喜欢:

progressbar.maximum = 100;

while(progressbar ! = 100)
{
    progressbar.value + 1;
}

推荐答案

默认情况下，进度条在达到100时已满.
如有必要，您可以使用android:max属性调整最大值(完整条的值)

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

android:max

定义进度可以采用的最大值.

Defines the maximum value the progress can take.

必须为整数值，例如"100".

Must be an integer value, such as "100".

这也可能是对包含值的资源(形式为"@ [package:] type:name")或主题属性(形式为?[package:] [type:] name")的引用这种类型的.

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.

<ProgressBar 
    android:id="@+id/progressbar"
    style="@android:style/Widget.ProgressBar.Horizontal"
    android:max="42"  <--- it's the answer)
    android:progress="0"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/bottom_header_relativelayout"
/>

或
probressbar.setMax(Value);
