問題描述
當我在布局中使用時，它指定了這個對話框 android:layout_width="match_parent" 我得到了這個對話框:
When I use in layout, which specifies this dialog android:layout_width="match_parent" I get this dialog:
我需要更寬的對話框.有什么想法嗎?
I need dialog which will be wider. Any ideas?
推薦答案
您可以通過抓取對話框使用的 Window 對象并重置寬度來實現.這是一個簡單的例子:
You can do that by grabbing the Window object that the dialog uses, and resetting the width. Here's a simple example:
//show the dialog first
AlertDialog dialog = new AlertDialog.Builder(this)
.setTitle("Test Dialog")
.setMessage("This should expand to the full width")
.show();
//Grab the window of the dialog, and change the width
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
Window window = dialog.getWindow();
lp.copyFrom(window.getAttributes());
//This makes the dialog take up the full width
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
window.setAttributes(lp);
這是最終結果.請注意，如果您需要微調某些內容(例如更改背景等)，您可以對對話框進行更多樣式設置.當我過去不得不這樣做時，我通常使用這種方法，并在構建器類上使用 setView() 自定義對話框中使用的布局.
Here's the end result. Note that there's a lot more styling you can do to the dialog if you need to fine tune things (like change the background, etc). When I've had to do this in the past, I usually use this method, and customize the layout used in the dialog with setView() on the builder class.
