Android完全透明的状态栏?

我搜索了文档，但只找到了这个: 链接。这是用来使酒吧半透明?我想做的是使状态栏完全透明(如下图所示)，并使它向后兼容APK<19:

我的styles.xml:

<resources xmlns:tools="http://schemas.android.com/tools">

  <style name="AppTheme" parent="Theme.AppCompat.Light">
  <item name="android:actionBarStyle">@style/ThemeActionBar</item>
  <item name="android:windowActionBarOverlay">true</item>
  <!-- Support library compatibility -->
  <item name="actionBarStyle">@style/ThemeActionBar</item>
  <item name="windowActionBarOverlay">true</item>
  </style>

  <style name="ThemeActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid">
  <item name="android:background"> @null </item>
  <!-- Support library compatibility -->
  <item name="background">@null</item>
  <item name="android:displayOptions"> showHome | useLogo</item>
  <item name="displayOptions">showHome|useLogo</item>

  </style>

</resources>

我能做的是:

你可以使用下面的代码使状态栏透明。见图片，红色高亮，帮助您识别使用下面的代码

你的android应用程序的Kotlin代码片段

步骤:1在“On create Method”中写下代码

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
}
if (Build.VERSION.SDK_INT >= 19) {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
    window.statusBarColor = Color.TRANSPARENT
}

你需要SetWindowFlag方法，在下面的代码中描述。

private fun setWindowFlag(bits: Int, on: Boolean) {
    val win = window
    val winParams = win.attributes
    if (on) {
        winParams.flags = winParams.flags or bits
    } else {
        winParams.flags = winParams.flags and bits.inv()
    }
    win.attributes = winParams
}

android应用程序的Java代码片段:

Step1:主活动代码

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);
}

Step2: SetWindowFlag方法

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);
}

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);
    }
}

这应该可以

//在Activity的onCreate()中为实例

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);
}

这仅适用于API级别>= 21。这对我很管用。这是我的代码(Kotlin)

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        findViewById<View>(android.R.id.content).systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
}

在顶部布局中使用android:fitsSystemWindows="false"

2017-06-28 00:05:45

下面是kotlin中的一个扩展，它可以做到这一点:

fun Activity.setTransparentStatusBar() {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        window.statusBarColor = Color.TRANSPARENT
    }
}
