android开发 单击按钮 实现页面间的跳转

我的MainActivity.java部分代码

 public class MainActivity extends ActionBarActivity {
     //不要定义button类型，会出错
     View imageButton1, imageButton2,imageButton3,imageButton4,
     imageButton5,imageButton6;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         if (savedInstanceState == null) {
             getSupportFragmentManager().beginTransaction()
             .add(R.id.container, new PlaceholderFragment()).commit();
         }
         //根据ID找到界面中的组件按钮
         imageButton1=findViewById(R.id.imageButton1);
         imageButton2=findViewById(R.id.imageButton2);
         imageButton3=findViewById(R.id.imageButton3);
         imageButton4=findViewById(R.id.imageButton4);
         imageButton5=findViewById(R.id.imageButton5);
         imageButton6=findViewById(R.id.imageButton6);
         //创建监听器对象
         ButtonListener bt = new ButtonListener();
         //注册监听
         imageButton1.setOnClickListener(bt);
         imageButton2.setOnClickListener(bt);
         imageButton3.setOnClickListener(bt);
         imageButton4.setOnClickListener(bt);
         imageButton5.setOnClickListener(bt);
         imageButton6.setOnClickListener(bt);
     }

     class ButtonListener implements OnClickListener
     {
         //实现单击事件处理方法
         @Override
         public void onClick(View v) {
             // TODO Auto-generated method stub
             if(v == imageButton1)
             {
                 //导航
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
             if(v == imageButton2)
             {
                 //搜索
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
             if(v == imageButton3)
             {
                 //地图
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
             if(v == imageButton4)
             {
                 //周边
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
             if(v == imageButton5)
             {
                 //推荐
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
             if(v == findViewById(R.id.imageButton6))
             {
                 //其他
                 Intent intent = new Intent();
                 intent.setClass(MainActivity.this, OtherActivity.class);
                 startActivity(intent);
             }
