现在很多android的应用都采用底部导航栏的功能,这样可以使得用户在使用过程中随意切换不同的页面,现在采用TabHost组件来自定义一个底部的导航栏的功能。

Image

其中各个类的作用以及资源文件就不详细解释了,还有资源图片(在该Demo中借用了其它应用程序的资源图片)也不提供了,大家可以自行更换自己需要的资源图片。直接上各个布局文件或各个类的代码:

[1]  res/layout目录下的 maintabs.xml 源码:

<?xml version="1.0" encoding="UTF-8"?>
<TabHost android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent">
<FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="0.0dip" android:layout_weight="1.0" />
<TabWidget android:id="@android:id/tabs" android:visibility="gone" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0.0" />
<RadioGroup 
android:gravity="center_vertical" android:layout_gravity="bottom" android:orientation="horizontal" android:id="@id/main_radio" android:background="@drawable/maintab_toolbar_bg" 
android:layout_width="fill_parent" android:layout_height="wrap_content">
<RadioButton android:id="@id/radio_button0" android:layout_marginTop="2.0dip" android:text="@string/main_home" android:drawableTop="@drawable/icon_1_n" style="@style/main_tab_bottom" />
<RadioButton android:id="@id/radio_button1" android:layout_marginTop="2.0dip" android:text="@string/main_news" android:drawableTop="@drawable/icon_2_n" style="@style/main_tab_bottom" />
<RadioButton android:id="@id/radio_button2" android:layout_marginTop="2.0dip" android:text="@string/main_manage_date" android:drawableTop="@drawable/icon_3_n" style="@style/main_tab_bottom" />
<RadioButton android:id="@id/radio_button3" android:layout_marginTop="2.0dip" android:text="@string/main_friends" android:drawableTop="@drawable/icon_4_n" style="@style/main_tab_bottom" />
<RadioButton android:id="@id/radio_button4" android:layout_marginTop="2.0dip" android:text="@string/more" android:drawableTop="@drawable/icon_5_n" style="@style/main_tab_bottom" />
</RadioGroup>
</LinearLayout>
</TabHost>

[2] res/drawable 下的 home_btn_bg.xml 源码:

<?xml version="1.0" encoding="UTF-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_enabled="true" android:state_pressed="false" android:drawable="@drawable/home_btn_bg_s" />
<item android:state_enabled="true" android:state_pressed="true" android:drawable="@drawable/home_btn_bg_s" />
<item android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/home_btn_bg_d" />
<item android:drawable="@drawable/transparent" />
</selector>

[3] res/values 下的源码:

</style>

</resources>

[4] src/com.andyidea.tabdemo包下面各个UI界面类源码:MainTabActivity.java源码:

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);

this.mAIntent = new Intent(this,AActivity.class);
this.mBIntent = new Intent(this,BActivity.class);
this.mCIntent = new Intent(this,CActivity.class);
this.mDIntent = new Intent(this,DActivity.class);
this.mEIntent = new Intent(this,EActivity.class);

((RadioButton) findViewById(R.id.radio_button0))
.setOnCheckedChangeListener(this);
((RadioButton) findViewById(R.id.radio_button1))
.setOnCheckedChangeListener(this);
((RadioButton) findViewById(R.id.radio_button2))
.setOnCheckedChangeListener(this);
((RadioButton) findViewById(R.id.radio_button3))
.setOnCheckedChangeListener(this);
((RadioButton) findViewById(R.id.radio_button4))
.setOnCheckedChangeListener(this);

setupIntent();
}

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
switch (buttonView.getId()) {
case R.id.radio_button0:
this.mTabHost.setCurrentTabByTag("A_TAB");
break;
case R.id.radio_button1:
this.mTabHost.setCurrentTabByTag("B_TAB");
break;
case R.id.radio_button2:
this.mTabHost.setCurrentTabByTag("C_TAB");
break;
case R.id.radio_button3:
this.mTabHost.setCurrentTabByTag("D_TAB");
break;
case R.id.radio_button4:
this.mTabHost.setCurrentTabByTag("MORE_TAB");
break;
}
}

}

private void setupIntent() {
this.mTabHost = getTabHost();
TabHost localTabHost = this.mTabHost;

localTabHost.addTab(buildTabSpec("A_TAB", R.string.main_home,
R.drawable.icon_1_n, this.mAIntent));

localTabHost.addTab(buildTabSpec("B_TAB", R.string.main_news,
R.drawable.icon_2_n, this.mBIntent));

localTabHost.addTab(buildTabSpec("C_TAB",
R.string.main_manage_date, R.drawable.icon_3_n,
this.mCIntent));

localTabHost.addTab(buildTabSpec("D_TAB", R.string.main_friends,
R.drawable.icon_4_n, this.mDIntent));

localTabHost.addTab(buildTabSpec("MORE_TAB", R.string.more,
R.drawable.icon_5_n, this.mEIntent));

}

private TabHost.TabSpec buildTabSpec(String tag, int resLabel, int resIcon,
final Intent content) {
return this.mTabHost.newTabSpec(tag).setIndicator(getString(resLabel),
getResources().getDrawable(resIcon)).setContent(content);
}
}

其中 AActivity.java 与 BActivity.java ,CActivity.java ,DActivity.java ,EActivity.java 中的源码都一样,比较简单,大家自己设置即可

最后,大家别忘了在 AndroidManifest.xml 文件中注册各个 Activity 组件哦。好了,现在我们看下我们程序运行的效果图:

到此就实现了一个比较流行的底部导航栏的功能了
