*/

private Button b1,b2,b3,b4;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

this.btn = (Button) findViewById(R.id.button1);

b1=(Button) findViewById(R.id.b1);

b2=(Button) findViewById(R.id.b2);

b3=(Button) findViewById(R.id.b3);

b4=(Button) findViewById(R.id.b4);

int kai = R.drawable.isa_xiayiye;

int guan = R.drawable.isa_xiayiye_2;

if (shifou == kai) {

shifou = guan;

} else if (shifou == guan) {

shifou = kai;

switch (v.getId()) {

case R.id.b1:
