android自定义TabWidget样式

先看看效果图吧，个人觉得图标丑了点，不过还行，自己用PS做的



下面是全部代码和流程，一定要按流程顺序来，不然错误！

1.tabhost.xml

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

<RelativeLayout
android:id="@+id/relativelayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

<LinearLayout
android:id="@+id/tab1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>

<LinearLayout
android:id="@+id/tab2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>

<LinearLayout
android:id="@+id/tab3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>

<LinearLayout
android:id="@+id/tab4"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>

<LinearLayout
android:id="@+id/tab5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>

<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@drawable/tabwidget_bj" >
</TabWidget>
</RelativeLayout>

</TabHost>

2.tab_item_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >

<ImageView
android:id="@+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|top"
android:padding="3dp" />

<TextView
android:id="@+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|bottom"
android:textColor="#fff"
android:textSize="13sp"
style="bold"/>

</LinearLayout>

3.样式选择器selector：tab_item_style.xml，新建文件夹drawable，然后将该xml文件放进去

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/unpressed_bj" android:state_selected="false"/>
<item android:drawable="@drawable/pressed_bj" android:state_selected="true"/>

</selector>

4.java代码实现：MyTabHost.java

package com.example.androidtabhost4;

import android.os.Bundle;
import android.app.Activity;
import android.app.TabActivity;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost;
import android.widget.TextView;
import android.widget.TabHost.TabSpec;

public class MyTabHost extends TabActivity {

private TabHost tabHost;
private LayoutInflater layoutInflater;
String[] mTitle = new String[] { "首页", "留言", "评论", "收藏", "更多" };
int[] mIcon = new int[] { R.drawable.home, R.drawable.saying,
R.drawable.zan, R.drawable.collect, R.drawable.more };
int[] mTab = new int[] { R.id.tab1, R.id.tab2, R.id.tab3, R.id.tab4,
R.id.tab5 };

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabhost);
init();
}

public View getTabItemView(int i) {
// TODO Auto-generated method stub
View view = layoutInflater.inflate(R.layout.tab_item_view, null);
ImageView imageView = (ImageView) view.findViewById(R.id.imageview);
imageView.setImageResource(mIcon[i]);
TextView textView = (TextView) view.findViewById(R.id.textview);
textView.setText(mTitle[i]);
return view;
}

public void init() {
// TODO Auto-generated method stub
tabHost = getTabHost();
layoutInflater = LayoutInflater.from(this);
for (int i = 0; i < mTitle.length; i++) {
TabSpec tabSpec = tabHost.newTabSpec(mTitle[i])
.setIndicator(getTabItemView(i)).setContent(mTab[i]);
tabHost.addTab(tabSpec);
tabHost.getTabWidget().getChildAt(i)
.setBackgroundResource(R.drawable.tab_item_style);
tabHost.setup();
}
}

}
