1.MainActivity代码:
(也就是TabsFrame)
package com.example.frametabhost;
import com.example.function.WebGo;
import com.example.licaizhuanjia.MainActivity;
import com.example.licaizhuanjia.R;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTabHost;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost.TabSpec;
import android.widget.TextView;
public class TabsFrame extends FragmentActivity {
private FragmentTabHost fragmentTabHost;
private String texts[] = { "开始", "好友", "群组", "更多" };
private int p_w_picpathButton[] = { R.drawable.selector1,
R.drawable.selector2,
R.drawable.selector3,
R.drawable.selector4};
private Class fragmentArray[] = {Page1.class,
Page2.class,
Page3.class,
Page4.class};
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabsframe);
// 实例化tabhost
fragmentTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
fragmentTabHost.setup(this, getSupportFragmentManager(),R.id.maincontent);
for (int i = 0; i < texts.length; i++) {
TabSpec spec=fragmentTabHost.newTabSpec(texts[i]).setIndicator(getView(i));
fragmentTabHost.addTab(spec, fragmentArray[i], null);
//设置背景(必须在addTab之后,由于需要子节点(底部菜单按钮)否则会出现空指针异常)
fragmentTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.bgselector);
//背景替换
}
}
private View getView(int i) {
//取得布局实例
View view=View.inflate(TabsFrame.this, R.layout.tabcontent, null);
//取得布局对象
ImageView p_w_picpathView=(ImageView) view.findViewById(R.id.p_w_picpath);
TextView textView=(TextView) view.findViewById(R.id.text);
//设置图标
p_w_picpathView.setImageResource(p_w_picpathButton[i]);
//设置标题
textView.setText(texts[i]);
return view;
}
public boolean onKeyDown(int KeyCode,KeyEvent Event){
if(KeyCode==KeyEvent.KEYCODE_BACK){
Intent intent=new Intent(TabsFrame.this,MainActivity.class);
startActivity(intent);
finish();
}
return true;
}
}
2. 然后是4个Page,代码都一样
public class Page1 extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
return inflater.inflate(R.layout.page1, null);
}
}
主要代码就是这些
然后是xml布局文件
3.在tabsframe里
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<!-- 存放主要页面内容 -->
<FrameLayout
android:id="@+id/maincontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
<!-- 底层菜单 -->
<android.support.v4.app.FragmentTabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/tab_bg" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0" >
</FrameLayout>
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
4.tabcontent.xml里是底部标签栏的图标
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ImageView
android:id="@+id/p_w_picpath"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
/>
<TextView
android:id="@+id/text"
android:padding="2dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@android:color/white"
/>
</LinearLayout>
5.在selector1,2,3,4里(写在drawable文件夹里)
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/tab1" android:state_selected="true"></item>
<item android:drawable="@drawable/tab1_hb"></item>
</selector>
6.在bgselector.xml里
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/tabsbg" android:state_pressed="true"></item>
<item android:drawable="@drawable/tabsbg" android:state_selected="true"></item>
</selector>
7.4个page的xml(4个都一样的代码)。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/tabframe1"
>
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="22dp"
android:text="正在开发中。。。。。"
android:textSize="20dp" />
</RelativeLayout>
