如何在TextView或其他Android上显示HTML代码？ [英] How to show html codes inside TextView or something else on Android?

问题描述

如何在TextView或其他东西中显示html源代码？
我试过这个：

  @Override 
 public void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.main）; 
 TextView tv =（TextView）findViewById（R.id.tv1）; 
 String s =< img src = \http://images2.layoutsparks.com/1/146278/purple-lotus-lovely-dew.jpg\/>; 
 Spanned sp = new SpannableString（s）; 
 
 tv.setText（Html.toHtml（sp））; 
} 
  

但是我得到了：

解决方案

TextView中的HTML支持相当有限，但以下是您可以执行的一些操作的示例：

 < string name =fun_text>我喜欢& lt; font color = \'0x00b0f1\\''> BLUE！& lt; / font>和& lt; b>粗体&安培; LT / B个和< i>斜体&安培; LT / I>和< u>下划线&安培; LT; / U>< /串GT; 
  

然后重设文字，如下所示：

  String styledText = tv.getText（）。toString（）; 
 tv.setText（Html.fromHtml（styledText），TextView.BufferType.SPANNABLE）; 
  

开源的美妙之处在于您可以在Android源代码中看到Html.fromHtml（）支持的内容：

如果您正在寻找更高级的内容，请查看 WebView

How can I show html source as rendered in TextView or something else? I tried this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView tv = (TextView) findViewById(R.id.tv1);
    String s = "<img src=\"http://images2.layoutsparks.com/1/146278/purple-lotus-lovely-dew.jpg\"/>";
    Spanned sp = new SpannableString(s);

    tv.setText(Html.toHtml(sp));
}

But I got:

解决方案

HTML support in a TextView is pretty limited, but here is an example of some of the things you can do:

https://github.com/brianjolly/TextFun

The key is escaping the opening bracket in your strings.xml

<string name="fun_text">I like &lt;font color=\'0x00b0f1\'>BLUE!&lt;/font> and &lt;b> Bold&lt;/b> and &lt;i> italic&lt;/i> and &lt;u> underline&lt;/u></string>

And then resetting the text like so:

String styledText = tv.getText().toString();
tv.setText(Html.fromHtml(styledText), TextView.BufferType.SPANNABLE);

The beauty of open source is you can see what Html.fromHtml() supports in the android source here:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/text/Html.java

If you're looking to do something more advanced take a look at WebView
