Answer 1

You need to call another activity like this inside the OnClickListener() of button

Button mondayEdit= (Button)findViewById(R.id.button1);
    mondayEdit.setOnClickListener(new OnClickListener() 
    {   public void onClick(View v) 
        {   
            Intent intent = new Intent(main.this, secondActivity.class);
                startActivity(intent);      
                finish();
        }
    });

Probably your code is showing error due to Android manifest file, Try adding proper class in manifest file. Making first activity as main , and other as default.Others part of code is exactly fine.
