【Android】沉浸式状态栏完美解决方案

沉浸式状态栏

现在搜索Android 沉浸式状态栏，真的是一堆一堆，写的特别多，但是真正用的舒服的真没有，在这里自己整理一下开发记录
注意，在使用这个步骤过程之前，请把之前设置的代码注释一下:

• 把布局带有 android:fitsSystemWindows 注释掉
• style文件中凡是在 style.xml 中 有关 windowTranslucentNavigation、windowTranslucentStatus、statusBarColor 也注释掉不要出现

前记声明

-代码需要注释掉·一

// windowTranslucentNavigation、windowTranslucentStatus、statusBarColor注释掉
<style name="IThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

        <!--沉浸式：这里注释掉-->
        <!--<item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>-->
</style>
    

-代码需要注释掉·二

//布局中涉及这句代码的页去掉
android:fitsSystemWindows="true"

}

开始适配，代码引入

---

1.BaseActivity，onCreate方法中设置

在BaseActivity中，onCreate方法中设置，如下代码

BaseActivity.java

	@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//禁止横屏
        mContext = this;
        mActivity = this;
        appContext = getApplicationContext();
        mApplication = getApplication();
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(getLayout());
        //注意绑定要在绑定试图之后写
        mUnbinder = ButterKnife.bind(this);

        setOrientation();
        initEvent();


        //沉浸式代码配置
        //当FitsSystemWindows设置 true 时，会在屏幕最上方预留出状态栏高度的 padding
        StatusBarUtil.setRootViewFitsSystemWindows(this, true);
        //设置状态栏透明
        StatusBarUtil.setTranslucentStatus(this);
        //一般的手机的状态栏文字和图标都是白色的, 可如果你的应用也是纯白色的, 或导致状态栏文字看不清
        //所以如果你是这种情况,请使用以下代码, 设置状态使用深色文字图标风格, 否则你可以选择性注释掉这个if内容
        if (!StatusBarUtil.setStatusBarDarkTheme(this, true)) {
            //如果不支持设置深色风格 为了兼容总不能让状态栏白白的看不清, 于是设置一个状态栏颜色为半透明,
            //这样半透明+白=灰, 状态栏的文字能看得清
            StatusBarUtil.setStatusBarColor(this, 0x55000000);
        }
    }

还可以使用StatusBarUtil.setStatusBarColor(this,颜色值); 设置任何情况下的状态栏颜色

2.MainActivity中的具体使用

MainActivity中的具体使用，简单使用，如下代码

MainActivity.java

public class MainActivity extends BaseActivity implements IMainAView {
    @BindView(R.id.xbanner_banner)
    XBanner xbanner_banner;

    private IMainAPresenter mIMainAPresenter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mIMainAPresenter = new MainAPresenterImpl(this);
        //用来设置整体下移，状态栏沉浸
        StatusBarUtil.setRootViewFitsSystemWindows(this, false);
    }

    @Override
    protected int getLayout() {
        return R.layout.activity_main;
    }

    @Override
    protected void initEvent() {
        final List<String> imageUrl = new ArrayList<>();
        imageUrl.add("http://img1.imgtn.bdimg.com/it/u=3523376988,1285761647&fm=26&gp=0.jpg");
        imageUrl.add("http://img1.imgtn.bdimg.com/it/u=2327449998,3969527717&fm=26&gp=0.jpg");
        imageUrl.add("http://img5.imgtn.bdimg.com/it/u=3436693222,1592947169&fm=26&gp=0.jpg");

        //添加轮播图片数据（图片数据不局限于网络图片、本地资源文件、View 都可以）,刷新数据也是调用该方法
        xbanner_banner.setData(imageUrl, null);//第二个参数为提示文字资源集合
        //加载图片
        xbanner_banner.loadImage(new XBanner.XBannerAdapter() {
            @Override
            public void loadBanner(XBanner banner, Object model, View view, int position) {
                Glide.with(MainActivity.this).load(imageUrl.get(position)).into((ImageView) view);
            }
        });
        xbanner_banner.setOnItemClickListener(new XBanner.OnItemClickListener() {
            @Override
            public void onItemClick(XBanner banner, Object model, View view, int position) {
                Toast.makeText(MainActivity.this, "点击了第：" + position + "个轮播图", Toast.LENGTH_LONG).show();
                switch (position) {
                    case 0://黑色字体
                        StatusBarUtil.setTranslucentStatus(MainActivity.this);//透明状态栏
                        StatusBarUtil.setStatusBarDarkTheme(MainActivity.this, false);
                        break;
                    case 1://白色字体
                        StatusBarUtil.setStatusBarDarkTheme(MainActivity.this, true);
                        break;
                    case 2:
                        //设置白色字体，其他背景
                        StatusBarUtil.setStatusBarDarkTheme(MainActivity.this, false);
                        StatusBarUtil.setStatusBarColor(MainActivity.this, Color.parseColor("#58C087"));//设置背景颜色
                        //
                        break;
                }
            }
        });
    }

    @Override
    public <T> T request(int requestFlag) {
        return null;
    }

    @Override
    public <T> void response(T response, int responseFlag) {

    }
}

---

以上步骤就可以满足：

• 沉浸式状态栏
• 透明状态栏
• 设置状态栏背景颜色
• 设置状态栏字体颜色
• …
• 这样可以在任何情况下改变状态栏颜色，或者设置透明

---

图片示例

图片示例： 沉浸式，沉浸式透明状态栏，可以设置状态栏背景，设置状态栏文字颜色
