Android 显示 html 文本的最佳方式

Question

我有带有html tags, 的字符串links，image links那么显示该字符串的最佳方式是什么？我知道人们Webview为此而使用，但也许有一种方法可以在 textview 中做到这一点而无需投入太多工作？因为会WebView出现不同的问题，例如，如果您想更改文本颜色，则需要为该字符串添加额外的样式。我对使链接可点击并在同一文本视图中显示图像的方法感兴趣。

Try using this:-

Html.fromHtml("your html code");

Example:-

txtvw.setText(Html.fromHtml("<p align=right> <b> "
        + "Hi!" + " <br/> <font size=6>"
        + " How are you "+"</font> <br/>"
        + "I am fine" + "  </b> </p>"));

Output:-

嗨
你好吗
我很好

**Full Code With Image And Hyperlink**:-

import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.text.Html;
import android.text.method.LinkMovementMethod;
import android.widget.TextView;

public class MainActivity extends Activity {

 String htmlString = "<img src='ic_launcher'><i>Welcome to<i> <b><a href='https://stackoverflow.com/'>Stack Overflow</a></b>";

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  TextView htmlTextView = new TextView(this);
  setContentView(htmlTextView);

  htmlTextView.setText(Html.fromHtml(htmlString, new Html.ImageGetter(){

   @Override
   public Drawable getDrawable(String source) {
    Drawable drawable;
    int dourceId = 
      getApplicationContext()
      .getResources()
      .getIdentifier(source, "drawable", getPackageName());

    drawable = 
      getApplicationContext()
      .getResources()
      .getDrawable(dourceId);

    drawable.setBounds(
      0, 
      0, 
      drawable.getIntrinsicWidth(),
      drawable.getIntrinsicHeight());

    return drawable;
   }

  }, null));

  htmlTextView.setMovementMethod(LinkMovementMethod.getInstance());

 }

}

To support all API use this function:-

@SuppressWarnings("deprecation")
public static Spanned fromHtml(String html) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY);
    }
    else {
        return Html.fromHtml(html);
    }
}
