Android编程之TabWidget选项卡用法实例分析

复制代码 mTabHost.setup();
4.2 主要代码

 

直接继承自Activity的代码

import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TabHost;
import android.widget.TextView;
public class TabDesignActivity extends Activity{
  private Context mContex = this;
  private TabHost mTabHost;
  private String TAB1 = "tab1";
  private String TAB2 = "tab2";
  private String TAB3 = "tab3";
  private String TAB4 = "tab4";
  private String TAB5 = "tab5";
  private List<LinearLayout> menuItemList;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tab_main);
    menuItemList = new ArrayList<LinearLayout>();
    mTabHost = (TabHost) findViewById(R.id.tabhost);
    mTabHost.setup();
    mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator(getMenuItem(R.drawable.tab1_ispressed, TAB1)).setContent(R.id.tab1));
    mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator(getMenuItem(R.drawable.tab2_ispressed, TAB2)).setContent(R.id.tab2));
    mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator(getMenuItem(R.drawable.tab3_ispressed, TAB3)).setContent(R.id.tab3));
    mTabHost.addTab(mTabHost.newTabSpec("tab4").setIndicator(getMenuItem(R.drawable.tab4_ispressed, TAB4)).setContent(R.id.tab4));
    mTabHost.addTab(mTabHost.newTabSpec("tab5").setIndicator(getMenuItem(R.drawable.tab5_ispressed, TAB5)).setContent(R.id.tab5));
  }
  public View getMenuItem(int imgID, String textID){
    LinearLayout ll = (LinearLayout)LayoutInflater.from(mContex).inflate(R.layout.tab_item, null);
    ImageView imgView = (ImageView)ll.findViewById(R.id.icon);
    imgView.setBackgroundResource(imgID);
    TextView textView = (TextView)ll.findViewById(R.id.name);
    textView.setText(textID);
    menuItemList.add(ll);
    return ll;
  }
}

继承自TabActivity的实现
