Hi,
I have an issue as the above image shown, on the left there is a button inside a webview. When I click on button a popupwindow in android should be appeared. In that popup window i need a webview.
now its all working fine without the webview in popup window.
this popup window is invoked by javascript interface
public class AppJavaScriptProxy {
private Activity activity = null;
public AppJavaScriptProxy() {
}
#JavascriptInterface
public String showMessage(String footNoteNo) {
Integer footNoteNoInt = Integer.parseInt(footNoteNo);
footnote = myDbHelper.getFootnote(chapterNumber, footNoteNoInt);
try {
LayoutInflater inflater = (LayoutInflater) HomeActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.footnote_popup,
(ViewGroup) findViewById(R.id.popup_footnote));
popup = new PopupWindow(layout, ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT, true);
popup.showAtLocation(layout, Gravity.CENTER, 0, 0);
txt_footnote=(TextView) layout.findViewById(R.id.text_footnote);
txt_footnote.setTypeface(malayalamfont);
popup_close = (ImageButton) layout.findViewById(R.id.btn_close_popup);
txt_footnote.setText(footnote);
final WebView footnoteWView = (WebView) layout.findViewById(R.id.footnotePopupWebview);
footnoteWView.getSettings().setJavaScriptEnabled(true);
footnoteWView.loadUrl("file:///android_asset/www/footNotePopup.html");
footnoteWView.clearCache(true);
footnoteWView.setWebViewClient(new WebViewClient(){
public void onPageFinished(WebView view, String url){ footnoteWView.loadUrl("javascript:getFootnote('" + footnote + "')");
}
});
popup_close.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
popup.dismiss();
}
});
}
catch (Exception e) {
e.printStackTrace();
};
}
}

I am new to android studio and Java. I have create custom dialog box with input textbox. I want to pass data from custom dialog to fragment layout. How can I achieve that ?
I saw this post but didn't get it. Please help me out !
Passing a data from Dialog to Fragment in android
Edited
Here's my code >>
public class IncomeFragment extends Fragment{
TextView title, textRsTotal;
Dialog dialog;
int total = 0;
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
title = view.findViewById(R.id.totalIncomeTitle);
Button button = view.findViewById(R.id.addIncomeBtn);
textRsTotal = view.findViewById(R.id.totalExpenseTitle);
dialog = new Dialog(getActivity());
if (getActivity() != null) {
if (!CheckInternet.isNetworkAvailable(getActivity())) {
//show no internet connection !
}
}
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
dialog.setContentView(R.layout.income_custom_dialog);
dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
RadioGroup radioGroup = dialog.findViewById(R.id.radioGroup);
Button buttonAdd = dialog.findViewById(R.id.addBtn);
TextInputEditText editText = dialog.findViewById(R.id.editText);
radioGroup.clearCheck();
radioGroup.animate();
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
RadioButton radioButton = (RadioButton) radioGroup.findViewById(checkedId);
}
});
buttonAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int selectedId = radioGroup.getCheckedRadioButtonId();
if (selectedId == -1) {
Toast.makeText(getActivity(), "Please select your income type", Toast.LENGTH_SHORT).show();
} else {
RadioButton radioButton = (RadioButton) radioGroup.findViewById(selectedId);
String getIncome = editText.getText().toString();
Toast.makeText(getActivity(), radioButton.getText() + " is selected & total is Rs."+ total, Toast.LENGTH_SHORT).show();
}
}
});
dialog.show();
}
});
super.onViewCreated(view, savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_income, container, false);
// Inflate the layout for this fragment
return view;
}
}
Ok, try this :
public class IncomeFragment extends Fragment {
TextView title, textRsTotal;
Dialog dialog;
int total = 0;
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
title = view.findViewById(R.id.totalIncomeTitle);
Button button = view.findViewById(R.id.addIncomeBtn);
textRsTotal = view.findViewById(R.id.totalExpenseTitle);
dialog = new Dialog(getActivity());
if (getActivity() != null) {
if (!CheckInternet.isNetworkAvailable(getActivity())) {
//show no internet connection !
}
}
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showDialog(new MyCallback() {
#Override
public void setText(String text) {
textRsTotal.setText(text);
}
});
}
});
super.onViewCreated(view, savedInstanceState);
}
private void showDialog(MyCallback myCallback) {
dialog.setContentView(R.layout.income_custom_dialog);
dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
RadioGroup radioGroup = dialog.findViewById(R.id.radioGroup);
Button buttonAdd = dialog.findViewById(R.id.addBtn);
TextInputEditText editText = dialog.findViewById(R.id.editText);
radioGroup.clearCheck();
radioGroup.animate();
radioGroup.setOnCheckedChangeListener((radioGroup1, checkedId) -> {
RadioButton radioButton = (RadioButton) radioGroup1.findViewById(checkedId);
});
buttonAdd.setOnClickListener(view1 -> {
int selectedId = radioGroup.getCheckedRadioButtonId();
if (selectedId == -1) {
Toast.makeText(getActivity(), "Please select your income type", Toast.LENGTH_SHORT).show();
} else {
RadioButton radioButton = (RadioButton) radioGroup.findViewById(selectedId);
String getIncome = editText.getText().toString();
myCallback.setText(getIncome);
Toast.makeText(getActivity(), radioButton.getText() + " is selected & total is Rs." + total, Toast.LENGTH_SHORT).show();
}
});
dialog.show();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_income, container, false);
return view;
}
public interface MyCallback {
void setText(String text);
}
}
There are more than one method to achieve that, the one mentioned in the url you provided is suggesting to use a simple callback to forward event and data back to the calling fragment. So the pieces you are needing are all there:
Write a callback interface: public interface Callback1{ public void onInteraction(String thingToCommunicateBack); }
In your fragment: and while building the instance of your dialog, pass an instance you've built of Callback1 to that dialog like this Callback1 mCallback = new Callback1() { public void onInteraction(String thingToCommunicateBack) { /*TODO receive data, handle and update layout*/ }; (the whole fragment could be that instance using the keyword this if you decide to implement the interface there instead, like this
class Fragment1 extends Fragment implements Callback1 and implement its method within fragment's class after the keyword override)
In your Dialog class: when the interaction (click) that should trigger the event and send data back happens, invoke callback's method like this: mCallback1.onInteraction("text from your EditText to pass")
Now, you passed some data from custom dialog back to a fragment.
I have Recycler ListView which I show in MainActivity and the first item it is as selected, I have done to click for another items but the last stays clicked and when I try to take this recycler view to show me in next Activity it doesn't work.
The first item it is selected but I have a click method which when click an image makes as selected but when I click a new image this works but the first item stays as selected so continues for others images. I want only a image to be selected.
I don't want to write twice the same code.
Is it good if I have a class only for this method which I can use everytime I want.
The id of recycler view list it is the same on both xml's.
If you have any suggestion for my question please let me know.
This is the adapter for the RecyclerView.
public class ListViewAdapter extends RecyclerView.Adapter<ListViewAdapter.ViewHolder>{
private int selectedItem;
private ArrayList<Integer> mImages = new ArrayList<>();
private ArrayList<String> mSearchUrl = new ArrayList<>();
private Context mContext;
public ListViewAdapter(ArrayList<Integer> images, ArrayList<String> SearchUrl, Context context) {
mImages = images;
mContext = context;
mSearchUrl = SearchUrl;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.s_engine_item, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder viewHolder, final int i) {
selectedItem = 0;
if (selectedItem == i) {
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
}
Glide.with(mContext).load(mImages.get(i))
.into(viewHolder.image);
viewHolder.searchUrl.setText(mSearchUrl.get(i));
viewHolder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.image.setBackgroundColor(Color.parseColor("#30000000"));
selectedItem = i;
}
});
}
#Override
public int getItemCount() {
return mImages.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView image;
TextView searchUrl;
public ViewHolder(#NonNull View itemView) {
super(itemView);
image = itemView.findViewById(R.id.ivEngine);
searchUrl = itemView.findViewById(R.id.ivEngineText);
}
}
}
This is the method in MainActivity.class
public void intSearch() {
mImages.add(R.drawable.s_bing);
mSearchUrl.add("https://www.bing.com/search?q=");
mImages.add(R.drawable.s_google);
mSearchUrl.add("https://www.google.com/search?q=");
mImages.add(R.drawable.s_yahoo);
mSearchUrl.add("www.yahoo.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
mImages.add(R.drawable.amazon_white256);
mSearchUrl.add("www.amazon.com");
initRecyclerView();
}
private void initRecyclerView() {
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
RecyclerView recyclerView = findViewById(R.id.lvEngines);
recyclerView.setLayoutManager(layoutManager);
ListViewAdapter adapter = new ListViewAdapter(mImages, mSearchUrl, this);
recyclerView.setAdapter(adapter);
}
This is the button which takes to another activity.
btnSearch.setOnClickListener(new View.OnClickListener() {

i have problem that i cannot call dialog method from another activity, the dialog get user input into sharedprefrnces
here my activity that i want check if theres stored sharedprefernce if not exist i want the dialog appear to get the user input and after i click ok its continue running the main activity
here the main
public class main extends Activity {
private Button button;
private EditText CardNumber;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
checkid();
}
});
}
public void checkid(){
File f = new File(
"/data/data/com.example.ahmed_samir.enjaz/shared_prefs/MyPrefs.xml");
if (f.exists())
Toast.makeText(OpreatorMobily.this, "exist:", Toast.LENGTH_LONG).show();
else {
NationalId na= new NationalId();
na.dialogmethod();
}
}
}
and here my second activity of dialog
public class NationalId extends Activity {
public static final String MyPREFERENCES = "MyPrefs";
public static final String Name = "nameKey";
SharedPreferences sharedpreferences;
final Context context = this;
private Button button;
private TextView result;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_national_id);
dialogmethod();
// components from main.xml
button = (Button) findViewById(R.id.button1);
result = (TextView) findViewById(R.id.tv1);
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
// add button listener
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
dialogmethod();
}
});
}
public void dialogmethod(){
LayoutInflater li = LayoutInflater.from(context);
View promptsView = li.inflate(R.layout.prompts, null);
android.app.AlertDialog.Builder alertDialogBuilder = new android.app.AlertDialog.Builder(
context);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialogUserInput);
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String n = userInput.getText().toString();
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(Name, n);
editor.commit();
// edit text
result.setText(userInput.getText());
Toast.makeText(NationalId.this, "saved:" + n, Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
android.app.AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
}
You should not do this. A possible solution is to create a separate class which contains a static method for your dialog.
So in your activity you can call it like this:
Dialog myDialog = CustomDialog.createDialog(this);
myDialog.show();
Inside the static method:
public static Dialog createDialog(Context context) {
Dialog dialog = new Dialog(this);
//do all the initialization stuff
//return the dialog
return dialog;
}
So i made a bunch of 4 buttons , put an intent to each of them . They all navigate to the same Fragment class . But their extras are different, so if button1 was clicked , Fragment would open and do a certain action , if button2 was clicked , Fragment would do another action and so on. I tried the code on normal activities and it worked , but in fragments its not working . It just returns me "Id is null"
Class sending the intent
public class Intennt extends ActionBarActivity {
Button bt1,bt2,bt3,bt4;
Context context = this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intennt);
bt1 = (Button) findViewById(R.id.button);
bt2 = (Button) findViewById(R.id.button2);
bt3 = (Button) findViewById(R.id.button3);
bt4 = (Button) findViewById(R.id.button4);
bt1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(context, ItemListActivity.class);
i.putExtra(ItemDetailFragment.ID_ACTION,ItemDetailFragment.ACTION_1);
startActivity(i);
}
});
bt2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(context, ItemListActivity.class);
i.putExtra(ItemDetailFragment.ID_ACTION,
ItemDetailFragment.ACTION_2);
startActivity(i);
}
});
}
Fragment receiving the intent and extras
public class ItemDetailFragment extends Fragment {
public static final int ACTION_1 = 1;
public static final int ACTION_2 = 2;
public static final int ACTION_3 = 3;
public static final int ACTION_4 = 4;
public static final int ACTION_NULL = -1;
public static final String ID_ACTION = "action_id";
public static final String ARG_ITEM_ID = "item_id";
private DummyContent.DummyItem mItem;
public ItemDetailFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments().containsKey(ARG_ITEM_ID)) {
// Load the dummy content specified by the fragment
// arguments. In a real-world scenario, use a Loader
// to load content from a content provider.
mItem =
DummyContent.ITEM_MAP.get(getArguments().getString(ARG_ITEM_ID));
}
int id = getActivity().getIntent().getIntExtra(ID_ACTION, -1);
if (id == ACTION_NULL) {
Log.d("TAG", "id is null");
Toast.makeText(getActivity(), "id is null!",
Toast.LENGTH_SHORT).show();
} else if (id == ACTION_1) {
Log.i("TAG", "ALLOHA! from button 1");
Toast.makeText(getActivity(), "Aloha from button 1!",
Toast.LENGTH_LONG).show();
} else if (id == ACTION_2) {
Log.i("TAG", "Hello from button 2");
Toast.makeText(getActivity(),"Hello from button 2!",
Toast.LENGTH_LONG).show();
}
else if (id == ACTION_3) {
Log.i("TAG", "Hello from button 3");
Toast.makeText(getActivity(),"Hello from button 2!",
Toast.LENGTH_LONG).show();
}
else if (id == ACTION_4) {
Log.i("TAG", "Hello from button 4");
Toast.makeText(getActivity(),"Hello from button 2!",
Toast.LENGTH_LONG).show();
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_item_detail,
container, false);
return rootView;
}
}
To navigate to a fragment, you need to instantiate the fragment class then use the FragmentManager to proceed to a transaction :
FragmentClass fragment = new FragmentClass();
getFragmentManager()
.beginTransaction()
.replace(R.id.your_fragment_view, fragment)
.commit();
You can proceed to every action right in the current activity (as it stays the main activity).
public class Questions extends DialogFragment {
private static Button Submit;
public int count = 0;
public interface DialogListener {
void onQuestionsFinish(ArrayList<xmlQuestion> l);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_questions, container, false);
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
//getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
Submit = (Button) rootView.findViewById(R.id.SubmitButton);
Submit.setOnClickListener(new View.OnClickListener(){
public void onClick(View arg0){
for(int i = 0; i<questionList.size(); i++)
{
questionList.get(i).setAnswer();
}
DialogListener activity = (DialogListener) getActivity();
activity.onQuestionsFinish(questionList);
Questions.this.dismiss();
}
});

You don't have to use intents to start fragments. My main benefit for using fragments is being able to reference the data in each one much easier. You can simply create a new instance of your fragment class, and assign it's public variables. Then start it like so...
Questions q = new Questions();
q.count = 0;
q.show(getSupportFragmentManager(), "Dialog Fragment");
i have this simple code in my java class but it not run. where is the error?
