类似MIUI原生短信编辑功能

小学生写代码

类似MIUI原生短信编辑功能

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。

实例化一个收件人adapter

[java]view plain copy

@SuppressLint("NewApi")

@Override

SpannableStringBuilder sp1 =newSpannableStringBuilder(

s);// 姓名

SpannableStringBuilder sp2 =newSpannableStringBuilder(

sp1.setSpan(

newForegroundColorSpan(Color

.rgb(102,102,102)),0, s.length(),

if(position !=0) {

meBean.getReceiver().remove(position);

handler.sendEmptyMessage(1);

}

}

});

returntv;

}

};

计算短信条数方法：

[java]view plain copy

/**

* 计算短信内容条算

*

* @param wordNum

* @return

*/

publicintgetSMSCounts(intwordNum) {

intcounts;

if(wordNum <=63)

counts =1;

elseif(wordNum <=127)

counts =2;

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 plain copy

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) {

if(getSMSCounts(edittext_edit_message_add_content

.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 plain copy

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。
