Hello I am working on an android application where I am using DialogFragment to display the dialog but its width is very small. How I can make this width to fill_parent to it ?
public class AddNoteDialogFragment extends DialogFragment {
public AddNoteDialogFragment() {
// Empty constructor required for DialogFragment
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
getDialog().setTitle(getString(R.string.app_name));
View view = inflater.inflate(R.layout.fragment_add_note_dialog,
container);
return view;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
// request a window without the title
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
}
fragment_add_note_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >
<EditText
android:id="@+id/addNoteEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:hint="@string/clock_enter_add_note"
android:imeOptions="actionDone"
android:inputType="textCapSentences|textMultiLine"
android:lines="5" />
<Button
android:id="@+id/submit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="@drawable/login_button"
android:text="@string/submit_button"
android:textColor="@android:color/white" />
</LinearLayout>

This is the solution I figured out to handle this issue:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
@Override
public void onStart() {
super.onStart();
Dialog dialog = getDialog();
if (dialog != null) {
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
}
}
Edit:
You can use the code below in onCrateView method of Fragment before return the inflated view.
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

Have you tried using the answer of Elvis from How to make an alert dialog fill 90% of screen size?
It is the following:
dialog.getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
Update:
Above code should be added inside onStart() method of the DialogFragment.
LayoutParams.FILL_PARENT is deprecated use LayoutParams.MATCH_PARENT instead.

This is worked for me
Create your custom style :
<style name="DialogStyle" parent="Base.Theme.AppCompat.Dialog">
<item name="android:windowMinWidthMajor">97%</item>
<item name="android:windowMinWidthMinor">97%</item>
</style>
Use this style in your dialog
public class MessageDialog extends DialogFragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogStyle);
}
// your code
}
回答4:
For me, it worked when I replaced the LinearLayout parent of the layout inflated in onCreateView by RelativeLayout. No other code change required.
回答5:
<!-- A blank view to force the layout to be full-width -->
<View
android:layout_width="wrap_content"
android:layout_height="1dp"
android:layout_gravity="fill_horizontal" />
in the top of my dialog layout did the trick.
回答6:
public class FullWidthDialogFragment extends AppCompatDialogFragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, R.style.Theme_AppCompat_Light_Dialog_Alert);
}
}
and if you want much more flexibility can extend AppCompat_Dialog_Alert and custom attributes
回答7:
In my case I also used the following approach:
@Override
public void onStart() {
super.onStart();
getDialog().getWindow().setLayout(LayoutParams.MATCH_PARENT, (int) getResources().getDimension(R.dimen.dialog_height));
}
}
But there were still small gaps between left and right edges of the dialog and the screen edges on some Lollipop+ devices (e.g. Nexus 9).
It was not obvious but finally I figured out that to make it full width across all the devices and platforms window background should be specified inside styles.xml like the following:
<style name="Dialog.NoTitle" parent="Theme.AppCompat.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:padding">0dp</item>
<item name="android:windowBackground">@color/window_bg</item>
</style>
And of course this style needs to be used when we create the dialog like the following:
public static DialogFragment createNoTitleDlg() {
DialogFragment frag = new Some_Dialog_Frag();
frag.setStyle(DialogFragment.STYLE_NO_TITLE, R.style.Dialog_NoTitle);
return frag;
}
回答8:
I want clarify this. Both the ways are right, But with different DialogFragment.
Using android.app.DialogFragment
@Override
public void onStart()
{
super.onStart();
Dialog dialog = getDialog();
if (dialog != null)
{
int width = ViewGroup.LayoutParams.MATCH_PARENT;
int height = ViewGroup.LayoutParams.MATCH_PARENT;
dialog.getWindow().setLayout(width, height);
}
}
Using android.support.v4.app.DialogFragment
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
}

Another solution that work for me without side effects was:
In your class that extends DialogFragment:
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogStyle);
}
In your styles:
<style name="DialogStyle" parent="ThemeOverlay.AppCompat.Dialog.Alert"></style>
回答10:
Based on other solutions, I have created my own.
<style name="AppTheme.Dialog.Custom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowNoTitle">true</item>
<item name="android:windowMinWidthMajor">100%</item>
<item name="android:windowMinWidthMinor">100%</item>
</style>
abstract class BaseDialogFragment : DialogFragment() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.AppTheme_Dialog_Custom)
}
}
回答11:
Create a custom style in your style.xml file. Just copy paste this code into your style.xml file
<style name="CustomDialog" parent="@android:style/Theme.Holo.Light" >
<item name="android:windowBackground">@null</item>
<item name="android:windowIsFloating">true</item>
</style>
Then in the createDialog method of your DialogFragment, create the dialog object by the code
dialog = new Dialog(getActivity(), R.style.CustomDialog);
This is working for me and hope this will help you too
回答12:
use this in onCreateView method of DialogFragment
Display display = getActivity().getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, **220**, getResources().getDisplayMetrics());
getDialog().getWindow().setLayout(width,px);
220 is dialog fragment height, change it as u wish
回答13:
User AlertDialog.Builder inside your DialogFragment. Add it in onCreateDialog method like this. And in onCreateView do nothing.
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
View view = LayoutInflater.from(getContext()).inflate(R.layout.gf_confirm_order_timeout_dialog, null);
final Bundle args = getArguments();
String message = args.getString(GfConstant.EXTRA_DATA);
TextView txtMessage = (TextView) view.findViewById(R.id.txt_message);
txtMessage.setText(message);
view.findViewById(R.id.btn_confirm).setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
if (mListener != null)
{
mListener.onDialogConfirmOK();
}
}
});
builder.setView(view);
Dialog dialog = builder.create();
dialog.setCanceledOnTouchOutside(false);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
回答14:
in your layout root, set android:minWidth to a very large value e.g
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="9999999dp">
...
</LinearLayout>

This is how i solved when i faced this issue. Try this.
in your DialogFragment's onActivityCreated, Add this code according to your need....
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
myview=inflater.inflate(R.layout.fragment_insurance_detail, container, false);
intitviews();
return myview;
}
@Override
public void onActivityCreated(Bundle arg0) {
super.onActivityCreated(arg0);
getDialog().getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
getDialog().getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
getDialog().getWindow().setGravity(Gravity.CENTER);
}
