兩種方法,第一種是靜態開啟方法
把application 或者 activity的主題設定為Theme.Holo即可
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.baidu.homer" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="18"/> <application android:label="@string/app_name" android:icon="@drawable/ic_launcher" android:theme="@android:style/Theme.Holo"> <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>
第二種是動態開啟
import android.app.ActionBar;import android.app.Activity;import android.drm.DrmStore;import android.os.Bundle;public class MyActivity extends Activity { /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ActionBar actionBar = getActionBar(); actionBar.show(); }}
