調用Activity 中的finish()方法即可：

button1.setOnClickListener(new OnClickListener() {          
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(FristActivity.this, "You clicked Button1", 
                        Toast.LENGTH_SHORT).show();
                finish();
                Log.d("FristActivity", "Activity finish");
            }
        });
