【达内课程】Android中短信相关操作

发送短信

发短信关键代码

SmsManager smsManager = SmsManager.getDefault();
        String number = et_phone_number.getText().toString();
        String text = et_sms_content.getText().toString();
        smsManager.sendTextMessage(number,null,text,null,null);

AndroidManifest.xml中增加权限

<uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

测试一下
这种用代码发送的短信，是不会进入到短消息数据库的
没有对数据库进行任何操作

现在我们做一个功能，当短信发送成功，或失败，Toast下

主要代码如下，xml代码请自行脑补

public class SmsActivity extends Activity implements View.OnClickListener {
    private static final String ACTION_SEND_SMS_OK_OR_NOT = "ACTION_SEND_SMS_OK_OR_NOT";
    private static final String ACTION_RECEIVE_SMS_OK_OR_NOT = "ACTION_RECEIVE_SMS_OK_OR_NOT";
    private Button btn_send;
    private EditText et_phone_number;
    private EditText et_sms_content;
    private SmsStateReceiver receiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sms);

        initViews();
        setListeners();
        //注册广播接收器
        receiver = new SmsStateReceiver();
        IntentFilter filter = new IntentFilter(ACTION_SEND_SMS_OK_OR_NOT);
        this.registerReceiver(receiver,filter);
    }

    @Override
    protected void onDestroy() {
        this.unregisterReceiver(receiver);
        super.onDestroy();
    }

    private void setListeners() {
        btn_send.setOnClickListener(this);
    }

    private void initViews() {
        btn_send = findViewById(R.id.btn_send);
        et_phone_number = findViewById(R.id.et_phone_number);
        et_sms_content = findViewById(R.id.et_sms_content);
    }


    @Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.btn_send:
                sendSms();
                break;
        }
    }

    private void sendSms() {
        SmsManager smsManager = SmsManager.getDefault();
        String number = et_phone_number.getText().toString();
        String text = et_sms_content.getText().toString();
        //提示用户短信是否发送成功
        Intent i1 = new Intent(ACTION_SEND_SMS_OK_OR_NOT);
        PendingIntent p1 = PendingIntent.getBroadcast(this,0,i1,PendingIntent.FLAG_UPDATE_CURRENT);
        //提示对方是否成功接收短信
        Intent i2 = new Intent(ACTION_RECEIVE_SMS_OK_OR_NOT);
        PendingIntent p2 = PendingIntent.getBroadcast(this,0,i2,PendingIntent.FLAG_UPDATE_CURRENT);
        smsManager.sendTextMessage(number,null,text,p1,p2);
    }

    /**
     * 短信收发状态的广播接收器
     */
    class SmsStateReceiver extends BroadcastReceiver{

        @Override
        public void onReceive(Context context, Intent intent) {
            int code = getResultCode();//结果码
            String action = intent.getAction();
            if(ACTION_SEND_SMS_OK_OR_NOT.equals(action)){
                switch (code){
                    case Activity.RESULT_OK://成功发送
                        Toast.makeText(SmsActivity.this,"发送成功",Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Toast.makeText(SmsActivity.this,"发送失败",Toast.LENGTH_SHORT).show();
                        break;
                }
            }else if(ACTION_RECEIVE_SMS_OK_OR_NOT.equals(action)){
                //提示是否接收成功
                switch (code){
                    case Activity.RESULT_OK://成功发送
                        Toast.makeText(SmsActivity.this,"对方已成功接收",Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Toast.makeText(SmsActivity.this,"对方接收失败",Toast.LENGTH_SHORT).show();
                        break;
                }
            }
        }
    }
}

长短信

使用sendTextMessage发送短信会有70字限制，超过70个字，就会发送不成功

关键代码如下，在之前的基础上修改：

......
        //提示对方是否成功接收短信
        Intent i2 = new Intent(ACTION_RECEIVE_SMS_OK_OR_NOT);
        PendingIntent p2 = PendingIntent.getBroadcast(this,0,i2,PendingIntent.FLAG_UPDATE_CURRENT);
        //处理大文本短信
        ArrayList<String> bodies = smsManager.divideMessage(text);
        for(String body:bodies){
            smsManager.sendTextMessage(number,null,body,p1,p2);
        }

拦截短信

数据库读取短信

/data/data/com.android.providers.Telephoney/databases/
