点击 tab 时调用 activity 的问题

用什么方法可以在 tabs 上添加 setOnLongClickListener？或者点击一个 tab 时，可以调用一个 activity。长时间点击相同的 tab 时，调用一个不同的 activity?

public class HelloTabWidget extends TabActivity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        Resources res = getResources();         TabHost tabHost = getTabHost();         TabHost.TabSpec spec;        Intent intent;          // Create an Intent to launch an Activity for the tab (to be reused)        intent = new Intent().setClass(this ArtistsActivity.class);        // Initialize a TabSpec for each tab and add it to the TabHost        spec = tabHost.newTabSpec(""artists"").setIndicator(""Artists""                          res.getDrawable(R.drawable.ic_tab_artists))                      .setContent(intent);        tabHost.addTab(spec);        tabHost.setOnLongClickListener(new OnLongClickListener(){            @Override            public boolean onLongClick(View v) {                // TODO Auto-generated method stub////                Intent i=new Intent(getApplicationContext()LongClickStuff.class);//              startActivity(i);//              return true;                Toast.makeText(getApplicationContext()into long click"" Toast.LENGTH_LONG).show();                return false;            }        });        // Do the same for the other tabs        intent = new Intent().setClass(this AlbumsActivity.class);        spec = tabHost.newTabSpec(""albums"").setIndicator(""Albums""                          res.getDrawable(R.drawable.ic_tab_albums))                      .setContent(intent);        tabHost.addTab(spec);        intent = new Intent().setClass(this SongsActivity.class);        spec = tabHost.newTabSpec(""songs"").setIndicator(""Songs""                          res.getDrawable(R.drawable.ic_tab_songs))                      .setContent(intent);        tabHost.addTab(spec);        tabHost.setCurrentTab(2);    }}

解决方案

 TabHost tabHost = getTabHost();  tabHost.setOnLongClickListener(new OnLongClickListener(){}

看上面这两行，说明你的长按事件监听器是给TabHost对象绑定的，你改为为每个 TabHost.TabSpec （单个选项卡）绑定setOnLongClickListener()，或者为代表单个选项卡的View绑定长按事件监听器，你试试看。

解决方案二：
长时间点击Tab的时候 测试并验证哪个Tab的索引值是“0”

tabHost.getTabWidget().getChildAt(0).setOnLongClickListener(new OnLongClickListener() {    public boolean onLongClick(View v) {        Toast.makeText(getApplicationContext()long click"" 1).show();        return true;    }});
