this is my xml layout for popup. But i want that this layout is almost over the whole screen not just so small. How can i extend it? I call it by the code.

Answer 1

use

android:layout_width="match_parent"
android:layout_height="match_parent"

in LinearLayout

final Dialog dialog = new Dialog(MainAppActivity.this, R.style.PopupDialog);
dialog.setContentView(R.layout.popup);
dialog.setCancelable(true);
Button cancelButton = (Button)dialog.findViewById(R.id.close);
cancelButton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        dialog.cancel();
    }
});

dialog.show();

Put this in res/values/styles.xml

<style name="PopupDialog" parent="@android:style/Theme.Translucent.NoTitleBar"></style>
