Android 底部TabActivity（2）——ActivityGroup

标签：des   android   style   blog   http   io   ar   color   os   

今天这篇文章记述一下页面顶部底部上下均有Tab标签页的特殊需求！使用了过时的ActivityGroup。

再看一下整个Project的结构，如下

下面逐一介绍一下实现过程，一贯风格，具体实现还是看注释吧，代码也不是很多，就不啰嗦了。

step1：首先是主界面MainActivity.java

package sun.geoffery.tabtopbottom;

import android.app.ActivityGroup;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Window;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.widget.TabWidget;
import android.widget.TextView;

 */
public class MainActivity extends ActivityGroup {
	// 定义一个TabHost控件
	private TabHost mTabHost;

	public void onCreate(Bundle savedInstanceState) {
		
		// 设置隐藏标题栏
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		// 获取TabHost布局
		mTabHost = (TabHost) findViewById(R.id.tabhost);
		mTabHost.setup(this.getLocalActivityManager());

		TabSpec _tab;
		
		_tab = mTabHost.newTabSpec("home");
		_tab.setIndicator("首页", getResources().getDrawable(R.drawable.ic_launcher));
		_tab.setContent(new Intent(this, HomeActivity.class));
		mTabHost.addTab(_tab);

		_tab = mTabHost.newTabSpec("order");
		_tab.setIndicator("订单", getResources().getDrawable(R.drawable.ic_launcher));
		_tab.setContent(new Intent(this, OrderActivity.class));
		mTabHost.addTab(_tab);

		_tab = mTabHost.newTabSpec("wallet");
		_tab.setIndicator("钱包", getResources().getDrawable(R.drawable.ic_launcher));
		_tab.setContent(new Intent(this, WalletActivity.class));
		mTabHost.addTab(_tab);

		// 设置第一个标签页被选中
		mTabHost.setCurrentTab(0);

		TabWidget tabWidget = mTabHost.getTabWidget();
		
		for (int i = 0; i < tabWidget.getChildCount(); i++) {
			TextView tv = (TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);
			tv.setTextColor(Color.LTGRAY);// 设置Tab栏字体的颜色
		}
	}
}

step2：主页面对应的布局文件

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

    <!-- 选项卡布局必须要用TabHost -->
    <TabHost
        android:id="@+id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <!-- 镶嵌线性布局 -->
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical" >

            <!-- 帧布局 -->
            <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"/>
            
            <!-- TabWidget是Tab标签的使用 -->
            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_weight="0" 
                android:background="#404040"/>
        </LinearLayout>
    </TabHost>

</LinearLayout>

package sun.geoffery.tabtopbottom;

import android.app.Activity;
import android.os.Bundle;

public class HomeActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }
}
