ProgressBar在模拟器而不是手机上运行

Question

I've got this code:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="56dp"
android:minWidth="56dp">
<ProgressBar android:layout_width="32dp"
    android:layout_height="32dp"
    android:layout_gravity="center"/>

The spinning progressbar runs fine when i run my application in Droid4X emulator, but it doesn't show any spinning progressbar on my phone. Tried another phone too, no progressbar. Can you help me finding my problem? Thanks

To be precise it works on every API except 23. To be even more precise, it works if i put

        style="@android:style/Widget.ProgressBar.Small"

Answer 1

您的代码可以在我的手机上正常工作，我认为问题不在此代码中。

Answer 2

It is also working on my Android Moto G. And there is if problem persists than do not run on emulator rather connect your phone with Android studio and enable

Developer Mode

and than select device as your phone. If any problem will be it will debug.
