Android移动端操作系统
Android是一种基于Linux的自由及开放源代码的操作系统,主要使用于移动设备,如智能手机和平板电脑,由Google公司和开放手机联盟领导及开发。尚未有统一中文名称,中国大陆地区较多人使用“安卓”或“安致”。
本文实例讲述了Android编程实现的短信编辑器功能。分享给大家供大家参考,具体如下:
修改短信数据库,从而生成任意手机号发送的短信。

SimpleDateFormat formatter = new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
Date curDate = new Date(System.currentTimeMillis());//获取当前时间

textSMS = textSMS + currentTime;
getMessage.setText(textSMS);
}
});
//发送短信
sendMessage.setOnClickListener(new View.OnClickListener() {
@Override

if (TextUtils.isEmpty(getPhone.getText().toString())) {
Toast.makeText(MainActivity.this, "电话号码未填写", Toast.LENGTH_SHORT).show();
return;
}

return;
}
//获取电话号码和短信内容
phoneNum = Integer.parseInt(getPhone.getText().toString());
textSMS = getMessage.getText().toString();
//开启多线程
Thread thread = new Thread() {

ContentResolver resolver = getContentResolver();
ContentValues values = new ContentValues();
values.put("address", phoneNum);
