How to make an Alert Dialog in full screen in Android?
Try below code
AlertDialog.Builder alertDialog = new AlertDialog.Builder(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
you must create a custom style for your dialog
in your style.xml
<style name="DialogTheme" parent="android:Theme.Dialog">
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">fill_parent</item>
<!-- No backgrounds, titles or window float -->
<item name="android:windowBackground">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
</style>
while inflating your dialog set this theme
dialog = new Dialog(this, R.style.DialogTheme);
【Method 1 | Use Custom Style】
In styles file:
<style name="myFullscreenAlertDialogStyle" parent="Theme.AppCompat.Light.NoActionBar"> //no actionbar, but status bar exists
<item name="android:windowFullscreen">true</item> //remove status bar
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item> //smooth animation
<item name="colorAccent">#color/colorAccent</item> //change button text color
</style>
In java file:
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(getActivity(), R.style.myFullscreenAlertDialogStyle); //second argument
【Method 2 | Use Built-In Style】
In java file:
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(getActivity(), android.R.style.Theme_Material_Light_NoActionBar_Fullscreen);
This method will make the button text become green color, you can use dialog.getButton().setTextColor() to change it.
if you're using DialogFragment to build AlertDialog you may set MATCH_PARENT on LayoutParams in onResume():
#Override
public void onResume() {
super.onResume();
ViewGroup.LayoutParams params = getDialog().getWindow().getAttributes();
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.height = WindowManager.LayoutParams.MATCH_PARENT;
getDialog().getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}

I'm trying to change the color of the AlertDialog with likely all solutions defined for this issue in stackoverflow and it still doesn't work.
This is the code I'm using to try to achieve that:
val vacationDialog = AlertDialog.Builder(fragment.context,R.style.DialogTheme)
val factory = LayoutInflater.from(OtrosDetailFragment.fragment.context);
var view = factory.inflate(R.layout.sample, null)
[...]
vacationDialog.setView(view)
val window = vacationDialog.create()
vacationDialog.setPositiveButton("Cerrar"){dialog, which ->
dialog.dismiss()
}
/**Listener called when the AlertDialog is shown**/
vacationDialog.show()
window.setOnShowListener {
/**Get the positive button from the AlertDialog**/
val positiveButton = window.getButton(DialogInterface.BUTTON_POSITIVE)
/**Set your color to the positive button**/
positiveButton.setBackgroundColor(ContextCompat.getColor(fragment.context!!, R.color.colorPrimary))
positiveButton.setTextColor(ContextCompat.getColor(fragment.context!!, R.color.colorPrimary))
positiveButton.setHintTextColor(ContextCompat.getColor(fragment.context!!, R.color.colorPrimary))
positiveButton.setLinkTextColor(ContextCompat.getColor(fragment.context!!, R.color.colorPrimary))
}
This is the style DialogTheme defined in styles.xml, in which, by the way, I cannot find a way to change the default button color (black), and seems to override any change tried from code.
<style name="DialogTheme" parent="android:Theme.Holo">
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">wrap_content</item>
<!-- No backgrounds, titles or window float -->
<item name="android:windowBackground">#color/white</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
<item name="android:gravity">center</item>
</style>
Any idea on how to approach this issue?
If you are using an AppCompat theme you can use something like:
<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#FFCC00</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#5fa3d0</item>
</style>
With the new Material components for android library you can use the new androidx.appcompat.app.AlertDialog.
Just use something like:
new MaterialAlertDialogBuilder(context)
.setTitle("Dialog")
.setMessage("Lorem ipsum dolor ....")
.setPositiveButton("Ok", /* listener = */ null)
.setNegativeButton("Cancel", /* listener = */ null)
.show();
You can customize your theme with something like:
<!-- Alert Dialog -->
<style name="MyThemeOverlay.MaterialComponents.MaterialAlertDialog" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/Widget.MaterialComponents.Button.TextButton.Dialog</item>
</style>
and:
<style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#FFFFFF</item>
<item name="backgroundTint">#color/selector_bt</item>
</style>
If you use custom layout then you can change anything easily. Follow the code below:
private fun showAlertDialog(activity: Activity){
val dialog = Dialog(activity)
dialog.setContentView(R.layout.dialog_layout)
dialog.window?.setBackgroundDrawableResource(android.R.color.transparent)
dialog.show()
}
You can create your custom layout for AlertDialog and inflate it in your custom class extending AlertDialog.
Use androidx.appcompat.app.AlertDialog rather than normal android.app.AlertDialog
I am using dialogFragment to make my own custom fragment but its size does not look like what is in priview
this is what is showing in preview
and this what happens when the dialog is shown
I want it to look exactly like my preview - what should I do?
Try this
final Dialog dialog = new Dialog(mContext, R.style.Theme_Transparent);
View view = LayoutInflater.from(mContext)
.inflate(R.layout.layout_custom_dialog, null);
dialog.setContentView(view);
Window window = dialog.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.width = wlp.MATCH_PARENT;
wlp.gravity = Gravity.TOP;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_BLUR_BEHIND;
window.setAttributes(wlp);
And add this to styles.xml file
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">true</item>
</style>

Use LayoutInflater for your custome dialog view.
AlertDialog.Builder builder = new AlertDialog.Builder(context);
final LayoutInflater inflater = activity.getLayoutInflater();
final View view = inflater.inflate(R.layout.caution_dialog, null);
builder.setView(view);
override +ve button and -ve button
AlertDialog alert = builder.create();
alert.show();
Update your style
<style name="My_search_dailog" parent="Base.V7.Theme.AppCompat.Light.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
I faced the same problem and solved it by adding "requestWindowFeature" attribute in Java file where i am showing this dialog.
Dialog dialog = new Dialog();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.show();
I am trying new AlertDialog from appcompat v7 22.1.1.
It works pretty well (In all android versions) as in image.
Style for AlertDialog is this. (For now I am using hardcoded color values instead of color resources)
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimaryDark">#111111</item>
<item name="colorPrimary">#00ddff</item>
<item name="colorAccent">#0044aa</item>
<item name="colorButtonNormal">#00aaaa</item>
<item name="colorControlHighlight">#00ddff</item>
<item name="alertDialogTheme">#style/AlertDialogTheme</item>
</style>
<style name="AlertDialogTheme" parent="Theme.AppCompat.Dialog.Alert">
<item name="colorAccent">#0044aa</item>
<item name="android:background">#ffffff</item>
<item name="android:textColorPrimary">#000000</item>
<item name="android:windowTitleStyle">#style/MyTitleTextStyle</item>
</style>
<style name="MyTitleTextStyle">
<item name="android:textColor">#0044aa</item>
<item name="android:textAppearance">#style/TextAppearance.AppCompat.Title</item>
</style>
My question is ,
1) how to change statePressed color which is rounded (Gray) in the image ?
2) No pressed color is there in android >= 21 , what is hack for this ?
3) How can I have different colors of action buttons (Is it possible)?
Any help would be great.
You can use style attributes like
buttonBarButtonStyle
buttonBarNegativeButtonStyle
buttonBarNeutralButtonStyle
buttonBarPositiveButtonStyle
Example:
<style name="dialog_theme" parent="Theme.AppCompat.Dialog.Alert">
<item name="buttonBarNegativeButtonStyle">#style/dialog_button.negative</item>
<item name="buttonBarPositiveButtonStyle">#style/dialog_button.positive</item>
</style>
<style name="dialog_button">
<item name="android:textStyle">bold</item>
<item name="android:minWidth">64dp</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingRight">8dp</item>
<item name="android:background">#drawable/dialogButtonSelector</item>
</style>
<style name="dialog_button.negative">
<item name="android:textColor">#f00</item>
</style>
<style name="dialog_button.positive">
<item name="android:layout_marginLeft">8dp</item>
<item name="android:textColor">#00f</item>
</style>
Where dialogButtonSelector is our custom drawable selector.
Unfortunatelly setting background on dialog_button destroy our paddings and margins so I need to set it again.
dialog_button style can inherit through Widget.AppCompat.Button.ButtonBar.AlertDialog but I found that it has missing styles like textStyle bold.
I have the Answer for the 3rd Questions
( How can I have different colors of action buttons (Is it possible)? )
Code:
// Initialize AlertDialog & AlertDialog Builder
AlertDialog.Builder builder = new AlertDialog.Builder(YourActivity.this);
builder.setTitle("AlertDialog Title");
...........
.........
//Build your AlertDialog
AlertDialog Demo_alertDialog= builder.create();
Demo_alertDialog.show();
//For Positive Button:
Button b_pos;
b_pos=Demo_alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
if(b_pos!=null){
b_pos.setTextColor(getResources().getColor(R.color.YourColor));
}
//For Neutral Button:
Button b_neu;
b_neu=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEUTRAL);
if(b_neu!=null){
b_neu.setTextColor(getResources().getColor(R.color.YourColor));
}
//For Negative Button:
Button b_neg;
b_neg=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE);
if(b_neg!=null){
b_neg.setTextColor(getResources().getColor(R.color.YourColor));
}
Happy Coding :)
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setMessage("Title"); builder.setCancelable(true);
builder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertdialog = builder.create();
alertdialog.show();
Button nbutton = alertdialog.getButton(DialogInterface.BUTTON_NEGATIVE);
nbutton.setBackground(getResources().getDrawable(R.drawable.btn_press_white_rect));
Button pbutton = alertdialog.getButton(DialogInterface.BUTTON_POSITIVE);
pbutton.setBackground(getResources().getDrawable(R.drawable.btn_press_white_rect));
**btn_press_white_rect.xml**
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/rounded_rect_yellow" ></item>
<item android:state_pressed="false" android:drawable="#drawable/rounded_rect_white" ></item>
</selector>
How can I reduce the height of the green title?
Activity:
final Dialog dialog = new Dialog(EditorActivity.this, R.style.dialog);
dialog.setContentView(R.layout.preference_timerange);
dialog.setTitle(getString(R.string.zmien_czas_wyprawy));
Styles.xml
<style name="dialog" parent="#android:style/Theme.Dialog">
<item name="android:windowTitleStyle">#style/dialog_title_style</item>
<item name="android:windowBackground">#color/dialog_background</item>
<item name="android:textColor">#color/dialog_text</item>
</style>
<style name="dialog_title_style" parent="android:TextAppearance.WindowTitle">
<item name="android:textSize">16dp</item>
<item name="android:background">#color/dialog_title_background</item>
<item name="android:textColor">#color/dialog_title_text</item>
</style>
I don't know how to change the height of the Dialog's title, but you can remove the whole title and create a smaller one in your layout preference_timerange.xml:
final Dialog dialog = new Dialog(EditorActivity.this, R.style.dialog);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.preference_timerange);
// Set R.string.zmien_czas_wyprawy as the title in your layout now
