我有第三个标签的标签活动
TabMainActivity
public class TabMainActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost();
Intent it=getIntent();
int num_tab=it.getIntExtra("num_tab", 0);
// Tab1
TabSpec photospec = tabHost.newTabSpec("Tab1");
// setting Title and Icon for the Tab
photospec.setIndicator("Tab1", getResources().getDrawable(R.drawable.icon_photos_tab));
Intent photosIntent = new Intent(this, PhotosActivity.class);
photospec.setContent(photosIntent);
// Tab2
TabSpec songspec = tabHost.newTabSpec("Tab2");
songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));
Intent songsIntent = new Intent(this, SongsActivity.class);
songspec.setContent(songsIntent);
// Tab3
TabSpec videospec = tabHost.newTabSpec("Tab3");
videospec.setIndicator("Videos", getResources().getDrawable(R.drawable.icon_videos_tab));
Intent videosIntent = new Intent(this, VideosActivity.class);
videospec.setContent(videosIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(photospec); // Adding photos tab
tabHost.addTab(songspec); // Adding songs tab
tabHost.addTab(videospec); // Adding videos tab
tabHost.setCurrentTab(num_tab);
}
}
Tab1:Activity1.java
public class Activity1 extends Activity {
@Override
public void onCreate(Bundle circle)
{
super.onCreate(circle);
setContentView(R.layout.layout1);
Toast.makeText(getBaseContext(), "This is tab1",Toast.LENGTH_LONG).show();
}
}
Tab2:Activity2.java
public class Activity2 extends Activity {
@Override
public void onCreate(Bundle circle)
{
super.onCreate(circle);
setContentView(R.layout.layout1);
}
}
Tab3:Activity3.java
public class Activity3 extends Activity {
@Override
public void onCreate(Bundle circle)
{
super.onCreate(circle);
setContentView(R.layout.layout1);
Button button3=(Button)findViewbyId(R.id.button3);
button3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Activity3.this.finish();
Intent it=new Intent(Activity3.this,TabMainActivity.class);
it.putExtra("num_tab",2);
startActivity(it);
}
});
}
}
现在,如果在tab3中我点击button3 ..它总是在tab1中显示操作代码(显示吐司作为代码)..然后再打开tab3。我只想再打开tab3但不要在tab1中操作代码。 我该怎么办?

您可以尝试在“prepare()”中添加tab而不是“onCreate()”,但仍然可以在“onCreate()”中添加setCurrentTab。
