Question

I\'ve added a button to my activity XML file and I can\'t get it to open my other activity. Can some please tell me step by step on how to do this?

Answer 1

Write code on xml file.

Write Code in your java file

Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            startActivity(new Intent(getApplicationContext(),Secondclass.class));
           /* if you want to finish the first activity then just call
            finish(); */
        }
    });
