XML:

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

    <WebView
        android:id="@+id/webView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Java:

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
LayoutInflater inflator = (LayoutInflater) getApplicationContext()
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflator.inflate(R.layout.ad, null, false);
dialog.setContentView(view);
dialog.getWindow().setGravity(Gravity.BOTTOM);
dialog.setCancelable(true);
WebView webView = (WebView) dialog.findViewById(R.id.webView);
webView.loadUrl("");
webView.setWebViewClient(new MyWebViewClient());
webView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        dialog.dismiss();
    }
});
dialog.show();

Answer 1

You can create a style for your dialog and put margins there.

For example:

<style name="custom_style_dialog"> 
    <item name="android:layout_marginStart">16dp</item>
    <item name="android:layout_marginEnd">16dp</item>
</style>

Then, in your dialog class:

class CountryDialog(
    context: Context
) : Dialog(context, R.style.custom_style_dialog) {

  //your code here
}

I did a similar smiley dialog. I extend dialog

public class SmileCustomDialog extends Dialog {
Context mcontext;
GridView mGridview;

public GridView getGridview() {
    return mGridview;
}

public SmileCustomDialog(final Context context) {
    super(context, R.style.SlideFromBottomDialog);
    this.mcontext = context;
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.emocategorydialog, null);
    mGridview = (GridView) v.findViewById(R.id.emogrid);
    mGridview.setSelector(new ColorDrawable(Color.TRANSPARENT));

    ImageAdapter mAdapter = new ImageAdapter(mcontext);
    mGridview.setAdapter(mAdapter);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.setContentView(v);

    WindowManager.LayoutParams params = this.getWindow().getAttributes();
    this.setCanceledOnTouchOutside(true);
    params.y = -100;
    this.getWindow().setAttributes(params);

}

}

But the essential is

WindowManager.LayoutParams params = yourDialog.getWindow().getAttributes(); // change this to your dialog.

params.y = -100; // Here is the param to set your dialog position. Same with params.x
        yourDialog.getWindow().setAttributes(params);

Just add this before your show your dialog.

Answer 3

WindowManager.LayoutParams:
public int x: X position... When using LEFT or START or RIGHT or END it provides an offset from the given edge
public int y: Y position... When using TOP or BOTTOM it provides an offset from the given edge
(http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#x)
thus:

final Dialog dialog = new Dialog(context);
    // ...
    // e.g. top + right margins:
    dialog.getWindow().setGravity(Gravity.TOP|Gravity.RIGHT);
    WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();
    layoutParams.x = 100; // right margin
    layoutParams.y = 170; // top margin
    dialog.getWindow().setAttributes(layoutParams);
    // e.g. bottom + left margins:
    dialog.getWindow().setGravity(Gravity.BOTTOM|Gravity.LEFT);
    WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();
    layoutParams.x = 100; // left margin
    layoutParams.y = 170; // bottom margin
    dialog.getWindow().setAttributes(layoutParams);

// etc.
