首先描述下需求：
1、新增短信时，进来收件人是为空，显示一行文字（提醒）
2、从通讯录选择联系人后，回到短信编辑界面，收件栏显示一行，内容为“收件人：XXX、XXX、XXX、XXX.....”
3、当点击收件栏时，收件栏内容变化，变成可删除,最多显示四行，多余四行有上下滑动轮，不足四行，是几行显示几行
4、填写短信内容，即时计算短信条算，并有文本提示
下面是实现后效果图
下面终于到了代码实现块了，主要写一些主要用到的类，其他不太重要的就忽略写，读者自行补全。
首先是短信收件人是一个自定义的流布局，这个流布局不是本人写的，只是在上面加了些修改来满足自己的业务需求。

计算短信条数方法：
[java]view plaincopy
/**

publicintgetSMSCounts(intwordNum) {
intcounts;
if(wordNum <=63)

else{
counts = (wordNum -127) %67==0? ((wordNum -127) /67+2)
: ((wordNum +7) /67+1);
}
returncounts;
}
监听编辑文本框来提示短信条数和字数：
[java]view plaincopy
edittext_edit_message_add_content
.addTextChangedListener(newTextWatcher() {
@Override
publicvoidonTextChanged(CharSequence s,intstart,
intbefore,intcount) {
// TODO Auto-generated method stub
}
@Override
publicvoidbeforeTextChanged(CharSequence s,intstart,
intcount,intafter) {
}
@Override
publicvoidafterTextChanged(Editable s) {

.getText().toString().trim().length()) ==1) {
intc =63- edittext_edit_message_add_content
.getText().toString().trim().length();
txt_add_message_add_content_num.setText(c +"");
txt_add_message_add_content_word.setText("");
}elseif(getSMSCounts(edittext_edit_message_add_content
.getText().toString().trim().length()) ==2) {
intc =127- edittext_edit_message_add_content
.getText().toString().trim().length();
txt_add_message_add_content_num.setText(c +"");
txt_add_message_add_content_word.setText("(2)");
}elseif(getSMSCounts(edittext_edit_message_add_content
.getText().toString().trim().length()) >2) {
intc = getSMSCounts(edittext_edit_message_add_content
.getText().toString().trim().length())
*67
-7
- edittext_edit_message_add_content
.getText().toString().trim()
.length();
txt_add_message_add_content_num.setText(c +"");
txt_add_message_add_content_word
.setText("("
+ getSMSCounts(edittext_edit_message_add_content
.getText().toString()
.trim().length()) +")");
}
}
});
接收删除后的handler处理：
[java]view plaincopy
privateHandler handler =newHandler() {
publicvoidhandleMessage(android.os.Message msg) {
if(msg.what ==1) {
tfl_add_message_labellay.onChanged();
txt_add_message_customer_counts.setText((meBean.getReceiver()
.size() -1) +"");
}
};
};
上面已经把关键的代码都贴出来了，其实最重要的 地方是按流布局去显示收件人，原生的是没有限制显示行数，也没有处理多行后的滑动轮，头疼的地方是去计算显示高度并动态设置scrollview的高地。坑都已经踩过了，但是这个代码的效率不是很高，有待继续完善，或者有什么好的建议也可以给我提。
