The screen displays the results should be and initial AndroidPhoneDialer phase matching. The description of the function around a number of different concepts. First, you must program a button, the button's properties within the file main.xml. Next, you must create a function to start a coding project CALL_ACTION this Intent to Finally, your button should be able to perform this function and start Intent to. The equal sign on the left part of the code in the Create button. The right is the call button from the file main.xml property. To call its properties, you use findViewByID (delivery) the results of a button. This sounds more complicated than it actually. The measurement of the codes of  Cell Phone Jammers  is stated above are defined.
Now you have a button, but you need it to do something. The button itself unable to complete the code too much work. The purpose of this case, you need to let it come to execution CALL_ACTION this Intent to Therefore, you need to create a small function in your existing Intent call. Thus, when the button is pressed, you can call. If you are familiar with Java programming, there is nothing strange. The code on the left is the receiver of the program, only the binding button to onClick. The receiver is very familiar to Java programmers. For people who are not familiar with Java or receiver. The receiver is the Java object from other objects "acceptable". The specification is applicable to Cell Phone Jammers .
The same concept also applies to Android. In Android, the receiver, to allow the Android Views handle the call from the other input. For this project you need for your button to create a receiver to accept the activities of the button's onclick event. If you are familiar with Java development, this structure should not seem strange. This is the implementation of the Java in typical onClickListener interface. You will see here is to use a Java anonymous class for the button to execute the onClickListener. Also, as an anonymous class, you can be used as a local variable - in this case the button, if the variable is defined as the ultimate. The manufacturer can revise this specification of  Cell Phone Jammers .
In the simulator to compile and run this event. The main activities will be labeled Show Dialer button. Click this button, it should open the Call activities and dial 555-1212. The main activities should be as follows (abbreviated). As you can see, Android is a very robust and flexible platform. A few lines of code, less than one, you have created an activity and use of equipment, telephone hardware by the button to start. Similarly, on this point, you should be on the Android-processing activities, Intent and Views of the way first came to comfort. Your AndroidPhoneDialer activities are still not very sound. You need to add one more entry.
