How to align custom dialog centre in android ?
提问by pushpa
I am working on the application where i wanted to display the dialog to be screen size. So i used code below.I got the solution through here Alert message is not displaying in alert dialog box?
我正在处理我想将对话框显示为屏幕大小的应用程序。所以我使用了下面的代码。我通过这里得到了解决方案警报消息未显示在警报对话框中？
AlertDialog.Builder builder = new AlertDialog.Builder(this);
TextView title = new TextView(this);
title.setText("DM2");
title.setBackgroundColor(Color.DKGRAY);
title.setPadding(10, 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);
But I want dialog to be appeared in center aligned. Now it is display in top of the window. I tried with lp.garvity = Gravity.center, but didn't work. and If the device orientation changes, i need to press ok button more time to close the dialog. How to fix this?
但我希望对话框以居中对齐的方式出现。现在它显示在窗口顶部。我试过 lp.garvity = Gravity.center，但没有用。并且如果设备方向发生变化，我需要按确定按钮更多时间来关闭对话框。如何解决这个问题？
Thanks in advance Pushpa
提前致谢

I'm little late, but better late then never :-) you can use the code below: (I saw also here)
我有点晚了，但迟到总比没有好:-)你可以使用下面的代码：（我也在这里看到）
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 dialog
dialog.show();
Hope I helped...

This works for me:
这对我有用：
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
回答by Sebastian Breit
Maybe this works:
也许这有效：
WindowManager.LayoutParams WMLP = dialog.getWindow().getAttributes();
WMLP.gravity = Gravity.CENTER_HORIZONTAL|Gravity.CENTER_VERTICAL
dialog.getWindow().setAttributes(WMLP);

Note:- This is for "custom layout"... :)
注意：- 这是用于“自定义布局”... :)
I was struggling with the same, and after struggling for hours i came to this result
我也在为此苦苦挣扎，在挣扎了几个小时后，我得出了这个结果
Earlier i was creating the dilaoge like this : -
早些时候，我正在创建这样的 dilaoge：-
final Dialog dialog = new Dialog(PopupforeditActivity.this);
After adding style "No titleBar" it started fetching the layout the way I had created.
添加样式“No titleBar”后，它开始以我创建的方式获取布局。
For this you have to create the layout with params "fillParent" and create the dialoge like this
为此，您必须使用参数“fillParent”创建布局并创建这样的对话框
final Dialog dialog = new Dialog(PopupforeditActivity.this,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
dialog.setContentView(R.layout.dialog_billing_cart);
dialog.setCancelable(true);
The above is coding part
以上是编码部分
You in Layoutpart
put your whole layout in RelativeLayout
您Layout部分地将整个布局放入RelativeLayout
and give your layout property android:layout_centerInParent="true"
并提供您的布局属性 android:layout_centerInParent="true"
Ex:-
前任：-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/transparent" >
<!--Your Layout-->
<ScrollView
android:id="@+id/scrlView_FormHolder"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp" >
</ScrollView>
</RelativeLayout>
And if you don't want to miss "title" You can have that in your custom layout as TextView ..
如果您不想错过“标题”，您可以在自定义布局中将其作为 TextView ..
Hope it will help.. As it helped me :)
希望它会有所帮助..因为它帮助了我:)
