Android五種隱藏狀態欄和標題欄的方法
方法一：
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 隱藏標題欄 requestWindowFeature(Window.FEATURE_NO_TITLE); // 隱藏狀態欄 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_main); } } 方法二：
<!-- 同時隱藏狀態欄和標題欄 --> <activity android:name="com.ysj.demo.MainActivity" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
方法三：
<!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <!-- 隱藏狀態欄 --> <item name="android:windowFullscreen">true</item> <!-- 隱藏標題欄 --> <item name="android:windowNoTitle">true</item> </style>
方法四：動態顯示隱藏狀態欄
//隱藏狀態欄 WindowManager.LayoutParams lp = context.getWindow().getAttributes(); lp.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; context.getWindow().setAttributes(lp);
//顯示狀態欄 WindowManager.LayoutParams attr = context.getWindow().getAttributes(); attr.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); context.getWindow().setAttributes(attr);
方法五：動態顯示隱藏狀態欄
View類提供了setSystemUiVisibility和getSystemUiVisibility方法，這兩個方法實現對狀態欄的動態顯示或隱藏的操作，以及獲取狀態欄當前可見性。
setSystemUiVisibility方法傳入的實參分析：
setSystemUiVisibility(int visibility)方法可傳入的實參為：
1. View.SYSTEM_UI_FLAG_VISIBLE：顯示狀態欄，
Activity不全屏顯示(恢復到有狀態的正常情況)。
2. View.INVISIBLE：隱藏狀態欄，同時Activity會伸展全屏顯示。
3. View.SYSTEM_UI_FLAG_FULLSCREEN：Activity全屏顯示，且狀態欄被隱藏覆蓋掉。
4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN：Activity全屏顯示，但狀態欄不會被隱藏覆蓋，狀態欄依然可見，Activity頂端布局部分會被狀態遮住。
5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
6. View.SYSTEM_UI_LAYOUT_FLAGS：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION：隱藏虛擬按鍵(導航欄)。有些手機會用虛擬按鍵來代替物理按鍵。
8. View.SYSTEM_UI_FLAG_LOW_PROFILE：狀態欄顯示處于低能顯示狀態(low profile模式)，狀態欄上一些圖標顯示會被隱藏。
