This project is developed in Eclipse 4.2.0.
1.
Make some ImageButton by XML Layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageButton android:id="@+id/button_1"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:background="@drawable/image_button_up"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:onClick="button_click"/>
<ImageButton android:layout_below="@id/button_1"
android:layout_alignLeft="@id/button_1"
android:id="@+id/button_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:background="@drawable/image_button_left"
android:layout_marginLeft="-57dp"
android:layout_marginBottom="10dp"
android:onClick="button_click"/>
<ImageButton android:layout_below="@id/button_1"
android:layout_alignLeft="@id/button_1"
android:id="@+id/button_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:background="@drawable/image_button_right"
android:layout_marginLeft="57dp"
android:layout_marginBottom="10dp"
android:onClick="button_click"/>
<ImageButton android:layout_below="@id/button_3"
android:layout_alignLeft="@id/button_3"
android:id="@+id/button_4"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:background="@drawable/image_button_down"
android:layout_marginLeft="-57dp"
android:layout_marginBottom="30dp"
android:onClick="button_click"/>
</RelativeLayout>
For android:background attribute of each ImageButton we need
a xml file in folder drawable, for example:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="@drawable/down_button_press" />
<item
android:state_enabled="true"
android:drawable="@drawable/down_button" />
</selector>
2. Code: Add click listener for the ImageButton
When
user click on the ImageButton the SMS with phone number and message content
will be send automatically
public void button_click(View view){
String phone_string ="";
String
sms_string ="";
switch(view.getId()) {
case R.id.button_1:
phone_string
= "01234678345";
sms_string = "SMS
content 1";
break;
case R.id.button_2:
phone_string
= "01694846123";
sms_string = "SMS
content 2";
break;
case R.id.button_3:
phone_string
= "0912123789";
sms_string = "SMS
content 3";
break;
case R.id.button_4:
phone_string
= "0988163066";
sms_string = "SMS
content 4";
break;
}
// send
message
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phone_string,
null, sms_string, null, null);
// show alert
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Your message will be sent");
alertDialog.setMessage("Phone Number: " + phone_string
+ "\nSMS Message: " + sms_string);
alertDialog.setButton("Close", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// here you
can add functions
}
});
alertDialog.show();
}
