java代码:

    

private Dialog mDialog;private void showDeleteDlg() {mDialog = new Dialog(MainActivity.this, R.style.Theme_Dialog);mDialog.setCanceledOnTouchOutside(true);View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.xml_dialog, null);login = (Button)view.findViewById(R.id.my_login);cancle = (Button)view.findViewById(R.id.my_cancle);login.setOnClickListener(this);cancle.setOnClickListener(this);mDialog.setContentView(view);mDialog.show();}

style.xml

    <style name="Theme_Dialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
