Question

这是我的标签导航栏，这也与我的其他子页面重叠

<ion-header>
  <ion-navbar hideBackButton="true">
    <span class="hdr-clr">Winkrr</span>
    <ion-buttons start>
      <button ion-button icon-only>
        <ion-icon style="color:#ed145b;" name="ios-search"></ion-icon>
      </button>
    </ion-buttons>
    <ion-buttons end>
      <button ion-button icon-only>
        <ion-icon style="color:#ed145b;" name="ios-notifications-outline"></ion-icon>
      </button>
    </ion-buttons>
    <ion-buttons end>
      <button ion-button icon-only>
        <ion-icon style="color:#ed145b;" name="ios-contact-outline"></ion-icon>
      </button>
    </ion-buttons>
  </ion-navbar>
</ion-header>
<ion-tabs tabsPlacement="top" tabsHideOnSubPages="true" primary>
  <ion-tab tabIcon="md-globe" [root]="tab1Root"></ion-tab>
  <ion-tab tabIcon="stats" [root]="tab2Root"></ion-tab>
</ion-tabs>

这是我的子页面导航栏

<ion-header>

  <ion-navbar hide-tabs>
    <ion-title>personal-chat</ion-title>
  </ion-navbar>

</ion-header>

这就是我导航的方式

  onContact(){
    this.navCtrl.push(PersonalChatPage);
  }

我在离子2中使用了单页标签。我已经将离子导航栏用于标签页，这对于两个标签很常见。但是相同的导航栏出现在子页面
上

您可以尝试在app.module.ts中设置配置，如下所示：

ArrayList<Integer> points = new ArrayList<>();

public Line(String filePath) {
    points = readFile(filePath);
}

public void paintComponent(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;

    if(points!= null && points.size()>=4) {
        g2d.drawLine(points.get(0), points.get(1), points.get(2), points.get(3));
    }
}

public ArrayList<Integer> readFile(String filePath){
    BufferedReader br = null;
    FileReader fr = null;
    ArrayList<Integer> list = new ArrayList();

    try {

        //br = new BufferedReader(new FileReader(FILENAME));
        fr = new FileReader(filePath);
        br = new BufferedReader(fr);

        String sCurrentLine;

        while ((sCurrentLine = br.readLine()) != null) {
            String[] splitted = sCurrentLine.split(",");
            for (int i = 0; i < splitted.length; i++) {
                try {
                    list.add(Integer.parseInt(splitted[i].trim()));
                }
                catch (Exception ex){
                    System.out.println(splitted[i] + " is not a valid number/integer");
                }
            }
        }

        System.out.println(list);

    }
    catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            if (br != null)
                br.close();
            if (fr != null)
                fr.close();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

    return list;
}

IONIC Tabs navbar出现在子页面中为什么？
