This code creates a new instance of the ContentObserver class with a Handler object as its argument. The ContentObserver class is used to monitor changes to a specific content URI in the content provider. The Handler object is used to specify the thread on which the observer should be notified of any changes. In this case, the observer will be notified on the background looper thread.

getContentResolver().registerContentObserver(uri,true,new MyObserver(new Handler())); } private class MyObserver extends ContentObserver { public MyObserver(Handler handler) { super(handler); }new handler代码报错
可能是因为您没有正确导入 `Handler` 类。请确保您在代码文件的顶部添加以下导入语句:
```java
import android.os.Handler;
```
如果仍然报错,请提供更多的错误信息或代码片段,以便我能够更好地帮助您。

您好,可能是因为在您的代码中没有导入 `android.database.ContentObserver` 类。请尝试在类文件开头添加以下导入语句:
```java
import android.database.ContentObserver;
```
如果您已经导入了该类并且问题仍然存在,请提供更多的代码和错误信息以便更好地帮助您。
