drawer"android:layout_width="240dp"android:layout_height="match_parent"android:layout_gravity="start"android:background="#111"android:choiceMode="singleChoice"android:divider="@android:color/transparent"android:dividerHeight="0dp" /></android.support.v4.widget.DrawerLayout></RelativeLayout>

?

  主要代碼:

package com.example.hellodrawer;import android.os.Bundle; import android.app.Activity; import android.support.v4.widget.DrawerLayout; import android.view.Gravity; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button;public class DrawerActivity extends Activity {private DrawerLayout mDrawerLayout = null;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_drawer);mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);Button button = (Button) findViewById(R.id.btn);button.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v){// 按鈕按下,將抽屜打開(kāi) mDrawerLayout.openDrawer(Gravity.LEFT);}});}}
