手机屏幕尺寸怎么量 Android APP适配全面屏手机的技术要点(9)

google官方Example中给出了只调一个方法就能实现全屏和非全屏之间切换的思路：

googlesamples/android-ImmersiveMode

具体代码如下：

/** 
 * Detects and toggles immersive mode (also known as "hidey bar" mode). 
 */  
public void toggleHideyBar() {  

    // BEGIN_INCLUDE (get_current_ui_flags)  
    // The UI options currently enabled are represented by a bitfield.  
    // getSystemUiVisibility() gives us that bitfield.  
    int uiOptions = getActivity().getWindow().getDecorView().getSystemUiVisibility();  
    int newUiOptions = uiOptions;  
    // END_INCLUDE (get_current_ui_flags)  
    // BEGIN_INCLUDE (toggle_ui_flags)  
    boolean isImmersiveModeEnabled =  
            ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);  
    if (isImmersiveModeEnabled) {  
        Log.i(TAG, "Turning immersive mode mode off. ");  
    } else {  
        Log.i(TAG, "Turning immersive mode mode on.");  
    }  

    // Navigation bar hiding:  Backwards compatible to ICS.  
    if (Build.VERSION.SDK_INT >= 14) {  
        newUiOptions ^= View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;  
    }  

    // Status bar hiding: Backwards compatible to Jellybean  
    if (Build.VERSION.SDK_INT >= 16) {  
        newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;  
    }  

    // Immersive mode: Backward compatible to KitKat.  
    // Note that this flag doesn't do anything by itself, it only augments the behavior  
    // of HIDE_NAVIGATION and FLAG_FULLSCREEN.  For the purposes of this sample  
    // all three flags are being toggled together.  
    // Note that there are two immersive mode UI flags, one of which is referred to as "sticky".  
    // Sticky immersive mode differs in that it makes the navigation and status bars  
    // semi-transparent, and the UI flag does not get cleared when the user interacts with  
    // the screen.  
    if (Build.VERSION.SDK_INT >= 18) {  
        newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;  
    }  

    getActivity().getWindow().getDecorView().setSystemUiVisibility(newUiOptions);  
    //END_INCLUDE (set_ui_flags)  
}  

关于沉浸式全屏更加详细的使用方法，可以参考google开发者文档：

Using Immersive Full-Screen Mode

以上就是app适配全面屏手机的一个总结。如果客官碰到相关app适配全面屏问题，可以参考上述的一些方法来解决问题，假使能够给带来一些帮助，It is my pleasure。
