So I am still fairly new to working with Android Studio and everything in it. I have been stuck on trying to get fragments to communicate directly with each other. Here I'm simply just trying to set the TextView text element within one of my fragments. I have looked for hours and tried a lot, but I'm not sure what to do. Also, I am implementing my fragments through code in a FrameLayout.
Here is my fragment whose text value I'm trying to edit:
public class ReceivingFrag extends Fragment {
TextView sender;
public void updateText(String text) {
sender.setText(text);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.frag_sender, container, false);
sender = (TextView) v.findViewById(R.id.sender);
return v;
}
}
I believe my root problem is that getView() and sender both return Null. I also understand that fragments are not technically views, but rather aid in the layout of views and ViewGroups. Any help is appreciated.
Not sure if it helps, but this is the method that calls the updateText() method within the ReceivingFrag class.
public void sendText(String text){
ReceivingFrag frag = new ReceivingFrag();
getSupportFragmentManager().beginTransaction().add(R.id.receiving_container, frag).commit();
getSupportFragmentManager().executePendingTransactions()
frag.updateText(text);
}
**Edit:
This is my MainActivity class that is calling and creating the Fragment:
public class MainActivity extends AppCompatActivity implements SendingFragment.TextClicked {
private static final String TAG = MainActivity.class.getSimpleName();
public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] myStringArray = {"Hello", "Nice To See You", "Bye"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, myStringArray);
ListView listView = (ListView) findViewById(R.id.mobile_list);
listView.setAdapter(adapter);
sendText("Hello");
}
#Override
public void sendText(String text){
ReceivingFrag frag = new ReceivingFrag();
getSupportFragmentManager().beginTransaction().add(R.id.receiving_container, frag).commit();
getSupportFragmentManager().executePendingTransactions();
frag.updateText(text);
}}
**Edit 2:
This is the MainActivity layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/apk/tools"
xmlns:tools2="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1">
<EditText android:id="#+id/edit_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/edit_message"
android:layout_weight="1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="sendMessage"
android:text="#string/button_send"/>
</LinearLayout>
<ListView android:id="#+id/mobile_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/receiving_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></FrameLayout></LinearLayout>
And this is the layout for the Fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/sender"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/frag_sender"
android:background="#color/gray"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"/></LinearLayout>
Solution:
So as mentioned below, the runtime error was fixed by adding
#Override
protected void onResume() {
super.onResume();
sendText("hello");
}
to the MainActivity class. After reading from https://developer.android.com/guide/components/fragments.html#Lifecycle
I think the statement
"Once the activity reaches the resumed state, you can freely add and remove fragments to the activity. Thus, only while the activity is in the resumed state can the lifecycle of a fragment change independently."
best explains the situation and why the error initially occurred.
If you instead put the sendText() in your onResume() like this,
#Override
protected void onResume() {
super.onResume();
sendText("Hello");
}
It will not give you the Null Pointer Exception. The fragment is still null when you call on it from onCreate().
Change your Fragment to this:
public class ReceivingFrag extends Fragment {
private TextView sender;
public void updateText(String text) {
sender.setText(text);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.frag_sender, container, false);
sender = (TextView) v.findViewById(R.id.sender);
return v;
}
}
and in your activity, before calling the updateText method, make sure the fragment transaction has executed by doing:
public void sendText(String text){
ReceivingFrag frag = new ReceivingFrag();
getSupportFragmentManager().beginTransaction().add(R.id.receiving_container, frag).commit();
getSupportFragmentManager().executePendingTransactions();
frag.updateText(text);
}

Code is too large to be posted here. Thats why i have only posted the code where i am finding an issue.
I am able to get newDesigns BUTTON instance.What is shocking for me is if try to play with button instance (VISIBLE/GONE) it gives me above mentioned exception.
Help is appreciated.
You shouldn't play with a view of the Fragment while you are in a Activity directly. You will not know what the view's state will be and this can potentially lead to issues you can't even think of(beleive me i faced many). To interact with the activity's views, make an interface:
public interface AccessFragmentViews{
public void setVisibilityForButton(boolean bool);
//any other methods that you need
}
Now implement this inside the fragment class and override the method.
class YourFragment implements AccessFragmentViews{
.
.
public void serVisibilityForButton(boolean shouldHide){
if(shouldHide){
yourButton.setVisibility(View.GONE);
}else{
yourButton.setVisibility(View.VISIBLE);
}
}
}
Now you can interact safely with the views of the fragment within a activity using this interface. Make sure that the fragment is alive before doing so though ;) accessing child's view are prone to WindowLeakedExceptions and illegalstateexceptions
In the activity use it as follows:
you can get the fragment reference by either finding it by its tag or by using the reference you used to create the fragment
//NOTE: it is very very dangerous to do the accessing on a fragment views from an activity
//first the alive check then the logic
if(yourFragmentReference!=null){
((AccessFragmentViews)yourFragmentReference).setVisibilityForButton(true);// or false if you want to make it visible
}
Add a method in your fragment class
public void changeButtonVisibility(boolean visibility){
if(visibility){
newDesigns.setVisibility(View.VISIBLE);
}else{
newDesigns.setVisibilty(View.GONE);
}
}
and in your activity class
add this line
public class HomeActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
CategoryFragment frag=(CategoryFragment) activity.getSupportFragmentManager()
.findFragmentByTag("cat_frag");
frag.changeButtonVisibility(true);
}
}
I called setRetainInstance(true) for a fragment. I added an EditText and TextView on the fragment. When rotated, the text in the EditText survived, but the text in the TextView was gone.
I think I can manually restore the text of the TextView, but I wonder why the system automatically restores the text for EditText, and not for TextView. Did I do something wrong?
Steps to reproduce.
Type "android" in the EditText
Press the [Test 1] button. The TextView now displays "android"
Rotate the device.
Result
The EditText has "android", but the TextView is empty.
MyFragment.java
public class MyFragment extends Fragment
{
private static final String TAG = "MyFragment";
EditText etInput;
Button btnTest1;
TextView tvMessage;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState)
{
Log.d(TAG, "onCreateView()");
View v= inflater.inflate(R.layout.my_fragment, container, false);
etInput = (EditText)v.findViewById(R.id.etInput);
btnTest1 = (Button)v.findViewById(R.id.btnTest1);
btnTest1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
tvMessage.setText(etInput.getText().toString());
Log.d(TAG, "btnTest1 was clicked");
}
});
tvMessage = (TextView) v.findViewById(R.id.tvMessage);
return v;
}
}
MainActivity.java
public class MainActivity extends AppCompatActivity
{
String TAG = this.getClass().getName();
#Override
protected void onCreate(Bundle savedInstanceState)
{
Log.d(TAG, "onCreate()");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
Fragment mf = fm.findFragmentById(R.id.placeholder);
if(mf == null)
{
Log.d(TAG, "creating new my fragment");
mf = new MyFragment();
mf.setRetainInstance(true);
fm.beginTransaction().add(R.id.placeholder, mf).commit();
}
}
}

If you want to enable auto restoration of TextView, you need to set freezesText attribute to true in your xml (or call setFreezesText(true)).
For TextView, freezesText default value is false, but in case of EditText, default value is true.
From documentation of freezesText:
If set, the text view will include its current complete text inside of
its frozen icicle in addition to meta-data such as the current cursor
position. By default this is disabled; it can be useful when the
contents of a text view is not stored in a persistent place such as a
content provider. For EditText it is always enabled, regardless of the
value of the attribute.
I have a fragment with his class:
public class FormatShortFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.bag_format_short, container, false);
return rootView;
}
}
And this is his layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</LinearLayout>
</RelativeLayout>
This fragment is shown by a FragmentPageAdapter.
The layout will grow when an user add an item from server (the origin of the item doesn't matter), and this item will be an horizontal linearlayout, with textview and edittext (item_name, item_value). This value can be modifiable, so must be an edittext, also, this edittext will receive values periodically from server, so can be updated automatically.
After explain this, how can I add this linearLayouts and his subviews to the GUI dynamically? and when should I update the interface?
Thanks a lot, any help is good received, I'm really lost on this on this themes.
EDITED WITH MODIFICATIONS:
I have modified the code in this way:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.bag_format_short, container, false);
return rootView;
}
#Override
public void onResume() {
super.onResume();
LinearLayout parentLinear = (LinearLayout) getActivity().findViewById(R.id.short_container);
for (int i = 1; i<10; i++ ){
LinearLayout innerLinear = (LinearLayout) new LinearLayout(getActivity());
TextView itemName = new TextView(getActivity());
itemName.setText("Nombre");
EditText itemValue = new EditText(getActivity());
itemValue.setText("Valor");
innerLinear.addView(itemName);
innerLinear.addView(itemValue);
parentLinear.addView(innerLinear);
}
}
#Override
public void onStart() {
super.onStart();
}
#Override
public void onStop() {
super.onStop();
}
And the fragment layout has been modified on this way:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<LinearLayout
android:id="#+id/short_container"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</LinearLayout>
</RelativeLayout>
Now the layout is growing in each for iteration.
In this point i have another problems, I hope you can help me with this.
- How can I generate a LayouParams object with attributes like gravity or weigth?
- How can I pass data from MainActivity to the Fragment?
- And how can i force the Fragment view to be raloaded with new data?
Also i need to know how bind a clickListener event to programatically linearLayouts added, i need modify some values on server depending on the name and the edited value.
Thanks a lot for this, you are saving my life.
you Can easily Update UI of Fragment on Button click or any event just
Like in Activity. You can get any view by
getActivity().findViewById()
See Example, It will help you to undersatand:-
public class FragmentTab3 extends SherlockFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab3, container, false);
return rootView;
}
#Override
public void onResume() {
super.onResume();
}
#Override
public void onStart() {
super.onStart();
LinearLayout linear = (LinearLayout) getActivity().findViewById(R.id.linear);
Button button = new Button(getActivity());
button.setText("Click Me");
linear.addView(button);
}
#Override
public void onStop() {
super.onStop();
}
}
If you want to add subview to a layout dynamically, take a look at RecyclerView in android documentation. Sounds like what you're looking for.
I am having an activity which has a list view which uses a list adapter to display elements. When the element which has text is clicked on the fragment should be created which has the play button, seek bar and has a media player. However I get this error when my activity is called.

First, you have given fill_parent for both width and height of your ListView which makes your ListView occupy the whole parent(here LinearLayout), so no place for Fragment. Its good that you have null check in your code if (frag == null), but again you are trying to add your fragment to the same View which is not in the screen(not attached).
Perhaps you would want to start a new activity if you found that your Fragment is not attached to your view hierarchy.
if (frag == null) {
Intent playerActivity = new Intent(DisplaysongDetails.this, PlayerActivity.class)
startActivity(playerActivity);
}
Now, create a new Activity called PlayerActivity and add PlayerFragment in its layout. You can pass any item data using Extras.
Another issue:
seekBar = (SeekBar)getActivity().findViewById(R.id.seekBar);
seekBar.setOnTouchListener(this);
seekBar is only defined as part of the Fragment layout, not the Activity's. That call to getActivity().findViewById() should return null and result in an NPE when trying to add the Listener. However, more info (from the stack trace) is needed to see if anything else is wrong (besides this and the String comparison).
What would be valid:
seekBar = (SeekBar)view.findViewById(R.id.seekBar);
seekBar.setOnTouchListener(this);
I have this app, that I created a custom dialog for. I must of goofed something up cause while the .show call on the dialog does indeed bring it up, it looks like a whole new fragment and it is not floating but instead replacing the ui with its contents. I did see in their help for DialogFragment:
http://hi-android.info/docs/reference/android/app/DialogFragment.html#Lifecycle
that one can embed a dialog as a regular fragment or not. Though I am not doing anything to do this so I cannot figure out why its acting like an embedded fragment and not floating. After thinking on it, is it the way I defined my XML definition? The dialogfragment example above didn't really give a definition for the xml layout, so maybe that is where my issue is? (Even added the gravity to the xml file, still no dice)
My xml definition for this Dialog is here:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:gravity="center_horizontal"

android:layout_width = "450sp"

<!-- fill out the data on the package total cost etc -->

Like I said displays just fine, the code for the fragment:
package com.viciousbytes.studiotab.subactivities.dialogfragments;
import ... ...
public class LocationPicker extends DialogFragment {
ArrayList<Location> mLocations;
public static LocationPicker newInstance()
{
LocationPicker loc = new LocationPicker();
return loc;
}
private void setLocations(ArrayList<Location> loc)
{
mLocations=loc;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Pick a style based on the num.
int style = DialogFragment.STYLE_NORMAL, theme = android.R.style.Theme;
setStyle(style, theme);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.location_dialog, container, false);
Spinner spinner = (Spinner)v.findViewById(R.id.location_spinner);
ArrayAdapter<Location> adapter = new ArrayAdapter<Location>(v.getContext(), android.R.layout.simple_spinner_item, mLocations);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
if(mLocations==null)
spinner.setPrompt("No Locations");
else
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new LocationSelectedListener());
// Watch for button clicks.
Button newBtn = (Button)v.findViewById(R.id.location_dlg_new);
newBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
// Cancel do nothing dismissthis
Button cancelBtn = (Button)v.findViewById(R.id.location_dlg_cancel);
cancelBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
// okay button means set listener with the selected location.
Button okBtn = (Button)v.findViewById(R.id.location_dlg_ok);
okBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// When button is clicked, call up to owning activity.
//create new start that activity...
}
});
return v;
}
}
It is called from a fragment itself? though does that matter? because I am calling a TimePIckerDialog and a DatePickerDialog and those work fine, but my calling code from my other fragment is:
void showLocationDialog() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment prev = getFragmentManager().findFragmentByTag("locpicker");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);
// Create and show the dialog.
DialogFragment newFragment = LocationPicker.newInstance();
newFragment.show(ft, "locpicker");
}
Your constructors are wrong. Try to have just one static method newInstance to instantiate the fragment for all cases and use a Bundle to store the arguments that you want to use in the fragment. Refer to Basic Dialog section here and extend it to your case.
