Method not called when launched

Question

so I'm kinda new to android developing.

I read this as my reference to have a clickable button, with some changes in my xml. The problem that I have is, whenever I tried to click it, nothing happens. There's no error message on my phone nor android studio. I wonder what's missing or is there something that I don't know, that I should know?

Here's my java on my project

public class test_button extends Activity {
Button button ;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test_button);
    click();
}
public void click(){
    button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

                        Intent browserIntent =
                                new Intent(Intent.ACTION_VIEW, Uri.parse("http://reddit.com"));
                        startActivity(browserIntent);
        }
    });
}

and this is my xml

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">

<include layout="@layout/layout_toolbar"
    android:layout_height="?attr/actionBarSize"
    android:layout_width="match_parent"
    android:id="@+id/toolbar"/>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:id="@+id/profile_page_activity_body"
    android:layout_below="@id/toolbar"
    >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="60sp"
        android:text="Do things"
        android:textColor="#ffffff"
        android:textSize="40sp"
        android:id="@+id/button"
        android:textAllCaps="false"
        android:background="@drawable/btn_greenbox"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="51dp" />


</RelativeLayout>

Edit1 : on onClick(), i did try Toast, but it had similar outcome, nothing happened.

Edit2 : there's a click animation on button whenever i click it

Answer 1

call intent like this may in your link have a problem:

into click:-

**Intent i = new Intent(Intent.ACTION_VIEW, 
           Uri.parse("https://www.reddit.com/"));
    startActivity(i);**

Just Put a https://www.reddit.com/ instead of http://www.reddit.com/

Answer 2

How about setting click listener as:

public class TestButton extends Activity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.button);
        btn.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {

        // Intent code here;
    }
}

Answer 3

Set the onclick listenter inside the onCreate instead of that method and try.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test_button);
    button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

                        Intent browserIntent =
                                new Intent(Intent.ACTION_VIEW, Uri.parse("http://reddit.com"));
                        startActivity(browserIntent);
        }
    });
}

Also, test_button is not a good name for a class. Change it to TestButton . (Rename using refactoring [shift+f6], so that you do not get reference errors)
