TextView富文本显示

1.使用类似Html的标签显示图像

        tv = (TextView) findViewById(R.id.text);        ImageGetter imageGetter = new ImageGetter() {            @Override            public Drawable getDrawable(String source) {                // TODO Auto-generated method stub                Drawable drawable = getResources().getDrawable(                        R.drawable.ic_launcher);                drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),                        drawable.getIntrinsicHeight());                return drawable;            }        };        Spanned spanned = Html.fromHtml(                "这是一个<font color='#00ffff'>富文本</font>,然后加一个图标<img src=''/>",                imageGetter, null);        tv.setText(spanned);        tv.getPaint().setAntiAlias(true);// 抗锯齿

2.使用ImageSpan在TextView上显示图像

      TextView textView = (TextView) findViewById(R.id.textsss);        //根据资源id获取资源的bitmap对象        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);        //根据bitmap创建ImageSpan对象        ImageSpan imageSpan = new ImageSpan(getApplicationContext(), bitmap);        //方便插入ImageSpan对象        SpannableString spannableString = new SpannableString("icon");        //ImageSpan对象替换icon的从0开始的2位        spannableString.setSpan(imageSpan, 0, 2, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);        textView.setText(spannableString);

3.TextView点击链接操作

    SpannableString spannableString = new SpannableString("icon");        //ImageSpan对象替换icon的从0开始的2位        spannableString.setSpan(new ClickableSpan() {            @Override            public void onClick(View view) {            }        },0,2,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);        textView.setText(spannableString);        //在单击链接凡是有操作的，都需要设置MovementMethod        textView.setMovementMethod(LinkMovementMethod.getInstance());    }
