thanks Kate. the place you put it is more appropriate.

Need to see your code, and you need to explain what you mean by "not working".

 

[Steven Spiegel]

thanks so much for willing to help me. the code will follow. this xml file with the modifications I did will not open.
my intent is to have full vertical scroll.

[wseng92]

You have closed Linear Layout tag

android:layout_height="230dp" />

The correct should be

android:layout_height="230dp" >

in the mainactivity.java file below getting errors when attempting to build app
please help me fix errors.

public class MainActivity extends AppCompatActivity {
    private Button mButton;
    [USER=1021285]@override[/USER]
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button activityButton = (Button) findViewById(R.id.button_quiz);
        activity@Button.setOnClick(value = new OnClickListener(),
                toolbar = (Toolbar) findViewById(R.id.toolbar), setSupportActionBar = (toolbar), mButton = (Button) findViewById(R.id.button_quiz), mButton =, setOnClickListener = (new OnClickListener() {
            [USER=1021285]@override[/USER]
            public void onClick(View view) {
                //open url using Intent
                String url = "http://www.cancunsteve.com/capecod/mobilepopquiz2.htm";
                Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));


            }
        }

 

[wseng92]

What errors you getting?

 

[Steven Spiegel]

what errors am I not getting!
OnClickListener is abstract cannot be instantiated
cannot resolve activity (this refers to activity@Button)
in find ViewById(R.id.toolbar) it says attribute value must be constant
")" expected (where I have two } )
; expected (same place)

is there any hope??????????

 

[Deleted User]

Your code has so many problems, I don't know where to start. Well let's begin with this

activity@Button

If you can't see why that's a problem, stop coding now, and pick up the first book you find on Java, and start reading. If you're doing cut/paste coding, then try to understand the code you're using. Otherwise you'll have endless problems, and you'll never achieve anything.

So tell me, what do you think that statement at line 9 is trying to do?

 

[kate]

Lines 4 and 11 got messed up by the forum auto-linking to a user name with USER.

@Steven Spiegel when you post code use code tags:

[code]
Your
code
here
[/code]

 

[Steven Spiegel]

the click listener is to know if the button is activated (clicked) this button loads the url in question
not sure why it calls a new click listener though
will follow your advice for posting code
bought an expensive book on android coding but it explains more to open new activity
if all else fails will go that route

However expensive the book you bought, I'll bet it doesn't explain the basics of the Java programming language.
You need to do the foundation work before you can build the house.

 

[Steven Spiegel]

thanks for your help

 

[wseng92]

[USER=1021285]@override[/USER]

@Override not @override

 

[Steven Spiegel]

thanks will try

 

[Steven Spiegel]

have two errors stemming from the manifest when trying to compile.
my mainactivity.java is fine I believe.
the errors are cannot find activity class NewActivity2. cannot find symbol variable activity_main
manifest below:

<?xml version="1.0" encoding="utf-8"?>

Did your MainActivity java class extend to AppCompatActivity ?

 

[Steven Spiegel]

believe so here is an excerpt (hope I did it correctly)

public class MainActivity extends AppCompatActivity {
    Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get the view from activity_main.xml
        setContentView(R.layout.activity_main);

        // Locate the button in activity_main.xml
        button = (Button) findViewById(R.id.MyButton);

        // Capture button clicks
        button.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {

                // Start NewActivity.class
                Intent myIntent = new Intent(MainActivity.this,
                        NewActivity2.class);
                startActivity(myIntent);
            }
        });
    }

 

[wseng92]

MainActivity java class looked good.

Look at this errors again

the errors are cannot find activity class NewActivity2. cannot find symbol variable activity_main

Do you have NewActivity2 java class ?
If yes, did the class extends to AppCompatActivity ?

 

[Deleted User]

android:name=".NewActivity2"

Use the full package name of this class.

 

[Steven Spiegel]

in my mainactivity.java I do not have NewActivity2 java class. nor am I sure the correct way to enter it correctly
now I have

public class MainActivity extends AppCompatActivity {
    Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get the view from activity_main.xml
        setContentView(R.layout.activity_main);

        // Locate the button in activity_main.xml
        button = (Button) findViewById(R.id.MyButton);

        // Capture button clicks
        button.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {

                // Start NewActivity.class
                Intent myIntent = new Intent(MainActivity.this,
                        NewActivity2.class);
                startActivity(myIntent);
            }
        });
    }

should I put public class NewActivity2 extends AppCompatActivity {
Button button;
then all the same code after @override as above? not sure?

 

[wseng92]

When button in MainActivity is clicked, it should open NewActivity2 (that's what I can see from your code).
So you have to create NewActivity2 class and do whatever you want in that class.

 

[Steven Spiegel]

I just want the NewActivity2.class to open and display the content of activity_main2.xml but not sure the correct coding for that
