Android简单的Fragment嵌套Fragment(Viewpager+Fragement)

我的项目目录如下：

直接上核心代码
MainActivity
import android.support.v4.app.FragmentTransaction;
import android.graphics.Color;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.view.View;
import android.view.Window;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.example.fragmentlayout.Fragment.MainFragment;
import com.example.fragmentlayout.Fragment.MineFragment;
import com.example.fragmentlayout.Fragment.MoreFragment;

public class MainActivity extends FragmentActivity implements View.OnClickListener {
private TextView main_textview,more_textview,mine_textview;
private ImageView main_imageview,more_imageview,mine_imageview;
private RelativeLayout main_layout,more_layout,mine_layout;
private Fragment mainFragment,moreFragment,mineFragment;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);//删除自带标题栏(如果继承AppCompatActivity,不起效果,所以继承FragmentActivity)
    setContentView(R.layout.activity_main);
    initView();
    setSelect(0);//显示第一个Fragment (0代表mainFragment,1代表moreFragment,2代表mineFragment);
}

private void initView() {
    main_imageview=(ImageView)findViewById(R.id.main_iamgeview);
    more_imageview=(ImageView)findViewById(R.id.more_iamgeview);
    mine_imageview=(ImageView)findViewById(R.id.mine_iamgeview);

    main_textview=(TextView)findViewById(R.id.main_textview);
    more_textview=(TextView)findViewById(R.id.more_textview);
    mine_textview=(TextView)findViewById(R.id.mine_textview);

    main_layout=(RelativeLayout)findViewById(R.id.main_layout);
    more_layout=(RelativeLayout)findViewById(R.id.more_layout);
    mine_layout=(RelativeLayout)findViewById(R.id.mine_layout);

    main_layout.setOnClickListener(this);
    more_layout.setOnClickListener(this);
    mine_layout.setOnClickListener(this);

}

private void setSelect(int i) {
    FragmentManager fm=getSupportFragmentManager();
    FragmentTransaction transaction=fm.beginTransaction();
    hideFragment(transaction);
    switch (i){
        case 0:
            if(mainFragment==null){
                mainFragment=new MainFragment();
                transaction.add(R.id.fragment,mainFragment);
            }else {
                transaction.show(mainFragment);
            }
            break;
        case 1:
            if(moreFragment==null){
                moreFragment=new MoreFragment();
                transaction.add(R.id.fragment,moreFragment);
            }else {
                transaction.show(moreFragment);
            }
            break;
        case 2:
            if(mineFragment==null){
                mineFragment=new MineFragment();

            }
            break;
    }
    transaction.commit();//提交事务
}

private void hideFragment(FragmentTransaction transaction) {
    if(mainFragment!=null){
        transaction.hide(mainFragment);
    }
    if(moreFragment!=null){
        transaction.hide(moreFragment);
    }
    if(mineFragment!=null){
        transaction.hide(mineFragment);
    }
}


@Override
public void onClick(View v) {
    initImageText();
    switch (v.getId()){
        case R.id.main_layout:
            setSelect(0);
            main_imageview.setImageResource(R.drawable.main2);
            main_textview.setTextColor(Color.parseColor("#707070"));
            break;

            mine_textview.setTextColor(Color.parseColor("#707070"));
            break;
    }
}

//初始化图片和文字(未点击自定义的Tab下样式)
private void initImageText() {
    main_imageview.setImageResource(R.drawable.main1);
    more_imageview.setImageResource(R.drawable.more1);
    mine_imageview.setImageResource(R.drawable.my1);

    main_textview.setTextColor(Color.parseColor("#dfdfdf"));
    more_textview.setTextColor(Color.parseColor("#dfdfdf"));
    mine_textview.setTextColor(Color.parseColor("#dfdfdf"));
}

}

MoreFragment
重点获取Fragmment子管理器用到getChildFragment()
