public class HtmlTextView extends TextView {

public static final String TAG = "HtmlTextView";
public static final boolean DEBUG = false;

public HtmlTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    } else {
        imgGetter = new UrlImageGetter(this, getContext());
    }
    // this uses Android's Html class for basic parsing, and HtmlTagHandler
    setText(Html.fromHtml(html, imgGetter, new Html.TagHandler() {
        @Override
        public void handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader) {

        }
    }));
    // make links work
    setMovementMethod(LinkMovementMethod.getInstance());
    setTextColor(getResources().getColor(R.color.shell_news_content));
    }
}

【使用】
（1）在布局中:

      <com.shuixin.mvpshell.widget.HtmlTextView
                android:id="@+id/htv"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:textColor="@color/shell_font_black"
                android:textSize="18sp"/>

(2) 在代码中：

 mHtv.setHtmlFromString(“ ”,false);
