安卓精美底部导航栏的实现TabHost

先看效果图：

先来看布局文件：maintabs.xml

主要的实现文件：MainTabActivity.java

package com.andyidea.tabdemo;

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;
import android.widget.CompoundButton;
import android.widget.RadioButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.TabHost;

public class MainTabActivity extends TabActivity implements OnCheckedChangeListener{
	
	private TabHost mTabHost;
	private Intent mAIntent;
	private Intent mBIntent;
	private Intent mCIntent;
	private Intent mDIntent;
	private Intent mEIntent;
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.maintabs);

	}

}
