I have downloaded a code from internet of tab . The adding part of code for tab is as following:
private void setTabs()
{
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
addTab("Home", TAG_1, createTabDrawable(R.drawable.home), R.id.text_view_home,HomeActivity.class);
addTab("Search", TAG_2, createTabDrawable(R.drawable.search), R.id.text_view_search, SearchActivity.class);
addTab("Favourites", TAG_3, createTabDrawable(R.drawable.star), R.id.text_view_favourites,HomeActivity.class);
addTab("Settings", TAG_4, createTabDrawable(R.drawable.settings), R.id.text_view_settings, SearchActivity.class);
}
And the function of addTab is as following :
private void addTab(String label, String tag, Drawable drawable, int id, Class<?> c) {
TabHost.TabSpec spec = mTabHost.newTabSpec(tag);
spec.setIndicator(createTabIndicator(label, drawable));
// spec.setContent(id);
Intent intent = new Intent(this, c);
spec.setContent(intent);
mTabHost.addTab(spec);
}
The exception is as following :

The problem is removed if the addTab function is as following :
private void addTab(String label, String tag, Drawable drawable, int id, Class<?> c) {
TabHost.TabSpec spec = mTabHost.newTabSpec(tag);
spec.setIndicator(createTabIndicator(label, drawable));
spec.setContent(id);
// Intent intent = new Intent(this, c);
// spec.setContent(intent);
mTabHost.addTab(spec);
}
I have just added the line of intent . But after adding this line , I have got exception . How can I do that ? Plz help me .
