prima cosa, assicurarsi di aggiornare al più recente SDK. Crea un nuovo progetto in Android Studio, quindi aggiungi le librerie appcompat-v7.21.0. + E appcompat-v4.21.0. + Nel tuo buid.gradle come dipendenza gradle.
compile 'com.android.support:appcompat-v7:21.0.2'
compile 'com.android.support:support-v4:21.0.2'
Aggiungi primaryColor e primarycolorDark nel file color.xml.
<resources>
<color name="primaryColor">#2196F3</color>
<color name="primaryColorDark">#0D47A1</color>
</resources>
Aggiungi cassetto apri/chiudi il valore stringa nel file strings.xml.
<resources>
<string name="app_name">Lollipop Drawer</string>
<string name="action_settings">Settings</string>
<string name="drawer_open">open</string>
<string name="drawer_close">close</string>
</resources>
Il file di layout activity_my.xml assomiglia a questo:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include layout="@layout/toolbar" />
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:id="@+id/drawerLayout"
android:layout_height="match_parent">
<!-- activity view -->
<RelativeLayout
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<TextView
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:textColor="#000"
android:text="Activity Content"
android:layout_height="wrap_content" />
</RelativeLayout>
<!-- navigation drawer -->
<RelativeLayout
android:layout_gravity="left|start"
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<ListView
android:id="@+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#eee"
android:background="#fff"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
Il file di layout toolbar.xml si presenta così:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.Toolbar>
tuo MyActivity.java assomiglia a questo: Qui la tua attività deve estendere ActionBarActivity e impostare la barra degli strumenti come barra di azione di supporto.
import android.content.res.Configuration;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

import android.widget.ListView;
public class MyActivity extends ActionBarActivity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
nitView();
if (toolbar != null) {
toolbar.setTitle("Navigation Drawer");
setSupportActionBar(toolbar);
}
initDrawer();
}
private void nitView() {
leftDrawerList = (ListView) findViewById(R.id.left_drawer);

navigationDrawerAdapter=new ArrayAdapter<String>(MyActivity.this, android.R.layout.simple_list_item_1, leftSliderData);
leftDrawerList.setAdapter(navigationDrawerAdapter);
}
private void initDrawer() {
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawerLayout.setDrawerListener(drawerToggle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
if (drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Creare file di style.xml nella cartella valori-21 per Android Lollipop
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="myAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/primaryColor</item>
<item name="colorPrimaryDark">@color/primaryColorDark</item>
<item name="android:statusBarColor">@color/primaryColorDark</item>
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">@android:color/black</item>
</style>
</resources>
creare il file nella cartella style.xml valori per le versioni precedenti, allora Android Lollipop
<resources>
<style name="myAppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">@color/primaryColor</item>
<item name="colorPrimaryDark">@color/primaryColorDark</item>
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">@android:color/black</item>
</style>
</resources>
tuo AndroidManifest.xml è simile a questa:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="nkdroid.com.lollipopdrawer" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/myAppTheme" >
<activity
android:name=".MyActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Sì, lo è, e basta usare ActionBarDrawerToggle da appcompat-V7 (non quello vecchio da supporto-v4) con l'indicatore di default su. – alanv
