the code works fine at the first time but when i rotate the screen to landscape it is disabling my fragment button even it is no longer usable after i change the orientation back to normal(portrait). why this is happening??
Main Activity
public class MainActivity extends AppCompatActivity {
Button button;
EditText editText;
TextView textView;
fragment_one fragment_one;
FragmentManager fragmentManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragment_one = new fragment_one();
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().add(R.id.container,fragment_one).commit();
button = (Button) findViewById(R.id.mybutton_main);
textView = (TextView) findViewById(R.id.mytextView_main);
editText = (EditText) findViewById(R.id.myedittext_main);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
textView.setText("button Clicked");
editText.setText("button Clicked");
}
});
}
}
Fragment
public class fragment_one extends Fragment implements View.OnClickListener {
Button button;
TextView textView;
public fragment_one() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_fragment_one, container, false);
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
button = (Button) getActivity().findViewById(R.id.mybutton_frag);
textView = (TextView) getActivity().findViewById(R.id.mytextView_frag);
button.setOnClickListener(this);
}
#Override
public void onClick(View v) {
textView.setText("clicked");
}
}
Try this:
if (savedInstanceState == null) {
fragment_one = new fragment_one();
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.add(R.id.container,fragment_one)
.commit();
}

data is sent to a tabbed acticity having 2 fragments and
the data is shown in textview of first fragment. Error is the data wont show in the textview while running

I tried but i am getting errors "Onclick listener can't be applied here" Please help me guys
Here is my Fragment.java
public class Fragment extends Fragment {
public Fragment() {
// 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_layout, container, false);
final Button button = (Button) rootView.findViewById(R.id.payment_info);
final Button button1 = (Button) rootView.findViewById(R.id.redeem);
final Button button2 = (Button) rootView.findViewById(R.id.make_payment);
final Button button3 = (Button) rootView.findViewById(R.id.payment_histories);
// Inflate the layout for this fragment
return rootView;
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
}
#Override
public void onDetach() {
super.onDetach();
}
}
OnClickListener is an interface, so you have not to only extend the fragment but to implement the OnClick.
Try this on your declaration of the class:
public class Fragment extends Fragment implements OnClickListener
Hope it helps.
I have a button which adds a textview to my fragment. When I close the activity the textview disappears. The only thing I like to know is how to save and retrieve the created textview.
public class trainingsplan extends Fragment {
ImageButton Btn;
LinearLayout Layout;
private ArrayList<View> mViews= new ArrayList<View>();
int i;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.trainingsplan, container, false);
setHasOptionsMenu(true);
Btn = (ImageButton) rootView.findViewById(R.id.imageButton3);
Layout = (LinearLayout) rootView.findViewById(R.id.linearLayout);
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
final TextView Test = new TextView(getActivity());
Test.setLayoutParams(lparams);
Test.setText("Hallo wie gehts dir ?");
Btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Layout.addView(Test);
mViews.add(Test);
}
});
return rootView;
}
viewPager4 Fragment Activities
If I click on the Texts that play short sounds, one after another then after sometimes the mediaplayer hangs and doesn't play any sound. But if I'm able to destroy activity and recreate the same activity with refresh button in Action Bar, I'd be able to click sounds again.
So what to write in the code for R.id.item2?
Or there is any other way that continuous clicking on short sounds by these texts is possible without any hang kind of problem?
Following is the reference code:
public class module1 extends FragmentActivity {
static Context con;
static int length = 0;
ViewPager mViewPager;
SectionsPagerAdapter mSectionsPagerAdapter;
static MediaPlayer mediaplayer, mediaplayert, m;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
con = this;
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.mains, menu);
// Just .main into .mains [created new for different behavior of Action Bar]
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.item1) {
Intent in = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://www.google.com"));
startActivity(in);
}
if (item.getItemId() == R.id.item2) {
//what should i write here? to destroy and recreate the same fragment activity again.
//Problem: After clicking fast on one after another text links, mediaplayert hangs and doesnt play
//Solution: exit app destroy and reopen, then mediaplayer works fine...
//SO, what to write here? kindly help!
}
return super.onOptionsItemSelected(item);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int arg0) {
Fragment ff = new DummySectionFragment1();
switch (arg0) {
case 0:
ff = new DummySectionFragment1();
break;
}
Bundle args = new Bundle();
args.putInt(DummySectionFragment1.ARG_SECTION_NUMBER, arg0 + 1);
ff.setArguments(args);
return ff;
}
#Override
public int getCount() {
return 1;
}
#Override
public CharSequence getPageTitle(int arg0) {
Locale l = Locale.getDefault();
switch (arg0) {
case 0:
return getString(R.string.title_section27).toUpperCase(l);
}
return null;
}
}
public static class DummySectionFragment1 extends Fragment {
public static final String ARG_SECTION_NUMBER = "section_number";
public DummySectionFragment1() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.m01set01, container, false);
// Genius Shot by Stupid vIC//
TextView Text = (TextView) rootView.findViewById(R.id.textView2);
Text.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
mediaplayert = MediaPlayer.create(MainActivity.con,
R.raw.sound1);
mediaplayert.start();
}
});
TextView Text1 = (TextView) rootView.findViewById(R.id.textView4);
Text1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
mediaplayert = MediaPlayer.create(MainActivity.con,
R.raw.sound2);
mediaplayert.start();
}
});
TextView Text2 = (TextView) rootView.findViewById(R.id.textView6);
Text2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
mediaplayert = MediaPlayer.create(MainActivity.con,
R.raw.sound3);
mediaplayert.start();
}
});
return rootView;
}
}
#Override
protected void onDestroy() {
if (mediaplayert != null) {
mediaplayert.stop();
mediaplayert= null;
}
super.onDestroy();
}
}
So I got 2 fragments and an activity. Those 2 fragments are communicating each other via an interface.
Problem is, I can't change the TextView in the second fragment from Activity wih some text from fragment1.
There is the same problem( How to change fragment's textView's text from activity ) but there is no real solution so i thought i should open this.
Fragment 1:
public class test_layout extends Fragment {
DearListener activityCommander;
TextView custom_question_bar, list_number;
String selectedCustomQuestion;
boolean buttonClicked;
Button yiyecekButton;
Context c;
public interface DearListener {
public void getMyText(String theQuestion);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
activityCommander = (DearListener) activity;
Log.i("MYLOG", "onAttach");
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString());
}
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.new_test_layout, container, false);
//custom_question_bar= (TextView) v.findViewById(R.id.custom_question_bar);
//list_number= (TextView) v.findViewById(R.id.list_number);
yiyecekButton = (Button) v.findViewById(R.id.yiyecekButton);
Log.i("MYLOG", "Button referenced");
yiyecekButton.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View v){
Log.i("MYLOG", "onCLickListener Called");
onClickYiyecek(v);
}
}
);
return v;
}
public void onClickYiyecek(View v){
Log.i("MYLOG", "OnClickYiyecek");
activityCommander.getMyText("En sevdiğim yiyecek ne?");
}
public void onClickQuestionReady(View v){
if( custom_question_bar == null)
{
Toast.makeText(c, "Boşluğu doldurmadınız", Toast.LENGTH_SHORT).show();
}
activityCommander.getMyText(custom_question_bar.getText().toString());
}
}
And the Activity:
public class NewTest extends Activity implements test_layout.DearListener {
FragmentManager manager;
test_layout test_layout_frag;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_holder);
manager=getFragmentManager();
test_layout_frag = new test_layout();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.the_frame_layout, test_layout_frag);
transaction.commit();
}
#Override
public void getMyText(String theQuestion) {
manager=getFragmentManager();
answer_layout answer_layout_frag = new answer_layout();
answer_layout answer_layout_obj = (answer_layout)getFragmentManager().findFragmentById(R.id.fragment2);
answer_layout_obj.changeText(theQuestion);
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.the_frame_layout, answer_layout_frag);
transaction.commit();
Log.i("MYLOG", "Transaction Called");
//transaction.addToBackStack(null);
}
}
And the second fragment:
public class answer_layout extends Fragment {
TextView yourSelectedQuestion;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.new_answer_layout, container, false);
yourSelectedQuestion= (TextView) v.findViewById(R.id.yourSelectedQuestion);
return v;
}
public void changeText(String a) {
Log.i("MYLOG", "changeText");
Log.i("MYLOG", a);
yourSelectedQuestion.setText(a);
}
}
No exception is given but the TextView in second fragment isn't changing.
Since i didn't write the xml here, I can if its needed. Using FrameLayout and it contains 2 fragments inside it.
In myFragment class write a static method:
public static myFragment newInstance(String txt) {
myFragment myfragment = new myFragment();
Bundle args = new Bundle();
args.putString("TEXT", txt);
myfragment.setArguments(args);
return myfragment;
}
after that in OnCreate method of myFragment class inflate the textView tv and
tv.setText(getArguments().getString("TEXT"));
In main FragmentActivity class do:
myFragment fragment = myFragment.newInstance(textToBeSent);
before replace,
fragmentTransaction.replace(R.id.fr_dynamic, fragment);
fragmentTransaction.commit();
