android 实现发送短信功能

 在学习的视频里面发现了这个发送短信的功能实现 就好奇写了一个小demo

先看一下页面的效果吧

很简单的布局 两个输入框 一个按钮 看一下具体的实现效果 emmmm 模拟器上看不出来效果 骚等....

 点击发送短信 提示了发送成功 看一下能否接收到短信呢? 那就一起来看一下吧

成功的发送过来了 也是非常的nice 个人感觉没啥用的东西0.0

一起来看看代码吧(总感觉这玩意没用......)

public class SendSMSSActivity extends AppCompatActivity {
    private EditText edContent;
    private EditText edPhone;
 
    private static final int SEND_SMS = 100;
 
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_send_smss);
 
        edContent = findViewById(R.id.ed_content);
        edPhone = findViewById(R.id.ed_phone);
        Button btSend = findViewById(R.id.bt_sendSMSS);
        btSend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                requestPermission();
            }
        });
    }
 
 
 
 
    private void requestPermission() {
        //判断Android版本是否大于23
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int checkCallPhonePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE);
            if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, SEND_SMS);
                return;
            } else {
                sendSMSS();
                //已有权限
            }
        } else {
            //API 版本在23以下
        }
    }
 
    /**
     * 注册权限申请回调
     *
     * @param requestCode  申请码
     * @param permissions  申请的权限
     * @param grantResults 结果
     */
    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case SEND_SMS:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    sendSMSS();
                } else {
                    // Permission Denied
                    Toast.makeText(SendSMSSActivity.this, "CALL_PHONE Denied", Toast.LENGTH_SHORT).show();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
 
    //发送短信
    private void sendSMSS() {
        String content = edContent.getText().toString().trim();
        String phone = edPhone.getText().toString().trim();
        if (!StringUtil.isEmpty(content) && !StringUtil.isEmpty(phone)) {
            SmsManager manager = SmsManager.getDefault();
            ArrayList<String> strings = manager.divideMessage(content);
            for (int i = 0; i < strings.size(); i++) {
                manager.sendTextMessage(phone, null, content, null, null);
            }
            Toast.makeText(SendSMSSActivity.this, "发送成功", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "手机号或内容不能为空", Toast.LENGTH_SHORT).show();
            return;
        }
 
    }
}

SmsManager 短信管理器

manager.sendTextMessage(destinationAddress, scAddress, text, sentIntent, deliveryIntent);

destinationAddress: 收件人号码

scAddress: 短信中心服务号码, 这里设置为null

text: 发送内容

sentIntent: 发送短信结果状态信号(是否成功发送),new 一个Intent , 操作系统接收到信号后将广播这个Intent.此过程为异步.

deliveryIntent: 对方接收状态信号(是否已成功接收).

 短信属于危险权限组记得动态权限0.0
