FragmentActivity的简单使用

如图是效果图

当  点击下面 不同 的按钮 进入 不同的界面

其中 要一个 主布局当做容器 ， 和3个不同的 布局来对应下面的3个按钮界面

主程序的 代码和布局如下

 import android.support.v4.app.Fragment;
 import android.support.v4.app.FragmentTransaction;
 import android.view.View;
 import android.widget.Button;
 
 import com.example.huanshop.activity.R;
 import com.example.huanshop.activity.main.MyShopFragment;
 import com.example.huanshop.base.BaseFragmentActivity;
 
 public class ProducteTimeLimit extends BaseFragmentActivity {
     private int index;
     // 当前fragment的index
     private int currentTabIndex;
     private TimeLimitShopFragment timeLimitShop;
     private TimeLimitQiangShop timeLimitQiangShop;
     private MyShopFragment myShopFragment;
     private Fragment[] fragments;
     private Button[] btnTabs;
 
     @Override
     protected void setContentView() {
         // TODO Auto-generated method stub
         setContentView(R.layout.timeshop);
     }
 
     @Override
     protected void setFindViewById() {
         // TODO Auto-generated method stub
         btnTabs = new Button[3];
         btnTabs[0] = (Button) findViewById(R.id.timelimited);
         btnTabs[1] = (Button) findViewById(R.id.lastshop);
         btnTabs[2] = (Button) findViewById(R.id.brandshop);
         // 把第一个设置成默认选中状态
         btnTabs[0].setSelected(true);
 
     }
 
     @Override
     protected void setControll() {
         // TODO Auto-generated method stub
         timeLimitShop = new TimeLimitShopFragment();
         timeLimitQiangShop = new TimeLimitQiangShop();
         myShopFragment = new MyShopFragment();
         fragments = new Fragment[] { timeLimitShop, timeLimitQiangShop,
                 myShopFragment };
         // 添加显示第一个fragment
         getSupportFragmentManager().beginTransaction()
                 .add(R.id.timeshopfragment, timeLimitShop)
                 .add(R.id.timeshopfragment, timeLimitQiangShop)
                 .add(R.id.timeshopfragment, myShopFragment)
                 .hide(timeLimitQiangShop).hide(myShopFragment)
                 .hide(myShopFragment).show(timeLimitShop).commit();
     }
 
     @Override
     protected void setListener() {
         // TODO Auto-generated method stub
 
     }
 
     public void onTabClicked(View view) {
         switch (view.getId()) {
         case R.id.timelimited:
             index = 0;
             break;
         case R.id.lastshop:
             index = 1;
             break;
         case R.id.brandshop:
             index = 2;
             break;
         }
         if (currentTabIndex != 0) {
             btnTabs[0].setSelected(false);
         }
         if (currentTabIndex != index) {
             FragmentTransaction trx = getSupportFragmentManager()
                     .beginTransaction();
             trx.hide(fragments[currentTabIndex]);
 
             if (!fragments[index].isAdded()) {
                 trx.add(R.id.timeshopfragment, fragments[index]);
             }
             trx.show(fragments[index]).commit();
         }
         btnTabs[currentTabIndex].setSelected(false);
         // 把当前tab设为选中状态
         btnTabs[index].setSelected(true);
         currentTabIndex = index;
     }
 
 }
