按钮到错了位置

Question

所以我的申请遇到了一些问题，bt3带我到bt2位置，当我不想要它时，有人可以解释一下原因吗？

 public class MainActivity extends Activity {
    Button bt, bt2, bt3;
                @Override
                protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.activity_main);

                    bt = (Button) findViewById(R.id.button1);
                    bt2 = (Button) findViewById(R.id.button2);
                    bt3 = (Button) findViewById(R.id.button3);



                    bt.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {
                            IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
                            integrator.initiateScan();
                        }
                    });

                    bt2.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View arg0) {

                            Intent intent = new Intent(MainActivity.this, location1.class);
                            startActivity(intent);

   }

                    });



                    bt3.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View arg0) {

                            Intent intent = new Intent(MainActivity.this, location2.class);
                            startActivity(intent);





                        }
                    });

                }

        public void onActivityResult(int requestCode, int resultCode, Intent intent) 
                    {
                        //super.onActivityResult(requestCode, resultCode, intent);
                        if (requestCode == 0) {
                            if (resultCode == RESULT_OK) {

                            } else if (resultCode == RESULT_CANCELED) {

                            }
                        }
                    }


                @Override
                public boolean onCreateOptionsMenu(Menu menu) {
                    // Inflate the menu; this adds items to the action bar if it is present.
                    getMenuInflater().inflate(R.menu.main, menu);
                    return true;
                }

            }

澄清每个按钮的作用：

button1用来开始扫描，

button2用来带我去location1，

button3用来带我到location2。

您可以尝试为XML中的每个按钮实现onClick方法，看看是否会发生任何变化。
