首先描述下需求：
1宵凌、新增短信時(shí)，進(jìn)來(lái)收件人是為空止后，顯示一行文字（提醒）
2瞎惫、從通訊錄選擇聯(lián)系人后，回到短信編輯界面译株，收件欄顯示一行瓜喇，內(nèi)容為“收件人：XXX、XXX歉糜、XXX欠橘、XXX.....”
3、當(dāng)點(diǎn)擊收件欄時(shí)现恼，收件欄內(nèi)容變化肃续，變成可刪除,最多顯示四行，多余四行有上下滑動(dòng)輪叉袍，不足四行始锚，是幾行顯示幾行
4、填寫短信內(nèi)容喳逛，即時(shí)計(jì)算短信條算瞧捌，并有文本提示
下面是實(shí)現(xiàn)后效果圖
下面終于到了代碼實(shí)現(xiàn)塊了，主要寫一些主要用到的類润文，其他不太重要的就忽略寫姐呐，讀者自行補(bǔ)全。
首先是短信收件人是一個(gè)自定義的流布局典蝌，這個(gè)流布局不是本人寫的曙砂，只是在上面加了些修改來(lái)滿足自己的業(yè)務(wù)需求。

txt_add_message_add_content_word
.setText("("
+?getSMSCounts(edittext_edit_message_add_content
.getText().toString()
.trim().length())?+")");
}
}
});
接收刪除后的handler處理：
[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)?+"");
}
};
};
上面已經(jīng)把關(guān)鍵的代碼都貼出來(lái)了柱告，其實(shí)最重要的 地方是按流布局去顯示收件人，原生的是沒有限制顯示行數(shù)笑陈，也沒有處理多行后的滑動(dòng)輪际度，頭疼的地方是去計(jì)算顯示高度并動(dòng)態(tài)設(shè)置scrollview的高地『祝坑都已經(jīng)踩過(guò)了乖菱，但是這個(gè)代碼的效率不是很高，有待繼續(xù)完善蓬网，或者有什么好的建議也可以給我提窒所。
