Position of DialogFragment in Android
(8 answers)
Closed 9 years ago.
I'm trying to locate my dialog in a specific location on screen.
Here is my dialog implementation :
public class DayDialog extends android.support.v4.app.DialogFragment {
public static DayDialog newInstance() {
DayDialog f = new DayDialog();
f.setCancelable(true);
f.setStyle(STYLE_NO_TITLE, 0);
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.dialog_calendar_day, container);
WindowManager.LayoutParams params = getDialog().getWindow()
.getAttributes();
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;//b.getInt("x");
params.y = 0;//b.getInt("y");
getDialog().getWindow().setAttributes(params);
return layout;
}
here is how my dialog shown! how can I locate it (0,0) ? it's like there is a frame or something around it!

There is fact a frame around it, that is defined in styles.xml, more specific it's the this 9-patch. The way i see it you have two options:
Start playing around with negative top/left margin params until you align it exactly where you want it (watch out to use dpi values).
Apply the DialogFragment.STYLE_NO_FRAME like so:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_FRAME, 0);
}

I have tried to create a dialog that occupies the full screen width from the old AlertDialog builder to the new DialogFragment approach in the onCreateView() and onViewCreated() to get the displayed dialog to occupy the full width of the screen. I can certainly get the width and height values of the screen but regardless of how I try to force the dialog to use these values, they are ignored. The displayed dialog is always the same width regardless of orientation.
In my latest attempt I have an xml layout that I inflate. I need to use a custom view so I cannot define that view in xml. So I add it.
Here is the most current attempt I have in my DialogFragment code. Of course this is just one of many attempts I have made trying to follow hints from posts and Slidenerd videos.
public class PopupDialog extends DialogFragment implements View.OnClickListener
{
private static final String TAG = PopupDialog.class.getName();
Button cancel = null;
Button focus = null;
View viewInput = null;
int width;
int height;
int id;
public PopupDialog()
{
}
public PopupDialog(View v, int id, int width, int height)
{
viewInput = v;
this.id = id;
this.width = width;
this.height = height;
}
#Override
public View onCreateView(LayoutInflater inflator, ViewGroup container, Bundle savedInstance)
{
Log.d(TAG, "onCreateView of DialogFragment called.");
View viewDialog = inflator.inflate(R.layout.popup_dialog, null);
// RelativeLayout relativeLayout = (RelativeLayout)viewDialog;
// LayoutParams params = new LayoutParams(width, height);
// relativeLayout.setLayoutParams(params);
// Point point = new Point();
// Activity activity = getActivity();
// activity.getWindowManager().getDefaultDisplay().getSize(point);
// if(point.x > point.y)
if(width > height)
{
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
else
{
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
ViewParent parent = viewInput.getParent();
if(parent != null)
{
Log.d(TAG, "View already present. Removing.");
((ViewGroup)parent).removeView(viewInput);
}
LayoutParams params = new LayoutParams(width, height);
viewInput.setLayoutParams(params);
((ViewGroup)viewDialog).addView(viewInput, 0);
cancel = (Button)viewDialog.findViewById(R.id.btn_cancel);
focus = (Button)viewDialog.findViewById(R.id.btn_focus);
cancel.setOnClickListener(this);
focus.setOnClickListener(this);
setCancelable(false);
return viewDialog;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
Log.d(TAG, "onViewCreated of DialogFragment called.");
//getDialog().getWindow().setLayout(LayoutParams.MATCH_PARENT, height);
getDialog().getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
WindowManager.LayoutParams wmlp = getDialog().getWindow().getAttributes();
wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = 10; //x position
wmlp.y = 450 * (id) + 10;
// wmlp.width = width;
// wmlp.height = height;
}
I am plotting a sine wave. The view has the correct size as the sine wave has a range of 0 to 12 but in the landscape orientation the displayed dialog box only gets a little more than half way, so 0 to 6 + is seen and then one has to wait for the wave to recycle as it plots from 6 to 12 before it becomes visible again when it goes back to 0. I AM able to place the dialog box upper left hand corner.
Does anyone know how to solve this problem? I went to the fragment because I was led to believe that the canned AlertDialog approach was fixed in width and there was nothing one could do. I am facing the same limitation with the DialogFragment.
try adding this code in on create() method after setContentView
getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
I gave up and created my graph in a ListView in a ViewFlipper. Not want I wanted but I got more real estate for the graph.
I'm currently working on a small AR app for Android and am facing the problem of integrating Unity3d into an activity. The requirements indicate that I need to be able to present some Android UI - e.g. menus and an action bar - and a camera view that will display a model created in Unity3d when the target is detected.
I found a link that helped me a lot: Unity3d forums. One of the users there asked the same question I have now but never got any proper answer -that's why I'm posting here.
Problem:
I got a small Unity3d project that is essentially a white cube and am trying to display it in one of my Android activities. The model looks fine when activity doesn't have setContentView() in its onCreate() method but then I can't specify my layout in an XML file.
When I do add the setContentView() method, I can see the cube but it's very small and there doesn't seem to be any way of actually making it change its size.
The XML file:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/unityView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
1st version of the activity implementation:
public class HomeActivity extends UnityPlayerActivity {
UnityPlayer unityPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
And the resulting screenshot:
2nd version of the activity implementation:
public class HomeActivity extends UnityPlayerActivity {
UnityPlayer unityPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
unityPlayer = new UnityPlayer(this);
int glesMode = unityPlayer.getSettings().getInt("gles_mode", 1);
unityPlayer.init(glesMode, false);
FrameLayout layout = (FrameLayout) findViewById(R.id.unityView);
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
layout.addView(unityPlayer.getView(), 0, lp);
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
unityPlayer.windowFocusChanged(hasFocus);
}
}
And the resulting screenshot:
Could anyone explain to me why that is and how to fix it?
While I still don't know why it works like that, I've found a way of fixing it.
Instead of simply using setContentView() in onCreate(), extend onResume() and in that method recursively look through all the available views to find the parent view of the UnityPlayer object. Once that's found, layouts and other views can be inflated and added to that parent view.
Here's the link with a code example - I've used this to make my app work: https://developer.vuforia.com/resources/dev-guide/extending-unity-android-activity-and-adding-custom-views-eclipse
Edit: Here's a code snippet showing my solution.
#Override
public void onResume() {
super.onResume();
if (unityPlayer == null) {
View rootView = findViewById(android.R.id.content);
unityPlayer = findUnityPlayerView(rootView);
if (unityPlayer != null) {
ViewGroup unityPlayerParentView = (ViewGroup)(unityPlayer.getParent());
View mainHomeView = getLayoutInflater().inflate(R.layout.activity_main, null);
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
unityPlayerParentView.addView(mainHomeView, layoutParams);
}
}
}
and
private UnityPlayer findUnityPlayerView(View view) {
if (view instanceof UnityPlayer) {
return (UnityPlayer) view;
}
if (view instanceof ViewGroup) {
ViewGroup childrenViews = (ViewGroup) view;
for (int i = 0; i < childrenViews.getChildCount(); i++) {
UnityPlayer foundView = findUnityPlayerView(childrenViews.getChildAt(i));
if (foundView != null) {
return foundView;
}
}
}
return null;
}
Interesting one this.
So we have a "Details" view that is shown over a GoogleMap, and for Tablets this activity is forced to be styled like a dialog.
This details view has a GoogleMap within it.
This works fine within our Nexus 10, however the Galaxy Note 10 2 (4.0.1) is having some real issues with this approach.
Graphically the ActionBar title and Home Icon and being made transparent, and also the Map in the Details view is being dimmed somewhat.
Has anyone come across this type of issue before? I can't seem to find anything around this.
Thanks
Make activity into "dialog" code
#SuppressLint("InlinedApi")
private static void makeActivityIntoDialog(Activity activity) {
//To show activity as dialog and dim the background, you need to declare android:theme="#style/PopupTheme" on for the chosen activity on the manifest
//This will only be called for tablets over v11 so we are ok to ignore this warning
activity.requestWindowFeature(Window.FEATURE_ACTION_BAR);
activity.setFinishOnTouchOutside(true);
activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND,
WindowManager.LayoutParams.FLAG_DIM_BEHIND);
LayoutParams params = activity.getWindow().getAttributes();
DisplayMetrics dm = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
if (dm.heightPixels < dm.widthPixels){
params.height = (4 * dm.heightPixels)/ 5 ; //relative height
params.width = (4 * dm.widthPixels)/ 7 ; //relative width
}else{
params.height = (3 * dm.heightPixels)/ 5 ; //relative height
params.width = (5 * dm.widthPixels)/ 7 ; //relative width
}
params.alpha = 1.0f;
params.dimAmount = 0.5f;
activity.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
I have got it down to these lines of code which is causing the actionbar graphical error.
mMapFragment = new SupportMapFragment();
if (mMapFragment.isAdded()){
getFragmentManager().beginTransaction().attach(mMapFragment);
}else{
getFragmentManager().beginTransaction().add(R.id.google_map_fragment_container, mMapFragment).commit();
}
Basically the second i Add the GoogleMap Fragment to the view the action bar gets buggery.
The answer was to place the map within a transparent frame layout - not sure why but it now does not cut out that strange transparent square from the title bar.
static public class WorkaroundMapFragment extends SupportMapFragment {
public WorkaroundMapFragment() {
super();
}
#Override
public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstance) {
View layout = super.onCreateView(layoutInflater, viewGroup, savedInstance);
layout.requestFocus();
FrameLayout frameLayout = new FrameLayout(getActivity());
frameLayout.setBackgroundColor(getResources().getColor(android.R.color.transparent));
((ViewGroup) layout).addView(frameLayout,
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
return layout;
}
}
}
I am trying to create a custom DialogFragment, that extends over the whole width of my screen (or rather, parent fragment). Although I can make the borders of the DialogFragment transparent, there still is a padding on the right and left that I cannot get rid of.
This is my Fragment:
public static class LoaderDialog extends DialogFragment {
static LoaderDialog newInstance() {
LoaderDialog f = new LoaderDialog();
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.loader_f, container, false);
WindowManager.LayoutParams p = getDialog().getWindow().getAttributes();
p.y = getSupportActionBar().getHeight();
getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
getDialog().getWindow().setGravity(Gravity.TOP);
getDialog().getWindow().setAttributes(p);
return view;
}
}
This is a picture, how it looks like:
As you can see, the DialogFragment (the red thing) has some margins on the side. I want those to be gone. Any idea how to do this (in java, if possible)?
You can use:
WindowManager.LayoutParams wmlp = getDialog().getWindow().getAttributes();
wmlp.gravity = Gravity.FILL_HORIZONTAL;
Full example:
public class TextEditor extends DialogFragment {
public TextEditor () {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_text_editor, container);
WindowManager.LayoutParams wmlp = getDialog().getWindow().getAttributes();
wmlp.gravity = Gravity.FILL_HORIZONTAL;
return view;
}
}
try this:
p.horizontalMargin = 0;
use this style for DialogFragment
<item name="android:windowNoTitle">true</item>
<item name="android:padding">0dp</item>
or use this code 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);
ps. 220 is DialogFragment height, change it as u wish
Create a style element in your style.xml file. Copy the code below to 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>
Then in the createDialog method of your DialogFragment class,
dialog = new Dialog(getActivity(), R.style.CustomDialog);
This is working for me and hope this will help you too
Try to use LayoutParams.MATCH_PARENT instead. Fill_parent is drepecated. Moreover if you have set a padding for your view that is normal that is not fill its parent's view.
I have been trying many commands to setup the size of my DialogFragment. It only contains a color-picker, so I have removed the background and title of the dialog:
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
However I also want to position the dialog where I want and it is problematic. I use:
WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();
params.width = LayoutParams.WRAP_CONTENT;
params.height = LayoutParams.WRAP_CONTENT;
params.gravity = Gravity.LEFT;
getDialog().getWindow().setAttributes(params);
But one (big) obstacle remains: even though my dialog pane is invisible, it still has a certain size, and it limits the positions of my dialog. The LayoutParams.WRAP_CONTENT are here to limit the size of this pane to my color-picker, but for some reason it does not work.
Has anyone been able to do something similar?
i met a similar question that is you can't set the dialogFragment's width an height in code,after several try ,i found a solution;
here is steps to custom DialogFragment:
1.inflate custom view from xml on method
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().setCanceledOnTouchOutside(true);
View view = inflater.inflate(R.layout.XXX,
container, false);
//TODO:findViewById, etc
return view;
}
2.set your dialog's width an height in onResume(),remrember in onResume()/onStart(),seems didn't work in other method
public void onResume()
{
super.onResume();
Window window = getDialog().getWindow();
window.setLayout(width, height);
window.setGravity(Gravity.CENTER);
//TODO:
}
After some trial and error, I have found the solution.
here is the implementation of my DialogFragment class :
public class ColorDialogFragment extends SherlockDialogFragment {
public ColorDialogFragment() {
//You need to provide a default constructor
}
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_color_picker, container);
// R.layout.dialog_color_picker is the custom layout of my dialog
WindowManager.LayoutParams wmlp = getDialog().getWindow().getAttributes();
wmlp.gravity = Gravity.LEFT;
return view;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_FRAME, R.style.colorPickerStyle);
// this setStyle is VERY important.
// STYLE_NO_FRAME means that I will provide my own layout and style for the whole dialog
// so for example the size of the default dialog will not get in my way
// the style extends the default one. see bellow.
}
}
R.style.colorPickerStyle corresponds to :
<style name="colorPickerStyle" parent="Theme.Sherlock.Light.Dialog">
<item name="android:backgroundDimEnabled">false</item>
<item name="android:cacheColorHint">#android:color/transparent</item>
<item name="android:windowBackground">#android:color/transparent</item>
</style>
I simply extend a default Dialog style with my needs.
Finally, you can invoke this dialog with :
private void showDialog() {
ColorDialogFragment newFragment = new ColorDialogFragment();
newFragment.show(getSupportFragmentManager(), "colorPicker");
}
For my use case, I wanted the DialogFragment to match the size of a list of items. The fragment view is a RecyclerView in a layout called fragment_sound_picker. I added a wrapper RelativeLayout around the RecyclerView.
I had already set the individual list item view's height with R.attr.listItemPreferredHeight, in a layout called item_sound_choice.
The DialogFragment obtains a LayoutParams instance from the inflated View's RecyclerView, tweaks the LayoutParams height to a multiple of the list length, and applies the modified LayoutParams to the inflated parent View.
The result is that the DialogFragment perfectly wraps the short list of choices. It includes the window title and Cancel/OK buttons.
Here's the setup in the DialogFragment:
// SoundPicker.java
// extends DialogFragment
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(getActivity().getString(R.string.txt_sound_picker_dialog_title));
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
View view = layoutInflater.inflate(R.layout.fragment_sound_picker, null);
RecyclerView rv = (RecyclerView) view.findViewById(R.id.rv_sound_list);
rv.setLayoutManager(new LinearLayoutManager(getActivity()));
SoundPickerAdapter soundPickerAdapter = new SoundPickerAdapter(getActivity().getApplicationContext(), this, selectedSound);
List<SoundItem> items = getArguments().getParcelableArrayList(SOUND_ITEMS);
soundPickerAdapter.setSoundItems(items);
soundPickerAdapter.setRecyclerView(rv);
rv.setAdapter(soundPickerAdapter);
// Here's the LayoutParams setup
ViewGroup.LayoutParams layoutParams = rv.getLayoutParams();
layoutParams.width = RelativeLayout.LayoutParams.MATCH_PARENT;
layoutParams.height = getListItemHeight() * (items.size() + 1);
view.setLayoutParams(layoutParams);
builder.setView(view);
builder.setCancelable(true);
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
// ...
});
builder.setPositiveButton(R.string.txt_ok, new DialogInterface.OnClickListener() {
// ...
});
return builder.create();
}
#Override
public void onResume() {
Window window = getDialog().getWindow();
window.setLayout(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
super.onResume();
}
private int getListItemHeight() {
TypedValue typedValue = new TypedValue();
getActivity().getTheme().resolveAttribute(R.attr.listPreferredItemHeight, typedValue, true);
DisplayMetrics metrics = new android.util.DisplayMetrics(); getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
return (int) typedValue.getDimension(metrics);
}
Here is fragment_sound_picker:
<?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="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/rv_sound_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
use this code for resize of Dialog Fragment android
public void onResume() {
super.onResume();
Window window = getDialog().getWindow();
window.setLayout(250, 100);
window.setGravity(Gravity.RIGHT);
}
