    Default how do I rewrite this program to android program? and what am I doing wrong ?

    Hello everyone.

    I have this code in java, and I tired to convert it to android, but it dose won't to work:

     
    public ShopPhone() {
    		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		setBounds(100, 100, 450, 300);
    		contentPane = new JPanel();
    		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    		contentPane.setLayout(new BorderLayout(0, 0));
    		setContentPane(contentPane);
     
    		tF = new JTextField();
    		contentPane.add(tF, BorderLayout.NORTH);
    		tF.setColumns(10);
    		tF.setText("");
     
     
    		JButton btnNewButton = new JButton("New button");
    		btnNewButton.addActionListener(new ActionListener() {
    			public void actionPerformed(ActionEvent e) {
     
     
    				if(tF.getText().equals("x")){
     
    					x = "5733689997";
     
    				}
    				 JOptionPane.showMessageDialog(null, x);
    			}
    		});
    		contentPane.add(btnNewButton, BorderLayout.SOUTH);
    	}
     
    }


    and this my code for the android:

     
    public class MainActivity extends ActionBarActivity {
     
    	public EditText search;
    	public TextView print;
    	public Button bFind;
     
    	protected String name;
     
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
     
    		if (savedInstanceState == null) {
    			getSupportFragmentManager().beginTransaction()
    					.add(R.id.container, new PlaceholderFragment()).commit();
    		}
     
     
    		search = (EditText) findViewById(R.id.find);
    		print = (TextView) findViewById(R.id.show);
    		bFind = (Button) findViewById(R.id.press);
    		bFind.setOnClickListener(new OnClickListener() {
     
    			@Override
    			public void onClick(View v) {
     
    				if(search.getText().equals("name")){
     
    					name = "horyah";
    				}			
    				print.setText(name);
    			}
     
    		});
     
    	}

    what am I doing wrong
    Please explain.
    If you get error messages, copy the full text and paste it here.
    If the program executes differently than you want, explain what it does and what you want it to do.
    If you don't understand my answer, don't ignore it, ask a question.

    I don't get an error, but one I press on the button ( Find ) it won't show the name or do anything

    Is the listener called? Add a call to println() to the listener to see if it is called. Print out the value of name for example. The output will show in the LogCat window.

    I'm sorry I did not understand what do you mean. what I'm trying to do is a searching box. For example; in basic java it work fine.

    Look at this code:




    if(tF.getText().equals("x1")){

    x1 = "5733689997";

    }

    if(tF.getText().equals("x2")){

    x2 = "123456789";

    }

    if( x1 == null){

    x1 = "";
    }

    if( x2 == null){

    x2 = "";
    }

    JOptionPane.showMessageDialog(null, x1 + x2);

    x1 = "";
    x2 = "";

    Please wrap the code in code tags not in quote tags.

    The code has lost all of its formatting and indentations.

    Why are you posting this simple bit of code?

    will this not the real code for the android programming as I said before. It's just an example in basic java, and this code is working, but what I really want is making a search box in android Similar or may be different in code to what I wrote in basic java

    There are several ways to present a "dialog window" where a question can be asked and a response received.
    I've often found lots of code examples by doing a search on the internet.

    There aren't too many experienced Android programmers on this forum. I've written a few apps but not enough .
