Android Activity中实现Fragment切换功能效果

一个最简单的Activity中实现Fragment切换功能效果：

一.效果图：

二.快速实现：

一个Activity中添加多个Fragment进行切换实现相应的功能需求逻辑，比如在activity中有三个按钮切换fragment界面，按钮1和按钮二都是点击之后直接切换到对应的Fragment，按钮3则是弹出一个弹框出来，然后点击弹框中的按钮再进行切换到对应的Fragment。

1.主函数代码：

import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import android.widget.ListView;

}

2.主函数布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/colorPrimary"android:orientation="vertical"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="50dp"><Buttonandroid:id="@+id/bt_one"android:text="一"android:layout_width="wrap_content"android:layout_height="wrap_content" /><Buttonandroid:id="@+id/bt_two"android:text="二"android:layout_width="wrap_content"android:layout_height="wrap_content" /><Buttonandroid:id="@+id/bt_three"android:text="三"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout><FrameLayoutandroid:id="@+id/fl"android:layout_width="match_parent"android:layout_height="match_parent"></FrameLayout>
</LinearLayout>

3.FlyFragment.class:

package com.example.qd.douyinwu.fragment;import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;import com.example.qd.douyinwu.R;public class FlyFragment extends Fragment{@Overridepublic void onActivityCreated(@Nullable Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);}@Overridepublic void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {super.onViewCreated(view, savedInstanceState);}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.fragment_fly,container,false);
//        TextView mTextView = (TextView) view.findViewById(R.id.tv_fragment_content);
//        mTextView.setText("Fragment2");
//        mTextView.setOnClickListener(this);
//        Button mButton = (Button) view.findViewById(R.id.btn_toggle_fragment);
//        mButton.setOnClickListener(this);return view;}
}

4.fragment_fly.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:id="@+id/tv_content"android:text="我是一"android:layout_gravity="center"android:gravity="center"android:textSize="25sp"android:layout_width="match_parent"android:layout_height="wrap_content" />
</LinearLayout>

5.Fragment都是类似的就不全部贴出了，直接复制改下名字就可以：

TestFragment.class

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;import com.example.qd.douyinwu.R;public class TestFragment extends Fragment{@Overridepublic void onActivityCreated(@Nullable Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);}@Overridepublic void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {super.onViewCreated(view, savedInstanceState);}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.fragment_hight,container,false);TextView mTextView = (TextView) view.findViewById(R.id.tv_content);mTextView.setText("我是三");
//        mTextView.setOnClickListener(this);
//        Button mButton = (Button) view.findViewById(R.id.btn_toggle_fragment);
//        mButton.setOnClickListener(this);return view;}
}
