public class AndroidTabLayoutActivity extends TabActivity implements OnTabChangeListener {
TabHost tabHost;
TabWidget tabWidget;
Menu menu;
View v;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tabWidget = getTabWidget();
tabHost = getTabHost();
tabHost.setOnTabChangedListener(this);

// Tab for category

Intent categoryIntent = new Intent(this, CatagoryEvent.class);
categoryspec.setContent(categoryIntent);
// Adding all TabSpec to TabHost

}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
int tab = getTabHost().getCurrentTab();
if (tab==1)
inflater.inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.music:
// Single menu item is selected do something
// Ex: launching new activity/screen or show alert message
Intent music_intent = new Intent(getApplicationContext(),MusicFragment.class);
startActivity(music_intent);
return true;
case R.id.theatre:
Intent music_intent = new Intent(getApplicationContext(),TheatreFragment.class);
startActivity(music_intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
MusicFragment.java 在哪里
public class MusicFragment extends Fragment implements OnClickListener {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.music_layout, container, false);
LinearLayout mLayout = (LinearLayout) v
.findViewById(R.id.catagory_linearlayout);
mLayout.setBackgroundResource(R.drawable.music_full);
TableLayout tableLayout = (TableLayout) v.findViewById(R.id.maintable);
tableLayout.removeAllViews();
for (int i = 0; i < 50; i++) {
TableRow tableRow = new TableRow(v.getContext());
tableRow.setPadding(10, 10, 10, 10);
tableRow.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
TextView tv = new TextView(v.getContext());
tv.setTextColor(getResources().getColor(R.color.black_overlay));
tv.setText("random text here 11");
tableRow.addView(tv);
tv.setOnClickListener(this);
tableLayout.addView(tableRow, new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
return v;
}
public void onClick(View arg0) {
startActivity(new Intent(getActivity(), TextActivity.class));
}
}
我的 CatagoryEvent.java 是
public class CatagoryEvent extends FragmentActivity {
SectionsPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.catagory_layout);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
Fragment fragment;
switch (position) {
case 0:
fragment = new MusicFragment();
break;
case 1:
fragment = new TheatreFragment();
break;
default:
fragment = null;
break;
}
return fragment;
}
@Override
public int getCount() {
// Show 3 total pages.
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return getString("Music");
case 1:
return getString("Theatre");
}
return null;
}
}
}
问题
问题在于单击菜单项 MusicFragment.java 未调用并要求在 androidmanifaste 中声明但无法在 androidmanifaste 上声明
有没有办法从活动中调用片段类？
