Android Studio 全屏沉浸式透明状态栏效果

如何实现?

 1.)首先实现全屏

 第一种:继承主题特定主题

 在Android API 19以上可以使用****.TranslucentDecor***有关的主题,自带相应半透明效果,Theme.Holo.NoActionBar.TranslucentDecor和Theme.Holo.Light.NoActionBar.TranslucentDecor两种主题为新增加的,所以要新建values-v19文件夹并创建styles文件添加如下代码

<style name="AppBaseTheme" parent="android:Theme.Holo.Light.NoActionBar.TranslucentDecor">
        <!-- Customize your theme here. -->
</style>

第二种:在activity中采用代码的方式

Android 4.4以上可以添加如下代码

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//透明状态栏
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//透明导航栏
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}

Android 5.0 以上也可以使用下面的代码实现全屏

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}

2.)解决状态栏占位问题

第一种:主题添加如下设置

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

第二种:activity layout根目录添加下面代码

android:fitsSystemWindows="true"

第三种:通过Java代码设置

rootview.setFitsSystemWindows(true);

 3.)状态栏导航栏设置背景色

4.4以上的可以采用修改contentView的背景色,或者动态添加一个view到contentView上

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    //透明状态栏
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    //透明导航栏
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
    //设置contentview为fitsSystemWindows
    ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content);
    View childAt = contentView.getChildAt(0);
    if (childAt != null) {
      childAt.setFitsSystemWindows(true);
    }
    //给statusbar着色
    View view = new View(this);
    view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this)));
    view.setBackgroundColor(color);
    contentView.addView(view);
}

  

动态获取StatusBarHeight函数如下

/**
     * 获取状态栏高度
     *
     * @param context context
     * @return 状态栏高度
     */
    private static int getStatusBarHeight(Context context) {
        // 获得状态栏高度
        int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
        return context.getResources().getDimensionPixelSize(resourceId);
    }

 

动态获取NavigationBarHeight函数如下

/**
     * 获取导航栏高度
     *
     * @param context context
     * @return 导航栏高度
     */
    public static int getNavigationBarHeight(Context context) {
        int resourceId = context.getResources().getIdentifier("navigation_bar_height", "dimen", "android");
        return context.getResources().getDimensionPixelSize(resourceId);
    }

4.)贴出整体java代码实现方式

private void initWindows() {
        Window window = getWindow();
        int color = getResources().getColor(R.color.wechatBgColor);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            //设置状态栏颜色
            window.setStatusBarColor(color);
            //设置导航栏颜色
            window.setNavigationBarColor(getResources().getColor(R.color.footerBgColor));
            ViewGroup contentView = ((ViewGroup) findViewById(android.R.id.content));
            View childAt = contentView.getChildAt(0);
            if (childAt != null) {
                childAt.setFitsSystemWindows(true);
            }
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            //透明状态栏
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            //透明导航栏
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            //设置contentview为fitsSystemWindows
            ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content);
            View childAt = contentView.getChildAt(0);
            if (childAt != null) {
                childAt.setFitsSystemWindows(true);
            }
            //给statusbar着色
            View view = new View(this);
            view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this)));
            view.setBackgroundColor(color);
            contentView.addView(view);
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && useStatusBarColor) {//android6.0以后可以对状态栏文字颜色和图标进行修改
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
        }
    }
