实现状态栏全沉浸以及兼容低版本半透明沉浸

来源：互联网发布：html编程语言编辑：程序博客网时间：2024/05/23 02:00

下面是java代码：

public class MainActivity extends Activity {
@SuppressLint("InlinedApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

                getWindow().requestFeature(Window.FEATURE_NO_TITLE);
//判断系统版本是否高于andoroid 5.0 LOLLIPOP
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
//状态栏全透明
Window window = getWindow();
                    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);
                    window.setStatusBarColor(Color.TRANSPARENT);
                    window.setNavigationBarColor(Color.TRANSPARENT);
                }else{
//透明状态栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//透明导航栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
                }

        setContentView(R.layout.activity_main);

//        //透明状态栏
//        getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//        //透明导航栏
//        getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}

注意，在布局文件中，需要将顶部空间属性加上如下内容（粗体部分）：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
tools:context=".MainActivity">

<TextView
android:fitsSystemWindows="true"
android:clipToPadding="true"

android:background="@drawable/sign_background"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#ffffff"
android:textSize="22sp"
android:textStyle="bold"
android:text=" Title_bar" />
