Question

I know how to make it so you will open a new page onClick but when I put the same code into onTouch it doesnt work? This is the code I have… any help for me if I click on the error I get a message saying “The constructor Intent(Tab3, Class) is undefined” and it wants me to set it to “= new Intent” but that doesnt make sence to me.

public boolean onTouch(View v, MotionEvent event) 
    {
        if(rect2.contains((int) event.getX(),(int) event.getY()))
        {
            Intent SectionManager = new Intent (this, SectionManager.class);
            startActivity (SectionManager);
        }
        return true;
    }

EDIT
more information on my code!

public class Tab3 extends View implements OnTouchListener
{
    LinearLayout myLayout;
    int x1, x2, y1, y2, x, y;
    // x, y;
    Rect rect2 = new Rect();

    public Tab3(Context context, AttributeSet attrs)
    {
        super (context, attrs);

        myLayout = (LinearLayout) findViewById(R.id.myLayout);

        x1 = 0;
        x2 = 300;               //1280 by 748
        y1 = 0;
        y2 = 300;




        setFocusable(true);
        setFocusableInTouchMode(true); 
        setOnTouchListener(this);
        requestFocus();
    }

    @Override
    protected void onDraw(Canvas canvas) 
    {
        super.onDraw(canvas);

        Paint blue = new Paint();
        blue.setColor(Color.BLUE);
        canvas.drawRect(rect2, blue);
        rect2.set(x1, y1, x2, y2);

        invalidate();
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) 
    {
        if(rect2.contains((int) event.getX(),(int) event.getY()))
        {
            Intent SectionManager = new Intent (Tab3.this, SectionManager.class);
            startActivity (SectionManager);
        }
        return true;
    }
}

Answer 1

your context is wrong you need to use YourClassName.this inside there not just this. currently this means the view aka Tab3 which is not the context

public class MyActivity extends Activity{
            .
            all your activity stuff here
            .
            .
public class Tab3 extends View implements OnTouchListener{

LinearLayout myLayout;
int x1, x2, y1, y2, x, y;
// x, y;
Rect rect2 = new Rect();

public Tab3(Context context, AttributeSet attrs)
{
    super (context, attrs);

    myLayout = (LinearLayout) findViewById(R.id.myLayout);

    x1 = 0;
    x2 = 300;               //1280 by 748
    y1 = 0;
    y2 = 300;




    setFocusable(true);
    setFocusableInTouchMode(true); 
    setOnTouchListener(this);
    requestFocus();
}

@Override
protected void onDraw(Canvas canvas) 
{
    super.onDraw(canvas);

    Paint blue = new Paint();
    blue.setColor(Color.BLUE);
    canvas.drawRect(rect2, blue);
    rect2.set(x1, y1, x2, y2);

    invalidate();
}

@Override
public boolean onTouch(View v, MotionEvent event) 
{
    if(rect2.contains((int) event.getX(),(int) event.getY()))
    {
        Intent SectionManager = new Intent (MyActivity.this, SectionManager.class);
        startActivity (SectionManager);
    }
    return true;
}
} //end Tab3 Class
} //end MyActivity

Tab3 is a sub class of MyActivity now and you should be able to do MyActivity.this
