以编程方式在Android中制作应用程序FULL SCREEN

Question

我知道应用程序可以通过活动清单中的标签全屏显示android:theme="@android:style/Theme.NoTitleBar.Fullscreen"是否可以通过编程方式从应用程序内切换到全屏模式？

Answer 1

添加两行......

requestWindowFeature(Window.FEATURE_NO_TITLE); 
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);

Answer 2

您可以创建新样式并添加

<item name="android:windowFullscreen">true</item>

或者您可以以编程方式执行此操作:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 3

在setContentView之前在Activity onCreate中添加它:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // remove title
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.main);
}

并在AndroidManifest.xml文件中:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
</activity>
