在代码中动态绑定TabHost内容的两种方法(Android)

TabHost是多标签控件，包含多个Tab，可在一个页面显示多种布局。

使用方法一：

新建Activity继承TabActivity，利用其方法生成TabHost

TabUse1.java

package org.tabhost;
import org.tabhost.R;
import android.app.TabActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.*;
public class TabUse1 extends TabActivity {
private TabHost tabhost;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tabhost=getTabHost();
LayoutInflater layoutInflater=LayoutInflater.from(this);

layoutInflater.inflate(R.layout.tab1, tabhost.getTabContentView());
FrameLayout frameLayout=(FrameLayout) findViewById(R.id.tab1);
TextView textView=new TextView(this);
textView.setText("tab1-TextView");
frameLayout.addView(textView);
TabHost.TabSpec tabSpec1=tabhost.newTabSpec("tab-1");
tabSpec1.setIndicator("tab-1", null);
tabSpec1.setContent(R.id.tab1);
tabhost.addTab(tabSpec1);

layoutInflater.inflate(R.layout.tab2, tabhost.getTabContentView());
LinearLayout lineLayout=(LinearLayout) findViewById(R.id.tab2);
Button btn=new Button(this);
btn.setText("tab2-Button");
lineLayout.addView(btn);
TabHost.TabSpec tabSpec2=tabhost.newTabSpec("tab-2");
tabSpec2.setIndicator("tab-2", null);
tabSpec2.setContent(R.id.tab2);
tabhost.addTab(tabSpec2);
}
}

tab1.xml

<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/tab1"
>
</FrameLayout>

tab2.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:id="@+id/tab2">
</LinearLayout>

方法二：

通过界面定义文件生成TabHost

TabTest.java

package org.tabhost;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TabHost;
public class TabTest extends Activity {
/** Called when the activity is first created. */
/** Called when the activity is first created. */
private TabHost tabHost;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try{
tabHost = (TabHost) this.findViewById(R.id.TabHost01);
tabHost.setup();

tabHost.addTab(tabHost.newTabSpec("tab_1")
.setContent(new TabFactory(this))
.setIndicator("TAB1"));
tabHost.addTab(tabHost.newTabSpec("tab_2")
.setContent(new TabFactory(this))
.setIndicator("TAB2"));
tabHost.addTab(tabHost.newTabSpec("tab_3")
.setContent(new TabFactory(this))
.setIndicator("TAB3"));
tabHost.setCurrentTab(1);
}catch(Exception ex){
ex.printStackTrace();
}

}

TabFactory.java，在此类中可以动态生成各Tab中的控件

package org.tabhost;
import android.content.Context;
import android.view.View;
import android.widget.EditText;
import android.widget.TabHost.TabContentFactory;
public class TabFactory implements TabContentFactory {
private Context con;
public TabFactory(Context c){
con=c;
}
@Override
public View createTabContent(String arg0) {
EditText text=new EditText(con);
text.setText("text1");
return text;
}
}

main.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TabHost01" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
android:orientation="vertical" android:layout_height="fill_parent">
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

</FrameLayout>
</LinearLayout>
</TabHost>
