我有两个活动。一个是普通的活动，其中包含listview，另一个是选项卡布局，它有两个选项卡。一个是“描述”选项卡，另一个是“示例代码”选项卡。
我为每个创建了两个单独的片段，分别为“OneFragment”和“TwoFragment”。我所需要的就是当用户从我的正常活动中点击一个项目时，该项目将被存储在字符串中，并且该字符串应传递到选项卡布局中，并且应在OneFragment即“描述”选项卡中显示。
（例如）我的列表包含{"Android"，“Studio”}，如果用户单击Android，则应将此文本传递到描述选项卡，并使用TextView显示文本。请帮助我。这里我包括我的相应代码。 NormalActivity - >ListActi.java

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
lv = (ListView) findViewById(R.id.listView);
final List<String> ListElementsArrayList = new ArrayList<String>(Arrays.asList(listElements));
final ArrayAdapter<String> adapter = new ArrayAdapter<String>
(getApplicationContext(), android.R.layout.simple_list_item_1, ListElementsArrayList);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Toast.makeText(getApplicationContext(), listElements[position],Toast.LENGTH_LONG).show();
s = listElements[position];
if(position == 1){
s = listElements[position];
Bundle bundle = new Bundle();
bundle.putString("ClickedItem", listElements[position]);
OneFragment fragobj = new OneFragment();
TwoFragment fag = new TwoFragment();
fragobj.setArguments(bundle);
fag.setArguments(bundle);
Intent i = new Intent(getApplicationContext(),BothLay.class);
startActivity(i);
}
}
});
}
}
TabActivity - > BothLay
public class BothLay extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_both_lay);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new OneFragment(), "Description");
adapter.addFragment(new TwoFragment(), "Sample Code");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount(){
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
描述标签 ->OneFragment（我所需要的只是从普通活动将数据传递到此片段）
public class OneFragment extends Fragment{
String strtext = "Ajay";
public OneFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootview = inflater.inflate(R.layout.fragment_one, container, false);
TextView textView = (TextView) rootview.findViewById(R.id.t1);
//strtext = getIntent().getStringExtra("ClickedItem"); //this doesn't work
textView.setText(strtext);
return rootview;
}
}
示例代码选项卡 -> 两个片段
public class TwoFragment extends Fragment{
public TwoFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_two, container, false);
}
}
