Answer 1

This can be considered as a simple hack to set your layout width for example 1000dp and height wrap content like :

<LinearLayout
    android:layout_width="1000dp"
    android:gravity="center"
    android:padding="10dp"
    android:background="@color/colorAccent"
    android:orientation="vertical"     
    android:layout_height="wrap_content">

Answer 2

In case anyone is wondering how to do it for a dialog shown using DialogFragment, you can override onCreateDialog to return a Dialog with custom style that has windowMinWidthMajor and minor set to 90%

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new Dialog(getActivity(), R.style.WideDialog);
}

Style:

<style name="WideDialog" parent="Base.Theme.AppCompat.Dialog">
    <item name="android:windowMinWidthMajor">90%</item>
    <item name="android:windowMinWidthMinor">90%</item>
</style>

Answer 3

You don't need to add any style for that just try below one

  Dialog dialog = new Dialog(context);
  dialog.setContentView(R.layout.your_layout_here);
  dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  dialog.show();

Note: using empty style is memory time consuming inside the processor. Instead directly use dailog.getWindow().setLayout(width,height).

Answer 4

MyDialogFragment myDialogFragment = 
    new MyDialogFragment(activity,arraylist.get(position).getImage());
                                myDialogFragment.show();

Window window = myDialogFragment.getWindow();
        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

Answer 5

Just try to wrap your dialog layout in a RelativeLayout

Answer 6

For full width dialog you can create custom style for dialog. Code is given below for full width dialog:

<style name="Custom_Dialog" parent="ThemeOverlay.AppCompat.Light" >
    <item name="windowMinWidthMajor">100%</item>
    <item name="windowMinWidthMinor">65%</item>
</style>

To assign this style to the dialog's constructor, add this to onCreate() method right after setContentView():

getWindow()
    .setLayout(
        ViewGroup.LayoutParams.FILL_PARENT,
        ViewGroup.LayoutParams.WRAP_CONTENT
    );
