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;
    }

}
