I'm creating a dialog fragment with a layout that uses checkboxes. However, I'm never able to render them with the material design look in pre-lollipop devices. However, I'm able to get it done in a regular activity. What do I have to do when dealing with DialogFragments?
These are parts of my DialogFragment code:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, R.style.Theme_AppCompat_Dialog);
Window window = dialog.getWindow();
window.requestFeature(Window.FEATURE_NO_TITLE);
window.getAttributes().windowAnimations = R.style.Share_Multiplayer_Animation;
return dialog;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.share_multiplayer_scorecard, container, false);
ButterKnife.bind(this, view);
ViewGroup shareContainer = ButterKnife.findById(view, R.id.container);
List<MultiplayerRound> multiplayerRoundList = mRound.getMultiplayerRoundList();
for (int i = 0; i < multiplayerRoundList.size(); i++) {
MultiplayerRound mpRound = multiplayerRoundList.get(i);
View rowView = inflater.inflate(R.layout.multiplayer_share_row, shareContainer, false);
TextView nameTv = ButterKnife.findById(rowView, R.id.et_name);
nameTv.setText(mpRound.getName());
CheckBox checkBox = ButterKnife.findById(rowView, R.id.cb_send_scorecard);
final EditText emailET = ButterKnife.findById(rowView, R.id.et_email);
emailET.addTextChangedListener(new CheckboxControllerTextWatcher(checkBox));
emailET.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
emailET.setSelection(emailET.getText().length());
}
});
String email = getEmail(mpRound);
emailET.setText(email);
updateCheckboxState(email, checkBox);
shareContainer.addView(rowView);
mPlayerViews[i] = rowView;
rowView.setTag(mpRound);
}
return view;
}
This is my dialog layout
<?xml version="1.0" encoding="utf-8"?>

Thank you.
As of revision 23 of AppCompat, you can use AppCompatDialogFragment to create a material design DialogFragment that is compatible back to Android 2.1.

I want to reach and set android:id="#+id/custom_image" or android:id="#+id/custom_text" , i didn't reach these items from my fragment.
How can i reach these items from fragment ?
Thank you
My fragment
public class GeneralPreferenceFragmentN extends PreferenceFragment {
private Context mContext;

super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_main);

preference.setOnPreferenceChangeListener(
sBindPreferenceSummaryToValueListener);

Object value;
if (preference instanceof MultiSelectListPreference) {
value = prefs.getStringSet(preference.getKey(), new HashSet<String>
());
} else {
value = prefs.getString(preference.getKey(), "");
}

Try this:
in your onCreate() initialize the view:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_abschliessen_einsatz, container, false);
//#INFO: Create a global View v element if you want to use the view in other funtions (for example on slected and so on). Otherwise just use
this.v = v;
//#INFO: Otherwise just use th View elemnt to to find by ID
myCustomImage = (AppCompatImageView) v.findViewById(R.id.custom_image);
myCustomText = (AppCompatTextView) v.findViewById(R.id.custom_text);
//Set Text or do stuff with the elements afterwards
return v;
}
//Use the view in other fuctions, ex. onSelcted
#Override
public void onSelected() {
//update UI when selected
//#INFO: Use the global View elemnt to to find by ID
myCustomImage = (AppCompatImageView) v.findViewById(R.id.custom_image);
myCustomText = (AppCompatTextView) v.findViewById(R.id.custom_text);
//Set Text or do stuff with the elements afterwards
}
I want to show a DialogFragment with no title, buttons, etc.(i.e, none of what is included in a typical Dialog) but just a ProgressBar spinner on a plain background. For a rough idea, the background's width matches that of the parent and spinner lies at the center of it. For this, I have a custom layout as follows:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
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">
<View
android:id="#+id/search_progress_alpha_indicator"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginBottom="8dp"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:layout_marginRight="16dp"
android:layout_marginEnd="16dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toTopOf="#+id/guideline3"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="#+id/guideline2"
android:background="#00ffffff"/>
<ProgressBar
android:id="#+id/search_tutors_progress_bar"
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:visibility="gone"/>
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/guideline2"
app:layout_constraintGuide_percent="0.20"
android:orientation="horizontal"
tools:layout_editor_absoluteY="126dp"
tools:layout_editor_absoluteX="0dp" />
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/guideline3"
app:layout_constraintGuide_percent="0.80"
android:orientation="horizontal"
tools:layout_editor_absoluteY="378dp"
tools:layout_editor_absoluteX="0dp" />
</android.support.constraint.ConstraintLayout>
Here, View is the background on top of which the ProgressBar is supposed to spin.
But when I inflate this layout in the DialogFragment, it shows something completely different:
Here is the DialogFragment code:
public static class SearchIndicatorDialogFragment extends DialogFragment{
public static String FRAGMENT_TAG = "searchIndDiaFragTag";
private View alphaSearchIndicator;
private ProgressBar progressBar;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View dialogRootView = inflater.inflate(R.layout.fragment_search_dialog, container, false);
// Obtain the ProgressBar
progressBar = (ProgressBar) dialogRootView.findViewById(R.id.search_tutors_progress_bar);
// Obtain the Alpha search indicator
alphaSearchIndicator = dialogRootView.findViewById(R.id.search_progress_alpha_indicator);
return dialogRootView;
}
#Override
public void onStop() {
progressBar.setVisibility(View.GONE);
alphaSearchIndicator.setBackgroundColor(0x00ffffff);
super.onStop();
}
#Override
public void onResume() {
progressBar.setVisibility(View.VISIBLE);
alphaSearchIndicator.setBackgroundColor(0xA6ffffff);
super.onResume();
}
}
Why is it not showing my custom layout as intended?
EDIT: As an additional note, The problem in my case is that the background View is supposed to be occupying 60% area of screen(height wise) and for this I have constrained it in between the Guidelines. This is something, I am unable to achieve with other answers to similar questions regarding DialogFragment. Moreover, I would like to know, why does a DialogFragment doesn't display the correct by default in general?
If you change ConstraintLayout to Relative or Linear
This problem will be solved.
I was facing the same problem and I put my ConstraintLayout inside RelativeLayout and it worked.
I tried the same with LinearLayout but it didn't work.
Try this:
AlertDialog builder = new AlertDialog.Builder(this).create();
builder.setView(progressbar_id);
Window window = builder.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
builder.show();
Put ConstraintLayout inside RelativeLayout. The issue will be solved.
try this
Window window = yourDialog.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);
or
int width = getResources().getDimensionPixelSize(R.dimen.popup_width);
int height = getResources().getDimensionPixelSize(R.dimen.popup_height);
getDialog().getWindow().setLayout(width, height);
Try changing
View dialogRootView = inflater.inflate(R.layout.fragment_search_dialog, container, false);
to
View dialogRootView = inflater.inflate(R.layout.fragment_search_dialog, container, true);
I suppose we are the ones responsible for attaching our layout file’s View to its root ViewGroup.
I have a problem when declaring a button.
I will try to explain as specific as possible.
In my main Layout I have a Fragment containing a secondary Layout. In which I have several buttons.
My intention is that my main fichero.java to declare the buttons within the fragment.
Here we put the main 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:baselineAligned="false">
<fragment
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:name="josejuansosarodriguez.radioecca.conocecanarias.TrueoFalseFragment"
android:id="#+id/fragmentTrueFalse"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Grp1"
android:id="#+id/textGrp1"
android:textSize="25sp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"/>
<fragment
android:layout_width="fill_parent"
android:layout_height="450dp"
android:name="josejuansosarodriguez.radioecca.conocecanarias.Grp1FragmentP1"
android:id="#+id/fragmetaskGRP1"
android:layout_below="#+id/textGrp1"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp" />
</RelativeLayout>
Here we put the secondary Layout that has the buttons:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:id="#+id/fragment_TrueorFalse">
<Button
android:layout_width="120sp"
android:layout_height="wrap_content"
android:textAllCaps="false"
android:text="#string/buttontrue"
android:id="#+id/buttontrue"
android:layout_marginLeft="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" />
<Button
android:layout_width="120sp"
android:layout_height="wrap_content"
android:textAllCaps="false"
android:text="#string/buttonfalse"
android:id="#+id/buttonfalse"
android:layout_marginRight="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
And here I leave the my main activity:
public class Grp1Fragment extends Fragment {
private Button buttonTrue;
private Button buttonFalse;
private Button buttonNextAsk;
private View view;
public Grp1Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
buttonTrue = (Button) view.findViewById(R.id.buttontrue);
buttonTrue.setOnClickListener(this);
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_grp1, container, false);
return view;
}
My problem I find in the following line:
buttonTrue.setOnClickListener (this);
The message reads: View can not be in Applied to josejuansosarodriguez.radioecca.conocecanarias.Grp1Fragment
I hope I have spread far.
Thank you very much for everything, this forum is amazing.
Try this:
Note that you have to FIRST inflate the layout to make accesible the widgets of the layout.
Then you can "bind" the widgets, and finallly in this case, set the listeners to the buttons.
I set you a Log, if you need change it to Toast, or code
public class Grp1Fragment extends Fragment {
private Button buttonTrue;
private Button buttonFalse;
private Button buttonNextAsk;
private View view;
public Grp1Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_grp1, container, false);
//Declare your widgets (Buttons)
buttonTrue = (Button) view.findViewById(R.id.buttontrue);
buttonFalse = (Button) view.findViewById(R.id.buttonfalse);
//Set the Listeners
buttonTrue.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Toast or Log, or whateber you need
Log.d("Fragment1" , "Button: True");
}
});
buttonFalse.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Toast or Log, or whateber you need
Log.d("Fragment1" , "Button: FAlse");
}
});
//return the view
return view;
}
void setOnClickListener(View.OnClickListener l)
requires a OnClickListener, which Grp1Fragment is not.
Use something like
buttonTrue.setOnClickListener(new View.OnClickListener() {
void onClick(View v) {
... // reaction on the button
}
});
Here's how I called my DialogFragment:
DialogSelectAccount myDiag=new DialogSelectAccount();
myDiag.show(ft,"Diag" );
Here's how (partially) my DialogFragment is created:
public class DialogSelectAccount extends DialogFragment {
public DialogSelectAccount() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.dialog_select_account, container, false);
tvMessage = (TextView) rootView.findViewById(R.id.tvMessage);
btnAccountPublic = (Button) rootView.findViewById(R.id.btnAccountPublic);
btnAccountEnterprise = (Button) rootView.findViewById(R.id.btnAccountEnterprise);
tvMessage.setText(message);
btnAccountPublic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Login.setAccountType = 2;
dismiss();
}
});
btnAccountEnterprise.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Login.setAccountType = 1;
dismiss();
}
});
return rootView;
}
and here's the xml for my DialogSelectAccount
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_marginLeft="5dp"

android:textColor="#ffffffff"
android:background = "#drawable/roundedbutton" />
</LinearLayout>
</LinearLayout>
the problem is there's always an innoying white background displayed, as shown below. How do I remove it?
In the onCreateView() of your DialogFragment, replace
View rootView = inflater.inflate(R.layout.dialog_select_account, container, false);
with
View rootView = inflater.inflate(R.layout.dialog_select_account, container);
Also, add this to onViewCreated():
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
setStyle(DialogFragment.STYLE_NO_FRAME, android.R.style.Theme);
and in the outermost LinearLayout of the XML, change
android:layout_width="fill_parent"
android:layout_height="fill_parent"
to
android:layout_height="wrap_content"
android:layout_width="wrap_content"
Try this. This should work.
I suggest you create an alert dialog with your custom UI in onCreateDialog in your DialogFragment instead. Then you can then also easily add a style to it that will remove the white background.
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val view = activity!!.layoutInflater.inflate(R.layout.dialogfragment_my_custom_view, null)
val builder = AlertDialog.Builder(activity!!, R.style.MyDialogTheme)
return builder
.setView(view)
.create()
}
Then you can just create the "MyDialogTheme" like this:
<style name="ProgressDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowBackground">#color/automile_transparent</item>
</style>
You can create style for your dialog:
<style name="DialogStyle" parent="Base.Theme.AppCompat.Dialog">
<item name="android:windowNoTitle">true</item>
</style>
And use it in code by method:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new Dialog(getActivity(), R.style.DialogStyle);
}
Or you can set FEATURE_NO_TITLE for your dialog only in your code as is shown in the code below:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
Higher android version devices automatically remove title space. But for lower version we have to add some line of code.
It is more effective to add Window.FEATURE_NO_TITLE in onCreateDialog() method. Same as below :
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
// request a dialog window without the title
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
Here I think you are trying to hide the title bar. Use this
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
I'm writing some code for Android, the matter is that, when I call findViewById it returns me null, and I cannot understand why! I've been wasting my brain since yesterday, but I cannot figure out the solution. The goal is to set a layout as a header for a listView. Here is my code, respectively my header and my page:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/header"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp">
<TextView
android:text="#string/bydistance"
android:layout_gravity="left"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:textSize="13dp"
android:gravity="center_horizontal"/>
<TextView
android:text="#string/byactivity"
android:layout_gravity="right"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:textSize="13dp"
android:gravity="center_horizontal"/>
</LinearLayout>
<?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"
android:background="#ff0000"
>
<ListView
android:id="#+id/parkList"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="5.0dp">
</ListView>
</LinearLayout>
And here my code where I call the addheaderView:
public class NearMeFragment extends Fragment implements View.OnClickListener{
private FragmentManager fragmentManager;
#Override
public void onCreate(Bundle savedBundle){
super.onCreate(savedBundle);
}
#Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedBundle) {
View v = inflater.inflate(R.layout.park_list, container, false);
//TODO remove
make_test(v, container);
return v;
}
public void openTest(View view){
new LiveComment().show(getChildFragmentManager(), "dialog");
}
public void onClick(View view){
if (fragmentManager == null)
fragmentManager = getChildFragmentManager();
//if (view.getId() == R.id.test){
fragmentManager.beginTransaction().add(new LiveComment(), "livecomment").commit();
}
private void make_test(View v, ViewGroup container) {
ListView listView = (ListView) v.findViewById(R.id.parkList);
Park[] list = new Park[3];
list[0] = new Park("parco a", "acquasparta", false, false, 1, 2, 3);
list[1]=new Park("parco b", "perugia", false, false, 1, 2, 3);
list[2]=new Park("parco b", "perugia", false, false, 1, 2, 3);
ParkListAdapter adapter = new ParkListAdapter(v.getContext(), R.layout.small_park_container,list);
LinearLayout header = (LinearLayout) container.findViewById(R.id.header);
listView.addHeaderView(header);
listView.setAdapter(adapter);
}
}
The error is given at
listView.addHeaderView(header)
R.id.header is inside v not inside container.
Change
LinearLayout header = (LinearLayout) container.findViewById(R.id.header);
with
LinearLayout header = (LinearLayout) v.findViewById(R.id.header);
about the ViewGroup container to doc says:
If non-null, this is the parent view that the fragment's UI should be
attached to. The fragment should not add the view itself, but this can
be used to generate the LayoutParams of the view.
Edit: Since your header view is in another Layout you have to inflate it too:
#Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedBundle) {
View v = inflater.inflate(R.layout.park_list, container, false);
View header = inflater.inflate(R.layout.headerlayout, null);
//TODO remove
make_test(v, header);
return v;
}
and
private void make_test(View v, View header) {
// your code
// you have to remove LinearLayout header = (LinearLayout) container.findViewById(R.id.header);
listView.addHeaderView(header);
listView.setAdapter(adapter);
}
