ionic2 改变状态栏颜色

有一个点要特别注意，就是！安卓版本要5.0以上 。

参考文章：https://segmentfault.com/a/1190000009078477

其中头两项是修改MainActivity.java文件，以下是修改后的MainActivity.java文件的所有内容

MainActivity.java的路径为：platformsandroidsrccomionicframework

package com.ionicframework.smartwms328018;

import android.os.Bundle;
import org.apache.cordova.*;
import android.os.Build;
import android.view.View;

public class MainActivity extends CordovaActivity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// Set by <content src="index.html" /> in config.xml

//安卓状态栏透明
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN |
View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
}

loadUrl(launchUrl);
}
}

第二步:在项目根目录的config.xml文件中添加下面配置，这里需要注意
颜色的设置至关重要，此处是八位hex color，前两位是透明度，后六位是rgb颜色值．so根据自己的需要配置．
<preference name="StatusBarBackgroundColor" value="#551b1d23" />

第三步: 在app.scss中添加样式

 

.platform-android {
    ion-header {
      padding-top: $cordova-md-statusbar-padding;
      background-color: color($colors, primary);
    }
}

第四步: 在appComponent.ts 文件中添加下面这段代码

platform.ready().then(() => {

   if (this.platform.is('android')) {

       this.statusBar.backgroundColorByHexString("#55fb7981");

   }

})
