java - 在android中发送短信时显示 Activity

Question

我正在开发 Android 应用程序。在我的应用程序中，我需要向收件人发送短信。如果向收件人发送短信，它将显示 toast 消息并显示新 Activity 。我使用了 SMSManager 类，但我不想在中使用 SMSManager我的应用程序。我想使用发送短信的 Intent ，这为我提供了用于发送消息的默认短信 View 。我使用 Intent 成功发送短信但无法调用其他 Activity 。请解决我的这个问题我做了很多研发但没有成功。

我附上了发送短信和调用 Activity 的源代码

try {
    String smsSent = "SMS_SENT";
    String smsDelivered = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(smsSent), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
    new Intent(smsDelivered), 0);

    // Receiver for Sent SMS.
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS sent", Toast.LENGTH_SHORT).show();
                    Intent i=new Intent(this,Display.class).startActivity(i);
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(smsSent));

    // Receiver for Delivered SMS.
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered", Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered", Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(smsDelivered));


    /*SmsManager smsman=SmsManager.getDefault();
    smsman.sendTextMessage(no, null, data, null, null);*/

    /*  
    // called new activity here
    Intent i=new Intent(MainActivity.this,Display.class);
    startActivity(i);
    Toast.makeText(getApplicationContext(), "SMS sent",Toast.LENGTH_LONG).show();
    */


    Intent smsIntent = new Intent(Intent.ACTION_VIEW);
    smsIntent.setType("vnd.android-dir/mms-sms");
    smsIntent.putExtra("address", "");
    smsIntent.putExtra("sms_body","");
    startActivity(smsIntent);  
} catch(Exception e) {
    Toast.makeText(getApplicationContext(), "SMS faild, please try again.", Toast.LENGTH_LONG).show();      
    e.printStackTrace();
}

Answer 1

您可以使用onActivityResult方法。

编辑您的代码如下:

Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address", "");
smsIntent.putExtra("sms_body","");
startActivityForResult(smsIntent, MY_REQUEST_CODE);//MY_REQUEST_CODE int number

然后您可以重写 onActivityResult() 并在那里捕获该请求代码(在启动 Activity 中自行定义)。它看起来像这样:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (requestCode == MY_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
        // do something useful
        }
    }
}
