使状态栏悬停在 activity 时遇到问题

Getting troubles making status bar hovering the activity

我有一个网站,我决定为它做一个 Android 应用程序,但我实际上是在 win32 下用 c++ 编写的,并且从未在 Android 下编程过。所以我决定只制作一个 Blink 渲染实例,使其适合我应用程序的屏幕尺寸并自动加载我的网站。另外我想让状态栏悬停在"activity",网上搜了下也没办法,请指点,我哪里错了。东西应该从 Android 4.4 及更高版本开始工作。在 Android 工作室工作

我现在有什么:

我想要什么:

我的代码:

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapplication">
<uses-permission android:name="android.permission.INTERNET" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:fitsSystemWindows="true">


<WebView
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    />

styles.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">#000000</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

MainActivity.java

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

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

    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE|View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

    WebView myWebView = findViewById(R.id.webview);
    myWebView.setWebViewClient(new WebViewClient());
    myWebView.loadUrl("http://somesite.com");
    WebSettings webSettings = myWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);


}
}

在您的网络视图顶部添加进度条

<ProgressBar android:id="@+id/pB1"
    style="?android:attr/progressBarStyleHorizontal" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:layout_centerVertical="true"
    android:padding="2dip">
</ProgressBar>

然后你需要像这样在进度条上设置进度状态:

myWebView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {
               if(progress < 100 && pbar.getVisibility() == ProgressBar.GONE){
                   pbar.setVisibility(ProgressBar.VISIBLE);
                   }

               pbar.setProgress(progress);
               if(progress == 100) {
                   pbar.setVisibility(ProgressBar.GONE);
                  }
            }
        });

在 onCreate 上试试这个,这将使两者都透明

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

或尝试

getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
