Android实现多个按钮切换,android实现点击按钮切换不同的fragment布局

本文实例为大家分享了android点击按钮切换不同布局的具体代码&＃xff0c;供大家参考&＃xff0c;具体内容如下

先上效果图&＃xff1a;

如图所示&＃xff0c;实现点击下面的按钮切换不同的fragment布局&＃xff1b;

不说了&＃xff0c;先上主MainActivity代码&＃xff1a;

MainActivity.java:

package com.example.xh.twostylefragment;

import android.content.Intent;

import android.os.Bundle;

import android.support.v4.app.FragmentTransaction;

import android.support.v7.app.AppCompatActivity;

import android.view.View;

import android.widget.Button;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

//定义5个fragment

private MyFragment f1;

private MyFragment2 f2;

private MyFragment3 f3;

private MyFragment4 f4;

private MyFragment5 f5;

//定义底部5个按钮

private Button foot1;

private Button foot2;

private Button foot3;

private Button foot4;

private Button foot5;

int i &＃61; 0;

&＃64;Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

foot1 &＃61; (Button) findViewById(R.id.btn1);//注册按钮

foot2 &＃61; (Button) findViewById(R.id.btn2);

foot3 &＃61; (Button) findViewById(R.id.btn3);

foot4 &＃61; (Button) findViewById(R.id.btn4);

foot5 &＃61; (Button) findViewById(R.id.btn5);

foot1.setOnClickListener(this);//对按钮设置监听

foot2.setOnClickListener(this);

foot3.setOnClickListener(this);

foot4.setOnClickListener(this);

foot5.setOnClickListener(this);

//第一次初始化首页默认显示第一个fragment

initFragment1();

}

//显示第一个fragment

private void initFragment1(){

//开启事务&＃xff0c;fragment的控制是由事务来实现的

FragmentTransaction transaction &＃61; getSupportFragmentManager().beginTransaction();

//第一种方式(add)&＃xff0c;初始化fragment并添加到事务中&＃xff0c;如果为null就new一个

if(f1 &＃61;&＃61; null){

f1 &＃61; new MyFragment();

transaction.add(R.id.main_frame_layout, f1);

}

//隐藏所有fragment

hideFragment(transaction);

//显示需要显示的fragment

transaction.show(f1);

//第二种方式(replace)&＃xff0c;初始化fragment

// if(f1 &＃61;&＃61; null){

// f1 &＃61; new MyFragment("首页");

// }

// transaction.replace(R.id.main_frame_layout, f1);

//提交事务

transaction.commit();

}

//显示第二个fragment

private void initFragment2(){

FragmentTransaction transaction &＃61; getSupportFragmentManager().beginTransaction();

if(f2 &＃61;&＃61; null){

f2 &＃61; new MyFragment2();

transaction.add(R.id.main_frame_layout,f2);

}

hideFragment(transaction);

transaction.show(f2);

// if(f2 &＃61;&＃61; null) {

// f2 &＃61; new MyFragment("分类");

// }

// transaction.replace(R.id.main_frame_layout, f2);

transaction.commit();

}

//显示第三个fragment

private void initFragment3(){

FragmentTransaction transaction &＃61; getSupportFragmentManager().beginTransaction();

if(f3 &＃61;&＃61; null){

f3 &＃61; new MyFragment3();

transaction.add(R.id.main_frame_layout,f3);

}

hideFragment(transaction);

transaction.show(f3);

// if(f3 &＃61;&＃61; null) {

// f3 &＃61; new MyFragment("发现");

// }

// transaction.replace(R.id.main_frame_layout, f3);

transaction.commit();

}

private void initFragment4(){

FragmentTransaction transaction &＃61; getSupportFragmentManager().beginTransaction();

if(f4 &＃61;&＃61; null){

f4 &＃61; new MyFragment4();

transaction.add(R.id.main_frame_layout,f4);

}

hideFragment(transaction);

transaction.show(f4);

// if(f4 &＃61;&＃61; null) {

// f4 &＃61; new MyFragment("购物车");

// }

// transaction.replace(R.id.main_frame_layout, f4);

transaction.commit();

}

private void initFragment5(){

FragmentTransaction transaction &＃61; getSupportFragmentManager().beginTransaction();

if(f5 &＃61;&＃61; null){

f5 &＃61; new MyFragment5();

transaction.add(R.id.main_frame_layout,f5);

}

hideFragment(transaction);

transaction.show(f5);

// if(f5 &＃61;&＃61; null) {

// f5 &＃61; new MyFragment("我的);

// }

// transaction.replace(R.id.main_frame_layout, f5);

transaction.commit();

}

//隐藏所有的fragment

private void hideFragment(FragmentTransaction transaction){

if(f1 !&＃61; null){

transaction.hide(f1);

}

if(f2 !&＃61; null){

transaction.hide(f2);

}

if(f3 !&＃61; null){

transaction.hide(f3);

}

if(f4 !&＃61; null){

transaction.hide(f4);

}

if(f5 !&＃61; null){

transaction.hide(f5);

}

}

&＃64;Override

public void onClick(View v) {//点击哪个按钮就显示哪个fragment;

if(v &＃61;&＃61; foot1){

initFragment1();

}else if(v &＃61;&＃61; foot2){

initFragment2();

}else if(v &＃61;&＃61; foot3){

initFragment3();

}else if(v &＃61;&＃61; foot4){

initFragment4();

}else if(v &＃61;&＃61; foot5){

initFragment5();

}

}

}

大家需要创建5个fragment&＃xff0c;还有对应的xml文件&＃xff0c;这里我给大家展示我创建的MyFragment4.java&＃xff1a;

package com.example.xh.twostylefragment;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

/**

* Created by Administrator on 2016/7/8.

*/

public class MyFragment4 extends Fragment {

&＃64;Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

View view &＃61; LayoutInflater.from(getActivity()).inflate(R.layout.shoppingcar,container,false);//用view保存shoppingcar.xml布局&＃xff0c;大家可以

return view; //自己创建一个xml.

}

}

差不多就是这样的了&＃xff0c;有问题大家可以提出来。

以上就是本文的全部内容&＃xff0c;希望对大家的学习有所帮助&＃xff0c;也希望大家多多支持脚本之家。
