如何在android中对齐自定义对话框中心？

概述我正在处理应用程序,我想将对话框显示为屏幕大小.所以我使用下面的代码.我通过这里得到了解决方案 Alert message is not displaying in alert dialog box? AlertDialog.Builder builder = new AlertDialog.Builder(this); TextView title = new TextView(this 我正在处理应用程序,我想将对话框显示为屏幕大小.所以我使用下面的代码.我通过这里得到了解决方案 Alert message is not displaying in alert dialog box?

AlertDialog.Builder builder = new AlertDialog.Builder(this);    TextVIEw Title = new TextVIEw(this);    Title.setText("DM2");    Title.setBackgroundcolor(color.DKGRAY);    Title.setpadding(10,10,10);    Title.setGravity(Gravity.CENTER);    Title.setTextcolor(color.WHITE);    Title.setTextSize(20);    TextVIEw text = new TextVIEw(this);      text.setText("Hello This text");      text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));    text.setTextSize(20);            text.setGravity(Gravity.CENTER);    //Creates a linearlayout layout and sets it with initial params    linearLayout ll = new linearLayout(this);    ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));    ll.setGravity(Gravity.CENTER);    ll.addVIEw(text);     builder.setCustomTitle(Title);    builder.setPositivebutton(            "Ok",new DialogInterface.OnClickListener() {                public voID onClick(DialogInterface dialog,int ID) {                    dialog.dismiss();                }            });     Dialog d = builder.setVIEw(ll).create();    //Fills up the entire Screen    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();    lp.copyFrom(d.getwindow().getAttributes());    lp.wIDth = WindowManager.LayoutParams.FILL_PARENT;    lp.height = WindowManager.LayoutParams.FILL_PARENT;    d.show();    d.getwindow().setAttributes(lp);

但我希望对话框出现在中心对齐的位置.现在它显示在窗口的顶部.@H_301_5@我尝试使用lp.garvity = Gravity.center,但没有用.@H_301_5@如果设备方向改变,我需要再按ok按钮关闭对话框.如何解决这个问题？

提前致谢@H_301_5@普什帕

解决方法 我迟到了,但是迟到的时候再好不过了:-) @H_301_5@你可以使用下面的代码:(我也看到了 here)

dialog = new Dialog(activity,androID.R.style.theme_Translucent_NoTitlebar);dialog.setContentVIEw(R.layout.activity_upload_photo_dialog);Window window = dialog.getwindow();window.setLayout(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);window.setGravity(Gravity.CENTER);//The below code is EXTRA - to dim the parent vIEw by 70%LayoutParams lp = window.getAttributes();lp.dimAmount = 0.7f;lp.flags = LayoutParams.FLAG_DIM_BEHIND;dialog.getwindow().setAttributes(lp);//Show the dialogdialog.show();

希望我帮忙……
