setOnClickListener error - cannot resolve symbol
<p>I want to create a button which, when clicked, it will show another intent.</p>

<p>This is the code:</p>

<pre><code>   &lt;Button
    android:text="Bine ati venit!"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/button1"
    android:background="#479fc7"
    android:textSize="40dp"
    android:textColor="@color/colorPrimaryDark"
    android:textStyle="normal|bold|italic"
    android:textAllCaps="false"
    android:fontFamily="casual"
    android:onClick="next_page"/&gt;
</code></pre>

<p>and from the .java class:</p>

<pre><code>    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcome);
}

Button button = (Button) findViewById(R.id.button1);

button.setOnClickListener( new View.OnClickListener()
{
    public void onClick (View v){
    next_page(v);
}
});

public void next_page(View v) {
    Intent intent = new Intent(this, MapsActivity.class);
    startActivity(intent);
}
</code></pre>

<p>I get the errors:
"Cannot resolve symbol 'setOnClickListener'", "variable onClick is never used", "; expected"....</p>
