1.設定沉浸式狀態列的方法

/**
* true 進入全屏模式，狀態列不顯示
* false 顯示狀態列
*/

public static void setSystemUiVisibility(Activity activity, boolean enterFullscreen) {
        if (activity == null) {
            return;
        }
        View decor = activity.getWindow().getDecorView();
        if (enterFullscreen) {
            activity.getWindow
 
().setFlags(
                    WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);

        } else {
            activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }

        /* place the window within the entire screen, ignoring
         *  decorations around the border (such as the status bar).*/
 

        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            return;
        }
        Window window = activity.getWindow
 
();
        // Translucent status bar
        window.setFlags(
                WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
                WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        // Translucent navigation bar
        window.setFlags(
                WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,
                WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        int systemUiVisibility = decor.getSystemUiVisibility();
        int flags = View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        if (enterFullscreen) {
            systemUiVisibility |= flags;
        } else {
            systemUiVisibility &= ~flags;
        }
        decor.setSystemUiVisibility(systemUiVisibility);
    }


/**
*
*是否進入全屏模式
*
*/
    public static boolean isFullScreenActivity(Activity activity) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            return (activity.getWindow().getAttributes().flags & WindowManager.LayoutParams.FLAG_FULLSCREEN) > 0;
        }
        View decor = activity.getWindow().getDecorView();
        int systemUiVisibility = decor.getSystemUiVisibility();
        int flags = View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        return (systemUiVisibility & flags) == flags;
    }

2.使用Material主題(比較傾向於這種方法)

在BaseActivity中新增下面程式碼

 requestWindowFeature(Window.FEATURE_NO_TITLE);//無標題
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//豎直方向
        this.TAG = getClass().getSimpleName();
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);//軟鍵盤自適應

修改狀態列顏色只有在5.0及以上的版本才會生效，首先檢視styles.xml中是否存在AppTheme：

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->

    </style>

    然後新建values-v19,values-v21檔案，建立styles.xml檔案，新增主題：

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!--狀態列顏色-->
        <item name="android:colorPrimaryDark">@color/colorAccent</item>
        <!--ActionBar顏色-->
        <item name="android:colorPrimary">#ff0</item>
        <!--介面背景顏色-->
        <item name="android:windowBackground">@color/colorAccent</item>
        <!--導航欄顏色-->
        <item name="android:navigationBarColor">#f00</item>
    </style>

最後將Manifest裡面的主題更換為AppTheme就行了。
