It is the result of the quality of  Cell Phone Jammers in the workshop.
Do not put the name of the image-sensitive mixed up. The name of the picture should be lowercase. If you insert a capital letter, when you try Eclipse using this file, you will get an error prompt. Copy this file to the correct directory. helloworld.png this image should be displayed in the Project window, drawable directory. Open R.java and look at its code. Eclipse should be increased by a pointer to helloworld.png your R.java file should be similar with the following. This is the introduction to quality assurance of  Cell Phone Jammers .
With a clean shell as a starting point, and a usable handle to the image you want to display, you can start to increase your code. This application can either point of view: the XML-based UI and code-based UI. Assume that you can understand that part of HelloWorldText, this version of the HelloWorld! Would be more familiar with. To get started, you need to enter the display picture functions of packaging. The text of a TextView picture display will use ImageView. Therefore, you must enter the the ImageView packaging. And TextView ImageView included in android.widgets years. This is the process inspection of  Cell Phone Jammers . 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 quality control procedure of  Cell Phone Jammers  is important.
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 role and responsibility should be distributed.
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.
