Fragment分別title顯示_Demo

主Activity代碼：

package com.example.fragmenttest10;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.View;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //調用切換Fragmnet方法
        changeFragmnet(new Fragment1());

    }

    //監聽的按鈕方法：
   public void weixinclick(View v){
       changeFragmnet(new Fragment1());

   }
   //監聽的按鈕方法：
   public void findclick(View v){
       changeFragmnet(new Fragment2());


   }
   //監聽的按鈕方法：
   public void meclick(View v){
       changeFragmnet(new Fragment3());
   }

   //切換fragment的方法
   public void changeFragmnet(Fragment fr){

       //第一步：得到fragment管理類
       FragmentManager manager = getSupportFragmentManager();
       //得到事務
       FragmentTransaction beginTransaction = manager.beginTransaction();
       //調用replace 添加fragment
       beginTransaction.replace(R.id.lincontent, fr);
       //提交
       beginTransaction.commit();

   }

}
