我无法更新进度条。
我尝试了很多解决方案，但它仍然没有帮助，所以我认为这是一个我完全失踪的问题。我刚刚添加了整个代码，以便您更好地了解我在这里所做的事情。我很新，所以我专注于让它先工作并稍后设计。
这是我的代码：

请让我知道你的想法！

查看this，了解如何在工作线程中正确更新ProgressBar。
在run（）方法内仅按setProgress(mProgressStatus);
run（）方法中唯一的代码是
setContentView(R.layout.activity_main);这与你想要实现的内容有些无关，而你在run（）方法之外还有其他一切。 ProgressBar的属性定义为XML布局文件，因此您无需setMax()。

首先是像这样的drawable / progress_layout
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background"
android:drawable="@drawable/progressimage"/>
<item android:id="@android:id/progress">
<clip android:drawable="@drawable/progressimage" />
</item>
然后
Handler handler = new Handler() {};
handler.postDelayed(new Runnable() {
public void run() {
ProgressBar progress = (ProgressBar) findViewById(R.id.progressBar2);
progress.setIndeterminate(false);
progress.setMax(100);
progress.setProgress(20);
progress.setMax(50);
progress.setProgress(50);
setContentView(R.layout.activity_main);
}
} , 2000);
有很多语法问题
