同一个textview中设置字体不同样式
例子1:
设置部分文字背景高亮显示:
同时设置文字和背景高亮显示:
参数说明:
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
API里面解释:Spans of type SPAN_EXCLUSIVE_EXCLUSIVE do not expand to include
text inserted at either their starting or ending point. They can never
have a length of 0 and are automatically removed from the buffer if all
the text they cover is removed.
即在原文本头或尾追加新文本的样式不受原文本样式影响,原文本高亮,新追加文本不高亮。
Spannable.SPAN_EXCLUSIVE_INCLUSIVE
API里面解释:Non-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand to
include text inserted at their ending point but not at their starting
point. When 0-length, they behave like points.
即在原文本尾追加新文本的样式受原文本样式影响,原来文本尾高亮,新追加文本也高亮
例子2:
功能:实现在一个TextView里显示了一行字符串,需要这个串里字符显示不同颜色.
代码如下:
第二种方式:
String newMessageInfo = "<font color='red'><b>" + 红色内容
+ "</b></font>TextView学习显示不同颜色";
mTextView.setTextView(Html.fromHtml(newMessageInfo));
例子3:
SpannableString ss = new SpannableString( "红色打电话粗体删除线绿色下划线图片:.");
ss.setSpan(new ForegroundColorSpan(Color.RED), 0, 2,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new URLSpan("tel:4155551212"), 2, 5,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new StyleSpan(Typeface.BOLD), 5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new StrikethroughSpan(), 7, 10,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new UnderlineSpan(), 10, 16,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new ForegroundColorSpan(Color.GREEN), 10, 15, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Drawable d = getResources().getDrawable(R.drawable.icon48x48_1);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
ss.setSpan(span, 18, 19, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
TextView t4 = (TextView) findViewById(R.id.text4);
t4.setText(ss);
t4.setMovementMethod(LinkMovementMethod.getInstance());
例子4:
效果图:
Activity代码:
String sSendTimeValue="bbb"
Spannable WordtoSpan = new SpannableString(conValue+"\n"+sSendTimeValue);
WordtoSpan.setSpan(new AbsoluteSizeSpan(30), 0, conValue.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
WordtoSpan.setSpan(new AbsoluteSizeSpan(20), conValue.length(), conValue.length()+sSendTimeValue.length()+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
WordtoSpan.setSpan(new ForegroundColorSpan(Color.GRAY), conValue.length(), conValue.length()+sSendTimeValue.length()+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
