文章标题 Android系统广播的发送短信和接收短信的一些用法

//<1>实现的一些功能

按钮：（设置安全号码）—–>对话框（手动添加/从通讯录有中获取）

立马：发短信（SMSManager）给安全号码发送短信

要在AndroidManifest.xml这里里面加上权限 如下：

<!--发送短信的权限-->
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>``
<!-- 读取联系人 -->
<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
<!--读取短信的权限-->
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

主要功能有1.通过 Intent跳转到自带的手机联系人，在通过获取联系人的获得联系人的ID号， 获得联系人电话的cursor，通过ID可以获取号码，2.发送通过 SmsManager smsManager = SmsManager.getDefault();短信来的

private EditText num;
private EditText content;
private Button btnSends;
private SharedPreferences.Editor ed;
private String strNo;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//得到号码的编辑器
num = (EditText) findViewById(R.id.Number);
//得到内容的编辑器
content = (EditText) findViewById(R.id.Content);
//得到联系人
btnSends = (Button) findViewById(R.id.btnSends);

//可以SharedPreference储存数据

SharedPreferences sp= getSharedPreferences("loginfo", Context.MODE_PRIVATE);
//使号码进行第二次打开时可以保存
ed = sp.edit();
String name=sp.getString("name","");
num.setText(name);
//
btnSends.setOnClickListener(new Button.OnClickListener() {

@Override
public void onClick(View v) {
//跳转手机自带的联系人
// TODO Auto-generated method stub
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

MainActivity.this.startActivityForResult(intent, 1);
}

});
}

@Override

Cursor cursor = managedQuery(contactData, null, null, null,
null);
cursor.moveToFirst();
//得到你选择的手机号码
String nums = this.getContactPhone(cursor);
Log.i("test", "所选手机号为：" + nums);
//将编辑器直接赋值
num.setText( nums);
}
break;

private String getContactPhone(Cursor cursor) {
// TODO Auto-generated method stub

String result = "";
if (phoneNum > 0) {
// 获得联系人的ID号
int idColumn = cursor.getColumnIndex(ContactsContract.Contacts._ID);
String contactId = cursor.getString(idColumn);
// 获得联系人电话的cursor
Cursor phone = getContentResolver().query(

//保存手机号码

//如果字数超过5,需拆分成多条短信发送
if (strContent.length() > 5) {

}
} else {

9ddb

}

//content.setText("1.*#*#7780#*#*");

//Toast.makeText(SendSMS.this, "短信发送完成", Toast.LENGTH_LONG).show();
