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:
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:)
这是一个简单的方法，我找到了很多搜索。
步骤1
在你的主题里放这个项目
<item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>
步骤2
主要活动
WindowCompat.setDecorFitsSystemWindows(window, false)
非常重要，如果你使用底部导航栏
在一些设备中，API 30+ u会发现系统导航栏与底部导航栏重叠，如果在你的应用中使用它。
这就解决了这个问题。
if (Build.VERSION.SDK_INT >= 30) {
// Root ViewGroup of my activity
val root = findViewById<ConstraintLayout>(R.id.root)
ViewCompat.setOnApplyWindowInsetsListener(root) { view, windowInsets ->
val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
// Apply the insets as a margin to the view. Here the system is setting
// only the bottom, left, and right dimensions, but apply whichever insets are
// appropriate to your layout. You can also update the view padding
// if that's more appropriate.
view.layoutParams = (view.layoutParams as FrameLayout.LayoutParams).apply {
leftMargin = insets.left
bottomMargin = insets.bottom
rightMargin = insets.right
}
// Return CONSUMED if you don't want want the window insets to keep being
// passed down to descendant views.
WindowInsetsCompat.CONSUMED
}
}
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);
}
}
