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

隐藏状态栏：android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”.

<"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>

@Override public 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); }
