I tried to make my dialog fill in the whole screen. Here's the code:
public void onStart() {
super.onStart();
AlertDialog dialog = (AlertDialog)getDialog();
WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
params.height = ViewGroup.LayoutParams.MATCH_PARENT;
dialog.getWindow().setAttributes(params);
}
The problem is that the height still seems to wrap the content. The width however looks fine. This would be okay, but besides the fact that the height isn't filling the whole screen, the dialog now isn't horizontally centered anymore, but starts at the top edge of the screen.
I already tried params.gravity = Gravity.CENTER without success.
Any ideas on that?

Say your app has the permission to draw over other apps. You can draw a Drawable over anything with this simple code:
private void drawTheOverlay(Drawable drawable) {
WindowManager windowManager = (WindowManager) this.getSystemService(Service.WINDOW_SERVICE);
View view = new LinearLayout(this);
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.height = WindowManager.LayoutParams.MATCH_PARENT;
layoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
layoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
view.setBackground(drawable);
windowManager.addView(view, layoutParams);
view.setVisibility(View.VISIBLE);
}
My question is if you can draw an entire activity over another app? Meaning draw an activity, including its buttons, imageviews, child layouts, and everything in it, and make it interactable like an activity would be, but with a transparent background so that the app it's drawing over appears behind it. Is this possible?
I have a relative layout that occupies 100% of the screen. I call many custom dialogs and always works well. I get positioning and correct height and width with no problems.
However, now I need a dialog that is 100% of screen height and 100% of screen width. I get 100% width but I don't get 100% height. The maximum is around 95 of height.
I've reduced my code to a minimum for better clarity:
var lay = RelativeLayout(this)
var dial = Dialog(cx)
val win = dial.window
val wlp = win.attributes
win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
wlp.apply {
gravity = Gravity.TOP or Gravity.LEFT
x = 0
y = 0
}
win.attributes = wlp
// Here are my widgets linked to lay with lay.addView(widget).
dial.setContentView( // Connection between layout and dialog
lay, ViewGroup.LayoutParams(
screen_width, // variable with screen width in pixels
screen_height )) // variable with screen heigth in pixels
I've read many questions in Stackoverflow. What I have tried:
a) I've used MATCH_PARENT as height.
b) I've tried some windows flags:
win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
win.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN)
c) I've tried windows attribute property:
wlp.verticalMargin = 0F
No success.
PS: I also have a strange shade border at right and bottom side of dialog that I cannot get rid of it.
Update:
Rahul Khurana solution has killed the problem.
It just use
val dial = Dialog(cx,android.R.style.Theme_Black_NoTitleBar_Fullscreen)
It also eliminates the shade in other no fullscreen dialogs
val dial = Dialog(cx,
android.R.style.Theme_DeviceDefault_Dialog_NoActionBar)
Change the constructor like this:
val dialog=Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
Initialize and show your dialog as below in onStart
override fun onStart() {
super.onStart()
val dial = Dialog(this);
var width = ViewGroup.LayoutParams.MATCH_PARENT;
var height = ViewGroup.LayoutParams.MATCH_PARENT;
dial.getWindow().setLayout(width, height);
dial.show()
}
Use this snippet of code, it will work.
Activity activity = ...;
AlertDialog dialog = ...;
// retrieve display dimension
Rect displayRectangle = new Rect();
Window window = activity.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(displayRectangle);
// inflate layout
LayoutInflater inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.your_layout, null);
layout.setMinimumWidth((int)(displayRectangle.width() * 0.95f));
layout.setMinimumHeight((int)(displayRectangle.height() * 0.95f));
dialog.setView(layout);
dialog?.window?.apply {
requestFeature(Window.FEATURE_NO_TITLE); setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
setLayout(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT)
}
Good day, apologies if this seems to be a duplicate of a question that's been asked before.
I have and Android App and I am displaying a Dialog Fragment. The problem I have is that the width of the Dialog Fragment is ignored when the base activity is showing it. Here's the code in my onCreateDialog function:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Dialog dialog = new Dialog(getActivity());
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
LayoutInflater layoutInflater = (LayoutInflater) getActivity()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout2 = layoutInflater.inflate(R.layout.fragment_item_dialog, null);
dialog.setContentView(layout2);
setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialog);
Window window = dialog.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.TOP|Gravity.LEFT);
WindowManager.LayoutParams params = window.getAttributes();
params.x = 20;
params.y = 470;
params.width = WindowManager.LayoutParams.WRAP_CONTENT;
params.height = WindowManager.LayoutParams.WRAP_CONTENT;
params.copyFrom(window.getAttributes());
window.setAttributes(params);
// -- more code here
}
and here is my xml file fragment_item_dialog
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="400dp"
android:layout_height="wrap_content" >
<!--- code here ---!>
</RelativeLayout>
The height is followed properly, but Android keeps on setting the width to match parent even though I told it to wrap content. The components inside my dialog Fragment does not exceed 400dp and I have no clue why Android is forcing my layout to match parent.
Does anyone know how to work around this? Any help is very much appreciated. Thanks.
Made it work, use the same code on onStart()
#Override
public void onResume() {
// TODO Auto-generated method stub
super.onResume();
if (getDialog() == null)
return;
int width = 1100;
int height = getResources().getDisplayMetrics().heightPixels;
getDialog().getWindow().setLayout(width,
WindowManager.LayoutParams.WRAP_CONTENT);
}
I want to achieve the following design: A dialog with custom layout, created programatically. It will contain an EditText and a Button. I want the soft keyboard to pop up when the dialog appears, and I want the dialog to fill the screen horizontally and to be placed right above the keyboard.
Here is what I've done right now:
final AlertDialog obsDialog = new AlertDialog.Builder(ProdutoDetalheActivity.this).create();
final View obsLayout = View.inflate(getApplicationContext(), R.layout.observation_layout, null);
Button obsButton = (Button) obsLayout.findViewById(R.id.observation_button);
obsEdit = (EditText) obsLayout.findViewById(R.id.observation_edit);
obsButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setText(String.valueOf(obsEdit.getText()));
obsDialog.dismiss();
}
});
obsDialog.setView(obsLayout);
obsDialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
obsDialog.show();
obsEdit.requestFocus();
But this doesn't makes the dialog full width, nor calls the soft keyboard. And I still wonder how can I align the dialog with the keyboard.
I've tried these answers with no success.
Thanks in advance for any help!
[EDIT] I've brought the keyboard up by using the following code:
obsDialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
obsDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
[EDIT] Below is a printscreen of the design I want to achieve:
As far as I know, you have to adjust the dialog size/position in the code if you do not want the default size/position.
In you case specifically, you can fist declare adjustResize for the activity's windowSoftInputMode in the AndroidManifest.xml.
After that, you can set your dialog gravity at bottom and set the width in the onStart of the dialog fragment:
...
getDialog().getWindow().setLayout(mWidth, mHeight);
WindowManager.LayoutParams lp = getDialog().getWindow().getAttributes();
lp.gravity = Gravity.BOTTOM;
lp.x = 0; lp.y = 0;
getDialog().getWindow().setAttributes(lp);
...
the mWidth and mHeight are initialized in onCreate, but I think you can do it in the onStart as well. To get the width, I used below code:
Point size = new Point();
WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
display.getSize(size);
mWidth = size.x;
Hope this can meet your requirement. I used this to create a similar dialog, but I do not have a edit in the dialog. And I need it to be at the bottom of the screen.
I have an activity with ListView that has:
android:theme="#android:style/Theme.Dialog"
in Manifest.
When I open it and when it has only one line in ListView, the window that opens is very small.
How do I make the window take the whole screen?
Use this in your onCreate method of the Activity to make it full screen.
#Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.myxml);
LayoutParams params = getWindow().getAttributes();
params.height = LayoutParams.MATCH_PARENT;
params.width = LayoutParams.MATCH_PARENT;
getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
I have found that setting the window size does work, but you have to do it a bit later. In this example the window width is set to 90% of the display width, and it is done in onStart() rather than onCreate():
#Override
protected void onStart() {
super.onStart();
// In order to not be too narrow, set the window size based on the screen resolution:
final int screen_width = getResources().getDisplayMetrics().widthPixels;
final int new_window_width = screen_width * 90 / 100;
LayoutParams layout = getWindow().getAttributes();
layout.width = Math.max(layout.width, new_window_width);
getWindow().setAttributes(layout);
}
Similar to the answer from PravinCG but it can be done with one line in onCreate()...
getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
Use the suggested code before setcontentview() call. It will work.
Just a small update. Used MATCH_PARENT instead of the deprecated FILL_PARENT. PravinCG's answer worked great for me.
Yeezz ! I figured it out ! The problem is that the margin sizes are not calculated in the window widht. So If you set the layout margin to 0 and move that part to the padding of the layout the problem will be solved.
