短信可以直接在第三方应用程序（android）上打开吗？

当一条短信以表单形式发送时，比如说一个应用程序“myApp”，它将在接收方的默认短信应用程序中打开。但我想控制它对接收器的外观（比如改变颜色）。在本机应用程序“myApp”中是否有发送文本和读取文本的方法？或者识别它是从“myApp”发送的，并将消息导入“myApp”。

确保您可以接收消息，使广播接收器在每次消息到达时接收消息，启动显示消息的活动

public class SMSApp extends IntentReceiver {
    private static final String LOG_TAG = "SMSApp";

    /* package */ static final String ACTION =
            "android.provider.Telephony.SMS_RECEIVED";

    public void onReceiveIntent(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION)) {
            StringBuilder buf = new StringBuilder();
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                SmsMessage[] messages = Telephony.Sms.Intents.getMessagesFromIntent(intent);
                for (int i = 0; i < messages.length; i++) {
                    SmsMessage message = messages[i];
                    buf.append("Received SMS from  ");
                    buf.append(message.getDisplayOriginatingAddress());
                    buf.append(" - ");
                    buf.append(message.getDisplayMessageBody());
                }
            }
           //start you messages activity 

        Intent i = new Intent();
        i.setClassName("com.test", "com.test.myMessagesAcivity");
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        //prepare message text to be sent to the activity via bundle 
        Bundle bundle = new Bundle();
        bundle.putString("message", but.toString());
        i.putExtras(bundle);
        context.startActivity(i);


        }
    }


}

并在清单文件中添加这些权限

<uses-permission android:id="android.permission.RECEIVE_SMS" />

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

<receiver class="SMSApp">

            <intent-filter>

                <action android:value="android.provider.Telephony.SMS_RECEIVED" />

            </intent-filter>

        </receiver>

public void eb3atSMS(String phoneNumber, String message)
    {        

        PendingIntent pi = PendingIntent.getActivity(this, 0,
            new Intent(this, **DummyClasshere.class**), 0);                
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, message, pi, null);        
    }
