Android隱藏狀態欄和標題欄，相當於全屏效果

隱藏標題欄需要使用預定義樣式：android:theme=”@android:style/Theme.NoTitleBar”.
隱藏狀態欄：android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”.

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"

       package="de.vogella.android.temperature"

[Java]代碼:

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);
