I build an alertDialog in this way:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/title1"
android:textSize="20sp"
android:textColor="#color/white" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/chars1" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/RelativeLayout1"
android:background="#drawable/body_white">
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/Layout1"
android:layout_centerHorizontal="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/img1"
android:id="#+id/img1"
android:layout_alignParentTop="true"
/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/img2"
android:background="#drawable/img2"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/img1"
android:layout_toEndOf="#+id/img1" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
I want to do this thing:
img1 = (ImageView) findViewById(R.id.img1);
But doing this I receive a NullPointerException.
I used this:
(EditText)((Dialog) dialog).findViewById(R.id.username);
in a early application where I take value after click.
In this case I don't have an object DialogInterface dialog. So I can't use it. How can I fill img1?
I want so set manually padding but I want to do this in JAVA and not in XML.
Thanks
Edit:
This is method that launch alertDialog:
public void createDialog() {
alertDialog = new AlertDialog.Builder(Instructions.this);
LayoutInflater inflater = this.getLayoutInflater();
alertDialog.setView(inflater.inflate(R.layout.alert_dialog_layout, null));
n1Dialog = (ImageView) findViewById(R.id.img1);
n1Dialog.setPadding(0,0,0,0);
alertDialog.show();
}
I have a simple button that when in onClick() method have
createDialog();
Row with setPadding (that is only a proof, it isn't what I want to do) was mistaken because is NullPointerException
do like this:
alertDialog = new AlertDialog.Builder(Instructions.this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView=inflater.inflate(R.layout.alert_dialog_layout, null);
alertDialog.setView(dialogView);
n1Dialog = (ImageView) dialogView.findViewById(R.id.img1);
n1Dialog.setPadding(0,0,0,0);
alertDialog.show();
This is how you should inflate a custom view for a AlertDialog:
Builder myCustomDialog = new AlertDialog.Builder(yourContext);
LayoutInflater factory = LayoutInflater.from(context);
final View yourInflatedView = factory.inflate(R.layout.your_xml_layout, null);
//Here you get your imageView (or TextView, EditText,...)
ImageView img1 = (ImageView) yourInflatedView.findViewById(R.id.img1);
// Do stuff with your imageview...
myCustomDialog.setView(yourInflatedView);
myCustomDialog.show();
You can create the dialog in the following way also:
public void displayPopup(Context ctx) {
Dialog cd_display = new Dialog(ctx);
cd_display.requestWindowFeature(Window.FEATURE_NO_TITLE);
cd_display.setContentView(R.layout.alert_dialog_layout);
ImageView n1Dialog = (ImageView) cd_display.findViewById(R.id.img1);
cd_display.show();
}

I'm trying to display a custom Dialog. I replicated a class which perfectly works and used it for this dialog but it don't display anything but a little box in the middle of the screen.
I can't figure out what's wrong....
Dialog onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
final View v = inflater.inflate(R.layout.fleet_select_dialog, null);
WindowManager windowManager = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
Display display = windowManager.getDefaultDisplay();
int width = (display.getWidth() );
int height = (display.getHeight() );
getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,(width/3)*2 );
}
xml layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

the dialog is used like this:
fleetSelectDialog = new FleetSelectDialog(context);
fleetSelectDialog.show();
what am I doing wrong??
Try setting the windowLayout of the dialog before you set the content view with the inflater.
You can create your view directly from the Layout Inflater, you only need to use the name of your layout XML file and the ID of the layout in file.
Use the following code to set the layout of your AlertDialog
LayoutInflater inflater = getLayoutInflater(); View dialoglayout = inflater.inflate(R.layout. fleet_select_dialog, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();
I accidently deleted one important line:
this.setContentView(v);
final Dialog dialog = new Dialog(mContext);
// hide to default title for Dialog
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
// inflate the layout dialog_layout.xml and set it
// as contentView
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.customize_dialog, null, false);
dialog.setCanceledOnTouchOutside(false);
dialog.setContentView(view);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
dialog.show();
Enjoy full code.
Cheers !
I created a custom dialog but I got an unexpected result.
The final appearance of the dialog is:
As you can see, my custom dialog is shown with a kind of padding in both top and bottom of the dialog, and I don't code it to do this...
The code is the next:
#Override
protected Dialog onCreateDialog(int id){
LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View newAsig = inflater.inflate(R.layout.nuevaasignatura_act, null);
//Also, down here I tried to shape the dialog by setting a functional resource, but
//the stroke should be blue, not grey.
RelativeLayout re = (RelativeLayout)newAsig.findViewById(R.id.layoutCrearAsig1);
re.setBackgroundResource(R.drawable.borde);
Typeface tf = Typeface.createFromAsset(getAssets(), "Roboto-Light.ttf");
ImageView ico = (ImageView)newAsig.findViewById(R.id.ivicono);
ico.setBackgroundResource(R.drawable.colorprincipal);
LinearLayout ly = (LinearLayout)newAsig.findViewById(R.id.layoutCrearAsig2);
ly.setBackgroundColor(Color.rgb(214, 217, 224));
TextView txt = (TextView)newAsig.findViewById(R.id.textviewnuevaasig);
txt.setTypeface(tf);
TextView txt1 = (TextView)newAsig.findViewById(R.id.textViewCarpeta);
txt1.setTypeface(tf);
txt1.setBackgroundResource(R.drawable.colorprincipal);
Button btn = (Button)newAsig.findViewById(R.id.buttonCrearAsig);
btn.setTypeface(tf);
switch (id){
case 0:
return new AlertDialog.Builder(this)
.setView(newAsig).create();
}return null;
And the XML file...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

I hope you can help me. Thanks!
The idea is AlertDialog always has 5dp top and bottom padding.
Try something like this:
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setView(newAsig, 0, 0, 0, 0);
Try this validation.
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
builder = new AlertDialog.Builder(getActivity());
builder.setInverseBackgroundForced(true);
} else {
builder = new AlertDialog.Builder(getActivity(), AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
}
}
I want to create a different theme for all of alertDialog instances. I need my own title view instead of the usual black title background. All text should have a blue color, and set the edge of the alertDialog to a round shape.
Is it possible to create our own theme for alert dialogs, using any style or creating a class which extends AlertDialog.Builder? I need a common theme or style for my all instances of alertDialog. I am using alertDialog in many places - one for singleChoice items, one with ArrayAdapter.
My alertDialog with array adapter:
String[] items = {"Edit profile","Change user","Change password","Logout"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(Loged.this,
R.layout.my_spinner_layout, items);
settingMenu.setAdapter(adapter, listener);
My alertDialog with single choice items:
alertDelete = new AlertDialog.Builder(getParent());
alertDelete.setTitle("Delete");
alertDelete.setCancelable(true);
CharSequence[] choice = {"this user","All user"};
alertDelete.setSingleChoiceItems(choice, 0,
For my all alertDialog, I need a common theme, like:
please check this link. here am creating my own alertDialog class
and its a simple method if you reuse the alertDialog in many situation in your application
how Create setAdapter() for a AlertDialog
I solved my problem by creating a class which extends Dialog, and I created my own functions. for example setMessage,setTitle,setPositiveButton,setNegativeButton etc.
But am confusing on how we can replace the setAdapter() and setSingleChoice().
Here one example For Dialog:
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Give a Title...");
// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Put here any custom text!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.ButtonOK);
// if button is clickedthen dialog will closed
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
});
Custom AlertDialog
AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext;
LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View urlayoutfile = inflater.inflate(R.layout.custom_dialog_xmlfile,(ViewGroup)findViewById(R.id.Yourlayout_id));
builder = new AlertDialog.Builder(this);
builder.setView(urlayoutfile);
alertDialog = builder.create();
alertDialog.show();
To use a specific style, use
ctw = new ContextThemeWrapper(this, R.style.MyStyle);
new AlertDialog.Builder(ctw)
.setTitle(...)
You can use layout as Different themes, styles, Backgrounds

I'm trying to use a PopupWindow with a Gallery inside, but when inflating the popup, I get the following error:

This doesn't necessarily answer your question, but why don't you use a dialog?. It's prettier and easier to use.
Edit 1: Yes you should be able to use a gallery in a popup window, I'm not sure why you can't get it to work.
How can I change the background color for an alertbox's title bar?
AlertDialog.Builder alert=new AlertDialog.Builder(getParent());
alert.setTitle("sample");
alert.show();
The easiest way is to subclass a dialog by creating a class which extends dialog and implements the constructor which take style as a parameter. Then make your own custom layout to it.
The Code to show the dialog:
private void showDialog()
{
Custom_Dialog dialog = new Custom_Dialog(this, R.style.myCoolDialog);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Custom Dialog");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
dialog.show();
}
The code for the subclass:
package com.stackoverflow;
import android.app.Dialog;
import android.content.Context;
public class Custom_Dialog extends Dialog {
protected Custom_Dialog(Context context, int theme) {
super(context, theme);
// TODO Auto-generated constructor stub
}
}
the style: myCoolDialog.xml
<resources>
<style name="myCoolDialog" parent="android:Theme.Dialog">
<item name="android:windowBackground">#drawable/blue</item>
<item name="android:colorForeground">#f0f0</item>
</style>
</resources>
and last the layout:custom_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_root"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
>
<ImageView android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="10dp"
/>
<TextView android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#FFF"
/>
</LinearLayout>
You can just set custom title like this
LayoutInflater inflater = this.getLayoutInflater();
View titleView = inflater.inflate(R.layout.custom_title, null);
new AlertDialog.Builder(SubCategoryActivity.this)
.setCustomTitle(titleView);
and in custom_title layout you can create custom title like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:id="#+id/llsubhead"
android:background="#color/colorPrimary">
<TextView
android:id="#+id/exemptionSubHeading4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:layout_weight="1"
android:text="Exemption Sub Head"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/white" />
</LinearLayout>
</LinearLayout>
From the answer #CornflakesDK and #ice spirit, I thought you can use the current AlertDialog.Builder implementation to do the custom dialog and make it easy to maintain.
CustomDialogBuilder.java
public class CustomDialogBuilder extends AlertDialog.Builder {
private View view;
public CustomDialogBuilder(Context context) {
super(context);
view = LayoutInflater.from(getContext()).inflate(R.layout.custom_dialog_title, null);
setCustomTitle(view);
}
#Override
public Builder setTitle(int titleId) {
TextView titleTextView = view.findViewById(R.id.exemptionSubHeading4);
titleTextView.setText(getContext().getString(titleId));
return this;
}
#Override
public Builder setTitle(CharSequence title) {
TextView titleTextView = view.findViewById(R.id.exemptionSubHeading4);
titleTextView.setText(title);
return this;
}
}
custom_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:orientation="vertical">
<LinearLayout
android:id="#+id/llsubhead"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:background="#color/black"
android:orientation="vertical">
<TextView
android:id="#+id/exemptionSubHeading4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_margin="15dp"
android:layout_gravity="center"
android:text="Exemption Sub Head"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/white" />
</LinearLayout>
</LinearLayout>
Inside your activity code,
new CustomDialogBuilder(MyActivity.this)
.setTitle(R.string.actions)
.setItems(R.array.items_actions, (dialog, which) -> {
// handle items
}).create().show();
Then, you can have styling inside the DialogBuilder and also utilize the functions of the AlertDialog.Builder.
