在setContentView()之前将这些行添加到您的活动中

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Window w = getWindow();
    w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

添加这2行到你的AppTheme

<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>

最后一件事你的思想sdkversion必须是19

minSdkVersion 19

我刚在这里找到的

因为它已经经过了6年，默认的minSDKAPI是21(棒棒糖)*CMIIW。下面是我总结透明状态栏并且不与导航按钮重叠的方法:

fun setStatusBarTransparent(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                rightMargin = inset.right
                topMargin = 0
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

要再次显示状态栏只需要做一些更改:

fun setStatusBarShown(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            val inset1 = windowInset.getInsets(WindowInsetsCompat.Type.statusBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                topMargin = inset1.top
                rightMargin = inset.right
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

我把这个函数放在对象类称为UiUtils，所以当我在我的活动调用该函数(我使用视图绑定太)。它看起来是这样的:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    ...
    UiUtils.setStatusBarTransparent(this, bind.root)
    ...
}

希望我的回答能帮助到你们:)

简单明了，适用于几乎所有用例(API级别16及以上):

在你的应用主题中使用下面的标签使状态栏透明: <项目名称= " android: statusBarColor " > @android:颜色/透明> < /项目 然后在你的活动的onCreate方法中使用这段代码。 查看decorView = getWindow().getDecorView(); decorView.setSystemUiVisibility (View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

这就是你所需要做的一切;)

您可以从开发人员文档中了解更多信息。我也推荐你阅读这篇博文。

芬兰湾的科特林代码:

    val decorView = window.decorView
    decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)

看看我的另一个答案

我发现摆弄styles.xml和activity太麻烦了，因此创建了一个通用的实用工具方法，它有以下选项集

Java

Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);

Kotlin DSL

activity.window.apply {
    clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    statusBarColor = Color.TRANSPARENT
}

这就是实现透明状态栏所需要的全部内容。希望这能有所帮助。

你只需要进入mainactivity。java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Window g = getWindow();
        g.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

        setContentView(R.layout.activity_main);

    }

下面的代码将创建一个完全透明的状态栏:

package com.demo;

import android.app.Activity;
import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
            setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
        }
        if (Build.VERSION.SDK_INT >= 19) {
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        }
        if (Build.VERSION.SDK_INT >= 21) {
            setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
            getWindow().setStatusBarColor(Color.TRANSPARENT);
        }
    }

    public static void setWindowFlag(Activity activity, final int bits, boolean on) {
        Window win = activity.getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }
}
