Fragment实现不支持左右滑动的Tab

主要思想：顶部标题top.xml，中间Fragment，底部Tab导航。

top.xml具体实现：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="45dp"
android:background="@drawable/title_bar"
android:gravity="center"
android:orientation="vertical" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="微信"
android:textColor="#ffffff"
android:textSize="20sp"
android:textStyle="bold" />

</LinearLayout>

 

 

bottom.xml具体实现：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dp"
android:background="@drawable/bottom_bar"
android:orientation="horizontal" >

<LinearLayout
android:id="@+id/id_tab_weixin"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >

<ImageButton
android:id="@+id/id_tab_weixin_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:clickable="false"
android:src="@drawable/tab_weixin_pressed" />

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="微信"
android:textColor="#ffffff" />
</LinearLayout>

<LinearLayout
android:id="@+id/id_tab_frd"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >

<ImageButton
android:id="@+id/id_tab_frd_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:clickable="false"
android:src="@drawable/tab_find_frd_normal" />

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="朋友"
android:textColor="#ffffff" />
</LinearLayout>

<LinearLayout
android:id="@+id/id_tab_address"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >

<ImageButton
android:id="@+id/id_tab_address_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:clickable="false"
android:src="@drawable/tab_address_normal" />

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="通讯录"
android:textColor="#ffffff" />
</LinearLayout>

<LinearLayout
android:id="@+id/id_tab_settings"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >

<ImageButton
android:id="@+id/id_tab_settings_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:clickable="false"
android:src="@drawable/tab_settings_normal" />

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="设置"
android:textColor="#ffffff" />
</LinearLayout>

</LinearLayout>

 

 

activity_main.xml具体实现：

<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:orientation="vertical" >

<include layout="@layout/top" />

<FrameLayout 
android:id="@+id/id_content"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
></FrameLayout>

<include layout="@layout/bottom" />

</LinearLayout>

 

 

WeixinFragment.java具体实现：

package com.imooc.tab02;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class WeixinFragment extends Fragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.tab01, container, false);
}
}

 

另外3个Fragment的实现类似，此处不再赘述。

MainActivity.java具体实现：

package com.imooc.tab02;

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

private Fragment mTab01;
private Fragment mTab02;
private Fragment mTab03;
private Fragment mTab04;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

setSelect(0);
}

private void initEvent()
{

}

mTabSettings = (LinearLayout) findViewById(R.id.id_tab_settings);

mImgWeixin = (ImageButton) findViewById(R.id.id_tab_weixin_img);
mImgFrd = (ImageButton) findViewById(R.id.id_tab_frd_img);
mImgAddress = (ImageButton) findViewById(R.id.id_tab_address_img);
mImgSettings = (ImageButton) findViewById(R.id.id_tab_settings_img);
}

private void setSelect(int i)
{
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
hideFragment(transaction);
// 把图片设置为亮的
// 设置内容区域
switch (i)
{
case 0:
if (mTab01 == null)
{
mTab01 = new WeixinFragment();
transaction.add(R.id.id_content, mTab01);
} else
{
transaction.show(mTab01);
}
mImgWeixin.setImageResource(R.drawable.tab_weixin_pressed);
break;
case 1:
if (mTab02 == null)
{
mTab02 = new FrdFragment();transaction.add(R.id.id_content, mTab02);
} else

transaction.show(mTab02);

}
mImgFrd.setImageResource(R.drawable.tab_find_frd_pressed);
break;
case 2:
if (mTab03 == null)
{
mTab03 = new AddressFragment();
transaction.add(R.id.id_content, mTab03);
} else
{
transaction.show(mTab03);
}
mImgAddress.setImageResource(R.drawable.tab_address_pressed);
break;
case 3:
if (mTab04 == null)
{
mTab04 = new SettingFragment();
transaction.add(R.id.id_content, mTab04);
} else
{
transaction.show(mTab04);
}
mImgSettings.setImageResource(R.drawable.tab_settings_pressed);
break;

default:
break;
}

transaction.commit();
}

private void hideFragment(FragmentTransaction transaction)
{
if (mTab01 != null)
{
transaction.hide(mTab01);
}
if (mTab02 != null)
{
transaction.hide(mTab02);
}
if (mTab03 != null)
{
transaction.hide(mTab03);
}
if (mTab04 != null)
{
transaction.hide(mTab04);
}
}

@Override
public void onClick(View v)
{
resetImgs();
switch (v.getId())
{
case R.id.id_tab_weixin:
setSelect(0);
break;
case R.id.id_tab_frd:
setSelect(1);
break;
case R.id.id_tab_address:
setSelect(2);
break;
case R.id.id_tab_settings:
setSelect(3);
break;

default:
break;
}
}

/**

*/
private void resetImgs()
{
mImgWeixin.setImageResource(R.drawable.tab_weixin_normal);
mImgFrd.setImageResource(R.drawable.tab_find_frd_normal);
mImgAddress.setImageResource(R.drawable.tab_address_normal);
