一个类似MIUI中原生短信编辑功能

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

adapter = new TagAdapter<String>(meBean.getReceiver()) {
					final LayoutInflater mInflater = LayoutInflater
							.from(AddMessageActivity.this);

					@SuppressLint("NewApi")
					@Override
					public View getView(FlowLayout parent, final int position,
							final String s) {
						final TextView tv = (TextView) mInflater.inflate(
								R.layout.item_label_tv_medium,
								tfl_add_message_labellay, false);
						SpannableStringBuilder sp1 = new SpannableStringBuilder(
								s);// 姓名
						SpannableStringBuilder sp2 = new SpannableStringBuilder(
								"x");// 删除
						sp1.setSpan(
								new ForegroundColorSpan(Color
										.rgb(102, 102, 102)), 0, s.length(),
								Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
						sp2.setSpan(
								new ForegroundColorSpan(Color.rgb(255, 0, 0)),
								0, "X".length(),
								Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

						SpannableStringBuilder sp = new SpannableStringBuilder();//
						sp.append(sp1).append(sp2);

						if (position == 0) {
							tv.setText(s);
							tv.setTextColor(android.graphics.Color
									.parseColor("#666666"));
						} else {
							tv.setText(sp);
							tv.setTextSize(16);
							tv.setBackgroundResource(R.drawable.selector_contacts_gray_btn);
						}
						tv.setOnClickListener(new View.OnClickListener() {

							@Override
							public void onClick(View v) {
								// 跳页面带值
								if (position != 0) {
									meBean.getReceiver().remove(position);
									handler.sendEmptyMessage(1);
								}
							}
						});
						return tv;
					}
				};

计算短信条数方法：

/**
	 * 计算短信内容条算
	 *
	 * @param wordNum
	 * @return
	 */
	public int getSMSCounts(int wordNum) {
		int counts;
		if (wordNum <= 63)
			counts = 1;
		else if (wordNum <= 127)
			counts = 2;
		else {
			counts = (wordNum - 127) % 67 == 0 ? ((wordNum - 127) / 67 + 2)
					: ((wordNum + 7) / 67 + 1);
		}
		return counts;
	}

监听编辑文本框来提示短信条数和字数：

edittext_edit_message_add_content
				.addTextChangedListener(new TextWatcher() {

					@Override
					public void onTextChanged(CharSequence s, int start,
							int before, int count) {
						// TODO Auto-generated method stub

					}

					@Override
					public void beforeTextChanged(CharSequence s, int start,
							int count, int after) {

					}

					@Override
					public void afterTextChanged(Editable s) {
						if (getSMSCounts(edittext_edit_message_add_content
								.getText().toString().trim().length()) == 1) {
							int c = 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("");
						} else if (getSMSCounts(edittext_edit_message_add_content
								.getText().toString().trim().length()) == 2) {
							int c = 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)");
						} else if (getSMSCounts(edittext_edit_message_add_content
								.getText().toString().trim().length()) > 2) {
							int c = 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：

private Handler handler = new Handler() {
		public void handleMessage(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。
