回答by Pepelac
By default, the progress bar is full when it reaches 100.
If necessary, you can adjust the maximum value (the value for a full bar) using the android:max attribute
默认情况下,进度条在达到 100 时为满。
如有必要,您可以使用 android:max 属性调整最大值(满条的值)
android:max
android:max
Defines the maximum value the progress can take.
定义进度可以采用的最大值。
Must be an integer value, such as "100".
必须是整数值,例如“100”。
This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.
这也可能是对包含此类型值的资源(以“@[package:]type:name”形式)或主题属性(以“?[package:][type:]name”形式)的引用.
<ProgressBar
android:id="@+id/progressbar"
