Question

如何在文字左侧添加垂直线？
我正在动态地在TextView中显示一个blockquote html。

。

Answer 1

放在textView的左侧，并使用所需的尺寸和颜色。

     <View
        android:layout_width="2dp"
        android:layout_height="100dp"
        android:background="@color/colorPrimaryDark"></View>

Answer 2

使用

    WebView webview = (WebView)this.findViewById(R.id.webview);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.loadDataWithBaseURL("", data, "text/html", "UTF-8", "");

将webview用于Html文本

      String a = "You can ";
      String b = "change" ; 
      String c = "like this" ; 
      String d = "if want to make it bold"; 
      String sourceString = a + " " + "<b>" + b + "</b>" + " " + c + " " + "<b>" + d + "</b>"; 
      textView.setText(Html.fromHtml(sourceString));

这是您想要的代码

  public Form1()
    {
        InitializeComponent();

        List<KeyValuePair<string, bool>> UrlS = Link_Bul_v2("http://www.asdfhg.com", new List<string>(), new List<KeyValuePair<string, bool>>());
        List<KeyValuePair<string, bool>> UrlS2 = Link_Bul_v2("http://www.huuene.com", new List<string>(), new List<KeyValuePair<string, bool>>());

    }



    string UrlSadelesti(string Link)
    {
        return Link.Replace("https://", "").Replace("http://", "").Replace("www.", "");
    }

    WebClient client = new WebClient();
    private List<KeyValuePair<string, bool>> Link_Bul_v2(string Link, List<string> HList, List<KeyValuePair<string, bool>> CList)
    {


        try
        {

            string HtmlCode = client.DownloadString(Link);

            //if(HtmlCode.

            CList.Add(new KeyValuePair<string, bool>(Link, true));
            var Link_Short = UrlSadelesti(Link).Split('/')[0];
            //HList.Add(Link_Short);

            string DLink;
            int IndexH = 0;
            while (true)
            {
                IndexH = HtmlCode.IndexOf("href", IndexH);
                if (IndexH == -1) { break; }

                if (HtmlCode[IndexH - 1] == '.')
                {
                    IndexH = IndexH + 1;

                }
                else
                {

                    var IndexD1 = HtmlCode.IndexOf('"', IndexH);

                    var IndexD2 = HtmlCode.IndexOf('"', IndexD1 + 1);

                    var length = IndexD2 - (IndexD1 + 1);

                    DLink = HtmlCode.Substring(IndexD1 + 1, length);

                    IndexH = IndexD2;


                    if ((DLink.Contains(".css") == false))
                    {
                        if (DLink.Contains("http://") || DLink.Contains("https://"))
                        {
                            if (DLink.Contains(Link_Short) == false)
                                continue;

                        }
                        if (DLink.Contains("#"))
                        {
                            continue;
                        }
                        DLink = UrlSadelesti(DLink).Replace(Link_Short, "");

                        if (DLink.Length == 1)
                            continue;

                        if (HList.Count(p => p.Contains(DLink)) == 0)
                        {
                            if (DLink.Contains("http://") || DLink.Contains("https://"))
                            {
                                HList.Add(Link_Short + "/" + DLink);
                            }
                            else
                            {
                                HList.Add("http://" + Link_Short + "/" + DLink);
                            }
                        }
                    }
                }
            }
        }
        catch
        {
            CList.Add(new KeyValuePair<string, bool>(Link, false));
            if (!HList.Contains(Link))
                HList.Add(Link);

            if (UrlSadelesti(Link).Split('/').Count() > 1)
            {
                Link_Bul_v2("http://" + UrlSadelesti(Link).Split('/')[0], HList, CList);
            }
        }
        foreach (string s in HList)
        {
            if (CList.Count(p => p.Key.Contains(s)) == 0)
            {
                Link_Bul_v2(s, HList, CList);
            }
        }
        return CList;

    }

它看起来像

你可以更改这样如果想要加粗

Answer 3

您可以使用View：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:padding="10dp"
  android:orientation="horizontal">

  <View   
    android:layout_gravity="right"
    android:background="#000000"
    android:layout_width="2dp"
    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp"
    android:layout_height="match_parent" />

  <TextView
   android:text="balblalblablalblablalblalb"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content" />

</LinearLayout>

看起来像：

要显示Html，您可以执行以下操作：

yourTextView.setText(Html.fromHtml("your html string"));

Answer 4

Step 1: Add a Linear layout in a layout.
<LinearLayout
    android:id="@+id/linear_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_margin="10dp">

</LinearLayout> 
step2:In Activity , create TextView and a View dynamically  add to linear layout
 LinearLayout mylayout = (LinearLayout) findViewById(R.id.linear_layout);

    TextView text = new TextView(this);
    text.setText("Testing");

    View view = new View(this);
    view.setBackgroundColor(getResources().getColor(R.color.black));
    view.setLayoutParams(new LinearLayout.LayoutParams(5, LinearLayout.LayoutParams.MATCH_PARENT));

    mylayout.addView(view,0);
    mylayout.addView(text,1);

希望它有所帮助！
