Android隐藏状态栏和标题栏，相当于全屏效果

隐藏标题栏需要使用预定义样式：android:theme=”@android:style/Theme.NoTitleBar”. //隐藏标题栏
隐藏状态栏：android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”. //全屏

XML代码：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="de.vogella.android.temperature"      android:versionCode="1"      android:versionName="1.0">    <application android:icon="@drawable/icon" android:label="@string/app_name">        <activity android:name=".Convert"                  android:label="@string/app_name"                   android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>     </application>    <uses-sdk android:minSdkVersion="9" /> </manifest>

JAVA代码：

@Overridepublic void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    // hide titlebar of application    // must be before setting the layout    requestWindowFeature(Window.FEATURE_NO_TITLE);    // hide statusbar of Android    // could also be done later    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,            WindowManager.LayoutParams.FLAG_FULLSCREEN);    setContentView(R.layout.main);    text = (EditText) findViewById(R.id.EditText01); }
