Answer 1

If you are using custom view for your Alert Dialog, set the root layout height and width to wrap content and then add another child layout with fixed dimensions inside that. Then the dialog will inherit the same dimensions as the child view. And the dialog will resize according to that.

<androidx.constraintlayout.widget.ConstraintLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="400dp"
        android:layout_height="400dp"
        android:background="@drawable/popup_bg"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent">
    
    </androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

Try to below code

AlertDialog dialog = builder.create();

                // Finally, display the alert dialog
                dialog.show();

                // Get screen width and height in pixels
                DisplayMetrics displayMetrics = new DisplayMetrics();
                getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
                // The absolute width of the available display size in pixels.
                int displayWidth = displayMetrics.widthPixels;
                // The absolute height of the available display size in pixels.
                int displayHeight = displayMetrics.heightPixels;

                // Initialize a new window manager layout parameters
                WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();

                // Copy the alert dialog window attributes to new layout parameter instance
                layoutParams.copyFrom(dialog.getWindow().getAttributes());


                // Set alert dialog width equal to screen width 70%
                 int dialogWindowWidth = (int) (displayWidth * 0.7f);
                // Set alert dialog height equal to screen height 70%
                 int dialogWindowHeight = (int) (displayHeight * 0.7f);

                // Set the width and height for the layout parameters
                // This will bet the width and height of alert dialog
                layoutParams.width = dialogWindowWidth;
                layoutParams.height = dialogWindowHeight;

                // Apply the newly created layout parameters to the alert dialog window
                dialog.getWindow().setAttributes(layoutParams);

Answer 3

You can do it like:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(R.layout.dialog_change_password);

And in your Layout file give layout_height fixed.:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="250dp"
              android:layout_gravity="center"
              android:layout_marginLeft="@dimen/activity_horizontal_margin"
              android:layout_marginRight="@dimen/activity_horizontal_margin"
              android:background="@drawable/bg_otp_dialog"
              android:gravity="center"
              android:orientation="vertical">

Answer 4

You can set the Alert Dialoge using this method as .

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle("Title");
alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(600, 400);

Also you can use this after calling the alertDialog.show() method.

alertDialog.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();

lp.copyFrom(alertDialog.getWindow().getAttributes());
lp.width = 150;
lp.height = 500;
lp.x=-170;
lp.y=100;
alertDialog.getWindow().setAttributes(lp);
