使用RadioGroup及Fragment来实现底部Tab效果 (AS版本)

使用RadioGroup及Fragment来实现底部Tab效果 (AS版本)

底部导航栏，这是日常开发里面经常用到的，如此我把之前项目里面剥离出来，例子比较简单，希望又需要的的朋友可以下载下来



MainActivity

package com.yuekog;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.widget.RadioGroup;

import com.yuekog.ui.fragment.FragOperManager;
import com.yuekog.ui.fragment.Fragment01;
import com.yuekog.ui.fragment.Fragment02;
import com.yuekog.ui.fragment.Fragment03;
import com.yuekog.ui.fragment.Fragment04;

public class MainActivity extends FragmentActivity implements RadioGroup.OnCheckedChangeListener {

private FragOperManager manager;
private RadioGroup rdoBtn;
private Fragment01 fragment01;
private Fragment02 fragment02;
private Fragment03 fragment03;
private Fragment04 fragment04;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragment01 = new Fragment01();
fragment02 = new Fragment02();
fragment03 = new Fragment03();
fragment04 = new Fragment04();
manager = new FragOperManager(this, R.id.fragment_container);
manager.chReplaceFrag(fragment01, "fragment01", false);
rdoBtn = (RadioGroup) findViewById(R.id.main_rg);
rdoBtn.setOnCheckedChangeListener(this);
}

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.rb0:
manager.chReplaceFrag(fragment01, "fragment01", false);
break;
case R.id.rb1:
manager.chReplaceFrag(fragment02, "fragment02", false);
break;
case R.id.rb2:
manager.chReplaceFrag(fragment03, "fragment03", false);
break;
case R.id.rb3:
manager.chReplaceFrag(fragment04, "fragment04", false);
break;
}
}

}

activity_main.xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:background="@android:color/white"
android:layout_height="match_parent">

<FrameLayout
android:id="@+id/fragment_container"
android:layout_height="0dip"
android:layout_weight="1"
android:layout_width="match_parent"/>

<RadioGroup
android:id="@+id/main_rg"
android:layout_height="50dip"
android:background="@mipmap/tab_main_bg"
android:layout_width="match_parent"
android:orientation="horizontal">
<RadioButton

android:drawableTop="@drawable/tab_01_bg"
android:text="@string/text_tab_01"/>
<RadioButton

<RadioButton
android:id="@+id/rb3"
style="@style/main_tab_style"
android:drawableTop="@drawable/tab_04_bg"
android:text="@string/text_tab_04"/>
</RadioGroup>

</LinearLayout>

style=”@style/main_tab_style”

<style name="main_tab_style">
<item name="android:layout_height">match_parent</item>
<item name="android:layout_width">0dip</item>
<item name="android:layout_weight">1</item>
<item name="android:button">@null</item>
<item name="android:paddingTop">5dip</item>
<item name="android:textSize">11dip</item>
<item name="android:paddingBottom">5dip</item>
<item name="android:gravity">center</item>
<item name="android:textColor">@color/main_tab_color_bg</item>
</style>

各个Fragment

public class Fragment01 extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreateView(inflater, container, savedInstanceState);
return inflater.inflate(R.layout.fragment_01, null);
}

}

这里只是列出一个Fragement，其实几个都是类似
