How to put an image in an AlertDialog? Android

Create one sample.xml and add ImageView in that XML.

sample.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">

    <ImageView
        android:id="@+id/dialog_imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

Java Code :

AlertDialog.Builder alertadd = new AlertDialog.Builder(MessageDemo.this);
LayoutInflater factory = LayoutInflater.from(MessageDemo.this);
final View view = factory.inflate(R.layout.sample, null);
alertadd.setView(view);
alertadd.setNeutralButton("Here!", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dlg, int sumthin) {

                }
            });

alertadd.show();

how to add the images to AlertDialog in android?

Create layout like you want then add that layout in your dialogue

Layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp" />

    <TextView
        android:id="@+id/text"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF" 
        android:layout_toRightOf="@+id/image" />

   <Button
        android:id="@+id/dialogButtonOK"
        android:layout_width="100px"
        android:layout_height="wrap_content"
        android:text=" Ok "
        android:layout_marginTop="5dp"
        android:layout_marginRight="5dp"
        android:layout_below="@+id/image" />

</RelativeLayout>

then on activity

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Bla Bla");

TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Your Text");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);

Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
dialogButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        dialog.dismiss();
    }
});

dialog.show();

Show AlertDialog with ImageView without any padding

I ended up figuring out a way to solve this issue. Because manually changing the height of the ImageView removes the extra padding, I ended up finding the dimensions of the original image, and apply them to the ImageView once the ImageView dimensions can be calculated. Here is the final result:

This is the final working code:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setPositiveButton("Get Pro", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        }).setNegativeButton("No thanks", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        final AlertDialog dialog = builder.create();
        LayoutInflater inflater = getLayoutInflater();
        View dialogLayout = inflater.inflate(R.layout.go_pro_dialog_layout, null);
        dialog.setView(dialogLayout);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        dialog.show();

        dialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface d) {
                ImageView image = (ImageView) dialog.findViewById(R.id.goProDialogImage);
                Bitmap icon = BitmapFactory.decodeResource(context.getResources(),
                        R.drawable.whygoprodialogimage);
                float imageWidthInPX = (float)image.getWidth();

                LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(Math.round(imageWidthInPX),
                        Math.round(imageWidthInPX * (float)icon.getHeight() / (float)icon.getWidth()));
                image.setLayoutParams(layoutParams);

            }
        });

And the XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ImageView
        android:id="@+id/goProDialogImage"
        android:layout_width="wrap_content"
        android:layout_height="350dp"
        android:src="@drawable/whygoprodialogimage"/>

</LinearLayout>

How can I set image URI as icon in AlertDialog box?

If you need to display an image from a url in an ImageView, I recommend you to use an image loading and caching libraries. Some well-known ones are Glide and Picasso.

Android - Alert Dialog with changeable image

You can get a reference of ImageView by calling findViewById on your view and then call setImageResource on it :

LayoutInflater factory = LayoutInflater.from(wheel.this);
final View view = factory.inflate(R.layout.alert, null);

// change the ImageView image source
final ImageView dialogImageView = (ImageView) view.findViewById(R.id.dialog_imageview);
dialogImageView.setImageResource(R.drawable.your_image);    

alertadd.setView(view);
alertadd.setTitle("Alert Dialog Title");
alertadd.setNeutralButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dlg, int sumthin) {

        }
    });

alertadd.show();
