基于Android4.0短信发送案例(SMS)

老规矩，先看图，再看代码。

 

 

看图吧，layout我就不写了。下面看主要代码

 

public class MainActivity extends Activity implements OnClickListener{
    private EditText phone;
    private EditText msg;
    private Button send;
    //输入的电话号码符合以下格式标准
    //private static final Pattern GLOBAL_PHONE_NUMBER_PATTERN = Pattern.compile("[\\+]?[0-9.-]+");
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        send = (Button) findViewById(R.id.button1);
        phone = (EditText) findViewById(R.id.phone);
        phone.setText(R.string.defaultPhone);
        phone.addTextChangedListener(new TextWatcher() {
            //当一个对象的类型是连接到一个可编辑的，它的方法被调用时，更改文本。
            @Override
            public void onTextChanged(CharSequence s, int start, int before,int count) {
                System.out.println("onTextChanged = " + s.toString());
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,int after) {
                System.out.println("beforeTextChanged = " + s.toString());
            }

            @Override
            public void afterTextChanged(Editable s) {
                if (isNotPhone(s.toString())) {
                    phone.setTextColor(ColorStateList.valueOf(Color.RED));
                } else {
                    phone.setTextColor(Color.BLACK);
                }
            }

        });
        msg = (EditText) findViewById(R.id.msg);
        msg.setText(R.string.defaultMsg);
        send.setOnClickListener(this);
    }

    public void sendSms(View view) {
        //管理短信操作，如发送数据，文本和PDU短信。由调用静态方法SmsManager.getDefault的（）获取该对象。
        SmsManager smsManager = SmsManager.getDefault();
        String phoneNumber = phone.getText().toString();
        if (isNotPhone(phoneNumber)) {
            phone.setTextColor(ColorStateList.valueOf(Color.RED));
            showLongMsg(R.string.wrongNumber);
            return;
        }
        String msgStr = msg.getText().toString();
        if (isEmpty(msgStr)) {
            showLongMsg(R.string.msgEmpty);
            return;
        }
        //源码翻译说明
        //分割成几个碎块，没有大于的最大SMS消息大小的消息文本
        //个人理解意思:把发送消息的内容分割几个小块内容，然后进行字符串特别处理返回ArrayList<String>,进行遍历
        //（至于怎么特别处理,要看源码，我也只是大概的看了一下，不是很明白原理 0.0）
        for (String str : smsManager.divideMessage(msgStr)) {
//          try {
//              ISms iccISms = ISms.Stub.asInterface(ServiceManager.getService("isms"));
//              if (iccISms != null) {
//                  iccISms.sendText(destinationAddress, scAddress, text, sentIntent, deliveryIntent);
//              }
//          } catch (RemoteException ex) {
//              // ignore it
//          }
            //通过以上代码进行短信发送的.看源码找不到ISms这个类(太神奇了,表示压梨山大)
            smsManager.sendTextMessage(phoneNumber, null, str, null, null);
        }
        showLongMsg(R.string.successInfo);
    }

    private boolean isEmpty(String msgStr) {
        return msgStr == null || msgStr.trim().length() == 0;
    }

    private void showLongMsg(int stringId) {
        Toast.makeText(this, stringId, Toast.LENGTH_LONG).show();
    }

    private boolean isNotPhone(String phoneNumber) {
        return !PhoneNumberUtils.isGlobalPhoneNumber(phoneNumber);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }


    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case Menu.FIRST:
            finish();
            break;

        default:
            break;
        }
        return true;
    }

    @Override
    public void onClick(View v) {
        sendSms(v);
    }
