Using Intent For Sending Sms On Button Click From Widget

Ok this is code for my widget. I have two buttons, that are making calls when clicking on them. I want to implement three more buttons for sending SMS, but i can't implement intent

Solution 1:

Have you used the smsmanager as follows:

SmsManagersm= SmsManager.getDefault();
sm.sendTextMessage(destinationAddress, null, "Hello world", null, null, null);

In addition to your code I would suggest you to override onReceive() method in the WidgetProvider in order to handle sending SMS. The basic implementation could look like this:

First in onUpdate():

Intentintent=newIntent(context, WidgetProvider.class);
intent.setAction(ACTION_SEND_SMS);
PendingIntentpendingIntent= PendingIntent.getBroadcast(context, 0, intent, 0);

And then:

@OverridepublicvoidonReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
    if (intent.getAction().equals(ACTION_SEND_SMS)) {
        SmsManagersm= SmsManager.getDefault();
        sm.sendTextMessage(destinationAddress, null, "Hello world", null, null, null);
    }
} 

And in the Manifest:

<receiverandroid:name="com.packagename.WidgetProvider" ><intent-filter><actionandroid:name="android.appwidget.action.APPWIDGET_UPDATE" /><actionandroid:name="com.packagename.ACTION_SEND_SMS"/></intent-filter><meta-dataandroid:name="android.appwidget.provider"android:resource="@xml/widget_info" /></receiver>

Hope that helps

First define list of messages. There are many ways - in this example you can store them in the string array:

String[] messages = newString[]{"Message for button 1", "Message for button 2", "Message for button 3"};
Stringnumber = "12344444454"// recipient's mobile number

Initialize SmsManager:

SmsManagersm= SmsManager.getDefault();

Now add onClick listener to your buttons:

Button button1 = (Button)findViewById(R.id.yourbutton1);
Button button2 = (Button)findViewById(R.id.yourbutton2);
Button button3 = (Button)findViewById(R.id.yourbutton3);

button1.setOnClickListener(newOnClickListener(){
    @OverridepublicvoidonClick(View v) {
        //Sending message 1
        sm.sendTextMessage(number, null, messages[0], null, null, null);
    }
});

button2.setOnClickListener(newOnClickListener(){
    @OverridepublicvoidonClick(View v) {
        //Sending message 2
        sm.sendTextMessage(number, null, messages[1], null, null, null);
    }
});

button3.setOnClickListener(newOnClickListener(){
    @OverridepublicvoidonClick(View v) {
        //Sending message 3
        sm.sendTextMessage(number, null, messages[2], null, null, null);
    }
});
